After the great Sepoy Mutiny in 1857, the British government assumed direct control of the administration of India, including along with the Chittagong Hill Tracts, which was not yet formally separated from Chittagong, from the East India Company. The territorial jurisdiction of the Chakma Raja, however, was fixed by a proclamation dated 6th Shraavana 1170M.S (1763 CE) by the company as "All the hills from the Feni River to the Sangoo and from Nizampur Road in Chittagong to the hills of Kooki Raja".
