This war was the most important event during the Mukhtiyari (Mukhtiyarship) of Bhimsen Thapa since it affected every aspect of the later course of Nepalese history. Considering the many successes that the Nepalese army had seen during the expansion campaign of Nepal, Bhimsen Thapa on the Nepalese side was one of the main proponents of the war with the British, which was against the better advice of the likes of Bada Kaji Amar Singh Thapa, who actually did the fighting and knew about the hardships of war.

The war ended with the signing of the Treaty of Sugauli in 1816, which ceded around one-third of Nepal's territory to the British. Furthermore, according to the treaty, Nepal had to allow for the establishment of a permanent British resident in Kathmandu and had to forgo all self-determination in foreign affairs.
