Question

Why was it essential for Byzantine Emperors to legitimize their authority through the Church?

Answer 1

Answer:

The Byzantine Empire, also referred to as the Eastern Roman Empire, or Byzantium, was the continuation of the Roman Empire in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern Istanbul, formerly Byzantium).

Caesaropapism's chief example is the authority that the Byzantine (East Roman) Emperors had over the Church of Constantinople and Eastern Christianity from the 330 consecration of Constantinople through the tenth century.
