On March 5th, 1893, Peter Kropotkin—then the world’s most prominent anarchist—delivered a landmark lecture on “Anarchism” in London, raising funds for *Freedom*, the newspaper he co-founded in 1886. First serialized in *La Révolte* and later revised as a pamphlet, this powerful text remained unavailable in English—until now. Intended as an introduction to anarchism, Kropotkin’s lecture explores the movement’s roots, its critique of capitalism and the State, and its vision of a cooperative, anarchist-communist society. Emphasizing the role of working-class resistance, he writes with clarity and conviction, reminding us that revolution is both necessary and possible: “The expropriation of all wealth and the use of that wealth for a social purpose – that is the revolution.”
