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.
The Bombay Government (through its Revenue Department) had, in 1927, enhanced the land revenue assessment in the Bardoli taluka (county) by a nominal 22 percent, which, when applied, amounted in some cases to as much as 60 percent enhancement. This translated in increased land taxes. The Bardoli peasants had immediately made several claims regarding this modification, the most important of which were that the rate of enhancement was unjust and that it had been established without full and appropriate investigation.
