Satyagraha loosely translated as "soul force" or "truth force" is a particular philosophy and practice within the broader overall category generally known as nonviolent resistance or civil resistance. The term "satyagraha" was conceived and developed by Mahatma Gandhi. He deployed satyagraha in the Indian independence movement and also during his earlier struggles in South Africa. Satyagraha theory influenced Nelson Mandela's struggle in South Africa under apartheid, Martin Luther King, Jr.'s campaigns during the civil rights movement in the United States, and many other social justice and similar movements. Someone who practices satyagraha is a satyagrahi.
