Since Pope Clement V in 1309 - entangled in the power political intrigues of the French king - had moved his residence in Avignon, France, heard the calls: "Back to Rome!" The successor of Peter should live where Peter, his great predecessor, once died. The campaign against the "whore and metze Avignon" (Petrarch) began to develop into a public problem for the papacy. Urban V. (1362-1370) was the first to make concrete return chances. Urban was a native Frenchman and visited Rome twice. But twice he also returned to his southern French office. When he wanted to leave the city on the Tiber in September 1370, Saint Birgitta prophesied an early death for him. When he arrived in Avignon, Urban actually died. Urban's successor was his nephew, also Frenchman. And yet it was he who was to lead the Curia back after 70 years. Gregory XI. The growing sentiment for Rome in large parts of the church people was just as true as the strong faction in the church leadership for remaining in France. He first decided to travel to Rome like his predecessor. On September 13, 1376 he set out, a good four months later, he held with 13 cardinals solemn entry into Rome and took his seat in the Vatican. Who knows, maybe Gregor also wanted to stay only temporarily, but this time the death came even more punctually: In March 1378 Gregory died in Rome, and the Vatican was again the papal residence.
