EASTERN ROME EMPIRE / BYZANTINE

The transition from the "Old Rome" to the "Byzantine Empire" is one of history's most fascinating continuities. While the Western Roman Empire collapsed in 476, the Eastern half—centered in Constantinople—survived for another millennium, preserving Roman law, Greek culture, and Christian theology.

I. The "Fall" of the West (476)

In 476, the Germanic chieftain Odoacer deposed the boy-emperor Romulus Augustulus. To the people living in the East, this wasn't necessarily the "end" of Rome, but rather a loss of territory. The Eastern Emperor, Zeno, simply claimed to be the sole ruler of the entire Roman world, even if he couldn't exercise power in Italy.

II. Key Eras of the Byzantine Empire

The empire experienced a cyclical pattern of expansion, crisis, and cultural rebirth over nearly 1,000 years.

Era	Key Features	Major Figures
The Justinian Era (527–565)	The "Last of the Romans." Reconquered Italy and Africa. Built the Hagia Sophia and codified Roman law into the Corpus Juris Civilis.	Justinian I, Empress Theodora
The Heraclian Shift (610–717)	Transition from Latin to Greek as the official language. Emergence of the Theme System (military-administrative districts).	Heraclius
The Macedonian Renaissance (867–1056)	A "Golden Age." Regained the Balkans and parts of the East. Conversion of the Slavs to Orthodox Christianity.	Basil II ("The Bulgar-Slayer")
The Komnenian Recovery (1081–1185)	A period of military and financial stabilization despite the growing threat of the Seljuk Turks and the Crusades.	Alexios I Komnenos

III. Turning Points in Decline

• The Great Schism (1054): The formal break between the Roman Catholic and Eastern Orthodox Churches, which isolated Byzantium from Western European support.
• The Battle of Manzikert (1071): A catastrophic defeat against the Seljuk Turks that led to the permanent loss of the Anatolian heartland (modern Turkey).
• The Fourth Crusade (1204): Perhaps the greatest "betrayal." Western Crusaders, intended for Jerusalem, instead sacked Constantinople. The empire was partitioned and never fully recovered, though it was retaken by the Greeks in 1261.

IV. The Fall of Constantinople (1453)

By the mid-15th century, the "Empire" was reduced to little more than the city of Constantinople itself.

• The Siege: Sultan Mehmed II (the Conqueror) of the Ottoman Empire besieged the city for 55 days.
• Technology: The Ottomans used massive cannons (the "Superguns") to breach the legendary Theodosian Walls, which had stood for 1,000 years.
• The End: On May 29, 1453, the city fell. The last emperor, Constantine XI, died in the final street fighting.

V. The Legacy

When Constantinople fell, many Greek scholars fled to Italy, carrying ancient manuscripts with them. This influx of classical knowledge is often cited as a primary spark for the Italian Renaissance.

A Note : 

• The people of the empire never called themselves "Byzantines." They called themselves Rhomaioi (Romans) and their state the Roman Empire until the very end. The term "Byzantine" was coined by historians in the 16th century.
• The name Byzantine is taken from the name of the city called Byzantium, an ancient city on the Bosphorus Strait.
• Constantine I (306-337) gave the city of Byzantium a new name, "Constantinople", and made it the second capital of his empire after Rome.
• Constantine I (306-337) was the first Roman Emperor to embrace Christianity.
