History
Over the 10th-11th centuries A.D., Kinnaur was a part of the Guge kingdom. The Guge kingdom broke apart in the 12th century, and the Bushahr state arose in the Western Himalayas, taking over most parts of present-day Kinnaur. The Bushahr state originated in the Kamru village of Sangla valley. However, the uppermost part of Kinnaur remained under Tibetan influence until the late 17th century, when it was handed over to the Bushahr state by the Tibetans as a reward for assistance in the Tibet-Ladakh-Mughal War. The Bushahr state shifted its capital to Sarahan, and later still to Rampur, which caused this state to be known eventually as 'Rampur-Bushahr'. Rampur-Bushahr was attacked by the Gurkhas in the early 19th century. Soon afterwards, the British gained supremacy in the region. Rampur-Bushahr became a princely state owing suzerainty to the British crown, until India's Independence in 1947. Most of present-day Kinnaur district was known as 'Chini tehsil' under the Rampur-Bushahr state. On 15 April 1948, Rampur-Bushahr became a part of the Republic of India, and a part of an administrative unit called the Mahasu district. In 1960, the Chini tehsil and fourteen villages of the neighbouring Rampur tehsil were separated from the Mahasu district to create the new district of Kinnaur.
