Mohandas Karamchand Gandhi (காந்தி | மோகன்தாசு கரம்சந்த் காந்தி 2 October 1869 – 30 January 1948) was a pre-eminent political and ideological leader of India during the Indian independence movement. He pioneered satyagraha. This is defined as resistance to tyranny through mass civil resistance - a term which Gandhi used in many of his statements and writings. His philosophy was firmly founded upon ahimsa (nonviolence). His philosophy and leadership helped India gain independence and inspired movements for civil rights and freedom across the world. Gandhi is often referred to as Mahatma (Sanskrit: महात्मा mahātmā or "Great Soul" (magnanimous), an honorific first applied to him by Rabindranath Tagore). In India, he is also called Bapu (Gujarati: બાપુ, bāpu or "Father") and officially honored in India as the Father of the Nation. His birthday, 2 October, is commemorated as Gandhi Jayanti, a national holiday, and worldwide as the International Day of Non-Violence. Gandhi was assassinated on 30 January 1948 by Nathuram Godse.
Gandhi first employed civil disobedience while an expatriate lawyer in South Africa, during the resident Indian community's struggle for civil rights. After his return to India in 1915, he organized protests by peasants, farmers, and urban laborers concerning excessive land-tax and discrimination. After assuming leadership of the Indian National Congress in 1921, Gandhi led nationwide campaigns to ease poverty, expand women's rights, build religious and ethnic amity, end untouchability, and increase economic self-reliance. Above all, he aimed to achieve Swaraj or the independence of India from foreign domination. Gandhi famously led his followers in the Non-cooperation movement that protested the British-imposed salt tax with the 400 km (240 mi) Dandi Salt March in 1930. He launched the Quit India Movement in 1942, demanding immediate independence for India. Gandhi spent a number of years in jail in both South Africa and India.
As a practitioner of ahimsa, Gandhi swore to speak the truth and advocated that others do the same. He lived modestly in a self-sufficient residential community and wore the traditional Indian dhoti and shawl, woven from yarn that he had spun by hand himself. He ate simple vegetarian food, experimented for a time with a fruitarian diet, and undertook long fasts as a means of both self-purification and social protest.
