About the city
Dehra dun, the capital of Uttrakhand sprawls in the foot hills of Himalayas at the centre of the 120 ks. long Doon valley. The name Dehra dun is literally made up of two words where Dera (camp) and Dun (valley). The beautiful town referred as the ‘gateway' to Mussoorie and Garhwal interior is perhaps one of the oldest cities in India. It was occupied in turns by the sikhs, Mughals and Gurkhas before coming under the reigns of the British. Elite educational and other institutions were established during the British period. Dehra Dun is today proud of its institutions like the Forest Research Institute of Himalayan studies. Survey of India and Botanical survey of India etc. Dehra dun is also famous for aromatic long grain rice basmati and delicious lychees. It was included in the kingdom of Ashoka by the end of the 3rd century BC.It is revealed by history that for centuries the region formed part of the Garhwal kingdom with some interruption from Rohillas. For about two decades till 1815 it was under the occupation of the Gorkhas. In April 1815 Gorkhas were ousted from Garhwal region and Garhwal was annexed by the British. In that year the area now comprising 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.

The district is named after its chief city Dehra Dun. Dehra appears to be a corruption of dera signifying a temporary abode or camp. During the reign of Aurangzeb, Ram Rai, Guru of the Udasi Sikhs on being ordered by the Mughal king to retire to the wilderness of the Dun, had pitched his tents here in what is now the Khurbura locality of the town and has also built a temple near Dhanawala. Around these two sites, grew up the town popularly known as Dehra. The term dun or doon means the low lands at the foot of a mountain range, and as the bulk of the district lies in such a terrain, it justified the dun part of the name.
Another derivation of the term dun is stated to be from Dronashram, hermitage of Guru Dronacharya of Mahabharata fame, who sojourned for a season in the village of Devara, situated near to Dehra to perform his devotions at a lonely spot.
