The Dehradun district stretches from the Ganges river in the east to the Yamuna river in the west, and from the Terai and Shivaliks in the south and southeast to the Great Himalaya in the northwest. Dehradun is also known as the 'Adobe of Drona'.
Dehradun is located 230 km from the national capital, Delhi. The district headquarters is Dehradun, which has also served as the provisional capital of Uttarakhand since its founding in 2000, and may well become the permanent capital.
Dehradun has always been an important center for Garhwal rulers which was captured by the British. The headquarters of many National Institutes and Organizations like ONGC, Survey Of India, Forest Research Institute (FRI), Indian Institute of Petroleum (IIP) etc are located in this city.
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.
In 1828, Dehra Dun and Jaunsar Bhabar were placed under the charge of a separate Deputy Commissioner and in 1829, the Dehra Dun district was transferred from the Kumaon Division to the Meerut Division. In 1842, Dun was attached to Saharanpur district and placed under an officer subordinate to the Collector of the district but since 1871 it is being administered as separate district. In 1968 the district was taken out from Meerut division and included in the Garhwal Division.
