Historically the western frontier of ancient Pundravardhana kingdom, bordering Anga of Mahabharat fame, the Dinajpur area remained somewhat obscure in the major empires that held sway over the region and beyond till the rise of the Dinajpur Raj during the Mughal period. Some areas later forming a part of Uttar Dinajpur were parts of kingdoms in Nepal. Dinajpur district was constituted by the British in 1786, with a portion of the estate of Dinajpur Raj. Subsequent to the Permanent Settlement in 1793, the semi-independent Dinajpur Raj was further broken down and some of its tracts were transferred to the neighbouring British districts of Purnea, Malda, Rajshahi and Bogra. In 1947, the Radcliffe Line placed the Sadar and Thakurgaon subdivisions of Dinajpur district in East Pakistan. The Balurghat subdivision of Dinajpur district was reconstituted as West Dinajpur district in West Bengal. Raiganj subdivision was formed in 1948.
