Pope John XXII, born Jacques Duèze in 1244, served as the head of the Catholic Church from August 7, 1316, until his death on December 4, 1334. He was the second and longest-reigning Avignon Pope, elected by the Conclave of Cardinals in Lyon. His papacy was marked by a centralization of power and wealth within the Church, mirroring the princely lifestyle of his predecessor, Clement V, while residing in Avignon.
Throughout his tenure, John XXII faced significant political challenges, notably opposing the policies of Holy Roman Emperor Louis IV the Bavarian. This opposition led to Louis's invasion of Italy and the establishment of an antipope, Nicholas V. Additionally, John XXII took a firm stance against the Franciscan interpretation of Christ's poverty, issuing multiple papal bulls to assert his views, which sparked criticism from theologians like William of Ockham.
One of the notable achievements of Pope John XXII was the canonization of Thomas Aquinas on July 18, 1323, following a rigorous three-year process. However, his sermons on the beatific vision stirred controversy, prompting him to retract his views shortly before his passing. John XXII's legacy is a complex interplay of theological debate and political maneuvering, reflecting the tumultuous nature of the Church during his reign.
