Peter Kropotkin (1842?1921) was the foremost theorist of the anarchist movement and was imprisoned for his activism in Russia and France. Born a Russian prince, he rejected his title to become a revolutionary, seeking a society based on freedom, equality, and solidarity. His writings include The Conquest of Bread; Fields, Factories, and Workshops; Anarchism, Anarchist-Communism, and the State; Memoirs of a Revolutionist; and Modern Science and Anarchism. New editions of his classic works Mutual Aid: A Factor of Evolution; Words of a Rebel; and The Great French Revolution, 1789?1793 were published by PM Press to commemorate his life and work on the centennial of his death.
