One of the greatest moments of history is that the next hesitant advance of European civilization - the development of the first city-states - took place not on the fertile open central European plains, but in a remote island to the south of the Aegean Sea which was completely lacking in metal resources. While the glittering mounted warrior-princes of central Europe dissipated their creative energy in warefare, a highly cultured yet peaceful society, built on trade and an agricultural surplus, emerged on Crete.
The history of Greece can be traced back to Stone Age hunters. Later came early farmers and thecivilizations of the Minoan and Mycenaean kings. This was followed by a period of wars and invasions, known as the Dark Ages.In about 1100 BC, a people called the Dorians invaded from the north and spread down the west coast. In the period from 500-336 BC Greece was divided into small city states, each of which consisted of a city and its surrounding countryside
The Bronze Age civilization that developed (c. 3000-1200 BC) in the basin of the Aegean Sea, mainly on Crete, the Cyclades, and the mainland of Greece.For some reason the Myceneans abandoned their civilization between 1200 and 1100 BC. The populations of their once-mighty cities dwindled rapidly until there was no urbanized culture left on the Greek mainland. Most of the cities were eventually destroyed, and all the great craftsmen of the Mycenean cities faded away when society could no longer support them.
In the absence of archaeological evidence, it seems unlikely that a nomadic, tribal group could so easily overcome a highly efficient, warfare centered society like the Myceneans.
