There are numerous examples, but Gandhi's salt march is one of the best known:
Gandhi led the Dandi March from his base, Sabarmati Ashram, near the city of Ahmedabad. 78 people began the march with Gandhi, who intended to walk 240 miles (390 km) to the coastal village of Dandi, which was located at a small town called Navsari in the state of Gujarat. As Gandhi and the others continued on what would become a 24-day march to Dandi to produce salt without paying the tax, growing numbers of Indians joined them along the way. When Gandhi broke the salt laws at 6:30 am on 6 April 1930, it sparked large scale acts of civil disobedience against the British Raj salt laws by millions of Indians. The campaign had a significant effect on changing world and British attitudes towards Indian sovereignty and self-rule and caused large numbers of Indians to join the fight for the first time.
The Satyagraha campaign of the 1930s also forced the British to recognise that their control of India depended entirely on the consent of the Indians – Salt Satyagraha was a significant step in the British losing that consent.
