Nonviolence has two (closely related) meanings: (1) It can refer, first, to a general philosophy of abstention from violence because of moral or religious principle (e.g. "She believes in nonviolence."), or (2) it can refer to the behaviour of people using nonviolent action (e.g. "The demonstrators maintained their nonviolence.")

Much of the general philosophy of nonviolence has 'active' or 'activist' elements, in that they accept the need for a means of struggle to achieve political and social change. Thus, for example, the Gandhian ahimsa is a philosophy and strategy for social change that rejects the use of violence, but at the same time sees nonviolent action (also called civil resistance) as an alternative to passive acceptance of oppression or armed struggle against it. In general, advocates of an activist philosophy of nonviolence use diverse methods in their campaigns for social change, including critical forms of education and persuasion, mass noncooperation civil disobedience and nonviolent direct action and social, political, cultural and economic forms of intervention.

Malcolm X ( /ˈmælkəm ˈɛks/; May 19, 1925 – February 21, 1965), born Malcolm Little and also known as El-Hajj Malik El-Shabazz (Arabic: الحاجّ مالك الشباز‎), was an African-American Muslim minister and human rights activist. To his admirers, he was a courageous advocate for the rights of African Americans, a man who indicted white America in the harshest terms for its crimes against black Americans. Detractors accused him of preaching racism, black supremacy, antisemitism, and violence. He has been called one of the greatest and most influential African Americans in history.

Malcolm X's father died—killed by white supremacists, it was rumored—when he was young, and at least one of his uncles was lynched. When he was thirteen, his mother was placed in a mental hospital, and he was placed in a series of foster homes. In 1946, at age 20, he went to prison for breaking and entering.

In prison, Malcolm X became a member of the Nation of Islam and after his parole in 1952 he quickly rose to become one of its leaders. For a dozen years Malcolm X was the public face of the controversial group, but disillusionment with Nation of Islam head Elijah Muhammad led him to leave the Nation in March 1964. After a period of travel in Africa and the Middle East, he returned to the United States, where he founded Muslim Mosque, Inc. and the Organization of Afro-American Unity. In February 1965, less than a year after leaving the Nation of Islam, he was assassinated by three members of the group.

 Martin Luther (help·info) (10 November 1483 – 18 February 1546) was a German monk, priest, professor of theology and iconic figure of the Protestant Reformation. He strongly disputed the claim that freedom from God's punishment for sin could be purchased with money. He confronted indulgence salesman Johann Tetzel with his Ninety-Five Theses in 1517. His refusal to retract all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the pope and condemnation as an outlaw by the Emperor.

Luther taught that salvation is not earned by good deeds but received only as a free gift of God's grace through faith in Jesus Christ as redeemer from sin. His theology challenged the authority of the Pope of the Roman Catholic Church by teaching that the Bible is the only source of divinely revealed knowledge and opposed sacerdotalism by considering all baptized Christians to be a holy priesthood. Those who identify with Luther's teachings are called Lutherans.
