Jang Bahadur Kunwar, who later became the first Prime Minister of Nepal, orchestrated a brutal massacre involving around 40 members of the palace court. This event unfolded against a backdrop of intense power struggles within the Shah dynasty, where factions vied for dominance. The fallout stemmed from longstanding rivalries and conspiracies that characterized the political arena of Nepal during this period. By eliminating his rivals, Jang Bahadur aimed to solidify his position and influence over the monarchy and governance of the state.

The massacre was not just a pivotal moment for Jang Bahadur but also reflected the larger context of instability within Nepalese politics. It was carried out in the Royal Palace in Kathmandu, with the execution reflecting both personal vendettas and broader political machinations. This drastic act showcased the lengths to which Jang Bahadur was willing to go to secure his power, ultimately resulting in his appointment as prime minister. Following this event, he implemented significant reforms and established a more centralized administrative structure.

The massacre marked the beginning of a new era in Nepal, where the exercise of power became increasingly ruthless. The political landscape transformed as Jang Bahadur and his Rana lineage asserted control, setting the stage for a dynasty that would dominate Nepalese politics for over a century. The implications of this power grab resonated throughout the country, influencing subsequent governance and social hierarchies.
