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.
