Explanation:

The original seat of the rulers of the erstwhile Bushahr state was at the Kamru Fort, in the village of Kamru at the banks of the Baspa River at Sangla in Kinnaur. The fort is currently abandoned and houses an idol of Kamakhya Devi (Kamakshi Dev), which is believed to have been brought several centuries ago from Kamakhya temple in Guwahati. The rulers subsequently moved to Sarahan. The Palace of the "Raja of Bushahr state" at Sarahan ("The Srikhand view") was built by order of Raja Padam Singh for his lodging in September 1917. The current residence of the "Raja of Bushahr state" is at the Padam Palace at Rampur, Shimla district. The town of Rampur may have been founded by Raja Kehri Singh in the 17th century or by Raja Ram Singh in the 18th. The rulers moved down from their traditional seat in Sarahan to the banks of the river Sutlej. Bushair was one of the richest princely states in the hills and was an important center for trade between Tibet, Kinnaur and the lower areas.

With a personal gun salute of 9 guns, the ruler of Bashahr was the only Hills "Raja" amongst India's upper class of princely salute states, but was not entitled to the style of His Highness until independence in 1947.
