The Salt Satyagraha campaign that began in 1930 sought to continue previous efforts that had attempted to undermine British colonial rule in India and establish Purna Swaraj (complete self-rule). The previous nationwide nonviolent campaign for independence (1919-22) had been called off by Gandhi because it broke into disarray and violence, even though it had been preceded by local campaigns: a campaign in Champaran (Indian peasants in Champaran campaign for rights, 1917) and a textile workers strike in Ahmedabad in 1918.
During the time of British occupation of India, peasants of Champaran district of the Bihar state were highly exploited by the indigo cultivation. The lessees of Indigo and agricultural areas had been Indians until 1793, but as the British Empire began its rule in India, European planters began to take over and gained total control of the indigo and sugar cane cultivation.
In March 1942, the British Parliament sent a delegation to India under Sir Stafford Cripps, a Labor Party Politician, in order to negotiate with the Indian National Congress a constitution that would secure Indian support of World War II. The Indian National Congress (INC) found the proposal for the new constitution unsatisfactory, since the draft declaration promised India domination status—but not complete independence—in return for its total cooperation during the war.
