Q. When did the Wilkinson Law come into force in Chhota Nagpur?
Answer: 1834
Notes: The Wilkinson Law was enforced in Chhota Nagpur in 1834 after the Kol uprising of 1831. It was framed by British officer Thomas Wilkinson to regulate land tenure and administration for tribal communities like Mundas, Oraons, Hos, and Bhumijs. The law recognized customary rights and aimed to govern according to tribal customs. It established a special administrative system distinct from other regions under British rule during that period.
