Explanation:

Champaran Satyagraha (1917)—First Civil Disobedience.
Gandhi was requested by Rajkumar Shukla to look into the problems of the indigo planters, of Champaran in Bihar.
The European planters had been forcing peasants to grow indigo on 3/20 of the total land (called tinkathia system).
When Gandhi, joined now by Rajendra Prasad, Mazharul-Haq, Mahadeo Desai, Narhari Parekh, J.B. Kripalani, reached Charnparan to probe into the matter, the authorities ordered him to leave the area at once. Gandhi defied the order and preferred to face the punishment. This passive resistance or civil disobedience of an unjust order was a novel method at that time.
Gandhi was able to convince the authorities that the tinkathia system should be abolished and that the peasants should be compensated for the illegal dues extracted from them.
