Watch VoirFilms. A re-enactment of the Jules Durand case. In 1910, Jean Jaurès [leader of the French socialist movement] took the lead in defending a working-class coal miner, Jules Durand, accused of complicity in and condemned to death for the murder of a labor leader. As in the Dreyfus Affair, a false dossier had been used to convict Durand. Jaurès argued that the memory of the Dreyfus Affair saved Durand, calling the case the working class’s Dreyfus Affair.
