Cardinal Robert of Geneva is elected as Pope Clement VII, beginning the Papal schism.

Robert of Geneva was elected to the papacy as Clement VII by the cardinals who opposed Pope Urban VI and was the first antipope residing in Avignon, France. His election led to the Western Schism.

The Western Schism, also known as the Papal Schism, the Great Occidental Schism, the Schism of 1378, or the Great Schism, was a split within the Catholic Church lasting from 20 September 1378 to 11 November 1417, in which bishops residing in Rome and Avignon simultaneously claimed to be the true pope, and were eventually joined by a line of Pisan claimants in 1409. The event was driven by international rivalries, personalities and political allegiances, with the Avignon Papacy in particular being closely tied to the French monarchy.
