March 27, 1378 - Pope Gregory XI Dies

In the late 1300s and early 1400s, there were times at which three different men claimed to be the Pope at the same time. Because some of these men were stationed in Avignon, France, and not in Rome, it further complicated the situation. Pope Gregory XI was the last universally accepted of the French Avignon popes when he died on March 27, 1378.
