Explanation:

Viceroy Irwin received a letter from Mahatma Gandhi on January 31, 1930, in which he outlined and imposed eleven demands. The most compelling of all the requests was to do rid of the salt tax, which is paid for by both the rich and the poor. By March 11th, the demands had to be satisfied, or Congress will start a campaign of civil disobedience. 78 of his dependable volunteers marched with Mahatma Gandhi in the well-known salt march.

The march travelled more than 240 kilometres from Gandhiji’s ashram in Sabarmati to the coastal town of Dandi in Gujarat. He landed in Dandi on April 6 and ceremonially breached the law by salting seawater by scalding it. This movement served as the catalyst for the Civil Disobedience Movement.
