Answer:
Great schism of 1378
France
Step-by-step explanation:
As the effects of the plague started wearing off, the Catholic Church was divided, which led to the Great Schism of 1378. The Schism involved the emergence of religious and political differences which caused issues.
During this time, the seat of power moved from Rome, Italy, to France. The Italians had a difficult time accepting a new pope which led to them electing a new Roman pope instead.
