EXTRAPOLATING THE TRENDS OF THE MOST 
SIGNIFICANT PATTERNS OF WORLD HISTORY   


------------------------------------------------------------ 
Abstract:   
The possibility of the very protracted existence of  
civilizations is examined and in the case of the largest ones 
(European, Middle Eastern, East Asian, South Asian, Sub-
Saharan African, Central Asian) it is found to be probable. 
The long-term evolutionary stages of these civilizations are 
listed, in the case of the European civilization the usual 
historical periodization (Neolithic, Antiquity, Medium Age, 
Modern Age) is acceptable, but in the case of the others a 
different periodization (Neolithic, Antiquity, Age of  
Expansion) seems to be more satisfactory. A "halving rule of 
the ages" is found (the duration of an age is half of the 
duration of the previous one). The theory of the "periodical 
(European) world wars" is examined, recent results are 
surveyed. The lifetimes of the great empires (without and 
with successor states) are determined, extrapolations are 
made for the "modern empires". The large conflict  zones  
(shatterbelts: East-central Europe, Middle East, East Asia, 
South-east Asia, South Asia, Sub-Saharan Africa, Middle 
America) are surveyed, the hypothesis of the "periodical 
crisis sequences" is examined.

1.  Introduction 

Traditional historiography usually amasses long descriptions 
of  numerous events. Historians typically add some 
explanations to their descriptions (stating that some events 
were more important than others,  establishing causal 
relationships etc.) but these explanations tend to be too 
particular. Since a long time exists a demand for a more 
"systematic" historiography. Among the numerous experiments 
probably the most significant is the description using  
"civilizations". This method appeared in the 19th century 
(e.g. in the works of N. Danilevsky), but the most 
significant books based on this idea were published in the 
first half of the 20th century. Probably the best known 
example is the work of  A. Toynbee [1].  A typical problem 
with this "civilizationist" descriptions is the assumption 
that civilizations are "born", "living" and "dying" like 
humans and this is happening in a historically not too long 
time. This assumption contradicts with a very common feature 
of the traditional descriptions of national histories: they 
frequently claim that the "core" of  the nation exists 
continuously since prehistoric times (one could mention here 
many examples from Ireland to Japan). In spite of the many 
successes of the 19th and 20th century archaeology  it is 
very difficult to determine the truth about prehistory, but 
it seems probable that  such statements are not quite 
unfounded (at least if we interpret the notion of  "core" not 
as a "sovereign state" but as a "culturally identifiable 
ethnic group").  Recently  D. Wilkinson created a 
civilizational theory which describes civilizations as 
continuous entities from prehistoric to modern times (see 
[2]).  Unfortunately, his theory has an other difficulty: he 
assumes that political and military contacts between 
civilizations inevitably cause the "merging" of the 
contacting civilizations i.e. now exists only one "Central 
Civilization". This again contradicts with the common 
experience: if (for example) Germans and Italians can live 
next to each other for thousands of years without merging 
into a single nation then why should civilizations merge?  

In order to avoid these problems one should identify (at 
least) the "major civilizations" which can be  traced back  
to prehistoric times. "Civilizations" are usually defined as 
"cultures with complex social structures (states with 
significantly specialised labour-division schemes)".  "Major 
civilizations" can be those civilizations which produced 
"great powers" (in the usual politico-military sense) during 
their histories. But  in prehistoric times "civilizations" 
did not exist, therefore we should examine the "cultures".  
Interpreting the notion of  "culture" as the archaeologists 
do would lead to a hopeless confusion (there are thousands of 
archaeologically identified cultures). But the common meaning 
of  "culture" (which doesn't contradict with the 
"archaeological meaning") can be covered with a rather simple 
definition: "culture is what people have in common (but not 
with everybody)". In this case we can say that the major 
cultures are the major human races because biological 
features are the most basic "commons" what people may have. 
In order to avoid misunderstandings the followings should be 
noted: 

  - The author doesn't think that certain races  are more 
valuable  than others. 
  - The author doesn't think that  "culture" is biologically 
determined. But culture is the result of common efforts: we 
learn it from each other, we practice it (usually) by 
acting together etc. Any common efforts are strongly 
facilitated by the feeling that we belong to the same group 
and common biological features are obvious sources of such 
a feeling. 

The major human races (i.e. those which occupy large 
territories and have large populations) are the followings:  
African, East Asian, European, Middle Eastern, South Asian.  
Anthropologists usually consider the "European" and the 
"Middle Eastern" as a single race but because of the very 
significant cultural differences here we must separate them. 
This classification is a good start: all of the mentioned 
groups have produced "great powers" during their histories. 
But if it is compared to the lists of civilizations produced 
by the "classical" civilizationists then it seems to be 
rather crude. In order to refine it (to identify more closely 
the social groups which produce "great powers") one must 
examine each racial group separately.  


2.  Listing the (sub)civilizations  

It is better to begin with the European civilization because 
European history is probably the best documented (and 
certainly the most detailedly analysed) case of 
historiography. European civilization is a highly mobile 
phenomenon: the distance between the oldest (Antique Greece) 
and newest (20th century USA) great powers is more than 8000 
kms. Therefore the European subcivilizations are usually 
differentiated on the basis of religion: Catholic, Orthodox, 
Protestant. This grouping covers only the Modern Age (in the 
strict sense there were no Protestants before Luther 
published his theses) but if one draws the division lines 
between these groups on the map of Europe then it is visible 
that this religious division has a geographic meaning, too: 
South-western and Central Europe is Catholic, South-eastern 
and Eastern Europe is Orthodox, Northern and North-western 
Europe is Protestant. This geographic divisioning can be 
extended to the areas conquered (and populated) by Europeans 
in the Modern Age: Latin America can be considered as the 
extension of South-western Europe, North America as the 
extension of North-western Europe, Siberia as the extension 
of Eastern Europe. What is more important, this divisioning 
can be extended in time, too. The border between the Eastern 
and Western Roman Empire was officially drawn only in 395, 
but significant cultural differences existed between the 
Eastern and Western Mediterranean regions many hundred years 
before it, too. The peoples of Northern Europe were also 
prominent in the Antiquity, Celts and Germans many times 
played an important role in the history of that age. In their 
best days they certainly can be considered (at least) as 
"strong regional powers" (e.g. when the Germans destroyed the 
legions of  Varus in the Teutoburger forest), but what is 
even more important, they were able to maintain their 
independence in spite of the Roman colonisation efforts. In 
the Early Medium Age this threefold divisioning is not very 
obvious but if one looks at the map of Europe in 800 CE (in 
[3]) then it is visible that the "large" cities (over 15000 
inhabitants) in the territories ruled by Christians form 
three major groups: one in North-western Europe (in the 
Paris-Cologne region), one in Italy (Milan, Rome etc.) and 
one in the Byzantine Empire (from Cherson to Syracuse, with 
Constantinople as the largest city of Europe). This indicates 
that the major urban cultures followed this threefold 
geographic divisioning even in that rather troublesome age of 
European history. 

The other major civilizations are much less mobile therefore 
a similar geographic divisioning is less problematic. In the 
Middle East great powers usually emerge in the following 
regions: Egypt, Mesopotamia, Iran, Anatolia (these names here 
must be interpreted as strictly geographical terms, such 
terms as "northern Nile valley" or "Iranian plateau" would be 
more precise but rather awkward). These areas also show  
remarkable ethnic continuity (except Anatolia), roughly the 
same ethnic groups inhabit them since the early Antiquity, 
therefore we can hope that their histories will show some 
repetitive patterns. In East Asia the significant geographic 
regions are the followings: China, Japan, Central Asia (the 
Mongolia-Kazakhstan region), South-east Asia (the Burma-Java-
Philippines triangle). The latter is an ethnically (and 
historically) quite diverse region, probably should be 
divided into smaller parts, but real great powers never 
emerged in that region, only (stronger or weaker) regional 
powers, therefore from our viewpoint such a finer division is 
not necessary. 

The nomad culture of the Central Asian peoples differs very 
significantly from the urban cultures prevailing in the other 
parts of Asia, therefore it is better to discuss the "Central 
Asian" as an entirely separate civilization. It must be noted 
here that not all the nomadic peoples of the Eurasian steppe 
region can be considered as part of the Central Asian 
civilization. The "original" (Neolithic) racial composition 
of these peoples was quite varied: there were European nomads 
in Southern Russia (the name "Russia" is meant here as a 
geographic term which includes Eastern Europe and Western 
Siberia), there were Middle Eastern (pre-Turkic) nomads in 
the Kazakhstan-Turkmenistan region and Asian nomads existed 
probably to the east of the Altai mountains only. But  there 
was a general tendency among these peoples to wander 
(typically westward) into the territories of sedentary 
cultures where (if  they were able to conquer the attacked 
state) they settled as a new  "ruling class". Such settlings 
occurred only when the nomad tribes reached a certain level 
of social development  (early nomads never settled down), 
different groups of nomads reached this level of development 
at different times, Indo-Europeans earlier, Asians later (see 
[10], [18]).  Therefore by that time when the really great 
nomadic empires were formed the Asian nomads became 
predominant. 

