Chakmara is a branch of the Mongolian nation and belongs to Buddhism. Apart from Buddhism, one of their major festivals is Biju. Their main livelihood is agricultural work. Through the cultivation of jum, they produce various food crops and rabi crops.
There is no clear history of the Chakmas origin, their origin and their origin in the Chittagong Hill Tracts, or in the Chittagong Hill Tracts. However, it is certain from the information obtained so far, that the Chakmas reside in Chittagong Hill Tracts even in the first half of the seventeenth century. The history of the arrival of the Chakmas to Chittagong in 122 is proof. Champak Nagar was the capital of the state of Chakma at the beginning of the eighth century, near the Brahmaputra of Upper Assam. In the course of time, due to the rise and fall of the Chakma Rajasthan and clashes with the Burma-Mughals, the Chakma’s habitation and the state extends northeast to Chittagong Hill Tracts, Sharkul and Chittagong’s Rangunia on the banks of the river Shankh.
