The Civil Disobedience Movement in India began with the Dandi March. The Dandi March, also known as the Salt Satyagraha, was a significant event during the Indian independence movement led by Mahatma Gandhi. On March 12, 1930, Gandhi and a group of followers set out on a march from Sabarmati Ashram to the coastal village of Dandi in Gujarat. The purpose of this march was to protest against the British salt tax, which heavily burdened the Indian population.

During the Dandi March, Gandhi and his followers collected or made their own salt from the seawater, directly violating the British salt monopoly. This act of civil disobedience inspired millions of Indians to join the movement and engage in non-cooperation with the British authorities. The Dandi March marked the beginning of a nationwide movement against British rule, and it greatly increased public participation in the struggle for Indian independence.
