During the early 6th century, people living in Italy would have thought the Ostrogothic kingdom was the carrier of Roman ideologies. Within a few decades, this kingdom came to a violent end at the hands of the Eastern Roman Empire, the half of the Roman Empire that had continued after the end of the Empire in the West. (See Chapter 5.) We usually refer to this empire as the Byzantine Empire or Byzantium.

The inhabitants and rulers of this Empire did not call themselves Byzantines, but rather referred to themselves as Romans. After all, this empire was a continuation of the Roman state. Modern historians call it the Byzantine Empire in order to distinguish it from the Roman Empire that dominated the Mediterranean world from the first through fifth centuries. The capital of this kingdom had been Constantinople.
By the beginning of the sixth century, the Byzantine Army was the most lethal army to be found outside of China. In the late fifth century, the Byzantine emperors had built up an army capable of dealing with the threat of both Hunnic invaders and the Sassanids, a dynasty of aggressively expansionist kings who had seized control of Persia in the third century. Soon, this army would turn against the Ostrogothic kingdom of Italy.
Emperor Justinian (r. 527 – 565) would destroy the Ostrogrothic and Vandal kingdoms. He was not an aristocracy, but rather came from the army. He learned about emperorship from his uncle, the emperor Justin I (r. 518 – 527).
As a leader, he influenced art and architecture. The centerpiece of his building campaign was the church called Hagia Sophia, Greek for “Divine Wisdom.” Located in the central position of the city of Constantinople, the placement was meant to demonstrate the close relationship between the Byzantine state and the Church that legitimated that state. The Hagia Sophia would be the principal church of the Eastern Empire for the next thousand years, and it would go on to inspire countless imitations.
This Church was the largest building in Europe. Its domed roof was one hundred and sixty feet in height, and, supported by four arches one hundred and twenty feet high. The interior of the church was burnished with gold, gems, and marble. Even a work as magnificent as the Hagia Sophia, though, showed a changed world: it was produced with mortar rather than concrete, the technology for the making of which had already been forgotten.

While Justinian’s efforts as a lawmaker showed the secular side of his authority. Under his direction, the jurist Tribonian took the previous 900 years’ worth of Roman Law and systematized it into a text known as the Body of Civil Law or the Justinian Code. This law code would go on to serve as the foundation of European law, and much of the world’s law as well.
As Byzantine emperor (and thus Roman emperor), Justinian would have regarded his rule as universal, so he sought to re-establish the authority of the Empire in Western Europe. In addition, both Vandal Carthage and Ostrogoth Italy were ruled by peoples who were Arians, regarded as heretics by a Catholic emperor like Justinian.
During a dispute over the throne in the Vandal kingdom, the reigning monarch was overthrown and had fled to the Eastern Empire for help and protection. In 533, Justinian sent his commander Belisarius to the west. In less than a year, the capable general had defeated the Vandals, destroyed their kingdom, and brought North Africa back into the Roman Empire. Justinian then turned his sights on a greater prize: Italy, home of the city of Rome itself, which still held a place of honor and prestige.
In 535, the Roman general Belisarius crossed into Italy. Unfortunately, the Ostrogothic kingdom put up a more robust fight than had the Vandals in North Africa. It took the Byzantine army nearly two decades to destroy the Ostrogothic kingdom and return Italy to the rule of the Roman Empire. In that time, Italy itself was irrevocably damaged. The city of Rome had suffered through numerous sieges and sacks. By the time it was fully in the hands of Justinian’s troops, the fountains that had provided drinking water for a city of millions were choked with rubble, the aqueducts that had supplied them smashed. The great architecture of the city lay in ruins, and the population had shrunk drastically.

6.3.1: The Aftermath of Justinian
Justinian’s reconquest of Italy would prove to be short-lived. Less than a decade after restoring Italy to Roman rule, the Lombards, another Germanic people, invaded Italy. Although the city of Rome itself and the southern part of the peninsula remained under the rule of the Byzantine Empire, much of northern and central Italy was ruled either by Lombard kings or other petty nobles.
But war was only one catastrophe to trouble Western Europe. For reasons that are poorly understood even today, the long-range trade networks across the Mediterranean Sea gradually shrank over the sixth and seventh centuries. Instead of traveling across the Mediterranean, wine, grain, and pottery were increasingly sold in local markets. Only luxury goods—always a tiny minority of most trade—remained traded over long distances.
Nor was even the heartland of Justinian’s empire safe from external threat. The emperor Heraclius (r. 610 – 641) came to power in the midst of an invasion of the Empire by the Sassanid Persians, who, under their king Khusrau (see Chapter Eight), threatened the Empire’s very existence. Indeed, his armies came within striking range of Constantinople itself. Moreover, Persian armies had seized control of Egypt and the Levant, which they would hold for over a decade. Heraclius launched a counter-attack into the heart of the Persian Empire that resulted in a Byzantine victory. No sooner had the Empire repelled one threat than another appeared.
Under the influence of the Prophet Muhammad, the tribes of the Arabian deserts had been united the caliphs and the Islam religion founded by Muhammad. Under the vigorous leadership of the first caliphs, Arab Muslim armies invaded both Sassanid Persia and the Byzantine Empire. In 636, at the Battle of Yarmouk, the Byzantine field army was badly beaten. In the aftermath, Syria, Palestine, and then Egypt fell from Christian Byzantine rule to the cultural and political influence of Islam.
The seventh-century also saw invasions by various semi-nomadic peoples into the Balkans, the region between the Greek Peloponnese and the Danube River. Among these peoples were the Turkic Bulgars, the Avars (who historians think might have been Turkic), as well as various peoples known as Slavs. The Avars remained nomads on the plains of central Europe, but both Bulgars and Slavs settled in Balkan territories that no longer fell under the rule of the Byzantine state. Within a generation, the Empire had lost control of the Balkans as well as Egypt, territory comprising an immense source of wealth in both agriculture and trade. By the end of the seventh century, the Empire was a shadow of its former self.
Indeed, the Byzantine Empire faced many of the social and cultural challenges that Western Europe did, although continuity with the Roman state remained. In many cases, the cities of the Byzantine Empire shrank nearly as drastically as did the cities of Western Europe. Under the threat of invasion, many communities moved to smaller settlements on more easily defended hilltops. The great metropolises of Constantinople and Thessalonica remained centers of urban life and activity, but throughout much of the Empire, life became overwhelmingly rural.
Even more basic elements of a complex society, such as literacy and a cash economy, went into decline. The Byzantine state issued less money and most transactions ceased to be in cash at this time. The economy was demonetized. Even literacy rates shrank. As in the west, literacy increasingly became the preserve of the religious.
