Pope Gregory XI (, born Pierre Roger de Beaufort; c. 1329 – 27 March 1378) was head of the Catholic Church from 30 December 1370 to his death in March 1378. He was the seventh and last Avignon pope and the most recent French pope recognized by the modern Catholic Church. In 1377, Gregory XI returned the Papal court to Rome, ending nearly 70 years of papal residency in Avignon, France. His death shortly after was followed by the Western Schism involving two Avignon-based antipopes. Early life Pierre Roger de Beaufort was born at Maumont, France, around 1330. His uncle, Pierre Cardinal Roger, Archbishop of Rouen, was elected pope in 1342 and took the name Clement VI. Clement VI bestowed a number of benefices upon his nephew and in 1348, created the eighteen-year-old a cardinal deacon. The young cardinal attended the University of Perugia, where he became a skilled canonist and theologian. Conclave 1370 After the death of Pope Urban V (December 1370), eighteen cardinals assembled at Avignon entered the conclave on 29 December. Cardinal Roger was unanimously elected on 30 December. Though initially opposing his own election, Roger eventually accepted and took the name of Gregory XI. On 4 January 1371 he was ordained to the priesthood by the Dean of the College of Cardinals, Guy de Boulogne, and on 5 January was consecrated Bishop of Rome and crowned by the new protodeacon Rinaldo Orsini in the cathedral Notre Dame des Doms in Avignon. Papacy Immediately on his accession he attempted to reconcile the Kings of France and England, but failed. Gregory confirmed a treaty between Sicily and Naples at Villeneuve-lès-Avignon on 20 August 1372, which brought about a permanent settlement between the rival kingdoms, which were both papal fiefs. Gregory also tried to undertake a crusade due to pleas from Catherine of Siena in 1376 by continuing Pope Urban V’s call for Christians to stop fighting other Christians, which Urban called for in November of 1366. Efforts were also made to reform corrupt practices in the various monastic orders, such as collecting fees from persons visiting holy sites and the exhibiting of faux relics of saints. Many of these acts were through the persistence of letters from Catherine of Siena. Like the preceding popes of Avignon, Gregory XI made the fatal mistake of appointing Frenchmen, who did not understand the Italians and whom the Italians hated, as legates
