A nonviolent revolution is a revolution conducted primarily by unarmed civilians using tactics of civil resistance, including various forms of nonviolent protest, to bring about the departure of governments seen as entrenched and authoritarian without the use or threat of violence. While many campaigns of civil resistance are intended for much more limited goals than revolution, generally a nonviolent revolution is characterized by simultaneous advocacy of democracy, human rights, and national independence in the country concerned.
An effective campaign of civil resistance, and even the achievement of a nonviolent revolution, may be possible in a particular case despite the government in power taking brutal measures against protesters. The commonly held belief that most revolutions that have happened in dictatorial regimes were bloody or violent uprisings is not borne out by historical analysis. Nonviolent Revolutions came to the international forefront in the 20th century by the independence movement of India under the leadership of Gandhi with civil disobedience being the tool of nonviolent resistance. An important non-violent revolution was in Sudan in October 1964 which overthrew a military dictatorship. Later it became more successful and more common in the 1980s as Cold War political alliances which supported status quo governance waned.
