The Phulaguri Revolt was a peasant uprising that took place in the Phulaguri district of Bengal in 1861. The revolt was led by a peasant named Titumir, who was opposed to the excessive revenue demands of the British East India Company. The revolt was suppressed by the British, but it is remembered as an important example of peasant resistance to British rule.
