Nonviolent resistance (or nonviolent action) is the practice of achieving goals through symbolic protests, civil disobedience, economic or political noncooperation, and other methods, without using violence. It is largely synonymous with civil resistance. Each of these terms ("nonviolent resistance" and "civil resistance") has its distinct merits and also slightly different connotations, which are briefly explored in the entry on civil resistance. The modern form of non-violent resistance was popularised and proven to be effective by the Indian leader Mahatma Gandhi in his efforts to gain independence from the British.

Nonviolent resistance advocates include Leo Tolstoy, Mohandas Gandhi, Andrei Sakharov, Martin Luther King, Jr, Václav Havel, Gene Sharp, and Lech Wałęsa. In 2006 peace ethologist Judith Hand presented a strategy for abolishing war premised on using nonviolent resistance (A Future Without War: the Strategy of a Warfare Transition).

From 1966 to 1999 nonviolent civic resistance has played a critical role in 50 of 67 transitions from authoritarianism. Recently, nonviolent resistance has led to the Rose Revolution in Georgia and the Orange Revolution in Ukraine. Current nonviolent resistance includes the Jeans Revolution in Belarus, the "Jasmine" Revolution in Tunisia, and the fight of the Cuban dissidents.

 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.
