Established The vagueness of the jurisdiction caused inconvenience. In 1805, the new district of Jungle Mahals was created by a regulation (Regulation XVIII of 1805), comprising areas from Birbhum (the 1787 British district incorporating
Bishnupur), Burdwan, and Midnapore, and placed under the jurisdiction of a new Magistrate.
Disestablished By Regulation XIII of 1833, the district of Jungle Mahals was broken up, and a new administrative unit known as the
South-West Frontier Agency was formed. The estates of Senpahari, Shergarh and
Bishnupur were transferred to
Burdwan District and the remainder constituted the
Manbhum District. ==Statehood demand==
