Dehradun is the capital of The Indian state of Uttarakhand, and has a rich and eventful history, it also finds mention in scriptures as well. During the British Raj, the town was known as Dera Dun.
Dehradun itself derives its name from the historical fact that Baba Ram Rai, the eldest son of the Seventh Sikh Guru Har Rai, set up his “Dera” (camp) in “dun” (valley) in 1676. This ‘Dera Dun’ later on became Dehradun. The Mughal Emperor Aurangzeb was highly impressed by the miraculous powers of charismatic Ram Rai.
