Pope Gregory XI (Latin: Gregorius 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. In 1377, Gregory XI returned the papal court to Rome, ending nearly 70 years of papal residency in Avignon, in modern-day France. His death was swiftly followed by the Western Schism involving two Avignon-based antipopes. Source: Wikipedia (en)
