The Anglo-Nepalese War (1814–16), also known as the Gurkha War, was fought between the Kingdom of Nepal (present-day Nepal) and the East India Company as a result of border disputes and ambitious expansionism of both the belligerent parties. The war ended with the signing of the Treaty of Sugauli in 1816, which ceded around a third of Nepal's territory to the British. The British were the invading forces, while the Nepalese maintained a defensive position. The British attacked in two successive waves of invasion. It was the most expensive war waged during the governorship of Lord Moira.
