The Salt March, also known as the Salt Satyagraha, Dandi March and the Dandi Satyagraha, was an act of nonviolent civil disobedience in colonial India led by Mahatma Gandhi. The twenty-four day march lasted from 12 March 1930 to 6 April 1930 as a direct action campaign of tax resistance and nonviolent protest against the British salt monopoly. Another reason for this march was that the Civil Disobedience Movement needed a strong inauguration that would inspire more people to follow Gandhi's example. Gandhi started this march with 78 of his trusted volunteers. The march spanned 239 miles (385 km), from Sabarmati Ashram to Dandi, which was called Navsari at that time (now in the state of Gujarat). Growing numbers of Indians joined them along the way. When Gandhi broke the British Raj salt laws at 8:30 am on 6 April 1930, it sparked large scale acts of civil disobedience against the salt laws by millions of Indians.After making the salt by evaporation at Dandi, Gandhi continued southward along the coast, making salt and addressing meetings on the way. The Congress Party planned to stage a satyagraha at the Dharasana Salt Works, 25 mi (40 km) south of Dandi. However, Gandhi was arrested on the midnight of 45 May 1930, just days before the planned action at Dharasana. The Dandi March and the ensuing Dharasana Satyagraha drew worldwide attention to the Indian independence movement through extensive newspaper and newsreel coverage. The satyagraha against the salt tax continued for almost a year, ending with Gandhi's release from jail and negotiations with Viceroy Lord Irwin at the Second Round Table Conference. Although over 60,000 Indians were jailed as a result of the Salt Satyagraha, the British did not make immediate major concessions.The Salt Satyagraha campaign was based upon Gandhi's principles of non-violent protest called satyagraha, which he loosely translated as "truth-force". Literally, it is formed from the Sanskrit words satya, "truth", and agraha, "insistence". In early 1920 the Indian National Congress chose satyagraha as their main tactic for winning Indian sovereignty and self-rule from British rule and appointed Gandhi to organise the campaign. Gandhi chose the 1882 British Salt Act as the first target of satyagraha. The Salt March to Dandi, and the beating by the colonial police of hundreds of nonviolent protesters in Dharasana, which received worldwide news coverage, demonstrated the effective use of civil disobedience as a technique for fighting social and political injustice. The satyagraha teachings of Gandhi and the March to Dandi had a significant influence on American activists Martin Luther King Jr., James Bevel, and others during the Civil Rights Movement for civil rights for African Americans and other minority groups in the 1960s. The march was the most significant organised challenge to British authority since the Non-cooperation movement of 192022, and directly followed the Purna Swaraj declaration of sovereignty and self-rule by the Indian National Congress on 26 January 1930. It gained worldwide attention which gave impetus to the Indian independence movement and started the nationwide Civil Disobedience movement which continued until 1934.

Mohandas Karamchand Gandhi (; GAHN-dee; 2 October 1869 – 30 January 1948), also known as Gandhi, was an Indian lawyer, anti-colonial nationalist and political ethicist who employed nonviolent resistance to lead the successful campaign for India's independence from British rule, and to later inspire movements for civil rights and freedom across the world. The honorific Mahātmā (Sanskrit: "great-souled", "venerable"), first applied to him in 1914 in South Africa, is now used throughout the world.Born and raised in a Hindu family in coastal Gujarat, Gandhi trained in the law at the Inner Temple, London, and was called to the bar at age 22 in June 1891. After two uncertain years in India, where he was unable to start a successful law practice, he moved to South Africa in 1893 to represent an Indian merchant in a lawsuit. He went on to live in South Africa for 21 years. It was here that Gandhi raised a family and first employed nonviolent resistance in a campaign for civil rights. In 1915, aged 45, he returned to India and soon set about organising peasants, farmers, and urban labourers to protest against excessive land-tax and discrimination.

Assuming leadership of the Indian National Congress in 1921, Gandhi led nationwide campaigns for easing poverty, expanding women's rights, building religious and ethnic amity, ending untouchability, and, above all, achieving swaraj or self-rule. Gandhi adopted the short dhoti woven with hand-spun yarn as a mark of identification with India's rural poor. He began to live in a self-sufficient residential community, to eat simple food, and undertake long fasts as a means of both introspection and political protest. Bringing anti-colonial nationalism to the common Indians, Gandhi led them in challenging the British-imposed salt tax with the 400 km (250 mi) Dandi Salt March in 1930 and in calling for the British to quit India in 1942. He was imprisoned many times and for many years in both South Africa and India.

Gandhi's vision of an independent India based on religious pluralism was challenged in the early 1940s by a Muslim nationalism which demanded a separate homeland for Muslims within British India. In August 1947, Britain granted independence, but the British Indian Empire was partitioned into two dominions, a Hindu-majority India and a Muslim-majority Pakistan. As many displaced Hindus, Muslims, and Sikhs made their way to their new lands, religious violence broke out, especially in the Punjab and Bengal. Abstaining from the official celebration of independence, Gandhi visited the affected areas, attempting to alleviate distress. In the months following, he undertook several hunger strikes to stop the religious violence. The last of these, begun in Delhi on 12 January 1948 when he was 78, also had the indirect goal of pressuring India to pay out some cash assets owed to Pakistan. Although the Government of India relented, as did the religious rioters, the belief that Gandhi had been too resolute in his defence of both Pakistan and Indian Muslims, especially those besieged in Delhi, spread among some Hindus in India. Among these was Nathuram Godse, a militant Hindu nationalist from western India, who assassinated Gandhi by firing three bullets into the chest at an inter-faith prayer meeting in Delhi on 30 January 1948.Gandhi's birthday, 2 October, is commemorated in India as Gandhi Jayanti, a national holiday, and worldwide as the International Day of Nonviolence. Gandhi is commonly, though not formally, considered the Father of the Nation in India and was commonly called Bapu (Gujarati: endearment for father, papa).
