India Company then merged Kumaon, Dehradun and east Garhwal into the British Empire while west Garhwal was given back to Sudarshan Shah, then becoming known as Tehri Riyasat. Garhwal Kingdom Tehri Garhwal or the Garhwal Kingdom, was a princely state, ruled by the Rajput Parmar (Shah) dynasty. Later, it became a part of the Punjab Hill States Agency of British India, which consists of the present day Tehri Garhwal District and most of the Uttarkashi district. In 1901, it had an area of about and a population of 268,885. The ruler was given the title of raja, but after 1913, he was honoured with the title of Maharaja. The ruler was entitled to salutes of 11 guns and had a privy purse of rupees 300,000. 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 over the region. Consequently, the 60th king of Panwar Vansh, Manabendra Shah, accepted the sovereignty of the Indian government. Thus, in August 1949, Tehri Riyasat was merged into Uttar Pradesh and was given the status of a new district, the Tehri Garhwal district. Subsequently, on 24 February 1960, the state government separated its one tehsil which was given the status of a separate district named Uttarkashi. The former royal palace of the Maharaja of Tehri Garhwal at Narendra Nagar, now houses the Ananda In the Himalayas spa, established 2000. Modern developments In the 1960s, Tehri Garhwal extended much farther east than it currently does. In 1997, much of the eastern portion of Tehri Garhwal was detached and merged with portions of the Pauri Garhwal district and the Chamoli district to form the Rudraprayag district.
