Mahatma Gandhi launched the Civil Disobedience Movement in 1930.
The movement began on March 12, 1930 and ended on April 6, 1930.
The movement began with Gandhi's famous Dandi March, where he led a group of people from Sabarmati Ashram to Dandi, a village on the coast of Gujarat. Gandhi arrived in Dandi on April 6, 1930 and broke the law by making salt from seawater.
The movement was a protest against the British government and its salt tax, and was a form of non-cooperation to pressure the British to accept Indian demands. Gandhi believed it was sinful to tax salt because it was an essential food item.
