Koch people
The Koch are a small trans-border ethnic group of Assam and Meghalaya in India and northern Bangladesh. The group consists of nine matrilineal and strictly exogamous clans, with some of them preserving a hitherto sparsely documented Boro-Garo language called Koch, whereas others have switched to local varieties of Indo-Aryan languages. It is a Scheduled Tribe in Meghalaya, India. Koches want to preserve their language, culture and heritage.
The Koch people in this group are those who have preserved their languages, their animistic religions and follow non-Hindu customs and traditions. They are related but distinguished from the empire building Koch and the Hindu caste called Koch in Upper Assam which receives converts from different tribes.
Etymology of ''Koch''
According to Tabaqat-i-Nasiri, western Kamrud was inhabited by the Koch, Mech & Tharu. In Yogini Tantra, Koches were called as Kuvachas. According to the Fatiyah-i-Ibriah written between 1661 and 1663, Cooch Behar was inhabited by Koch.Groups and clans
The Koch people consist of nine ethno-linguistic groups: Tintekiya, Wanang, Koch-Rabha/Kocha, Harigaya, Margan, Chapra, Satpari, Sankar and Banai. These groups are generally endogamous, with very little intermarriages till recently. Each of these nine groups have matrilineal and strictly exogamous clans called nikini. The matrilineal rules of the Koch are not as rigid as the Garo and the Khasi peoples.The group that is known as Kocha in Assam's Dhubri and Kokrajhar districts, identify with the Rabha people, and are also known as Koch-Rabha. Since the name Koch in Assam is associated with the caste Koch, this identity allows the Kocha people to benefit from state support that are open to the Rabha but not to the Koch. Advisor of Koch Development Council, writer and social worker Indramohan Koch said that the government of Meghalaya accorded ST status to Koch People while the Assam Government had not recognised them as Koch but ST status had been given in the name of Rabha.
