Francisco Ferrer i Guàrdia was a radical freethinker, anarchist, and educationist behind a network of secular, private, libertarian schools in and around Barcelona. His execution, following a revolt in Barcelona, propelled Ferrer into martyrdom and grew an international movement of radicals and libertarians, who established schools in his model and promoted his schooling approach.
Ferrer was raised on a farm near Barcelona, where he developed republican and anti-clerical convictions. As a train conductor, he transmitted messages for the republican leader Manuel Ruiz Zorrilla, exiled in France. Following a failed republican uprising in 1885, Ferrer, too, moved to Paris with his family, where they stayed for 16 years. Ferrer began to explore anarchism and education. At the turn of the century, Ferrer had resolved to open a libertarian school modeled on Paul Robin's Prévost orphanage school. A large inheritance from a Parisian tutee provided the means to do so.
