The Kot Event
During the rule of Mathbar Singh, power lay in the hands of Queen Rajya Laxmi, the sovereign Rajendra Bikram, the heir apparent Surendra, and Mathbar Singh himself, but there was no co-ordination of authority. After the assassination of Mathbar Singh, the administration was entrusted to four generals, Gagan Singh, Abhiman Singh, Fatte Jung and Jung Bahadur Rana. This didn't please the Queen. So, she tried to gain full power with the help of Gagan Singh. This was suspected by the King. So Gagan Singh ws murdered at the secret order of the King while he was in prayer room. Mad with fury, her royal sould thirsting for revenge, she turned to Jung Bahadur for help. The wily general seized the opportunity to get rid of all future opposition. The queen was asked to convene an assembly of all the nobles at Kot to enquire into the crime (assassination of Gagan Singh) and punish the culprits. Meanwhile, Jung Bahadur brought 3 platoons of armed forces and made them stay surrounding the Kot. On September, 1846 AD, ie. 1st Ashwin 1903 at the call of the Queen, almost all the courtiers came to the fort unarmed at midnight. A dispute arose and a refusal on the part of one of the councillor to carry out the order of the Queen resulted in what is called the Kot Massacre. During the Event, Jung Bahadur massacred 32 persons of the nobility, 26 persons fled and 19 persons were driven away. After "Kot Parba" Jung Bahadur became the despotic ruler.

The Bhandarkhal Event
After assassinating his rivals in the kot Event, Jung Bahadur became the PM and Commander-in-Chief of the Nepalese Army. Now Queen Rajya Laxmi wanted to make a tool of JUng Bahadur, to get rid of the Crown Prince Surendra and place her son Ranendra on the trhone. But jUng Bahadur flatly refused to carry out her order, so she secretly hatched a plot to take the life of Jung Bahadur. Kazi Birdhoj Basnyat and some of the courtiers conspired to kill Jung Bahadur, on the insistence of the Queen. But Bijaya Raj, who was included as one of the conspirators by Kazi Birdhoj, who was a close friend of Jung Bahadur, disclosed the plot to Jung Bahadur.
As a result, Birdhoj and other conspirators were all put to death. The event, which took place in November, 1846 AD is known as the Bhandarkhal Event, as the conspirators were all found lying in ambush at Bhandarkhal to assassinate Jung Bahadur.

The Alou Event
After the Bhandarkhal Event, Jung Bahadur accused the Queen of misuse of power and hatching a plot to assassinate the PM and the Crown Prince. He passed a resolution at a meeting of courtiers, which the King and Crown Prince also attended. The Queen was held responsible for the Kot Massacre as wel. The resolution deprived her of her power and sentenced her to exile. The Queen desire to go to Kahsi with her tow sons, Ranendra and Birendra. The King also accompanied her, authorizing Surendra to rule on his behalf.
With the consent of the courtiers, Jung Bahadur placed Surendra on the throne in 1904 BS. When King Rajenra heard this in Kashi he became furious with rage, With the help of Guru Prasad Shah, pandit Ranga Nath and others, he collected some soldiers, occupied Barewa and came up to Alou. The Nepalese troops sent from Kathmandu under the command of Sanak Singh made a surprise attack on the soldiers of King Rajendra at Alou. This event is known as Alou Event in which King Rajendra Bikram was made prisoner and was brought to Kathmandu. Thus, all attempts to bring down Jung Bahadur failed and he continued to become a despotic ruler for some time to come.
