The Patkum zamindari estate was initially part of the extensive Ramgarh district until the late 18th century. Subsequently, it became a part of the Birbhum district until 1805 when it was integrated into the Jungle Mahals. Later, it transitioned to Panchet and then to the Manbhum district of British India. After India gained independence, the region came under the jurisdiction of Bihar province. However, due to the 1953 State Reorganization, the Patkum territory underwent a partition, with some areas being allocated to Bihar (present-day Jharkhand) and others to West Bengal states.
