As in India's [[Tripura]] State, the Chakmas have lived in Bangladesh before it gained its independence. Recent migrations of ethnic Bengalis into traditionally Chakma regions of Bangladesh have raised tensions in the Chittagong Hill Tracts. Successive governments have dealt forcefully with Chakma uprisings and finally ended the conflict with [[Chittagong Hill Tracts#History|The 1997 Peace Treaty]]. This forceful dealing and the construction of Kaptai Dam by then-Pakistan government in Chakma areas submerged cultivable lands and displaced thousands, resulted in the migration of a large population of Chakmas into [[Diyun]] in the state of [[Arunachal Pradesh]] of India during 1964-1969.
