If we go according to Skanda Purana, Dun was formed from a part of the region called Kedar Khand. History says that it was included in the kingdom of Ashoka by the end of the 3rd century B.C. For centuries the region formed a part of the Garhwal kingdom. For about two decades till 1815 it was under the rule of the Gorkhas. In April 1815 Gorkhas were moved out from Garhwal region and Garhwal was annexed by the British. In that year the area which now have tehsil Dehra Dun was added to district Saharanpur. In 1825, however, it was transferred to the Kumaon Division.
