Pope Gregory XII: life, pontificate and role in ending the Western Schism

Ecclesiastical career and offices

Before becoming pope, Angelo Correr held a sequence of high ecclesiastical posts. He was appointed Bishop of Castello in 1380 and later received the honorary title of titular Patriarch of Constantinople in 1390. In 1405 he was raised to the College of Cardinals, and a year later he was elected pontiff. Key dates in his career are often listed to show the progression:

• 1380 – Bishop of Castello
• 1390 – Titular Patriarch of Constantinople
• 1405 – Made a cardinal
• 1406 – Elected Pope Gregory XII

Pontificate and the Western Schism

Gregory XII's reign coincided with competing papal obediences based in Rome and Avignon, and later a third group from Pisa. These rivalries produced diplomatic, theological and political complications across Christendom. As pope he remained the recognized pontiff by many European rulers, yet the existence of other claimants weakened centralized authority and complicated Church governance. His papacy mixed pastoral duties with efforts to negotiate among factions.

Resignation and the Council of Constance

In 1414–1418 the Council of Constance convened to end the schism and reform the church. Gregory XII agreed to send representatives to the council and ultimately to resign in order to allow a single, universally recognized pontiff to be chosen. He formally resigned in 1415, a rare voluntary renunciation of the papal office that was accepted as valid by the council. The council subsequently deposed or received the resignations of the other claimants and elected Pope Martin V in 1417, effectively restoring unity.

Death and legacy

After his resignation, Gregory XII retired to Italy and died at Recanati on 18 October 1417. His willingness to step down for the sake of unity has been highlighted in histories of the papacy; his resignation remained the last papal abdication until Pope Benedict XVI's resignation in 2013. Scholars note his role as a transitional figure whose actions helped to bring a turbulent chapter of medieval Church history to a close.
