The Treaty of Sugauli (additionally spelled Sugowlee, Sagauli and Segqulee), the settlement that set up the limit line of Nepal, was marked on 2 December 1815 and confirmed by 4 March 1816 between the East India Company and King of Nepal taking after the Anglo-Nepalese War of 1814-16. The signatory for Nepal was Raj Guru Gajraj Mishra helped by Chandra Sekher Upadhayaya,the signatory for the Company was Lieutenant Colonel Paris Bradshaw. The settlement called for regional concessions in which parts of Nepal would be given to British India, the foundation of a British agent in Kathmandu, and permitted Britain to enlist Gurkhas for military administration. Nepal likewise lost the privilege to convey any American or European representative in its administration (prior a few French authorities had been sent to prepare the Nepali armed force).

Under the arrangement, around 33% of Nepalese-controlled region was lost including every one of the domains that the King of Nepal had won in wars in the most recent 25 years or so, for example, Sikkim in the east, Kumaon Kingdom and Garhwal Kingdom (otherwise called Gadhwal) in the west and a great part of the Teraiin the south. A portion of the Terai terrains were reestablished to Nepal in 1816. More Terai terrains were reestablished to Nepal in 1860 to say thanks to Nepal for helping the British to stifle the Indian insubordination of 1857
