Wanchuwa Festival is celebrated in which State of India?

State Wise GK items on regional festivals test a precise pairing: each indigenous or tribal harvest festival belongs to one specific community and, through that community, to one specific Indian state. Exam-setters expect the exact community-festival-state link, not just a familiarity with 'some North-Eastern festival' or 'a harvest celebration'.

Wanchuwa (also spelled Wanshuwa) is a religious harvest festival of the Tiwa (Lalung) tribe, observed once every five or six years mainly in the Amkha and Marjong villages of Karbi Anglong district, and more broadly across Karbi Anglong, Morigaon and Nagaon districts. Over a Tuesday-to-Thursday cycle, the Shangdoloi (dormitory head) and villagers pound wet rice into flour at the ceremonial sham (wooden mortars), prepare the rice cake 'wanrusa', and offer it to the deities Sodonga Raja and Maldewa Raja — placing the festival, and the Tiwa community, in Assam.

• West Bengal's signature agrarian festival is Nabanna (the new-rice harvest celebration) — a distinct Bengali tradition, not Wanchuwa.

• Kerala's major harvest festival is Onam, marked by Pookalam and Vallam Kali — unconnected to the Tiwa community or Wanchuwa.

• Tripura's own tribal harvest festival is Garia Puja — a natural guess given this question comes from a Tripura-focused exam, but Wanchuwa is not observed there.
