It is the least populous Division within the entirety of Bangladesh. It is bounded by Dhaka Division on the north, the Bay of Bengal on the south, Chittagong Division on the east and Khulna Division on the west. The administrative capital, Barisal city, lies in the Padma River delta on an offshoot of the Arial Khan River. Barisal division is criss-crossed by numerous rivers that earned it the nickname Dhan-Nodi-Khal, Ei tin-e Borishal (rice, river and canal built Barishal). History Early Middle Ages In early times the Barisal region was composed of an amalgamation of marshlands formed by the merging of islands brought into existence and built up by alluvial soils washed down the great channels of the combined Brahmaputra-Ganges-Meghna river systems. In the early 13th century, Muhammad bin Bakhtiyar Khalji led the Muslim conquest of Barisal, and soon later Muhammad bin Tughluq completely conquered eastern Bengal. The Hindu chieftains from northwest Bengal were dislodged from power and they dispersed over Barisal region and founded the kingdom of Bakla.
