Nonviolence is a philosophy and strategy for social change that rejects the use of violence. As such, nonviolence is an alternative to passive acceptance of oppression and armed struggle against it. Practitioners of nonviolence may use diverse methods in their campaigns for social change, including critical forms of education and persuasion, civil disobedience and nonviolent direct action, and targeted communication via mass media.
In modern times, nonviolence has been a powerful tool for social protest. There are many examples of its being used in nonviolent resistance and nonviolent revolution, including Mahatma Gandhi leading a decades-long nonviolent struggle against British rule in India, which eventually helped India win its independence in 1947, Martin Luther King's adoption of Gandhi's nonviolent methods in the struggle to win civil rights for African Americans, and César Chávez's campaigns of nonviolence in the 1960s to protest the treatment of farm workers in California. The 1989 "Velvet Revolution" in Czechoslovakia that saw the overthrow of the Communist government is considered one of the most important of the largely nonviolent Revolutions of 1989. Most recently the nonviolent campaigns of Leymah Gbowee and the women of Liberia were able to achieve peace after a 14-year civil war. This story is captured in a 2008 documentary film Pray the Devil Back to Hell.
The term "nonviolence" is often linked with or even used as a synonym for pacifism; however, the two concepts are fundamentally different. Pacifism denotes the rejection of the use of violence as a personal decision on moral or spiritual grounds, but does not inherently imply any inclination toward change on a sociopolitical level. Nonviolence on the other hand, presupposes the intent of (but does not limit it to) social or political change as a reason for the rejection of violence. Also, a person may advocate nonviolence in a specific context while advocating violence in other contexts.[