 In India the truly Indian great powers usually united 
(almost) the whole subcontinent therefore a geographic 
subdivision is not necessary. In Sub-Saharan Africa the 
vastness of the continent  and the ethnic diversity of the 
population certainly justifies some subdivision, but  no 
great powers emerged there and the historical data about the 
significant states (regional powers) of Black Africa is 
rather unsure, therefore  we may omit the subdivision of 
Africa, too. It must be noted here that some  
civilizationists simply ignore the African civilization 
(probably because of  the scarcity and uncertainty of the 
historical and archaeological data). 

After all these considerations, the list of  the major 
civilizations and their sub-civilizations is the following: 
  - European (Catholic / Orthodox / Protestant or Southern / 
    Eastern / Western in geographic terms) 
  - Middle Eastern (Egyptian / Mesopotamian / Iranian / 
    Anatolian) 
  - Central Asian 
  - East Asian (Chinese / Japanese / South-eastern) 
  - Indian (South Asian) 
  - Black African (Sub-Saharan)  
The (native) American civilizations are not listed here 
because they never created "great powers" on the global 
level (with a 3000 years "technology lag" it is not 
possible) and they might be extinct now.  
All the other civilizations still exist, but 
the Central Asian one  probably will be extinct in a 
"historically not too long" time. But  in Outer Mongolia 
exists an independent Mongolian state even today  (although 
it's independence is due to the Russian - Chinese rivalry, 
not to it's own strength) and many subjects of it still live 
as nomads.   

Now it is possible to analyse the individual histories of 
each civilization. But instead of going into the innumerable 
details (which would certainly lead to nowhere), we should 
concentrate on the "most important" events. Such "most 
important" events could be the followings: 

  - events / processes closely related to the existence of 
    the civilization 
  - events / processes closely related to the existence of 
    the great powers of the civilization 
  - events / processes closely related to the (relative) 
    status of the great powers of the civilization 

This list may seem subjective, but the followings should be 
noted: 

  - This method is consistent with the traditional method of 
historiography. Conventional "world histories" are 
practically histories of the great powers, and historians 
usually comment on the importance of the various events 
(and the most decisive "commenting" happens before the 
writing: firstly they decide what is important enough to 
write it down). 

  - If we find some repeating patterns / events (without 
ignoring many details it would be impossible - history 
never repeats itself exactly) then we may extrapolate these 
patterns into the future. If the predicted events really 
occur (we or our descendants certainly will see it) then it 
will be a strong indication of the theory's correctness. 
Historians and social scientists usually refrain from 
predictions, knowing the extreme complexity of their 
subject.  But this refraining doesn't mean that repeating 
patterns don't exist. Great individuals certainly have 
their roles in history but without supporting masses they 
would get nowhere and if there are masses then there are 
statistical laws. 


3.  Long-term processes  

Firstly we should examine the major "turning points" in the 
histories of the civilizations. Here again the best start is 
the European civilization. In the traditional historiography 
European history is divided into three major ages: Antiquity, 
Medium Age, Modern Age. The Neolithic can be added as the 
first age. Neolithic societies also were based on surplus-
producing economies, many important innovations appeared in 
that age (bronze and iron working, utilisation of animals for 
traction and riding, simple methods of long-distance 
navigation etc.) and also many important features of the 
Antique societies appeared in primitive forms (social 
stratification, cities, long-distance trade etc.).  It is 
generally agreed that the Medium Age ends with Columbus 
(reaching America in 1492) or with Luther (publishing his 
theses in 1517), i.e. the approximate starting date of the 
Modern Age is 1500 CE. The starting date of the Medium Age is 
usually assumed to be 476 CE (deposition of Romulus 
Augustulus by Odoacer) but other dates also can be suggested 
(Christianity becoming the state religion of the Roman Empire 
in 391, partitioning of the Roman Empire to Eastern and 
Western Empires in 395, or the final fall of the Ostrogothic 
kingdom in 553). Therefore the approximate starting date of 
the Medium Age can be 500 CE.  

There is no generally agreed date for  the beginning of the 
Antiquity  but it is reasonable to assume that it started 
with the appearance of the first major urban cultures in the 
Balkan peninsula, i.e. with the Minoans or with the 
Mycenaeans. The origin of the Minoans is unknown, it is 
frequently assumed that they came from the Middle East (from 
Anatolia? from Syria?) but it is also possible that the 
Minoan culture was the result of the original Neolithic 
population's internal development (see [4]). The origin of 
the Mycenaeans is much more certain: since the deciphering of 
their writing (the Linear B) by M. Ventris (see [5]) we know 
that they were early Greeks (i.e. Indo-Europeans). But the 
Linear B tablets contain only routine administrative notes, 
the dated information about their large-scale activities is 
purely archaeological. They were quite rich already in the 
16th century BCE (shaft graves used between 1600-1500 BCE) 
but their palaces were built somewhat later (1450-1350 BCE). 
1500 BCE seems to be acceptable as an "average starting date" 
of the Mycenaean civilization. It is an interesting 
parallelism with the Modern Age that even such early European 
states had an intention to colonise. They occupied Crete 
about 1450 BCE (the Minoan civilization was severely weakened 
by the eruption of the Theran volcano about 1500 BCE), and 
their first colonies on the western coast of Anatolia  
(Miletus, Colophon etc.) appeared approximately in the same 
time (it is possible that  Minoan trading posts - or even 
small colonies - existed on the Anatolian coast before the 
arrival of the Mycenaeans). 

The earliest Neolithic settlements in South-eastern Europe 
appeared about 6500 BCE, but those early farmers probably  
were not Europeans but Middle Eastern migrants from Anatolia. 
There is a theory which claims that  the whole Neolithic 
population of  Europe descended from such Middle Eastern 
migrants (see [6]), but this is a strong claim which got many 
criticism. It is more probable that those migrants appeared 
only in certain areas of Europe (Balkan peninsula, large 
river valleys) but most of the Neolithic farmers of Europe 
were descendants of  the previous Mesolithic population (see 
[7]). An other difficult problem is the origin of the Indo-
Europeans which has great importance because all the "great 
nations" of Europe are of  Indo-European origin. It is again 
a much debated issue (see [7], [8], [9], [10], [11]). If we 
accept that the original homeland of the Indo-Europeans was 
in Southern Russia  then the starting date of the "Indo-
European Neolithic" is approximately 5500 BCE. In this case 
we can make an interesting observation: if  the starting 
dates of the "large historical ages" are listed (5500 BCE, 
1500 BCE, 500 CE, 1500 CE) then it is visible that the 
durations of the ages are halving and the beginning of a "new 
age" can be expected in 2000 CE (certainly not exactly in 
this year but very probably before 2050 CE). It must be noted 
that the validity of this "halving rule" doesn't depend 
really on the assumption of the "Indo-European primacy" 
(after all, Indo-Europeans became Europeans only in Europe, 
when they migrated to the regions of other civilizations 
there they integrated into those other civilizations). If we 
assume that the Medium Age began in 400 CE (this is also a 
reasonable date, the Western Roman Empire was quite in the 
decline at that time, Britannia and most of Gaul were lost 
before 410, Rome was sacked by the Visigoths in 410 etc.) and 
extrapolate backward then we get the following dates: 
beginning of  the Antiquity about 1800 BCE (also a reasonable 
date: the first Minoan palaces were built about  1900 BCE), 
beginning of  the European Neolithic about  6200 BCE (not  
too  far from the generally accepted 6500 BCE). In this case 
the starting point of the "new age" is 2050 CE (a more 
realistic date than the year 2000 CE). 

The Antiquity and the Modern Age can be paralleled in many 
ways, probably the most important parallelisms are the 
following: 

  - European states were very active participants of the 
    "world economy", mass production and long-distance trading 
    were typical 
  - the European great powers made big colonisation efforts, 
    in the second half of each age large colonial empires were 
    created (Roman Empire, British Empire etc.) 
  - near to the end of each age the European great powers 
    became militarily (and economically) weaker while the 
    "third world" powers became relatively stronger (the 
    defeats of the "superpowers" in Vietnam and Afghanistan are 
    very ominous signs) 

In order to avoid misunderstandings the following must be 
noted: the "clash of the civilizations" is a popular theory 
now (see [12]), and it is possible to describe the end of the 
Antiquity as such a clash. But such a description is 
misleading: the decline of the (Antique or Modern) great 
powers is caused mostly by internal problems and the 
"barbarian invasions" (which are the effects of the well 
advanced decline) only deliver the final blow to the 
hopelessly weakened state or empire. 

