The three parvas are related to each other as at kot parva, it is said that the queen held an assembly in order to find out the murderer of Gangan Singh, a private person of the Queen. But it went off as a mass killing of the high level courtiers. The next event was thought to be the conspiracy of Queen Rajyalakshmi to kill Jung Bahadur as he was deadly against making her son a king. But Jung Bahadur with the help of his brothers and 6 platoons of soldiers managed to kill all his opponents in the Bhandarkhal garden. After this event Rajendra Bikram, son of Queen Rajyalakshmi, was dethroned. Outraged with the development of event, he left Benaras to declare against Jung Bahadur and attacked at Alau near birgunj, which is called Alau event.
In kot parva, Jung Bahadur killed more than 25 officers and exiled about 600 nobles from the country. The prominent among them were Bir Kishore Pandey, General Abhiman Singh, Chautaraia Fathe Jung and Dal banyan Pandey. Thus, Jung Bahadur removed all his powerful opponents in one stroke. The massacre cause instant rise of Jung Bhadur. The queen granted him prime minstership and post of commander-in-chief in the night of 15 sept 1486 AD. The next was carried out at Bhandarkhal gardern of the Basntapur palace in 1903 BS, which was known as Bhandarkhal parva. Jung Bhadur banished the queen to Kashi in the charge of her involvement in hatching a plot to kill him. King also accompanied her and in the Alau parva, Jung Bahadur's army attacked the army of King Rajendra. Rajendra Bikram Shah was brought to Kathmandu and imprisoned in Bhaktapur palace. When people tried to rescue him, he was shifted to Hanuman Dhoka.
Jung Bahadur was the grandson of Ranjit Kunwar and son of Kaji Balnarsingh Kunwar. He was bobrn on 18th June, 1817 AD at Borlang, Gorkha. He was very clever. He strove much and became a strong personality of palace on 23rd Kartik, 1903 BS in Kot massacre. Jung Bahadur finished all his post then he became prime minster and commander-in-chief. Bhandarkhal parva helped to finish live opponents. In alau incident, he jailed King Rajendra also. In this way, he established Rana rule which lasted for 104 years in Nepal i.e. 1846-1951 AD.
Anarchy was set to the country, leading no stable government or prime minister. The senior queen Samragya Laxmi supported the pandey's and exercised supreme authority. She involved about 100 villagers in Ramnagar ignoring the warning of Hogdson, the Britist resident in Nepal. So the relationship with the British, a greatest imperialism was worsening. Meanwhile Samragya Laxmi died in 1841 which made the junior Queen Rajyalaxmi more powerful. Making king the puppet, she became a defector ruler. She was interested to make her own son Rajendra, the legitimate heir. So she called Mathabar Singh Thapa from Simla. But he didn't fulfill her desire so she encouraged murdering Mathabar Singh Thapa. The queen wanted to reward the post to Gangan Singh Khawas, who had illicit affairs with her. Though, Chautaria Jung Shah was made the prime minister, Gagan Singh was more powerful. Being in doubt King encouraged to murder him. Due to such foreign relationship inconsistency in government and prime ministers, sefish steps of queen and frequent internal conflict, the country was in trouble. Therefore, the rise of Jung Bahadur Rana was a need of time.
