Indigenous peoples in Bangladesh
The Khasi are an indigenous or tribal people, the majority of whom live in the State of Meghalaya in north east India, with small populations in neighbouring Assam, and in parts of Bangladesh. They call themselves Ki Hynñiew trep, which means "the seven huts" in the Khasi language. Their language Khasi is the northernmost Austroasiatic language. This language was essentially oral until the arrival of European missionaries. Particularly significant in this regard was a Welsh missionary, Thomas Jones, who transcribed the Khasi language into Roman Script. The Khasi people form the majority of the population of the eastern part of Meghalaya. A substantial minority of the Khasi people follow their tribal religion; called variously, Ka Niam Khasi and Ka Niam Tre in the Jaintia region and within that indigenous religious belief the rooster is sacrificed as a substitute for man, it being thought that the rooster "bears the sins of the man and by its sacrifice, man will obtain redemption"[2](compare Kapparot). Other religions practised include Presbyterian, Anglican, Unitarian, Roman Catholic and very few are Muslims. The Khasi people who reside in the hilly areas of Sylhet, Bangladesh are of the War sub-tribe. The main crops produced by the Khasi people living in the War areas, including Bangladesh, are betel leaf, areca nut and oranges. The War-Khasi people designed and built the living root bridges of the Cherrapunjee region.[3] In several States of India, Khasis have been granted the status of Scheduled tribe. The Khasis are a matrilineal society.
