The Rakhine (Arakanese) from present-day Rakhine State (Arakan) in Western Myanmar and the Marma from the Chittagong Hill Tracts (CHT) of Southeast Bangladesh originated from the same region, share the same culture and practice the same religion. However, the people from CHT have developed a distinctive identity and are individualized by a different name “Marma”. This development raises a number of historical questions. This paper explores how the Arakanese descendants became “Marma” in Bangladesh.
