who was birsa munda? what was the impact of the munda rebellion?

Birsa Munda was an Indian tribal freedom fighter and a folk hero, who belonged to the Munda tribe. He spearheaded the Millenarian movement that rose in the tribal belt of modern day Bihar and Jharkhand

There were mainly two impacts:-   First it forced the colonial government to introduce laws so that the land of the tribals could not be easily taken away by the dikus. Second it showed once again that the tribal people had the capacity to protest against injustice and express their anger against colonial rule. They did this in their own way, inventing their own rituals and symbols of struggle.
