The Jumma people is a collective term for the indigenous peoples of the Chittagong Hill Tracts region of present-day Bangladesh. They include the Chakma, Marma, Tripuri, Tanchangya, Chak, Pankho, Mru, Bawm, Lushai, Khyang, Gurkha, Assamese, Santal, and Khumi.
The name jumma ("jum farmer") is derived from jum cultivation, or slash-and-burn farming. It is a reappropriated term originally used by outsiders. They are also known as Pahari, which simply means "hill people".
The Jummas are native speakers of Tibeto-Burman languages, unrelated to Bangla spoken by ethnic Bengalis. Religiously they are distinct as well, most being Buddhist, some Hindu and some are Christianized, with only a small number of having converted to Islam. In addition, they have retained some traditional religious practices.
Persecution by Bengalis
Bengali settlers and soldiers have raped native Jumma (Chakma) women "with impunity" with the Bangladeshi security forces doing little to protect the Jummas and instead assisting the rapists and settlers.
