The World of Byzantium
Overview
About
01: Imperial Crisis and Reform
A century of crisis between 193 CE and 305 CE propelled the Roman world out of the classical into the early medieval age. After 235 CE, a series of civil wars and invasions shattered the peace of the 60-million-subject Empire, profoundly changed all aspects of life, and set the stage for the rise of the civilization that would be known as Byzantium.
02: Constantine
Convinced that the Christian God had given him a signal victory, Constantine (r. 306–337) embraced the new faith and pointed the Empire in new directions. His sponsorship of the First Ecumenical Council of Nicaea (325) and his decision to build a "New Rome" on the strategic Bosporus laid the foundations of Byzantium.
03: State and Society Under the Dominate
Abandoning republican fictions, emperors after the 3rd century CE ruled as autocrats. Imperial demands eroded civic life and put classical religion and civilization in jeopardy. As the 5th century dawned, the bonds that had tied local elites to Rome had loosened, and in the West the outlines of medieval localism were emerging.
04: Imperial Rome and the Barbarians
Citizen legions had long guarded Rome's frontiers. But after 235, emperors increasingly recruited barbarian tribal fighters under native leaders, thereby creating the very forces that would topple imperial power in the West.
05: The Rise of Christianity
Until the conversion of Constantine, Christians remained relatively few in number, mostly in Mediterranean cities. But Christian self-definition was well-honed by 312, putting Christian emperors and bishops into a position to reshape a classical world whose people mostly remained pagans into the 5th century.
06: Imperial Church and Christian Dogma
The Council of Nicaea in 325 endorsed the Trinitarian theology of Athanasius but did not settle all debate. Later councils at Ephesus (431) and Chalcedon (451) condemned Nestorians and Monophyistes, respectively. Emperors would continue striving to reconcile the latter, who commanded loyalty in the crucial provinces of Egypt, Syria, and eastern Anatolia.
07: The Friends of God—Ascetics and Monks
Solitary anchorites of the Egyptian desert inspired the 4th-century ascetic movement that led to medieval monasticism. St. Basil of Caesarea (330–379) penned rules regulating monastic life. His Latin counterpart, St. Benedict of Nursia (480–543), followed suit four generations later. Monasteries would play a decisive role in civilizing and converting Europe.
08: The Fall of the Western Empire
By 425, the western portion of the Roman Empire had shrunk to its Mediterranean core. The eastern court, secure behind Constantinople's Theodosian Walls, defied barbarian invaders, paid off Attila, and reformed its army. But it was too late to save the West, whose fall is usually dated to the deposition of Emperor Romulus Augustus by Odoacer in 476.
09: The Age of Justinian
Justinian (r. 527–565) was a cultured visionary, tireless public servant, and the last of the great Roman emperors. His supporting cast, headed by his wife Theodora (a former courtesan) and his superb general Belisarius, was similarly brilliant.
10: The Reconquest of the West
Justinian knew he could not afford long wars, but felt he had to fight the Arian German kingdoms in Italy, the Vandals in Africa, and the Persians to his east. Commanding small, often-outnumbered armies, both Belisarius and Narses (the eunuch general) worked military wonders, though the former was driven from command by the emperor's distrust.
11: The Search for Religious Unity
Well schooled in theology, Justinian believed that a common creed could unite Chalcedonians and Monophysites. But he failed to reckon with the depth of the disagreements among Rome, Constantinople, and Alexandria. Despite all his efforts, the imperial church at the end of his reign was even more bitterly divided than before.
12: The Birth of Christian Aesthetics and Letters
Justinian presided over the synthesis of Jewish, classical, and provincial arts into a Christian art and architecture that shaped medieval aesthetics and created such glories as the church mosaics of Ravenna and the magnificent dome of the Hagia Sophia. This lecture also contains a fascinating discussion of the origins and design features of basilicas and other Christian church buildings in the Eastern Empire.
13: The Emperor Heraclius
Heraclius (r. 610–641), the next great emperor after Justinian, managed to tame the Persian threat and restore the empire's fortunes on other fronts as well. But as Heraclius lay dying, his achievement was being nullified by the might of Arab horsemen and their powerful new faith, Islam.
