The borders of present-day Bangladesh were established with the partition of Bengal and India in 1947, when the region became East Pakistan, part of the newly formed Islamic State of Pakistan. However, it was separated from the western wing by 1,600 km (994 mi) of Indian territory. Due to political exclusion, ethnic and linguistic discrimina­tion, as well as economic neglect by the politically-dominant West Pakistan, popular agitation led by Sheikh Mujibur Rahman grew against West Pakistan, resulting in the Bangladesh Liberation War of 1971, which the Bengali people won with the support of India. After independence, the new state endured famine, natural disasters and wide­spread poverty, as well as political turmoil and military coups.The restoration of democ­racy in 1991 has been followed by relative calm and economic progress.
