From Chalcedon to the Arab invasion of Egypt
Copts suffered under the rule of the Byzantine Eastern Roman Empire. The Melkite Patriarchs, appointed by the emperors as both spiritual leaders and civil governors, massacred the Egyptian population whom they considered heretics. Many Egyptians were tortured and martyred to accept the terms of Chalcedon, but Egyptians remained loyal to the faith of their fathers and to the Cyrillian view of Christology. One of the most renowned Egyptian saints of that period is Saint Samuel the Confessor.