14: The Christian Citadel
For more than two centuries, the heirs of Heraclius battled Lombards in Italy, Slavs and Bulgars in the Balkans, and Arabs in Anatolia. At the Battle of Poson (863), imperial forces won a victory that made it possible to carry Christianity and the civilized arts to the peoples of Eastern Europe. In the crucible of these wars was born the Byzantine Empire: Roman in government, Orthodox in faith, and Hellenic in language.
15: Life in the Byzantine Dark Age
Emperors of the "Dark Age" cracked down on corruption, and Constantinople fueled economic recovery by offering ready markets, but war and plague led to a demographic collapse by 700. Desperate imperial officials settled Slavs, Armenians, and Christian sectarians as soldiers or peasants, sponsored trade, and regulated prices. In response to crisis, emperors and subjects heroically reformed their world.
16: The Iconoclastic Controversy
Many Byzantines became convinced that icons meant idolatry, and hence divine punishment. Iconoclasm ("the breaking of images") began under Leo III (r. 717–741) and was finally settled by a moderate compromise in 843. The dispute defined orthodox ritual and widened the divide between the Catholic and Orthodox churches. Henceforth, Rome looked west and Constantinople became the "queen of cities" for Eastern Europe.
17: Recovery Under the Macedonian Emperors
The illiterate usurper Basil the Macedonian (867–886) and his heirs sought legitimacy via military victory and patronage of the arts. They could not have acted more opportunely. The 10th century was an era of battles won and peoples baptized, including the Varangians of Russia and the South Slavs. By 1025, Eastern Europe had taken on its early shape as a Byzantine Orthodox commonwealth—Slavic in speech, Byzantine in aesthetics, and imperial in institutions.
18: Imperial Zenith—Basil II
Basil II—nicknamed "The Bulgar-Slayer"—was the greatest warrior of his age. Scorning imperial ceremony and ruling in splendid isolation with Varangian mercenary guards, he crushed rebellions and annexed Armenia, Georgia, and Bulgaria. But Basil left no heir, and his very success had created a false sense of security among his inept successors. Once again, the Byzantine Empire was headed for crisis.
19: Imperial Collapse
How did the Byzantine state, which Basil II had left in perhaps its strongest position since the days of Justinian, so quickly become enfeebled and exposed to new invaders both east and west? In 1071, on the distant Armenian battlefield of Manzikert, Byzantine forces facing the Seljuk Turks suffered a staggering defeat that changed world history.
20: Alexius I and the First Crusade
Alexius, committed to reversing the verdict of Manzikert by reconquering Anatolia, asked Western princes to send him knights. Pope Urban II took this appeal for mercenaries as a summons to liberate the Holy Land, unleashing the Crusades and the eventual ruin of Byzantium.
21: Comnenian Emperors and Crusaders
When the Crusades of the 12th century ended in failure, Westerners blamed Byzantine treachery rather than their own poor logistics and strategy. Distracted by the Crusades, meanwhile, Constantinople neglected the Seljuk threat and lost to the Turks again at Myriocephalon (1176). The fecklessness of a new and weak dynasty, the Angelans, left Byzantium's great capital vulnerable to Crusader assault.
22: Imperial Exile and Restoration
In April 1204, members of the Fourth Crusade sacked Constantinople. Crusader barons and Byzantine generals carved out pieces of the faltering Empire. Michael VIII Palaeologus (1258–1282) eventually retook Constantinople, but neither he nor his less-than-brilliant heirs could reverse Byzantium's loss of even regional power or status.
23: Byzantine Letters and Aesthetics
Guardians of the classical heritage, Byzantine scholars saved many priceless Greek texts. From the 10th century on, emperors endowed schools and promoted intellectual life. Byzantine authors wrote in the tradition of Thucydides and Plutarch, and Photius revived the study of Plato. The mannerist church frescoes of the Byzantine 14th century compare with the best of contemporary Italian art, and exercised considerable influence on the Italian Renaissance.
24: The Fall of Constantinople
The Palaeologan emperors hoped to preserve their shrunken realm with Western aid but could not stop the Ottomans. The last emperor, Constantine XI, and his 7,000 gallant comrades went down fighting as the historic capital of the Christian East fell to the guns and bigger battalions of Sultan Mehmet II in May 1453. From the ashes of Constantinople, Mehmet built Istanbul, seat of a new Islamic empire that would last through World War I.
