Koch (caste)

Koch is a social group in the Indian state of Assam. The members of the caste are converts from different ethnic groups such as the Bodos, Garos, Tiwas, Karbis, Ahoms, Hajongs, Chutias etc. The Koch is one of many categories in the tribe-caste continuum in Assamese society. In some instance, the identity of the Koch overlaps the identity of the Kachari. Any member of the any ethnic group can become a Koch by employing a Brahmin and giving up habits such as the consumption of liquor, pork, beef etc. and giving up their original mother tongue which are considered to be impure in Hinduism. The caste is mostly found to be concentrated in Upper Assam section of the Brahmaputra Valley.
