Byzantine Empire

Overview

The Byzantine Empire was the medieval continuation of the Roman Empire centered on Constantinople, enduring for over a millennium from the city's dedication in 330 until its fall to the Ottomans in 1453. In the African context it is the successor phase to the Eastern Roman Empire: after the Arab conquests of the 630s–640s took Syria and Egypt, and the fall of Carthage in 698 ended Roman Africa, the empire survived as a predominantly Greek-speaking, Orthodox Christian power in Anatolia and the Balkans — while continuing to claim, and intermittently exercise, authority around the Mediterranean, including the Arab–Byzantine condominium over Cyprus and the reconquest of Crete in 961.

History

The post-633 empire passed through dramatic cycles. Leo III (r. 717–741) repelled the great Arab siege of Constantinople and reorganized the empire into military themes; the iconoclast controversies roiled the 8th–9th centuries until icons were permanently restored in 843. The Macedonian dynasty (867–1056) brought a renaissance: emperors like Nikephoros II, John Tzimiskes, and Basil II (r. 976–1025) reconquered Crete, Cilicia, Antioch, and Bulgaria, pushing the empire to its medieval apex of some 1.6 million km². Constantinople, Europe's largest and wealthiest city, minted the gold solidus, patronized scholars, and gave the world Greek fire, Byzantine law (the Basilika), and dazzling mosaic art. But the defeat at Manzikert in 1071 opened Anatolia to the Seljuk Turks, and the Komnenian restoration (1081–1180) only temporarily recovered it — Alexios I's appeal to the Pope inadvertently launched the Crusades.

The catastrophe came in 1204, when the Fourth Crusade sacked Constantinople and carved the empire into Latin and Greek successor states. Michael VIII Palaiologos restored the empire in 1261, but it was now a regional power, drained by civil wars and hemmed in by the rising Ottomans, who took the Balkans and Anatolia piecemeal. On 29 May 1453 Mehmed II captured Constantinople; the last emperor, Constantine XI, died fighting, and the Roman story of over two millennia ended.

Decline and legacy

The Byzantine legacy is immense: it preserved and transmitted classical Greek and Roman learning, shaped Eastern Orthodox Christianity and Slavic literacy (Cyrillic script), and its diplomacy, law, and art influenced both the Islamic world and Renaissance Europe. In Africa specifically, its centuries of rule left monuments from Carthage to Cyprus, and its fall reshaped the Mediterranean balance for centuries.
