The Byzantine Empire

Eastern Christian Empire - One God, One Empire, One Religion

The Eastern Empire

As Western Europe succumbed to the Germanic invasions, imperial power shifted to the Byzantine Empire (the eastern part of the Roman Empire).

Constantinople

Constantinople became the sole capitol of the empire and remained so until the successful revival of the western empire in the 8th century by Charlemagne.

The Empire at Its Height

The empire was at its height In 565, during Justinian’s reign. It included most of the lands surrounding the Mediterranean Sea.

Extensive Building Plans

Justinian was an ambitious builder. His greatest monument was the magnificent domed church of Hagia Sophia (Holy Wisdom), which was constructed in just five years (532 37).

Decline in the 7th Century

In the seventh century the empire lost Syria, the Holy Land, Egypt, and North Africa to invading Islamic armies.

First Fall of Constantinople

in 1204, the Crusaders attacked, conquered, and pillaged the city of Constantinople, a goal that the Muslims had been trying achieve for centuries

Recovery of Territory

The Byzantines called upon the European states to push back the Muslim conquerors. The European states complied, successfully pushed back the Seljuks, returned territory to the Byzantines, and carved out kingdoms of their own in Syria and Palestine.

Fall of Constantinople

In 1451, 19 year old new Sultan Mehmed (Muhammed) II set out to prove himself by conquering Constantinople and all of Asia Minor and Balkans once and for all. Key to successful siege was ability to breach massive 3.5 mile long Theodosian wall with its moats, towers and triple layered walls that held out invaders for over a millennium!

Contribution to Western Civilization

Throughout the early Middle Ages, the Byzantine Empire remained a protective barrier between western Europe and hostile Persian, Arab, and Turkish armies.The Byzantines were also a major conduit of classical learning and science into the West down to the Renaissance. While western Europeans were fumbling to create a culture of their own, the cities of the Byzantine Empire provided them a model of a civilized society.
