グルカ戦争
Bhimsen's prime ministership is best remembered for the Anglo-Nepalese war. The territorial expanse of the Gurkha empire had reached its greatest extent from Sutlej river in the west to the Teesta river in the east. However, Nepal entered into a disastrous Anglo-Nepalese War with the East India Company lasting from 1814–16, which was concluded with the Treaty of Sugauli, by which Nepal lost almost one-third of its land. He is also remembered for bringing about a large number of social, economic, and administrative reforms, as well as the modernization of Nepalese Army on the template of the French military forces. During his lifetime, he commissioned the building of many temples and monuments such as Dharahara also known as "Bhimsen Stambha" ("Bhimsen Tower").