At least from the viewpoint of economy the Neolithic and the 
Medium Age also can be paralleled: in both ages the economic 
self-sufficiency of small regions was typical and long-
distance trade was a rarity. One may say that the volume of 
the long-distance trade between Europe and the other parts of 
the world was increasing during the Medium Age. This is 
probably true but it doesn't contradict with the decline 
between the Late Antiquity and the Early Medium Age. If we 
compare the tables of large cities in [3] then we can see 
that in 361 CE there were four cities in Europe with more 
than 50000 inhabitants (their total population was 570000) 
but in 622 CE there was only one city in Europe with more 
than 50000 inhabitants (Constantinople with 350000 
inhabitants). This indicates a serious decline because the 
persons involved in mass production and long-distance trade 
are usually city-dwellers. Therefore we may infer that the 
coming "new age" of the European civilization will be 
somewhat similar to the Medium Age (i.e. it can be named as 
"New Medium Age"). It is a surprising prediction: the 
"globalization of the world" is a seemingly unstoppable 
process now but the discussion above indicates that the next 
250 years will be the age of  "localization" (at least in the 
areas belonging to the European civilization). But the 
serious problems caused by the current globalization process 
are well visible even today (see e.g. [13]) and it is quite 
possible that  those problems will become fatal within some 
decades. 

There is an other argument which is rather  hypothetical but 
also indicates the necessity of this "New Medium Age". One of 
the greatest achievements of the medieval Europeans is the 
Medieval Technical Revolution which provided (among other 
things) the tools necessary for  world-wide colonisation 
(ocean-worthy ships, advanced navigational techniques etc.).  
If there will  be another colonising age (from 2300 CE?) then 
the most important targets of colonisation will be celestial 
bodies (the Moon, asteroids etc.). This assumption is 
hypothetical but not unrealistic (Man landed on the Moon 
thirty years ago!). It is a common belief  that we cannot go 
to the celestial bodies now because our space transportation 
technologies are too expensive. There is some truth in it, 
but the real problem is not this. The real problem occurs 
when the astronauts arrive to somewhere: they cannot do 
anything there except quickly returning home before their 
reserves are running out. This is a straight consequence of 
our modern industrial technologies: everything is produced in 
large quantities, in large factories containing many highly 
specialised machines, utilising the best raw materials (no 
matter if those must be delivered from thousands of 
kilometres). On a celestial body one cannot have such an 
enormous equipment  and the only available raw materials are 
just  "ordinary stones".  A radical change in our terrestrial  
technologies is necessary in order to produce industrial 
quality products in small quantities with (relatively) small 
equipment from low quality raw materials. In the modern 
globalized world economy such a change is impossible, but in 
a "localized" world where industrially advanced groups may 
find themselves isolated in an adverse environment (desert, 
tundra etc.) in a  not too large territory then there will be 
a very strong incentive to develop such technologies (not 
only for industrial but for agricultural production, too).   

Historians sometimes use the terms "Antiquity" and "Medium 
Age" in case of the non-European civilizations, too, but 
there are no such generally agreed delimiting dates like in 
the European case. The beginning of the Neolithic is well 
defined: appearance of the first farmers / herders, although 
in practice it is difficult to find the remnants of the 
"firsts" and the cultural (ethnic?) classification of the 
finds also can be difficult (there were migrations in the 
Neolithic, too). It is generally agreed that the Antiquity 
begins with the appearance of relatively large states. In 
case of the Middle Eastern civilization the Neolithic began 
about 9500 BCE (first herders in northern Iraq, see [14]), 
but according to [15], if the function of some Epi-
Paleolithic tools is interpreted properly then there was 
agriculture in the Middle East before 10000 BCE. In Egypt the 
first large state was the Old Kingdom which was formed about 
2800 BCE. The unification of Upper and Lower Egypt happened a 
bit earlier but because of the general uncertainties in the 
Middle Eastern chronologies (see [16]) it is better to accept 
this date. In Mesopotamia the first certainly existing large 
state was the Akkadian Empire which was created about 2300 
BCE. In earlier times Sumerian city-states sometimes 
conquered other cities and created small empires, but the 
extent of these empires is very unsure, therefore it is 
better to consider the Akkadian empire as the first. As an 
"average" date for the beginning of the Antiquity in the 
Middle East, 2600 BCE seems to be acceptable. 

In the history of the Middle East there is only one more 
event which is generally accepted as a major turning point: 
the appearance of the Islam. The "Hegira" happened in 622 CE, 
but the real force of the new faith manifested itself during 
the rule of  the "elected Caliphs" (632-661) and the Omayyads 
(661-750) when the Arabic armies conquered almost the whole 
Middle East and some European territories, too. Therefore the 
"third Middle Eastern age" began approximately in 700 CE. To 
call it  "Medium Age" would be quite misleading. City life 
and long-distance trade flourished under the Arabic (and 
other Islamic) Empires, and what is even more important, it 
can be said that the Arabs were the first real Middle Eastern 
colonisers. All the previous Middle Eastern empires were 
rather unifiers than colonisers because they didn't conquer 
territories outside the Middle East. There are seeming 
counter-examples, the most important ones are the following: 

  - Phoenicians. They founded colonies in the south-western 
Mediterranean (including Sicily and Spain) during the 10th 
- 6th centuries BCE,  in parallel with the Greek 
colonisation of some northern and central Mediterranean 
regions. The original inhabitants of Phoenicia were a 
Semitic people (Canaanites) but during the invasions of the 
"Sea Peoples" (Europeans, probably Greeks) in the 12th 
century BCE the region changed significantly. On the coast 
of Palestine (next to Phoenicia) a large group of the Sea 
Peoples settled down (the Philistines). It is very probable 
that other "Sea People" groups were received into the 
Phoenician cities where they mixed with the original 
population. It is certain that advanced maritime 
technologies appeared in Phoenicia after these invasions. 
Therefore the Phoenician sub-civilization cannot be 
considered as a purely Middle Eastern one, it had a 
significant "European inheritance", too. 

  - Persians (the Achaemenid empire, 553-330 BCE). They 
conquered almost the whole Middle East, but they didn't 
conquer territories outside it and probably didn't want to. 
The famous Greco-Persian wars can be interpreted as 
punitive actions triggered by a revolt of the Greek cities 
on the Anatolian coast. The Indus valley also belonged to 
the Persian empire but it is questionable whether that 
region is really an "ancient homeland" of the Indian 
civilization (see below).  

If we accept the above described periodization of the Middle 
Eastern history (the third age could be named as the "Age of 
Expansion") then the starting dates of the ages are the 
following: 9500 BCE, 2600 BCE, 700 CE. We can see that the 
duration of the Antiquity is roughly half of the Neolithic 
therefore it is probable that we have a "halving rule" here, 
too. In this case the end of the "Age of Expansion" can be 
expected about 2350 CE. The prediction which follows from 
this is that the history of the Middle East in the next three 
centuries will be rather similar to the previous 1300 years: 
sometimes a large empire is created, this empire  makes some  
colonisation efforts and after several centuries it  
disintegrates.   

The Indian subcontinent can be divided into three large 
regions: the Indus valley, the Ganges valley and the southern 
region. The development of these regions was rather 
asynchronous, especially in the prehistory. Neolithic 
villages appeared in the Indus valley very early (between 
7000-6000 BCE) while in the other regions the Neolithic began 
only after 5000 BCE. The domesticated plants and animals 
(wheat, sheep etc.) used by the early farmers in the Indus 
valley were of Middle Eastern origin. In the same region 
appeared the first urban culture  of the subcontinent, the 
Harappan sub-civilization, which existed approximately from 
2500 BCE to 1800 BCE. Before discovering the early Neolithic 
villages of the Indus valley, archaeologists thought that the 
Harappan sub-civilization was created by migrants from the 
Middle East. Nowadays this sub-civilization is usually 
considered as the result of the internal development of the 
indigenous Neolithic population, but it is still possible 
that the previous theory was correct. In some Neolithic 
villages of the Indus valley a "destruction layer" was found 
which can be dated about 2500 BCE, this could be the result 
of an invasion (of the founders of the Harappan sub-
civilization). 

