"Pope Gregory XI (Latin: Gregorius; c. 1329 – 27 March 1378) was Pope from 30 December 1370 to his death in 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, France. His death shortly after was followed by the Western Schism involving two Avignon-based antipopes." - (en.wikipedia.org 31.01.2020)
