Historically , the Kirati Tripuri converted Hindu rulers of Tripura 's Manikya dynasty had always encouraged the immigration of and settlement of non-tribals , especially Bengalis to Tripura . Rajmala authenticates the fact that Ratna Manikya ( 1464-1468 ) was the first to ‘ settle 4000 Bengalis in four places ’ in Tripura . During Noakhali riots in 1946 many Bengali Hindu survivors referred to as East Bengali Refugees were sheltered in temporary relief camps in Comilla , Chandpur , Agartala the present capital of Tripura and other places . A large migration of Bengali Hindus and Muslims took place in Assam , Meghalaya , Tripura and other places during Bangladesh Liberation War on 1971
