Bengal ( /baŋla/ or Bônggo /bɔŋɡo/) is a geographical and ethno-linguistic region in the eastern part of the Indian subcontinent, at the apex of the Bay of Bengal and dominated by the fertile Ganges delta. The Bengal region was politically divided in the 1947 Partition of India based on religion: predominantly Hindu West Bengal became a province (now a state) of India, while predominantly Muslim East Bengal became a province of Pakistan and later gained independence as Bangladesh. Some regions of the historical kingdoms of Bengal are now part of Nepal and the neighbouring Indian states of Assam, Tripura, Bihar, Meghalaya, Manipur, Jharkhand, and Odisha. The Bengali people ( Bangali), who speak the Bengali language ( Bangla), which is Indo-Aryan, natively inhabit the region, alongside dozens of indigenous ethnic groups who speak minority languages of the Tibeto-Burman, Austroasiatic, and Dravidian families.
