In 1957, Eastern Pakistan (present-day Bangladesh) begins building the Kaptai Hydroelectric Dam on the Karnaphuli River in the Chittagong Hills Tract in the southeast. Completed in 1962, the dam flooded 655 square kilometers of land and displaced 100,000 people, most of them Jumma, or ethnic minorities in a country ruled by a Bengali majority. The displaced Jumma are offered little land or compensation and many flee to neighboring India. These conditions contributed to 20+ years of conflict.
