ASDC was active in the districts of Karbi Anglong and Dima Hasao (North Chachar Hills). Several elections to the Lok Sabha and the District Council were won under ASDC banner. Dr. Jayanta Rongpi represented the area in the Lok Sabha, elected as the ASDC candidate in 1991, 1996 and 1998. Later, ASDC split into two, with one section the Autonomous State Demand Committee (United) breaking away from CPI(ML) Liberation and aligning with the Bharatiya Janata Party.
In 2015, a group of former leaders from the Autonomous State Demand Committee (ASDC) established a new political party known as the Hills State Demand Council (HSDC). The HSDC's primary objective was to continue ASDC's advocacy for the creation of a separate state for the hill districts of Assam. The new party sought to pursue this goal with a transformed dynamism.[4]
