Dehradun NEPAL once upon a time ------------ Gorkhas and British Period ------------- For about two decades till 1815 it was under the occupation of Nepal. In April 1815 Gorkhas were ousted from Garhwal region and Garhwal was annexed by the British. In that year the area now comprising the tehsil of Dehra Dun was added to the 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 has been administered as separate district. In 1968 the district was taken out from the Meerut Division and included in the Garhwal Division. Following a war between the Nepal and the British, the Treaty of Sugauli was signed in 1816 that established the current boundaries of Nepal. Garhwal and Kumaon regions, including Dehradun were ceded to the British. While territories west of the Alaknanda were returned to the Garhwal Raja now established at Tehri, Eastern Garhwal (later British Garhwal) and Dehradun were retained under direct British control. During British rule, Dehradun used to be the summer base for the Viceroy's bodyguards. The British established: The Forest Research Institute in 1906; The Royal Indian Military College (Rashtriya Indian Military College) in 1922; and The Indian Military Academy in 1932 http://en.wikipedia.org/wiki/Dehradun
