Explanation:

Kinnaur was a part of erstwhile Chini Tehsil of Mahasu district. It became a separate district on 1 May 1960. Kinnaur was a part of the erstwhile Bushahr principality which had its capital at Kamru. Later, the capital was shifted to Rampur Bushahr. After the fall of the Kannauj Empire the rulers of Kamru annexed adjoining territories by force and laid the foundation of the state of Bushahr, to which the region of Kinnaur belonged till the dissolution of the state after independence of India. In the absence of authentic historical records the early history of the Kinnaur region is obscure and the reference of the Kinnaur or Kannaura and their land is by and large confined to legends and mythological accounts.
