From 1787 to 1812, the Gorkhas captured nearly 200 villages which were under the control of the East India Company. The British argued with the king of Nepal but to no avail. Finally, the Gurkha War (Anglo-Nepalese War) began in 1814, when an army of 8,000 under Major General Marley attacked Kathmandu. Four thousand soldiers under Major General Wood started an operation from Gorakhpur and 3,500 soldiers attempted to take over Dehradun under Major General Zileswy, where a Gorkha army of 300–400 was led by Balbhadra Thapa. The Gorkhas fought a fierce battle and crushed the British, who were reinforced by soldiers and cannons. Finally, the British army captured Dehradun on 30 November 1814.
The British Army then moved towards Kumaon. After a fierce battle, the Gorkha commanders Hastidal and Jayrakha were killed at Vinayathal. The war ended with the Sugauli Treaty, signed on 2 December 1815 and ratified on 4 March 1816 by Gorkha supreme commander Bamshah and thus, British rule started in the hills. The East India Company then merged Kumaon, Dehradun and east Garhwal into British Empire while west Garhwal was given to Sudarshan Shah which then became known as Tehri Riyasat.
New capital
King Sudarshan Shah established his capital at Tehri town and afterwards his successors Pratap Shah, Kirti Shah and Narendra Shah established their capital at Pratap Nagar, Kirtinagar and Narendra Nagar, respectively. Their dynasty ruled over this region from 1815 to 1949. During the Quit India Movement people of this region actively worked for the independence of the country. Ultimately, when the country was declared independent in 1947, the inhabitants of Tehri Riyasat (Tehri State) started their movement to free themselves from the clutches of the maharaja.
Due to this movement, the situation became out of his control and it was difficult for him to rule
