Which powerful and influential organization provided leadership to support peasant uprisings?

The powerful organisations that supported peasant uprisings were historically mostly Communists

Explanation:

Communists had been responsible for the support of the peasant uprising across the world in the later part of the 19th century and that is not necessarily a bad thing.

The uprising was against the fact that there were too many issues with the life of the peasant that were simply not addressed by the government and they were left to lead a life of difficulty.

By this, they were able to assert themselves on the center  of the conflict and say that they had rights too.
