The section of the Bangladesh frontier in the south-east runs adjacent to the northern Arakan states of Myanmar (formerly, Burma) —a politically turbulent area which has, at least from the late 1940s, been featured by spells of high intensity conflict between the government of Myanmar and the Arakanese Muslims, the ‘Rohingya.’ The length of time over which the Rohingya have coexisted in this hilly area with the numerically larger ‘Rakhine’ — a predominantly Buddhist ethnic group— is not known with certainty. The Rohingya claim in this regard is that their roots could be traced back to the 10th century Muslim migrations into Burma, and that, in the northern Arakan, they constituted an independent principality for more than three centuries from 1430 to 1784.[i] This has been disputed. The official stand of the government of Myanmar (which has, in fact, been corroborated in certain scholarly writings) is that the Rohingya community consists largely of Bengali Muslims who migrated into this area after the annexation of Arakan by the British in 1843.
