Hello!
The Western Schism lasted from 1378 to 1417 and was a split from within the Roman Catholic Church. Basically what happened was three popes thought that they were the "true" pope so eventually they split apart. The schism was ended by the Council of Constance on 1414 and lasted 4 years fro the debate to finally end on 1418.
I hope it helps!