In the ancient history of India there is only one more major 
turning point: the creation of the Maurya empire (about 300 
BCE) because this was the first really large state which 
united almost the whole subcontinent. If we consider the 
ancient Indus valley as an integral part of the Indian 
civilization then we get the following starting dates of the 
great historical ages: 7000 BCE, 2500 BCE, 300 BCE. Here we 
can see again a "halving rule": the duration of the second 
age is roughly the half of the first age. Using this rule we 
can extrapolate the sequence of the starting points, the 
following elements are: 800 CE, 1350 CE, ..., 1900 CE (end 
point). This is very unconvincing: these dates are not 
especially significant in the history of India and this 
history certainly didn't end in 1900. But there is an other 
possibility: the Indus valley may not belong to the Indian 
civilization. If we want to draw  now  the dividing line 
between the Middle Eastern and the Indian civilizations then 
we should choose the India-Pakistan borderline. This border 
is not a knew phenomenon: a similar border existed between 
the Indus valley and the rest of the subcontinent many times 
(during the existence of the Harappan sub-civilization, the 
Achaemenid Empire, the Kushan Empire, the Abbasids, the 
Ghaznevids etc.). If we ignore the Indus valley then we have 
only two significant dates in the Indian history: 5000 BCE 
(beginning of the Neolithic), 300 BCE (creation of the Maurya 
empire). If we suppose that the general development of the 
Indian civilization will be similar to the development of the 
Middle Eastern civilization then we may expect the beginning 
of the "Indian Age of Expansion" about 2050 CE. But this date 
might be too early: if we assume that the Indo-Europeans 
("Aryans") had the most significant role in the development 
of the Indian civilization then we must put back the 
beginning of the Neolithic to 5500 BCE, in this case the 
"Indian Age of Expansion" will begin about 2300 CE. 

In the case of the East Asian civilization the most important 
country belonging to it is China. In China the Neolithic 
began about 9500 BCE (see [17]). The first large Chinese 
state was the Shang Empire which was founded about 1500 BCE 
(the extent - in time and territory - of the previous Hsia 
empire is very unsure). In the history of ancient China there 
are no more similarly significant dates. Since the end of the 
Shang empire just disintegration and integration phases 
follow each other although rather unevenly. If we assume that 
the East Asian civilization follows the long-term development 
pattern of the Middle Eastern civilization then we may expect 
the beginning of the "East Asian Age of Expansion" in 2500 
CE. This is a rather far date but the starting dates used in 
this calculation are not very certain and the previous 
assumption also may prove false. But it is certain that China 
was not a colonising force throughout it's history. Just two 
examples: 

  - China never colonised Siberia (in spite of it's 
closeness) 

  - when the expeditions organised by Cheng Ho (in the first 
half of the 15th century CE) created the possibility of 
China becoming the greatest naval and trading power of the 
Indian Ocean then the Ming emperors refused this and 
introduced a strict isolationist policy 

Japan is seemingly a counter-example, at least it's very 
active role in the 20th century may suggest this. But Japan 
didn't intend to colonise territories belonging to the 
European civilization, it's clashes with the European great 
powers followed from the fact that those great powers had 
colonised Asian territories (Manchuria, Philippines, 
Singapore etc.).  

In the case of the Black African civilization the earliest 
Neolithic villages and the earliest states appeared in the 
Nile valley, not too far from Egypt. But this is obviously a 
product of the strong influence of the nearby Middle Eastern 
civilization centre, not of an indigenous development. It is 
better to examine West and South Africa. The earliest 
neolithic (agricultural) sites in the southern part of West 
Africa are dated about 4500 BCE, but pastoralism in the 
western Sahara (much more humid in the Neolithic than now) 
began earlier (about 6000 BCE, cattle domestication). The 
earliest states in West and South Africa (Ghana, Zimbabwe?) 
appeared about 600 CE. If we assume that the long-term 
development of the African civilization follows the pattern 
of the Middle Eastern civilization then the starting dates of 
the "African Ages" are the followings: 6000 BCE, 600 CE, 3900 
CE, i.e. an "African Age of Expansion" can be expected only 
in the very far future. 

In the case of the Central Asian nomad civilization the 
Neolithic began with the domestication of the horse. This 
happened about 5500 BCE in the southern steppe of Eastern 
Europe, but it reached Mongolia at a much later time, 
probably about 3000 BCE.  As we have already seen,  the Asian 
nomads were the most  important  constituents of this 
civilization (at least in historical times). The existence of 
the first large Hsiung-nu state (tribal alliance?) was noted 
by Chinese chroniclers about 200 BCE. The aggressivity of 
these early nomad states didn't mean that they were 
colonisers: they just wanted to collect tributes or sometimes 
just wanted to enforce the continuation of an advantageous 
trade. If a sedentary state met them with force then they 
tried to crush it but when they succeeded they didn't take 
over the administration of the area (see [18]). This method 
was changed only when Genghis Khan created his great empire 
(about 1200 CE) with a sedentary capital (Karakorum) and with 
an administrative organisation. From this point the Mongols 
were able to take over the government of sedentary states (or 
creating their own sedentary states) but in this way they 
lost their nomadic advantages and sooner or later their 
dynasties (or even their states) disappeared. In this case 
the starting dates of the great ages of this civilization are 
the followings: 3000 BCE, 200 BCE, 1200 CE. In spite of the 
significant differences between the Middle Eastern and the 
Central Asian civilizations the names used in the case of the 
Middle Eastern civilization (Neolithic, Antiquity, "Age of 
Expansion") fit well in this case, too. The extrapolation of  
this sequence yields 1900 CE as the next significant date. 
The Central Asian nomads did nothing important at that time 
(they were too few and too weak already) but exactly this 
shows what is this last age: the "Age of Final Decline" which 
will lead to their disappearance. The observed parallelism of 
the Middle Eastern and the Central Asian civilizations might 
suggest that the next great "Middle Eastern Age" will be an  
"Age of Final Decline", too. But it is not certain: the 
differences are also plentiful, the next great "Middle 
Eastern Age" can be quite different (e.g. one may imagine a 
true  "Middle Eastern Medium Age").

4.  Medium-term processes 

Here again better to begin with the European civilization. It 
is a well known feature of Europe's Modern Age history that 
there is a roughly hundred years cycle of  "world wars" 
(great power wars involving the majority of the European 
great powers). This was already known in the 19th century 
(see [1]) but there was no general agreement about which are 
those "world wars" exactly and this cycle was (seemingly) not 
connected with other historical phenomenons therefore it was 
considered as a hypothesis only. The theory was obviously 
successful (the W.W.I came exactly as one could expect and 
even the W.W.II was not contradicting with it - from a 
greater perspective now we know that  "W.W.II was only the 
last battle of W.W.I"). In spite of it, only in the last two 
decades was this theory inspected detailedly. The most 
important results are the following: 

  - The data necessary to describe every war in comparable 
terms was identified (severity, extent etc.) and collected 
about each war of the European Modern Age (see [19]). 

  - The data about the strengths of the great navies was 
collected (see [20], [21]) and it was recognised that the 
relative capability of these navies shows a concentration / 
deconcentration pattern (sometimes one great power owns 
more than 50% of the total naval capability of the great 
powers). 

  - It was shown that throughout the whole Modern Age there 
are long economic cycles (the Kondratieff cycles, named 
after N. Kondratieff, who firstly identified such cycles 
but only in a shorter historical interval) with a roughly 
50 years period, each period consisting of an "upswing" and 
a "downswing" phase. It was shown that the severity of the 
"great power wars" (number of battle fatalities in a given 
interval) strongly correlates with these economic cycles 
(see [22]). 

These results are summarised in Table 2.

