$\mathbb{ANSWER}$

The Salt March, also known as the Dandi March and the Dandi Satyagraha, was an act of nonviolent civil disobedience in colonial India led by Mohandas Karamchand Gandhi to produce salt from the seawater in the coastal village of Dandi (now in Gujarat), as was the practice of the local populace until British officials introduced taxation on salt production, deemed their sea-salt reclamation activities illegal, and then repeatedly used force to stop it.

The 24-day march lasted from 12 March 1930 to 6 April 1930 as a direct action campaign of tax resistance and nonviolent protest against the British salt monopoly. It gained worldwide attention which gave impetus to the Indian independence movement and started the nationwide Civil Disobedience Movement. Mahatma Gandhi started this march with 78 of his trusted volunteers. The march was over 240 miles. They walked for 24 days 10 miles a day.

The march was the most significant organised challenge to British authority since the Non-cooperation movement of 1920–22, and directly followed the Purna Swaraj declaration of sovereignty and self-rule by the Indian National Congress on 26 January 1930.
