Bangladesh is an abode of scores of ethnic minorities from time immemorial. Historical evidence as well as anthropological writings on this subject suggests that adivasis of north-west Bangladesh came to settle in this region during the colonial era in the look out of a better and more secured life. They came from different parts of Indian sub continent; most prominently recalled names are Bhagalpur, Dumka, Chotonagpur, Rajmahal, Ghatshila, Birbhum Ranchi etc. Initially they got hold of land from the local landlords with this condition that they would clear the jungle for very low rents.

Introductory Remarks  Bangladesh's tribal population consists of about 1 million people, just under 1 percent of the total population. They live primarily in the Chittagong Hills and in the regions of Mymensingh, Sylhet, and Rajshahi. The majority of the tribal population (778,425) live in rural settings, where many practice shifting cultivation. Most tribal people are of SinoTibetan descent and has distinctive Mongoloid features. They differ in their social organization, marriage customs, birth and death rites, food, and other social customs from the people of the rest of the country. They speak Tibeto-Burman languages. In the mid-1980s, the percentage distribution of tribal population by religion was Hindu 24, Buddhist 44, Christian 13, and others 19.

Introductory Remarks  The four largest tribes are the Chakmas, Marmas (or Maghs), Tipperas (or Tipras), and Mros (or Moorangs). The tribes tend to intermingle and could be distinguished from one another more by differences in their dialect, dress, and customs than by tribal cohesion. Only the Chakmas and Marmas display formal tribal organization, although all groups contain distinct clans. By far the largest tribe, the Chakmas are of mixed origin but reflect more Bengali influence than any other tribe. Unlike the other tribes, the Chakmas and Marmas generally live in the highland valleys. Most Chakmas are Buddhists, but some practiced Hinduism or animism.
