Mahatma Gandhi started the Salt March, also known as the Dandi March, on March 12, 1930, from Sabarmati Ashram in Ahmedabad, Gujarat. The march was a non-violent protest against the British monopoly on salt production and sales. It covered a distance of about 240 miles (385 kilometers) to the coastal village of Dandi, where Gandhi broke the salt laws by making salt from seawater. This act was a significant part of the Indian independence movement and helped to mobilize a wide swath of Indian society against British colonial rule.
