In the Byzantine Empire, Christianity and the differing ideas about it caused great conflict. When the idea of religious icons came about, Emperor Leo Ill created Iconoclasm, which permitted the smashing of these religious icons. The events following the creation of Iconoclasm showed how distant the church was from the government. Eventually the quarrel led to the separation of the Catholic Church from the Eastern Christian Church, known as the Great Schism.

Empire, it is clear that in both societies, religion was always in opposition with the government. There were many factors that led to the decline of both the Roman and the Byzantine Empires. In Rome, the empire simply became too large. They had to resort to using mercenaries to defend their excess land, but they often rebelled against the government. The separation of the empire into east and west also proved to be detrimental to the empire.
The western side, the Romans, was defeated by Germanic barbarians who unseated their last emperor, a 14 year old boy, In AD 476.

Byzantium was also constantly faced with military challenges from outside Invaders, and the Great Schism eliminated any possibility of outside help. The Byzantines used a multitude of tactics to try to keep enemies away, but the empire eventually fell to the Ottoman Turks In 1453.
