Datarpur State was founded in the middle of the sixteenth century by Raja Datar Chand, a scion of the princely families of Siba and Guler who named the state after himself. From 1786 the state was a feudatory of Kangra State until Raja Govind Chand made an alliance with the Gurkha invaders from Nepal in 1806, securing his complete independence. Govind Chand was succeeded by his son Jagat Chand when Datarpur was conquered by Ranjit Singh of Lahore in 1818 and annexed to the Sikh Empire of Pañjab (Punjab), although a jagir was granted to Jagat Chand as compensation. But in 1848 Jagat Chand joined a rebellion against the British and was deposed, dispossessed and exiled to Almora. The territory of Datarpur was added to Siba State and annexed by the British Raj in 1849 as Dada-Siba. The descendants of Jagat Chand were given no jagir, but the royal house still exists.
