The Western Schism divided Christianity first between two, then three, popes. Clement VII lived at Avignon in France, Urban VI in Rome. Vincent was convinced the election of Urban was invalid though Catherine of Siena (April 29) was just as devoted a supporter of the Roman pope. In the service of Cardinal de Luna, Vincent worked to persuade Spaniards to follow Clement. When Clement died, Cardinal de Luna was elected at Avignon and became Benedict XIII.
