Final answer:
The Salt March was a significant protest organized by Mahatma Gandhi in 1930, challenging the British salt monopoly in India and symbolizing the broader struggle for Indian independence through an act of nonviolent civil disobedience.
Step-by-step explanation:
The protest organized by Gandhi that began with around a month of marching was the Salt March. This historical event commenced on March 12, 1930, when Mahatma Gandhi led his followers on a two-hundred-mile journey over the course of twenty-four days to the Arabian Sea. The purpose of the march was to collect salt from the seawater, thereby defying the British law imposing a salt monopoly which required Indians to buy heavily taxed salt from British authorities. Gandhi's act of civil disobedience was aimed at highlighting the unfairness of the British colonial rule in India and gained significant attention and support, leading to the arrest of Gandhi and approximately sixty thousand others.
Through such nonviolent resistance, Gandhi not only protested against specific unjust laws but also underscored the struggle for Indian independence. The Salt March is notable for its nonviolent approach and played a crucial role in the Indian independence movement, gathering momentum for subsequent civil disobedience actions and ultimately contributing to the end of British colonial rule in India.
