A strategy of social and political activism that involves using nonviolent resistance, protest, and direct action to challenge injustice, oppression, and inequality, and to bring about social change, often associated with movements such as the civil rights movement, anti-war protests, and campaigns for human rights and environmental justice. Nonviolent direct action may include tactics such as sit-ins, boycotts, marches, and civil disobedience, and is based on principles of moral and strategic nonviolence.
