The Mizo District, formerly called Lushai Hills District, was an autonomous district of the Indian state of Assam from 1947 till 1972 until it was granted the status of a Union Territory. This region was a significant part of Mizo history as it formally abolished the Mizo chieftainship system in 1954. It also encountered the 1959 Mautam famine, which led to the Mizo National Front uprising and the subsequent 20-year insurgency.
