Bangladesh, officially the People’s Republic of Bangladesh, is a country in South Asia. It is bordered by India on three sides and Myanmar to the southeast; the Bay of Bengal forms the southern coastline. Together with the Indian state of West Bengal, it comprises the ethno-linguistic region of Bengal. The name Bangladesh means “Country of Bengal” and is written in Bengali as বাংলাদেশ and pronounced [ˈbaŋlad̪eʃ]. The exact origin of the word Bangla or Bengal is unknown.
The population of Bangladesh ranks seventh in the world, but its area of approximately 144,000 km2 is ranked ninety-third. It is the third largest Muslim-majority nation, but has a slightly smaller Muslim population than the Muslim minority in India. It is also one of the most densely populated countries in the world. Geographically dominated by the fertile Ganges-Brahmaputra Delta, the country has annual monsoon floods, and cyclones are frequent. Bangladesh is one of the founding members of South Asian Association for Regional Cooperation (SAARC), BIMSTEC, and a member of the OIC and the D-8.
The borders of Bangladesh were set by the Partition of India in 1947, when it became the eastern wing of Pakistan (East Pakistan), separated from the western wing by 1,600 km (1,000 miles). Despite their common religion, the ethnic and linguistic gulf between the two wings was compounded by an apathetic government based in West Pakistan. This resulted in the independence of Bangladesh in 1971 after a bloody war, supported by India. The years following independence have been marked by political turmoil, with thirteen different heads of government, and at least four military coups.