-------------------------------------------------------------------

In spite of all these results, the most basic question (is 
there a cycle of great European wars with the period of 100 
years?) is still unanswered. Some authors think that the 
cycle of the "world wars" has the period of 150 years. They 
argue (see [22]) that the three highest peaks in the war 
severity data (in [19]) occur at the Thirty Years War (1618-
48), at the Napoleonic Wars (1803-15) and at the W.W.II 
(1939-45). This agrees well with the traditional historical 
narratives: these wars (and the concluding peace agreements) 
are usually considered as major turning points of  European 
history. Others argue that the history of the Modern Age 
should be considered as a succession of  "hegemonic powers", 
see [23]. These hegemonic powers are those states which 
obtain a more than 50% share of the total naval capability 
(see [20] and  Table 2). It is usually assumed that these 
naval capability concentrations are the results of great 
power wars, i.e. the most important great power wars are 
those which precede the occurrence of these concentrations 
(see [21]). This is a rather problematic logic, e.g. 
according to this concept the Thirty Years War was not an 
important war. In recent studies (see [24]) it was shown that 
these hegemons are primarily  "trading hegemons", not  
"military hegemons". According to this new concept, in the 
downswing phase of every Kondratieff cycle certain 
innovations (organisational, commercial, technical etc.) 
appear. The future hegemon pioneers the utilisation of these 
innovations and obtains a large share in the world trade 
during the next upswing phase. This large trade makes 
possible (and worthwhile) to create a large merchant fleet 
and (in order to protect it) a large navy (in the 16th-17th 
centuries these were the same, almost every large ship was a 
battleship and a merchantman simultaneously). This causal 
chain agrees well with the historical narratives. It is also 
characteristic that the "hegemons" are not the main 
participants of the great wars but as "lucky outsiders"  they 
can increase their wealth enormously during the wars by 
selling war materials (i.e. their economic advantages are 
increased but not created by the great wars). 

This  "hegemonic" description resembles somewhat to that 
description of Antique history in which the history of the 
Mediterranean is discussed as a succession of thalassocracies 
(Minoans, Mycenaeans, Phoenicians, Greeks, Carthaginians, 
Romans, Byzantines). This is a much criticised concept (see 
[25]) but in spite of these criticisms it is popular since 
the Antiquity. It is an interesting analogy that the first 
thalassocracies / hegemons (Minoans, Portugal etc.) are 
rather small and weak (a typical counter-argument in the 
mentioned criticisms) but their successors are gradually 
stronger and at the end real "superpowers" (Roman Empire, 
British Empire) appear. The author thinks that the best way 
to explain the war severity data distribution listed in Table 
2 is to assume the existence of two factors. The first factor 
is economic (as it is discussed detailedly in [22]) and 
increases the severity of the great power wars in the upswing 
phases of the Kondratieff cycles. The second factor is not 
yet identified but it is well synchronised with the calendar 
centuries. It increases the severities of the great  power 
wars in the first half of every century and decreases the 
severities in the second halves of the centuries. The 
intensity of this "second factor" is gradually increasing, it 
was quite ineffective in the 16th century but very effective 
in the 20th century (this is well visible in Table 2). This 
"second factor" might be  connected to the "hegemonic cycle" 
but  the causal link is not obvious. 

Using this model one may expect the outbreak of the next  
"world war" of European history near to end of the next 
Kondratieff upswing phase, approximately between 2015 and 
2025. Right now this looks like a rather improbable 
prediction because now there is only one superpower, any 
attack against it seems to be hopeless. But we must take into 
consideration the followings, too: 

  - a sudden collapse of the USA (similar to the collapse of 
the Soviet Union) is very improbable, but it's relative 
strength is gradually declining  

  - two previous world wars were preceded by a "sudden rise" 
of the attacking great power (France from 1792 to 1802 and 
Germany from 1920 to 1940) 

As it was mentioned, there is no generally agreed answer to 
the question "which were the most important great power wars 
of the Modern Age?". But most authors agree that the last 
three "world wars" were the followings: 

  - War of the Spanish Succession and the (second) Great 
    Northern War (1701-14, 1700-21) 
  - Napoleonic Wars (1803-15) 
  - W.W.I and W.W.II (1914-18, 1939-45) 

The Great Northern War is usually left out but in fact it was 
an "auxiliary war" of the Spanish Succession (somewhat 
similarly to the W.W.II when the "German" and "Japanese" wars 
went on rather independently). After the peace of Utrecht, 
some belligerents (Prussia, Denmark etc.) of the latter war 
joined the former one to increase their territorial gains. 
There is a common feature of  these "world wars": a large 
invading army entered Russia and after a long forward push it 
was crushed by the Russians. These catastrophes were decisive 
events, therefore we may expect that Russia will be an 
important participant of the next world war, too. This 
indicates that in the beginning of the 21st century the 
"suddenly rising great power" will be Russia. This is again a 
surprising prediction but the followings also show that it is 
a probable development: 

  - such a sudden rise is not unprecedented in Russian 
history (compare the status of the Soviet Union in 1922 and 
in 1945) 

  - Russia still has many  key features necessary for a 
superpower (large territory, large population, large 
industrial base with high-tech capabilities etc.) 

  - Russia still owns and maintains the nuclear arsenal 
inherited from the Soviet times, the build-up of a 
comparable arsenal by any other great power in the next 20 
years is very improbable 

The great military successes in the previous world wars 
probably created the impression in many Russian strategists 
that they are invincible in a  defensive  war. This is not 
necessarily true, in earlier times there was at least one 
important counter-example: the successes of the Mongol 
armies. If a modern military genius could combine the 
firepower and short-distance speed of the modern armies with 
the mobility and self-sufficiency (!) of the nomad armies 
then he could win even against Russia. But such a development 
is very improbable in the near future therefore Russian 
leaders might be tempted quite easily into a war: they might 
not win it but certainly will not suffer an annihilating 
defeat. The real danger comes not from this but from the 
opposite possibility: if an advancing Russian army reaches 
the borders of a "nuclear power" (this can be even Pakistan!) 
then that power might decide to use it's nuclear weapons and 
from this point the war might escalate very quickly into a 
total nuclear exchange involving all the "nuclear powers" and 
their allies, too. 

Therefore the occurrence of  the next world war in the 
predicted interval would be a great success of social theory 
but also the greatest catastrophe of mankind, we must try to 
prevent it. Typical suggestions (see [24], [26]) about this 
prevention advise to increase the importance and power 
(including military power) of the various international 
organisations, especially the UN. This should lead to the 
formation of a "world state" which controls most of the 
nuclear weapons (i.e. has it's own army) and which is 
governed democratically by some top-level council of the UN 
(probably not the present Security Council  which is 
frequently paralysed by the vetoes). Unfortunately the 
formation of such a world state in the near future is 
certainly impossible, a modern nation-state (with the 
"sovereignty" among it's most cherished values) will not 
subjugate it's military forces (especially if they have 
nuclear weapons) to any international organisation. But there 
is an other possibility: from the analysis of the long-term 
processes of European history we know that the "New Medium 
Age" will start soon and the various European states / 
regions will be rather isolated and self-sufficient in that 
age. If the great powers could create such a "localized" 
world by their own will then there won't be next world war. 
Such actions would be quite consistent with the usual great 
power politics: isolationism has a long tradition in many 
countries and it is the hidden (or not-so-hidden) dream of 
many great statesmen to create a strong, well-protected 
empire with their country in the centre of it. There's only 
one thing which may go wrong: if the great powers cannot 
agree about their "spheres of influence" (or don't respect 
the agreed borders) then great wars may occur. It means that 
the borders of each sphere of influence must be drawn 
reasonably (coinciding with geographic, ethnic etc. barriers, 
possibly leaving out the "problematic zones", creating "easy 
to defend - difficult to attack" borderlines) and the 
contacts across these borders must be minimized. 

In the case of the non-European civilizations there is no 
such commonly known "historical pattern" like the periodical 
world wars of the European history but there is one common 
feature in every great civilization: the rise and fall of the 
empires. According to A. Toynbee before the final decline of 
any civilization a "universal empire" is created which lasts 
for approximately 400 years. According to the concept 
presented here, the "final decline" of most civilizations 
will happen only in the far future (if it will happen at all) 
but it is quite possible that the "typical" lifetimes of the 
great empires fall into the 300...500 years interval. An 
extensive analysis about the spatial and temporal extent of 
the great empires is presented in [27], [28], [29], [30]. In 
these studies no such "typical lifetime" was found, but the 
"duration time" as it is defined in [30] (duration at more 
than one half of the polity's stable maximum size) is a 
rather mechanistic concept. Probably it is better to analyse 
the "most important" cases individually. In [27] a list of 
the 20 largest empires / states is presented, the followings: 

1. British Empire. 
The first British colonial cities were founded in North 
America about 1600 CE,  the British East India Company was 
founded in the same time (the first British trading posts 
appeared soon after it in India). India and Pakistan became 
independent in 1947, Canada and Australia are practically 
independent since the first decades of the 20th century. In a 
strict sense the lifetime of the British Empire was 
approximately 340 years. But one may say that  "an empire is 
not really fallen until at least one significant successor 
state of it exists". The large overseas English-speaking 
countries (USA, Canada, Australia) certainly can be regarded 
as successors, i.e. in this sense the British Empire still 
exists  and it's lifetime will be certainly more than 400 
years. 

