Summary
Highlights
The Byzantine Empire, the eastern half of the Roman Empire, outlived its western counterpart by nearly a millennium. Originally named Byzantium, Emperor Constantine the Great renamed it Constantinople in 330 AD and made it the capital. Constantine legalized Christianity, and Emperor Theodosius I later made it the official state religion.
The reign of Justinian the Great is considered the 'Golden Age of Byzantium'. He reconquered much of the lost Western Roman Empire, implemented a unified legal code that influenced future European law, and oversaw the construction of significant monuments like the Hagia Sophia. His wife, Theodora, played a crucial role in legal reforms, particularly for women's rights.
Following Justinian, the empire faced continuous wars with Persian forces. Emperor Heraclius led Byzantium to victory, restructured the military, adopted Greek as the official language, and developed the 'theme system' for defense. However, the rise of Muslim Arab armies led to the loss of rich provinces like Egypt and Syria, transforming the empire into a predominantly agrarian, Greek-speaking society. The Isaurian Dynasty saw the rise of Iconoclasm, creating further conflict with the Western Church.
From the 8th to the 11th century, under the Macedonian Dynasty, the Byzantine Empire experienced another Golden Age, marked by advancements in art, increased trade control, and international prestige. However, growing tensions between the East and West culminated in the 'Great Schism' of 1054, dividing Christianity into the Roman Catholic and Eastern Orthodox Churches.
Invasions by the Seljuk Turks and Latin armies, including the damaging Fourth Crusade which saw the sacking of Constantinople, severely weakened the empire. Economically crippled under the Palaiologan emperors, Byzantium eventually fell to the Ottoman Turks in 1453 with the breach of Constantinople's walls.
Despite its fall, the Byzantine Empire left a significant legacy, influencing countries that practiced its Eastern Orthodox religion. Crucially, its libraries safeguarded ancient Greek and Roman texts, preventing their loss and providing the foundational knowledge for the Renaissance in Western Europe.
