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. It is largely but wrongly taken as synonymous with civil resistance. Each of these terms—nonviolent resistance and civil resistance—has its distinct merits and also quite different connotations and commitments.
Major nonviolent resistance advocates include Mahatma Gandhi, Henry David Thoreau, Te Whiti o Rongomai, Tohu Kākahi, Leo Tolstoy, Alice Paul, Martin Luther King, Jr, James Bevel, Václav Havel, Andrei Sakharov, Lech Wałęsa, Gene Sharp, and many others. There are hundreds of books and papers on the subject—see Further reading below.
From 1966 to 1999, nonviolent civic resistance played a critical role in fifty of sixty-seven transitions from authoritarianism.[1] Recently, nonviolent resistance has led to the Rose Revolution in Georgia and the Orange Revolution in Ukraine. Current nonviolent resistance includes the Jeans Revolution in Belarus, the "Jasmine" Revolution in Tunisia, and the fight of the Cuban dissidents. Many movements which promote philosophies of nonviolence or pacifism have pragmatically adopted the methods of nonviolent action as an effective way to achieve social or political goals. They employ nonviolent resistance tactics such as: information warfare, picketing, marches, vigils, leafletting, samizdat, magnitizdat, satyagraha, protest art, protest music and poetry, community education and consciousness raising, lobbying, tax resistance, civil disobedience, boycotts or sanctions, legal/diplomatic wrestling, underground railroads, principled refusal of awards/honors, and general strikes. Nonviolent action differs from pacifism by potentially being proactive and interventionist.
A great deal of work has addressed the factors that lead to violent mobilization, but less attention has been paid to understanding why disputes become violent or nonviolent, comparing these two as strategic choices relative to conventional politics.[2]
