He wasn't the first, nor would he be the last, but the wiry, bespectacled man from Gujarat is certainly the most famous of the world's peaceful political dissidents. Mohandas Gandhi – also affectionately known as Mahatma – led India's independence movement in the 1930s and 40s by speaking softly without carrying much of a big stick, facing down the British colonialists with stirring speeches and non-violent protest. More than anything else, historians say, Gandhi proved that one man has the power to take on an empire, using both ethics and intelligence.

Urges Britain to quit India

It is hard to imagine the thin, robed Gandhi working in the rough and tumble world of law, but Gandhi did get his start in politics as a lawyer in South Africa, where he supported the local Indian community's struggle for civil rights. Returning to India in 1915, he carried over his desire to improve the situation of the lower classes.

Gandhi quickly became a leader within the Indian National Congress, a growing political party supporting independence, and traveled widely with the party to learn about the local struggles of various Indian communities.

It was during those travels that his legend grew among the Indian people, historians say.

Gandhi was known as much for his wit and intelligence as for his piety. When he was arrested several more times over the years for his actions during the movement,  Gandhi calmly fasted in prison, believing that his death would embarrass the British enough to spur independence, which had become the focus of his politics by 1920.

Gandhi's non-cooperation movement, kicked off in the early 1920s, called for Indians to boycott British goods and traditions and become self-reliant. His most famous protest came in 1930, when Gandhi led thousands of Indians on a 250-mile march to a coastal town to produce salt, on which the British had a monopoly.
