The present-day borders of Bangladesh were established during the partition of the British Indian Empire in 1947, when eastern Bengal became part of the newly formed nation of Pakistan. 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 and civil disobedience led to the Bangladesh Liberation War in 1971. After 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.
Founded as a secular democracy in 1971, Bangladesh is a unitary multiparty parliamentary republic with an elected national parliament called the Jatiyo Sangshad.[8] It is a member of the United Nations, the Commonwealth of Nations, the OIC, NAM, the Developing 8 Countries and BIMSTEC. A long-standing proponent of regional engagement in South Asia, Bangladesh pioneered the creation of SAARC. Its armed forces are among the world's largest contributors to United Nations
