Gandhi in 1918, at the time of the Kheda and Champaran satyagrahasGandhi's first major achievements came in 1918 with the Champaran and Kheda agitations of Bihar and Gujarat. The Champaran agitation pitted the local peasantry against their largely British landlords who were backed by the local administration. The peasantry was forced to grow Indigo, a cash crop whose demand had been declining over two decades, and were forced to sell their crops to the planters at a fixed price. Unhappy wIth this, the peasantry appealed to Gandhi at his ashram in Ahmedabad. Pursuing a strategy of non-violent protest, Gandhi took the administration by surprise and won concessions from the authorities.
In 1918, Kheda was hit by floods and famine and the peasantry was demanding relief from taxes. Gandhi moved his headquarters to Nadiad, 39] organising scores of supporters and fresh volunteers from the region, the most notable being Vallabhbhai Patel.  Using non-cooperation as a technique, Gandhi initiated a signature campaign where peasants pledged non-payment of revenue even under the threat of confiscation of land. A social boycott of mamlatdars and talatdars (revenue officials within the district) accompanied the agitation. Gandhi worked hard to win public support for the agitation across the country. For five months, the administration refused but finally in end-May 1918, the Government gave way on important provisions and relaxed the conditions of payment of revenue tax until the famine ended. In Kheda, Sardar Patel represented the farmers in negotiations with the British, who suspended revenue collection and released all the prisoners.
