Salt March in the context of "Sabarmati Ashram"

Nonviolent resistance, or nonviolent action, sometimes called civil resistance, is the practice of achieving goals such as social change through symbolic protests, civil disobedience, economic or political noncooperation, satyagraha, constructive program, or other methods, while refraining from violence and the threat of violence. This type of action highlights the desires of an individual or group that feels that something needs to change to improve the current condition of the resisting person or group.

Mahatma Gandhi is the most popular figure related to this type of protest; United Nations celebrates Gandhi's birthday, October 2, as the International Day of Non-Violence. Other prominent advocates include Abdul Ghaffar Khan, Henry David Thoreau, Etienne de la Boétie, Charles Stewart Parnell, Te Whiti o Rongomai, Tohu Kākahi, Leo Tolstoy, Alice Paul, Martin Luther King Jr., Daniel Berrigan, Philip Berrigan, James Bevel, Václav Havel, Andrei Sakharov, Lech Wałęsa, Gene Sharp, Nelson Mandela, Jose Rizal, and many others. From 1966 to 1999, nonviolent civic resistance played a critical role in fifty of sixty-seven transitions from authoritarianism.

Civil disobedience is the active and professed refusal of a citizen to obey certain laws, demands, orders, or commands of a government (or any other authority). By some definitions, civil disobedience has to be nonviolent to be called "civil". Hence, civil disobedience is sometimes equated with peaceful protests or nonviolent resistance. Henry David Thoreau's essay Resistance to Civil Government, first published in 1849 and then published posthumously in 1866 as Civil Disobedience, popularized the term in the US, although the concept itself was practiced long before this work.

Various forms of civil disobedience have been used by prominent activists, such as American women's suffrage leader Susan B. Anthony in the late 19th century, Egyptian nationalist Saad Zaghloul during the 1910s, and Indian nationalist Mahatma Gandhi in 1920s British India as part of his leadership of the Indian independence movement. Martin Luther King Jr.'s and James Bevel's peaceful nonviolent protests during the civil rights movement in the 1960s United States sometimes contained important aspects of civil disobedience. Although civil disobedience is rarely justifiable in court, King regarded civil disobedience to be a display and practice of reverence for law: "Any man who breaks a law that conscience tells him is unjust and willingly accepts the penalty by staying in jail to arouse the conscience of the community on the injustice of the law is at that moment expressing the very highest respect for the law."

Satyāgraha (from Sanskrit: सत्याग्रह; satya: "truth", āgraha: "insistence" or "holding firmly to"), or "holding firmly to truth", or "truth force", is a particular form of nonviolent resistance or civil resistance. Someone who practises satyagraha is a satyagrahi.

The term satyagraha was coined and developed by Mahatma Gandhi (1869–1948) as early as 1919.Gandhi practised satyagraha as part of the Indian independence movement and also during his earlier struggles in South Africa for Indian rights. Satyagraha theory influenced Martin Luther King Jr.'s and James Bevel's campaigns during the Civil Rights Movement in the United States, as well as Nelson Mandela's struggle against apartheid in South Africa and many other social-justice and similar movements.

A salt tax refers to the direct taxation of salt, usually levied proportionately to the volume of salt purchased. The taxation of salt dates as far back as 300 BC, as salt has been a valuable good used for gifts and religious offerings at least since 6050 BC. As a result of the successful profitability of the salt tax, its use would diffuse among governments across the world. France, Spain, Russia, England, and India were the main regions to follow the Chinese lead. Salt was used as a currency during the Roman Empire, and towards the end of their reign the Romans began monopolising salt in order to fund their war objectives. Salt was such an important commodity during the Middle Ages that salt production facilities became some of the first state-owned enterprises. Salt is one of the longest standing sources of revenue for governments; the taxation policy was so successful due to the vital role of salt within the human diet. Salt taxes have been extremely influential in many of the political and economic revolts within history, resulting in important historic events including the French Revolution, the Moscow Salt Riot, the Salt March in India, and the Salt Tax Revolt in Spain.

Tax resistance is the refusal to pay tax because of opposition to the government that is imposing the tax, or to government policy, or as opposition to taxation in itself. Tax resistance is a form of direct action and, if in violation of the tax regulations, also a form of civil disobedience. Tax resisters are distinct from "tax protesters", who deny that the legal obligation to pay taxes exists or applies to them. Tax resisters may accept that some law commands them to pay taxes but they still choose to resist taxation.

Examples of tax resistance campaigns include those advocating home rule, such as the Salt March led by Mahatma Gandhi, and those promoting women's suffrage, such as the Women's Tax Resistance League. War tax resistance is the refusal to pay some or all taxes that pay for war and may be practiced by conscientious objectors, pacifists, or those protesting against a particular war.
