These nobles were given the title of 'Zamindar' (Land owners). The Kothari family reigned over Sagardighi from the time of Mir Qasim until the abolishment of the Zamindari system after the independence of India. The last ruling Zamindar of Sagardighi and the surrounding areas of Ratanpur was Bimal Singh Kothari. His family/descendants continue to live in Calcutta (now Kolkata).

 Sagardighi CD block lies in the Rarh region in Murshidabad district. The Bhagirathi River splits the district into two natural physiographic regions – Rarh on the west and Bagri on the east. The Rarh region is undulating and contains mostly clay and lateritic clay based soil. As the Rajmahal hills slopes gently down from adjoining Jharkhand it forms the Nabagram plain at the lowest edge of its elevation in this region. The eastern slope of the region is characterised by the existence of numerous cliffs and bluffs.

 The Rarh region or the western part of the district is drained by the right bank tributaries of the Bhagirathi, flowing down from the hilly / plateau region of Santhal Pargana division in neighbouring Jharkhand. The Farakka Barrage regulates the flow of water into the Bhagirathi through the feeder canal. Thereafter, it is fed with the discharge from the Mayurakshi system. About 1,800 km2 of area in the neighbourhood of Kandi town is flooded by the combined discharge of the Mayurakshi, Dwarka, Brahmani, Gambhira, Kopai and Bakreshwar – the main contributor being the Mayurakshi. Certain other areas in the western sector also get flooded.
