The Munda Rebellion of 1899-1900 led by Birsa Munda occurred in the region of Chotanagpur. Chotanagpur is a plateau region in eastern India, located in the states of Jharkhand, Odisha, and Chhattisgarh. It is home to a number of indigenous tribes, including the Munda, Oraon, and Ho. The Munda Rebellion was a major uprising against British colonial rule. It was led by Birsa Munda, a charismatic tribal leader who preached a return to traditional Munda values and a rejection of British rule. The rebellion was ultimately unsuccessful, but it had a significant impact on the history of India.
