The Western Schism, also called Papal Schism, The Vatican Standoff, Great Occidental Schism and Schism of 1378, was a split within the Catholic Church lasting from 1378 to 1417 in which bishops residing in Rome and Avignon both claimed to be the true pope, joined by a third line of Pisan popes in 1409. The schism was driven by personalities and political allegiances, with the Avignon papacy being closely associated with the French monarchy. These rival claims to the papal throne damaged the prestige of the office.
