Jungle Mahals

Jungle Mahals, literally 'jungle estates', was a district formed by British possessions and some independent chiefdoms lying between Birbhum, Bankura, Midnapore and the hilly country of Chota Nagpur in what is now the Indian state of West Bengal. The district was located in the area known as the Jungle Terry, a thickly forested region inhabited by tribal groups such as the Santhal people Bhumij
History.
The vagueness of the jurisdiction caused inconvenience. In 1805, Regulation XVIII was passed whereby the areas known as Jungle Mahals was separated from the jurisdiction of the Magistrates of the districts of Burdwan, Birbhum, Bankura and Midnapore and placed under a Magistrate of Jungle Mahals. The district thus formed was composed of 23 parganas and mahals.
By Regulation XIII of 1833, the district of Jungle Mahals was broken up. The estates of Senpahari, Shergarh and Bishnupur were transferred to Burdwan District and the remainder constituted the Manbhum District.
