After the cession of the Diwani to the East India Company in 1765, Birbhum was administered from Murshidabad until 1787. In that year in consequence of the unsettled state of the country, which required a separate administration, it was constituted as district with Vishnupur ( i.e. eastern portion of Bankura), and this arrangement continued till 1793, when Vishnupur was transferred to the Burdwan Collectorate. In 1809, the collectorship of Birbhum was abolished, and the district was again administered from Murshidabad, an Assistant Collector remaining in charge at Suri. In 1820, Birbhum was reconstituted as a separate district and restored to its former area, with the exception of a few estates were transferred to the Jungle Mahals. After the Santhal rebellion, the upland tracts on the West, which had been a rallying point of the rebels, were transferred to the newly constituted district of Santhal Paraganas and in this way four paraganas and a part of the fifth were detached from Birbhum, viz., Sarath Deoghar, Pabbia , Kundahit Karaya, Muhmmadabad and part of Darin Mauleswar. In 1872 the district consisted of the following thanas (1) Suri, (2) Rajnagar, (3) Dubrajpur, (4) Kasba (now Bolpur), (5) Sakulipur, (6) Labpur, (7)Barwan, (8) Mayureswar with a total area of 1,344 square miles.
