ZThe Salt March, also known as the Salt Satyagraha, began with the Dandi March on March 12, 1930, and was an important part of the Indian independence movement, says Wikipedia.

It was a direct action campaign of tax resistance and nonviolent protest against the British salt monopoly in colonial India, and triggered the wider Civil Disobedience Movement.

This was the most significant organized challenge to British authority since the Non-cooperation movement of 1920–22
