Many
janapadas grew up along the old
Bhagirathi channel from the ancient times till around the 16th century:
Kalighat, Boral,
Rajpur,
Harinavi, Mahinagar,
Baruipur, Baharu,
Jaynagar Majilpur,
Majilpur,
Chhatrabhog etc.
Bipradas Pipilai's
Manasavijaya, composed in 1495, mentions many places in this region. "
Chand Sadagar, a merchant character of the
Manasavijaya, reached Baruipur, from Kalighat, through the old Bhagirathi channel. From there he proceeded towards Chhatrabhog, and then traveling through Hatiagarh pargana reached the open sea".
Chaitanyadeva (1486–1534) also went through this route. Travelling by boat to
Puri he halted at the village of Atisara, near Baruipur. "His last stoppage in
24 Parganas was at Chhatrabhog, now a village within the jurisdiction of the
Mathurapur police station. Chhatrabhog seems to have been an important river-port on the old Bhagirathi channel". Rama Chandra Khan, the
zamindar of Chhatrabhog, helped Chaitanyadeva to continue with his journey. ==Geography==
