The rise and fall of the Byzantine Empire

Rise and fall of the Byzantine Empire in 60 seconds

In 330 CE, Emperor Constantine made the bold move of shifting the Roman capital to Byzantium and renaming it Constantinople. This decision helped shape the Eastern Roman Empire, or what we now call the Byzantine Empire. Here’s how the city rose to global prominence, and why its legacy lingers today.

The top 10 Byzantine emperors

"The History of Byzantium" podcast, hosted by Robin Pierson, tells the entire history of the Byzantine Empire, from Constantine to the fall of Constantinople. As of this writing, it isn’t quite done, but there are more than 300 episodes to peruse. The episode linked here, with guest Anthony Kaldellis, ranks the top 10 Byzantine emperors.

Being a Byzantine emperor

The Byzantium and Friends podcast, hosted by Anthony Kaldellis, surveys current research in the history of the Byzantine Empire and its neighbors. In each episode, Professor Kaldellis interviews a scholar about their recent work. The cumulative effect is to reveal a world much more complex, and much more interesting, than the Byzantium found in traditional surveys. The linked episode considers the perks and pitfalls of being a Byzantine emperor.

The underground cities of the Byzantine Empire

This TED-Ed video explores the mysterious cave cities of Cappadocia. Although their oldest sections may go back to the Bronze Age, most of these subterranean complexes were excavated during the Byzantine period, when the locals went underground to take shelter from Arab raiders. Monasteries were also cut into pinnacles of the local tufa, and decorated with frescoes that have often survived to the present.

Hagia Sophia, Istanbul's most famous and controversial landmark

A short video about the iconic Byzantine church. Still Istanbul’s most famous and, since its reconversion to a mosque, most controversial building. The recognizable dome has partially collapsed several times over the centuries, but remains a marvel of engineering. The mosaics, though fragmentary, are among the finest ever created and trace both the gradual evolution and the remarkable continuity of Byzantine art.

The mosaics of San Vitale, Italy's Byzantine city

This video explores the unique artistic heritage of Ravenna, the center of Byzantine power in Italy. The city’s churches and baptistries still sparkle with a dazzling array of Byzantine mosaics. The most famous of these, in the Church of San Vitale, show Justinian and his wife Theodora with their courtiers. A visit to Ravenna – or at least a look at this video – is highly recommended to anyone interested in Byzantine history or art.

Visualizing Byzantium in the year 1200

This is a computer reconstruction of the Byzantine capital at its apogee, just before the Fourth Crusade. Alongside detailed renderings of the Hippodrome and Hagia Sophia, it includes dozens of the imperial city’s less famous monuments, many of which can still be found in modern Istanbul. The reconstruction is a work in progress, and the Byzantium 1200 X account routinely posts updates.

A map of the Byzantine Empire

This map, hosted on the World History Encyclopedia, shows the Byzantine Empire in four eras. The area shaded dark purple is the original Eastern Roman Empire.

The western Roman Empire fell in the 5th century CE amid invasions, weakness

The unusual connection between Venice and Byzantium

This article explores the complicated relationship between Venice and the Byzantine Empire. Venice grew up in the shadow of Byzantium, serving as a trade partner and faithful ally for centuries. Gradually, relations grew hostile, and Venetian ships would carry the Fourth Crusade to its fateful rendezvous with Constantinople. Visitors to San Marco can still see marble and porphyry from Constantinople, built into the walls of Venice’s preeminent church.

The impressive walls of Constantinople

This video explores the land walls of Constantinople, built on the orders of Theodosius II in the mid-fifth century. They consisted of a triple line of defenses, studded with hundreds of towers and supplemented with a moat. The walls were besieged dozens of times, but were only broken in 1453 by the power of Ottoman cannons. As repaired by the Ottomans, the walls are still largely intact today.

How Byzantine scholars supercharged Renaissance Italy

A brief survey of how Byzantine scholars changed the course of the Renaissance by introducing Classical Greek literature to Italy.

How the Code of Justinian formed the basis of modern law

This video explores the significance of Justinian’s Corpus Juris Civilis. The most important component of the Corpus, the Digest, collected the opinions of eminent Roman jurists.

The rise of ISIS, explained in 6 minutes

The final war between the Persian and Byzantine empires

The Arab conquests of the seventh century, which swept over Egypt, Syria, and Mesopotamia, were made possible by a catastrophic generation-long war between the Byzantine and Persian Empires. That war, in turn, was the last act in a struggle that had gone on for centuries, and shaped the whole subsequent history of the Middle East.

The Chora Church, the height of Byzantine art

The Palaeologan Renaissance took place in the final centuries of Byzantium, and in the face of steep political and economic decline. Perhaps the movement’s most famous artistic product is the Chora Church in Istanbul. Renovated in the early fourteenth century by Theodore Metochites, a learned court official, the church features remarkably vibrant mosaics and frescoes. Although the building was recently reconverted into a mosque, most of its decorations are still visible.

Exploring the Hippodrome of Constantinople

The Hippodrome had room for about 80,000 spectators (more than the Colosseum, but less than Rome’s Circus Maximus). It was simultaneously Constantinople’s premier entertainment venue and its greatest political theater: the emperor routinely watched the games, and sometimes communicated with the crowd through a herald. The worst riot in Byzantine history, the Nika Revolt, began when the factions of the Hippodrome united in opposition to Justinian.

The century-long debate over religious images in Byzantium

The iconoclast controversy, which tore Byzantium apart in the eighth and ninth centuries, centered on the use of sacred images (or icons) in Christian worship. The Iconoclasts (literally, “icon smashers”) regarded sacred images as sacrilegious; their opponents, the Iconophiles (“icon lovers”), defended icons as aids to personal devotion. After decades of struggle, the Iconophiles prevailed; their victory ensured that icons, and the brilliant mosaics inspired by them, remained a feature of Byzantine churches.

A medieval Italian visits Constantinople

In the tenth century, the Holy Roman Emperor Otto I sent Liudprand of Cremona, an Italian bishop, to Constantinople on a diplomatic mission. He was not successful. But the very undiplomatic report he sent back to the emperor about his experiences provides a unique – and often very entertaining – look at life and ceremony in the Byzantine capital, dramatically different from anything in Liudprand’s Italy.
