Limbuwan–Gorkha War

The Limbuwan–Gorkha War was a series of battles fought between the king of Gorkha and the rulers of various principalities of Limbuwan from 1771 to 1774 AD. After the conquest of Majh Kirat (Khambuwan kingdoms) and Wallo Kirat by the Gorkhas, they invaded Limbuwan on two fronts. One front was in Chainpur (present-day Sankhuwasabha District) and the second front was in Bijaypur (present-day Dharan, Sunsari District). Bijaypur was the capital of the Morang Kingdom of Limbuwan Yakthung Laje.

The war came to an end in 1774 AD with the ceasefire treaty, "Treaty of Salt and Water" between the Yakthung Laje Limbuwan kings and the Gorkha king. It recognized co-existence of government system and equal rights between the Gorkha king and the Yakthung Laje Limbuwan kings. The war was ended with the signing of the Limbuan–Gorkha treaty which ceded much of the territory east of the Arun River to the Gorkha kingdom.
