Bengal /bɛŋˈɡɔːl/ (Bengali: বাংলা  Bangla  or বঙ্গ Bongo/Bônggô) is a geographical and ethno-linguistic region in South Asia. It lies in the north-eastern region at the apex of the Bay of Bengal and is dominated by the fertile Ganges delta. The region was politically divided in the 1947 Partition of Bengal based on religion: predominantly Hindu West Bengal became a province (now a state) of India, and predominantly Muslim East Bengal (now Bangladesh) became a province of East Pakistan. Some regions of the historical kingdoms of Bengal are now part of the neighbouring Indian states of Assam, Tripura, Bihar, Jharkhand, and Odisha.
