Answer:
a lot happened
Explanation:
The Great Schism split the main faction of Christianity into two divisions, Roman Catholic and Eastern Orthodox. On July 16, 1054, Patriarch of Constantinople Michael Cerularius was excommunicated from the Christian church based in Rome, Italy. The Great Schism permanently divided the eastern Byzantine Christian Church and the western Roman Catholic Church. The popes in Rome claimed papal supremacy, while the leaders in the East rejected the claim. This led to western popes and eastern patriarchs excommunicating each other.  During that time, three men simultaneously claimed to be the true pope. Driven by politics rather than any theological disagreement, the schism was ended by the Council of Constance (1414–1418). For a time these rival claims to the papal throne damaged the reputation of the office.
