Explanation: The Kols, along with other tribes, are inhabitants of Chhotanagpur. This covered Ranchi, Singhbhum, Hazaribagh, Palamau and the western parts of Manbhum.

• The trouble in 1831 started with large-scale transfers of land from Kol headmen to outsiders like Hindu, Sikh and Muslim farmers and moneylenders who were oppressive and demanded heavy taxes.
• Besides, the British judicial and revenue policies badly affected the traditional social conditions of the Kols.
• The Kols resented this and in 1831, under the leadership of Buddho Bhagat, the Kol rebels killed or burnt about a thousand outsiders.