2. Mongol Empire. 
It was created by Genghis Khan between 1206 and 1223 CE 
(unification of Mongolia, conquest of  northern China and the 
western parts of Central Asia). His successors continued the 
conquests (China, southern Russia, Iran, Mesopotamia) but the 
unity of the empire was rather illusory because it was 
partitioned between the sons of  Genghis after his death 
(1227). In a strict sense the empire's lifetime was only 20 
years. But the successor states continued to exist with 
Mongol rulers. The most significant successor states were the 
followings: 
  - The Yuan dynasty in China, ended in 1368. 
  - The state of the Il-Khans in Persia, fragmented and 
    reunited several times, final break-up about 1460. 
  - The Golden Horde, it was conquered by Timur about 1390, 
    after his death three successor states were formed on it's 
    territory: the Khanates of Crimea, Kazan and Astrakhan. The 
    latter two were destroyed by Russian attacks about 1550. 
Therefore one may say that the lifetime of the Mongol Empire 
(in a broad sense) was 340 years.  

3. Russian Empire. 
The first major Russian state, the Kievan Rus was a 
significant power in the 9th - 11th centuries CE, but it 
disintegrated in the 12th century, the remnants of it (small, 
weak states) were an easy prey to the conquering Mongols. The 
rulers of the conquered states were mostly Russians, but they 
were vassals of the Golden Horde. The rise of Moscow started 
with Ivan I (1325-41, victories over the neighbouring small 
Russian states). Under the rule of Ivan III (1462-1505) 
Moscow conquered almost all of the smaller Russian states and 
formally disengaged itself from the successors of the Golden 
Horde. His successor (Ivan IV, 1533-84) conquered the 
Khanates of Astrakhan and Kazan. The approximate starting 
date of the empire can be 1500 CE. The events of the Great 
Russian Revolution can be interpreted in two ways: the old 
empire was terminated and a new empire was founded (in this 
case the old empire's lifetime was 410 years) or the 
existence of the same empire continued with new rulers. In 
the latter case the empire's lifetime will be more than 500 
years because the events of the last decade, although 
weakened the empire, certainly cannot be interpreted as 
"total disintegration". 

4. French Empire. 
The colonisation of Canada started in the middle of the 16th 
century CE, the last significant French colony (Algeria) 
became independent in 1962. From these dates one may infer 
that the lifetime of the empire was at least 360 years but it 
would be misleading. During this time France lost all of it's 
colonies three times (at the end of the Seven Years War in 
1763, after the selling of Louisiana in 1803, and at the end 
of the Napoleonic Wars in 1815). It is also characteristic 
that the end of the French colonial rule was not followed by 
the formation of large French-speaking successor states (with 
the possible exception of Quebec, but that is not an 
independent state). Therefore it is better to leave this 
empire out of consideration.  

5. Manchu Empire. 
Manchuria was united about 1600 CE, Korea was conquered in 
1637. Under the rule of the last Ming emperor, China 
disintegrated (peasant revolts). Taking advantage of the 
opportunity, the Manchus conquered China (between 1644 and 
1660) and founded their dynasty. The starting date of the 
empire is approximately 1650 CE. In the second half of the 
19th century the ossified empire gradually disintegrated 
(military victories of the Europeans, territorial losses, 
internal revolts like the Taiping rebellion and the Boxer 
rising). In 1911 the Revolution of the Young Chinese began, 
the last emperor abdicated in 1912, the territory of China 
became politically fragmented. The revolutionary era ended 
with the victory of the Communist Party in 1950, the Chinese 
territories (with minor exceptions) were re-united, but the 
neighbouring countries which were conquered in the Manchu era 
remained independent (except Tibet). In the strict sense the 
empire's lifetime was 250 years but if we consider the PRC as 
a successor of the Manchu empire then the lifetime will be 
longer than 350 years. 

6. Spanish Empire. 
The conquest of America began in 1492, the great native 
empires (Mexican, Peruvian, Colombian) were destroyed before 
1540. The starting date of the empire can be 1530 CE. The 
Latin American successor states gained their independence in 
the 1820s. The Philippines and the Spanish Sahara were lost 
much later but these were rather insignificant colonies. 
Therefore in a strict sense the empire's lifetime was 300 
years. But large Spanish-speaking successor states (Mexico, 
Argentina etc.) still exist, in a broader sense the lifetime 
will be more than 500 years. 

7. Baghdad Caliphate. 
The greatest conquests happened under the rule of the elected 
Caliphs (632-661) and under the Omayyads (661-750). The 
starting date of the empire can be 650 CE. Under the rule of 
the Abbasids (750-1258) the empire gradually disintegrated 
(the Omayyads in Spain declared their independence in 756, 
northern Iran and the north-western parts of Africa became 
independent about 800 etc.). The year 940 CE is usually 
considered as the ending date of the Baghdad Caliphate 
because political changes in the 930s rendered the Caliph 
powerless. In the strict sense the empire's lifetime was 290 
years. But significant successor states (above all, the 
Fatimids in Egypt) continued to exist under Arabic rule until 
the middle of the 12th century, therefore in a broader sense 
the empire's lifetime was 500 years. 

8. Yuan Empire. 
It was a successor state of the Mongol empire, see at 2. 

9. Canada. 
It is a successor state of the British empire, see at 1. 

10. PRC (People's Republic of China). 
It might be regarded as a successor state of the Manchu 
empire, see at 5. 

11. USA. 
It is a successor state of the British empire, see at 1. 

12. Hsiung-nu Empire. 
The extent of this empire (in time and territory) is not 
known very well. It existed probably from 230 BCE and started 
to disintegrate about 50 BCE, but two successor states were 
formed on it's territory, the Eastern and Western Hun states, 
which existed approximately between 10 CE and 90 CE. In a 
strict sense the empire's lifetime was 180 years, but if we 
take into consideration the successor states, too, then it  
was 310 years. 

13. Brazil. 
It is a successor state of the Portuguese colonial empire. 
The first Portuguese posts on the coasts of South America and 
South-west and South-east Africa were created in the 16th 
century, but major colonisation efforts in South America 
(e.g. expelling the Dutch and French rivals from the 
territory) began only after Portugal regained it's 
independence in 1640 CE. Brazil became independent in 1822. 
In a strict sense we can say only that it's lifetime will be 
more than 180 years, but if we consider the whole Portuguese 
empire than it's lifetime is already more than 360 years. The 
last Portuguese colonies in Africa became independent in the 
1970s, the lifetime of the Portuguese empire (in the strict 
sense) was 330 years. 

14. Australia. 
It is a successor state of the British empire, see at 1. 

15. Han Empire. 
This was the succession of three empires: the Ch'in (221-206 
BCE), the Western Han (206 BCE - 9 CE) and the Eastern Han 
(25-250 CE). Their total lifetime was approximately 470 
years. Before the Ch'in empire, China was quite disintegrated 
("epoch of the warring states", 403-221 BCE). After the end 
of the Eastern Han empire the "period of the three kingdoms" 
followed (220-265 CE) but after this period China was again 
united (Chin empire, 266-317 CE). Near to  the end of  this 
empire  serious and long-lasting fragmentation occurred. 
Therefore the lifetime of the Han empire in a broad sense was 
520 years. 

16. Ming Empire. 
The empire of the Ming dynasty lasted from 1368 to 1644 CE. 
It was preceded and followed by dynasties of  non-Chinese 
(Mongol, Manchu) rulers, but the territorial integrity of 
China was not affected seriously at the beginning and at the 
end of it. It's lifetime was approximately 280 years, but if 
we consider the empires of the Yuan, Ming and Manchu 
dynasties as "different governments of the same state" then 
we get a very long lifetime, 630 years. 

17. Gok (Kok) Turk Empire. 
It was a nomad empire, it's extent in space and time is not 
known very well. It existed probably from 550 CE to 650 CE 
but it is also probable that a successor state of it 
("Western Turk Empire") existed until 750 CE. Therefore the 
lifetime of this empire was between 100 and 200 years. 

18. Golden Horde. 
It was a successor state of the Mongol empire, see at 2. 

19. Achaemenid Empire. 
It had a predecessor state, Media, which became a great power 
under the rule of Cyaxares (625-585 BCE). The Persians were 
vassals of the Medes, but under the rule of Cyrus II (559-529 
BCE) they conquered Media, Lydia, Babylonia and eastern Iran. 
The starting date of the empire can be 610 BCE (if Media is 
included) or 540 BCE. The Achaemenid Empire was conquered by 
Alexander between 334 and 330 BCE, but it continued to exist 
(under Greek rulers) with the same organisation. After the 
death of Alexander his successors fought  the "Wars of the 
Diadochi" (323-281 BCE). At the end of these wars Seleucus 
gained the control of Syria, Mesopotamia and Persia. His 
successors ruled here until 139 BCE when the Parthians 
conquered most of this territory (a Seleucid state existed in 
Syria until 64 BCE, but that was not a significant power). In 
the strict sense the Achaemenid Empire's lifetime was 210 
years, but in a broader sense it was 470 years. 

