Explanation: The Pagal Panthi, a semi-religious group mainly constituting the Hajong and Garo tribes of Mymensingh district (earlier in Bengal), was founded by Karam Shah.

• But the tribal peasants organised themselves under Karam Shah’s son, Tipu, to fight the oppression of the zamindars.
• From 1825 to 1835, the Pagal Panthis refused to pay rent above a certain limit and attacked the houses of zamindars.
