The Great Schism

One forbidden word added to a creed. A delegation that marched into the greatest church in Christendom and dropped an excommunication on the altar mid-service. A Crusader army that sacked a Christian city instead of fighting Muslims. The Great Schism of 1054 didn’t happen overnight. It built over centuries of cultural drift, political rivalry, and competing claims to authority — and its consequences still shape the world today.
