Pope John XXII (; 1244 – 4 December 1334), born
Jacques Duèze (or
d'Euse), was
Pope from 7 August 1316 to his death in 1334. He was the second
Avignon Pope, elected by a
conclave in
Lyon assembled by
King Louis X's brother Philip, the Count of Poitiers, later King
Philip V of France. Like his predecessor,
Clement V, he centralized power and income in the Papacy and lived a princely life in
Avignon. He opposed the political policies of
Louis IV of Bavaria as
Holy Roman Emperor, which prompted Louis to invade Italy and set up an antipope,
Nicholas V. Pope John XXII faced controversy in theology involving his views on the
Beatific Vision, and he opposed the Franciscan understanding of the poverty of Christ and his apostles. He canonized
St. Thomas Aquinas.
