Gandhi launched a nonviolent civil disobedience campaign in India in 1930 to protest the British salt tax and demand self-rule. He led thousands on a 240 mile march to the coast to illegally produce salt, which symbolized British oppression. As the movement grew, people boycotted foreign goods and violated other laws, leading to violent clashes and over 100,000 arrests. Gandhi temporarily suspended the movement after negotiating with the viceroy, but relaunched it after continued British repression. The movement continued for over a year but gradually lost momentum.