20. Tang Empire. 
It had a predecessor empire: China was united by the emperor 
Yang Chien (founder of the Sui dynasty) about 590 CE. His 
successor was dethroned by domestic rebels whose leader (Li 
Yuan, 618-626 CE) founded the Tang dynasty. Between 755 and 
765 the empire was weakened by a serious internal revolt, the 
unity was restored but since that time the government 
gradually weakened and rebellions became more and more 
frequent. The last Tang emperor abdicated in 907, after it 
the empire quickly disintegrated. The empire's lifetime was 
290 years in the strict sense, 320 years in a broader sense. 

Now it is possible to make a small statistics of empire 
lifetimes in a "strict sense" (predecessor and successor 
states are ignored, i.e. from the above list the no. 8, 9, 
11, 14, 18 are left out) and in a "broad sense" (predecessor 
and successor states are considered as "integral parts" of 
the empires). In both cases it is better to leave out the 
French empire (no. 4) and the early nomad empires (no. 12, 
17). In the "broad sense" case it is logical to consider the 
Yuan, Ming and Manchu empires as a single empire and to leave 
out the PRC (a "too young" successor or new empire). In the 
"strict sense" case it is better to consider the whole 
Portuguese empire (as no. 13) instead of Brazil (it is only a 
successor state and it became independent not too long ago). 

In the "strict sense" case there are 1 lifetime less than 100 
years, 6 lifetimes between 200 and 300 years, 4 lifetimes 
between 300 and 500 years. In the "broad sense" case there 
are 6 lifetimes between 300 and 500 years and 4 lifetimes 
longer than 500 years. Therefore one may say that even in a 
strict sense the "expectable lifetime" of a great empire is 
approximately 250 years, while in a broad sense the 
"expectable lifetime" is 400...500 years. Using these 
lifetimes  it is possible to examine the great powers (or 
major regional powers) which exist now and to determine 
(approximately) their future lifetimes.  

In the case of the European civilization the Russian empire 
is the only large empire of the Modern Age which still 
exists. The events of the previous decade (fall of the 
communist system, return to a political system which 
resembles to the system of the Provisional Government in 
1917) has shown that modern Russia is rather a continuation 
of the tsarist Russia, not a "new start". In this case the 
empire is quite old (almost 500 years), one may expect it's 
fall in the "not too far" future (before 2050?). Even the 
successor states of it probably will not have long lifetimes, 
500 years is a long lifetime even in the "broad sense". This 
doesn't exclude the "quick rise" mentioned at the beginning 
of this section, seeing the symptoms of the decline Russian 
rulers probably will resort to traditional methods (creating 
a police state with a strong army, trying to increase 
nationalist sentiments, in a desperate situation they may 
even start a war). The British empire had fallen already, but 
it has left several great successor states, the greatest is 
the USA. The USA is really a superpower now, but if we 
consider it as an "independent empire" then it is almost 250 
years old, one may expect the "final decline" of it in the 
not too far future. If we consider it as a successor state of 
the British empire then we cannot expect a much longer 
lifetime because this empire (in the "broad sense") is 
already 400 years old. The Spanish empire (also in the "broad 
sense") is even older, therefore the Spanish successor states 
probably will not reach the level of  the great powers in the 
"not too far" future. But Brazil is different: as an 
"independent empire" it is only 180 years old, and even the 
Portuguese empire (in the "broad sense") is not too old (360 
years). It is quite possible that in the second half of the 
21st century Brazil will be a real great power. It's 
political and geographic position also indicates this: it has 
no close military ties with the present great powers, it is 
far from the probable conflict zones, i.e. in the next world 
war (if there will be such a war) it has a good chance to be 
a "lucky outsider". Such  lucky outsiders  (if they had the 
necessary resources) frequently became major powers after the 
previous (European) world wars. 

On the territories of the Middle Eastern civilization there 
are no great powers now. The latest Middle Eastern great 
power, the Ottoman empire fell at the end of  W.W.I. Modern 
Turkey was created on it's ruins almost immediately and the 
successes of this new state (repelling the invaders from  the 
Turkish territories, staying out of W.W.II etc.) may suggest 
that the foundations of a new empire has been laid and the 
expansion of this new empire may start soon (e.g. when the 
European great powers will be weakened). But the modern 
Turkish state is based on European principles (European-style 
political system, separation of the state and the church 
etc.) while the Turkish society is still an Islamic society. 
This contradiction is a grave internal problem of Turkey and 
it will not disappear quickly. Therefore it is probable that 
Turkey will not be strong enough in the near (and medium-
term) future to start a major expansion. 

Modern Iran is seemingly a counter-example, the political and 
religious systems of the country co-operate well (some 
Europeans view the resulting "Islamic state" with disgust, 
but it could be a successful state in spite of this view). 
But if we examine the antecedent states then we can see that 
the Iranian states in the 20th century are the successors of 
the Kajar dynasty (1794-1925). Iran (in the "broad sense") is 
still in the declining phase of this dynastic empire, the 
formation of a new empire there in the near future is rather 
improbable. In Mesopotamia there were no strong states after 
the fall of the Baghdad Caliphate, therefore the  formation 
of a great empire in this territory is not probable in the 
near (or medium-term) future. In Egypt, the modern republic 
was created by a nationalist revolution in 1952-53. It had a 
significant antecedent state, the empire of  Mohammed Ali 
(1805-49), but that was only a short-lived empire (it had 
lost most of it's conquests after the Turkish-Egyptian war in 
1839-40). The  Republic of Egypt  fared well in the 20th 
century (victories against the Israelis and Europeans), it is 
not impossible that it will begin to expand in the 21st 
century. 

The PRC is probably not the continuation of the Manchu empire 
but a "new start" (there was a significant gap between the 
end of the old and the beginning of the new empire, and the 
communist system did not fall in China - the Chinese leaders 
probably adopted it well to the structures of the Chinese 
society). If it avoids the possible clashes with the European 
great powers (especially during the next world war, if there 
will be such a war) then it may exist for 200...300 years and 
even it may expand a bit, mainly in South-east Asia (the 
formation of a great power in that area is very improbable). 
The perspectives of Japan are not so bright: modern Japan was 
created in the Meiji era (1868-1912), as an empire it is 
almost 150 years old, it will preserve (probably) it's 
integrity in the 21st century but any expansion is very 
improbable. It's strong military ties with the USA are also 
unfortunate, serious involvement in a great war can be fatal. 

Modern India was formed in the 1940s, it had no significant 
antecedents (there were no strong independent states on the 
subcontinent  in the 18th and 19th centuries). The Republic 
of India seems to be a rather cohesive state, it has a good 
chance to exist in another 150...200 years, although a major 
expansion is not very probable (see the analysis in the 3. 
section). The same analysis indicates that the appearance of  
Black African great powers in the near (or medium-term) 
future is very improbable (a strong but slowly evolving 
civilization). 


5.  Short-term processes 

Here again the best choice is to begin with the European 
civilization.  The most salient repetitive events of European 
history in the second half of the 20th century CE are the 
crises of the East-central European countries (1956: violent 
revolt and Soviet intervention in Hungary, 1968: non-violent 
revolt and Warsaw Pact intervention in Czechoslovakia, 1981: 
non-violent revolt and coup d'etat in Poland, 1991-95: 
civil/secession war in Yugoslavia). One may think that these 
crises were only the manifestations of the "general crisis of 
communism", but this interpretation is wrong. The most 
serious event (the Yugoslavian war) occurred after the fall 
of (European) communism, and Yugoslavia was the "least 
communist" and most independent among the East-central 
European countries. If we try to extrapolate backward the 
above sequence then we get the following dates: 1944, 1932, 
1920, 1908. In fact, there were serious crises in the region 
at these dates (or near to these): 1944 - Warsaw uprising, 
1934 - coup d'etats in Bulgaria, Estonia and Latvia, 1919 - 
Roumanian-Hungarian war. The Balkan wars (1912-13) were 
somewhat "out of phase" but this fact points to the real 
cause of the crises: the East-central European region (in 
it's modern form) was created after the W.W.I rather 
unnaturally (ethnic boundaries were not respected), the 
region is plagued with ethnic problems since then. Naturally 
these problems manifest themselves regularly in the form of 
violent crises. We may expect the following crisis in the 
2004-8 interval (taking 1956 as the "base year" and assuming
a 12...13 years cycle length). 

