The subdivision of Banki comprising the feudatory state of Banki and zamindari of Dampada was added to the district in 1840 after the Raja was deposed for murder. The district reached its greatest extent after 1948 when the princely states of Narasinghpur, Baramba, Athagad and Tigiria were added to the district post their accession to India. Subdivisions like Gram Panchayats and Community Developments blocks were introduced in 1962. A small portion of the district adjoining Bhubaneswar was transferred to Puri district that year.
