The first Parva – Kot Parva is the massacre that happened in Kot of Kathmandu. During the event, Jung Bahadur Rana killed a lot of his opponents including the reigning prime minister. After the event, he was appointed the new prime minister of Nepal.
A junior-queen of King Rajendra was planning to remove the crown-prince Surendra and make her own son Ranendra Shah the king of Nepal. For that, she had previously sought help from the prime ministers. They refused to kill the crown prince. She was hoping Jung Bahadur to help her in her mission. But, when Jung Bahadur refused, she plotted to kill Jung Bahadur. Jung Bahadur had his spies in the palace who informed him about the party at Bhandarkhal where he was to be given a poisoned food. An army was also awaiting for him there to make sure he didn’t escape.
But, Jung Bahadur countered the plot by killing all those who were conspiring against him. Although some escaped, he killed most of his opponents in the second Parva – Bhandarkhal Parva.
