Bangladesh, officially the People's Republic of Bangladesh, is a country in South Asia. It is bordered by India on all sides, Burma (Myanmar) on the southeast and the Bay of Bengal to its south. Together with the Indian state of West Bengal, it makes up the ethno-linguistic region of Bengal. The name Bangladesh means 'Country of Bengal' in the official Bengali language. The present-day borders of the country were established during the demise of the British Indian Empire in 1947, when Bengal was partitioned and the region became East Pakistan, part of the newly formed nation of Pakistan. However, it was separated from West Pakistan by nearly 1,500 km (about 900 mi) of Indian territory.
