The Arakan Mountains divide the Rakhine coast from the rest of Myanmar, and thus have acted as a barrier between the peoples of central Myanmar and those of the Indian subcontinent. This played a role in fostering the separate development of the
Rakhine people, both linguistically and culturally, from the
Burmese. The Arakan Mountains also served as a barrier inhibiting Burmese invasions, and allowing Arakan to develop as a separate political entity. Thus the coastal cities, such as
Mrauk U and
Waithali, formed the core of Arakan civilization. There were fierce battles in these mountains between January 1943 and March 1944 during the
Japanese occupation of Burma. The Japanese 33rd and 55th Divisions faced the British military on the coastal side of the range. The British forces won. ==Ecology==