The exact nature of this coming crisis is not yet obvious. 
Right now (in the year 2000) it would be very easy to point to 
Kosovo and to predict an Albanian-Yugoslavian war, but easy 
solutions are not always the right solutions. E.g. in an 
early description of this theory the author predicted that 
the crisis in the early 1990s will occur in Roumania (see 
[31]). This was not a bad guess (the fall of the Roumanian 
dictatorship at the end of 1989 was a violent event), but now 
we know that the real crisis of the decade was the 
Yugoslavian war.  

The severity of an ethnic crisis is probably proportional 
with the size of the ethnic minority involved. There is a 
very large (over 2 millions) Hungarian minority in Roumania, 
the outbreak of a serious conflict  is rather probable, 
although not necessarily in the near future. If Kosovo will 
secede from Yugoslavia then the Hungarians will be the last 
significant minority in Serbia, this also may cause a 
conflict.  The largest ethnic minority in the region since 
the fall of the Soviet Union is the Russian one. Their 
presence in Belarus and in the Ukraine is not very disturbing 
(these peoples are culturally similar to the Russians) but in 
the Baltic states they are frequently treated as undesirable 
aliens. A crisis involving a Russian minority group (if it 
occurs in the right time, i.e. between 2015 and 2025) can 
provide the perfect ignition mechanism for the next world war 
(except if the other great powers will respect the limits of 
the "Russian sphere of influence", but  now  there are no 
such generally agreed limits). It must be noted here that in 
the earlier centuries of the Modern Age East-central Europe 
was rather an "average" region, the really dangerous conflict  
zones were the divided countries of  Western and Southern 
Europe (the Netherlands, Germany, Italy). If the great powers 
could agree on the limits of their  "spheres of influence" in 
the region (like in the 19th century, just better respecting 
the major cultural/ethnic borderlines) then the 
"dangerousness" of East-central Europe would decrease 
significantly.  

In the political science the conflict zones similar to East-
central Europe are described usually as "shatterbelts" (see 
[32], [33]). According to [33] in the second half of the 20th 
century the shatterbelts are the following: Middle East, East 
Asia, South-east Asia, South Asia, Sub-Saharan Africa, Middle 
America (i.e. Central America and the Caribbean islands). In 
[33] East-central Europe is not considered as a shatterbelt 
because the Russian occupation of the region putatively 
stabilised it. As we have seen, even this occupation didn't 
eliminate the conflicts, only dampened them. Now when the 
region is "free" again we have good reasons to consider it as 
a shatterbelt (there is serious internal instability and 
great power rivalry in it). The previous list contains only 
the "great shatterbelts", there are some zones which could be 
described as "small shatterbelts" (e.g. Northern Ireland) but 
because of their relative unimportance, these are usually 
ignored. The above list is over-generalising, too, because in 
most cases not the mentioned (sometimes very big) geographic 
regions are the shatterbelts, only some smaller subregions. 
If we restrict the analysis to the second half of the 20th 
century then those sub-regions are the followings: 

1. Middle East. 
Typical conflict zones are the major cultural division lines 
(Arab-Israeli, Arab-Black African, Armenian-Azeri, Russian-
Muslim, Greek-Turkish) and the countries burdened with 
internal ethnic hostilities (Israel, Lebanon, Afghanistan). 
The problem of the largest ethnic minority in the region (the 
Kurds) didn't lead to a major conflict to date, but it is 
possible that in the future they will get the support of a 
great power and in this case a severe regional war may break 
out. The "unification crises" (Morocco - Spanish Sahara, Iraq 
- Kuwait) are also typical in the region. The cultural 
differences between the neighbouring Arab countries are 
marginal, many borders were drawn rather arbitrarily in the 
colonial era. 

2. East Asia. 
This shatterbelt was very active in the first half of the 
20th century, large areas of  China were occupied by colonial 
forces who warred with each other and with the Chinese 
liberation movements. There is a major cultural division line 
(Russian - Chinese) in the region, but this didn't lead to 
really serious conflicts in the second half of the 20th 
century. But there are still two divided countries 
(China/Taiwan, North/South Korea), the problem of Korea 
caused a major war in 1950-53. 

3. South-east Asia. 
Since the end of the last colonial wars (French and US 
Vietnam wars, 1946-55, 1965-75) the conflicts in the region 
seem to be easing. China also reduced it's activity there 
(abandoned the attacks against Vietnam and the support of the 
anti-Vietnamese forces in Cambodia). There are some major 
cultural division lines in the region between the Muslims and 
the Buddhists and the Christians, but these caused only minor 
conflicts in the second half of the 20th century (with the 
possible exception of Eastern Timor). Now there are no grave 
ethnic conflicts in the region  but there are substantial 
Chinese minorities in some countries of  South-east Asia. 

4. South Asia. 
There are two major cultural division lines in the region, 
the India-Pakistan and the India-China border zones. Violent 
conflicts occurred at both borders in the second half of the 
20th century. India and Pakistan are both multi-ethnic 
countries but they seem to be quite cohesive (their prolonged 
strife probably helps to dampen the internal problems, the 
secession of Bangladesh was caused rather by geographic than 
ethnic reasons). The Tamil-Singhalese conflict in Ceylon 
caused violent uprisings several times. 

5. Sub-Saharan Africa. 
In spite of the vastness of this area the whole region can be 
considered as a single large conflict zone. The colonial era 
has left rather arbitrarily drawn borders, almost every 
country has a multi-ethnic composition (endless possibilities 
of  "secession" and "unification" wars and intra-country 
conflicts). The Black African societies are in an early phase 
of the development, there are many  tribes instead of a few 
large nations, this also aggravates the problems. There is a 
major cultural division line (Arab - Black African) in the 
region, but this caused only moderately serious conflicts to 
date (mostly in Sudan and Chad).  

6.  Middle America. 
There are no significant cultural differences between the 
Spanish-speaking Latin American countries and their borders 
were created rather arbitrarily, it is easy to find there a 
pretext for a "secession" or a "unification" war. Such wars 
really occurred in the region (e.g. the Salvador-Honduras 
conflict  between 1969 and 1992) but the typical Latin 
American crises are  internal political conflicts (uprisings, 
coup d'etats etc.). An important cause of these conflicts is 
the poverty (democracy is not working well in poor countries 
frequently, revolutionary propaganda can be very effective if 
there are large, very poor social classes etc.). But there is 
a cultural reason, too: Latin American leaders tend to 
consider the USA as a model (and the US foreign policy just 
reinforces it), but Catholic countries seem to be not very 
fit for democratic government. Even in Europe, where the 
countries had a much longer time to evolve politically, long-
lasting and stable democratic governments in Catholic states 
are rare. This cultural problem certainly will not disappear 
soon. 

After surveying the shatterbelts, it is possible to examine 
the question whether there are such periodical crises in the 
other shatterbelts like in the East-central European one. The 
answer is not easy, the crises are so numerous in these 
regions that almost arbitrary "crisis series" can be created. 
But the following examples (in which the elements of the 
series are somewhat similar events) probably indicate that 
such cycles exist: 

  - Arab-Israeli wars: 1948, 1956, 1967, 1973, 1982, 1991 (in 
the latter war Israel participated only passively, but this 
happened only because of the very active presence of the 
USA) 

  - Chad:  1965-67 (anti-government revolts), 1971 (strikes, 
government crisis), 1975 (coup d'etat), 1980-81 (civil war, 
Libyan intervention), 1986 (civil war, driving out the 
Libyans), 1990 (coup d'etat) 

  - Vietnam:  1945 (beginning of the anti-colonial 
revolution), 1954-55 (battle of Dien Bien Phu, independence 
of Vietnam, secession of South Vietnam), 1964-65 (US 
bombing of North Vietnam began, US expedition force arrived 
to South Vietnam), 1975 (victory of the communist forces, 
unification of Vietnam) 

  - Middle America:  1948-51 (civil war in Costa Rica, 
revolution in Panama), 1959-62 (revolution in Cuba, US-
supported counter-revolutionary attacks, civil war in 
Dominica), 1969 ("soccer war" of Honduras and Salvador), 
1978-80 (revolution in Nicaragua, civil war in Salvador), 
1988-91 (coup d'etats in Haiti, US intervention in Panama) 

The above lists only indicate the probability of the 
hypothesis of  "periodical crises", certainly don't prove it. 
But if the predicted crisis in the 2004-8 interval will occur 
in East-central Europe then at least in this region the 
hypothesis can be considered as proven.
