Bangladesh ( or ; Bengali: বাংলাদেশ), officially the People's Republic of Bangladesh (গণপ্রজাতন্ত্রী বাংলাদেশ Gônoprojatontri Bangladesh), is a country in South Asia. It is bordered by India and Burma (Myanmar) and faces the Bay of Bengal to its south. Together with the Indian state of West Bengal, it makes up the ethnolinguistic 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 British partition of Bengal in 1947, when 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. Due to political exclusion, ethnic and linguistic discrimination and economic neglect by the politically dominant western wing, popular agitation grew and gave rise to a secular cultural nationalist movement, leading to the declaration of independence and Bangladesh Liberation War in 1971. In the aftermath of war and independence, the new state endured poverty, famine, political turmoil and military coups. The restoration of democracy in 1991 has been followed by relative calm and economic progress.
Bangladesh is a unitary secular parliamentary republic, with an elected parliament called the Jatiyo Sangshad. It is the world's eighth most populous country and has one of the highest population densities in the world. The Bengali people form the vast majority of the population, however Bangladesh is also home to various indigenous peoples in its northern and southeastern districts. The country is identified as a Next Eleven economy. It is a founding member of regional groupings SAARC and BIMSTEC, and is a member of the Commonwealth, the Non-Aligned Movement, the OIC and the Developing 8 Countries.
Geographically, the country straddles the Ganges-Brahmaputra Delta and is subjected to annual floods and cyclones. The country faces a number of major challenges, including poverty, corruption, overpopulation and vulnerability to climate change. However, Bangladesh has been noted for its progress on the Human Development Index. The country has increased life expectancy by 23 years, achieved gender parity in education, reduced population growth and improved maternal and child health.Dhaka and Chittagong, the country's two largest cities, have been the driving force behind much of the recent growth.
