1917        

Champaran Satyagraha (1917): In Champaran district of Bihar the condition of Indigo cultivators became miserable under Tinkathiya system. Under this system the cultivators were forced to cultivate Indigo on the best 3/20th part of their land and were forced to sell them at a cheaper price. The situation for the farmers became worse due to harsh weather conditions and levy of heavy taxes. Then, Rajkumar Shukla met Mahatma Gandhi at Lucknow and invited him.
At Champaran, Mahatma Gandhi adopted the approach of civil disobedience movement and launched demonstrations and strikes against the landlords. As a result, the government set up a Champaran agrarian committee of which Gandhi ji was also one of the members. All the demands of the cultivators were accepted and the Satyagraha was successful.
