In point of fact, however, that name was taken less than a century later than the death of John XXII by Baldassarre Cossa upon his election to the papacy as John XXIII on May 17, 1410. Thus, John joined the illustrious company of Rome's Gregory XII (1406-1415) and the Pope in Avignon, Benedict XIII (1394-1424). Infamous for his unscrupulousness and his ambition, Cossa was forced by the Council of Constance to abdicate on May 29, 1415, and he and Benedict were declared Anti-Popes. After a three year imprisonment in the Palatine, with his old enemy the Elector Ludwig III as his jailer, Cossa returned to Italy, where he threw himself on the mercy of Pope Martin V. He died as the Cardinal-Bishop of Tusculum on December 22, 1419.
