The Aftermath of Justinian

The aftermath of Justinian’s reign marked a turning point in Byzantine history, characterized by both the enduring legacy of his ambitious reforms and the decline that followed his death. While his codification of Roman law and monumental building projects, such as Hagia Sophia, solidified his reputation as a transformative ruler, the empire struggled to maintain the vast territories he had reconquered. Successive rulers faced economic strain, military overextension, and the devastating impact of the plague. The period after Justinian’s death in 565 CE thus represents a complex era of transition — from imperial grandeur to gradual contraction — setting the stage for the medieval Byzantine state.

The Aftermath of Justinian

Introduction

The death of Emperor Justinian I in 565 CE ushered in a new and challenging phase for the Byzantine Empire. His reign had been one of great ambition—marked by extensive military conquests, monumental architecture, and comprehensive legal reforms—but the empire he left behind was strained by the weight of those very achievements. The decades following Justinian’s rule saw mounting economic hardship, depopulation from the plague, and renewed threats from both east and west. Territories that had been reconquered at great cost began to slip away, while internal divisions and external pressures tested the resilience of the Byzantine state. Yet amid these trials, the institutions and cultural foundations laid by Justinian endured, shaping the empire’s transformation into a more compact but distinctly Byzantine civilization.

Italy under the Lombards

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.

Mediterranean trade volume declines

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.

Sassanid Persians invasion

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, threatened the Empire’s very existence, his armies coming 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 thwarted the invasion only by launching a counter-attack into the heart of the Persian Empire that resulted, in the end, in a Byzantine victory. No sooner had the Empire repelled one threat than another appeared that would threaten the Empire with consequences far more severe.

Influence of the Prophet Muhammad

Under the influence of the Prophet Muhammad, the tribes of the Arabian deserts had been united under first the guidance of the Prophet and then his successors, the caliphs and the religion founded by Muhammad, Islam. Under the vigorous leadership of the first caliphs, Arab Muslim armies invaded both Sassanid Persia and the Byzantine Empire. At the Battle of Yarmouk in 636, although the Byzantines and Arabs were evenly matched, the Byzantine field army was badly beaten. In the aftermath, first Syria and Palestine and then Egypt fell from Christian Byzantine rule to the cultural and political influence of Islam.

Invasion of the Balkans

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.

Rural life in the Byzantine Empire

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.

Problem of the Byzantine Empire

Even more basic elements of a complex society, such as literacy and a cash economy, went into decline, although they did not cease. The Byzantine state issued less money and, indeed, most transactions ceased to be in cash at this time. The economy was demonetized. Even literacy rates shrank. Although churchmen and other elites would often still have an education, the days of the Roman state in which a large literate reading public would buy readily-available literature were gone. As in the west, literacy increasingly became the preserve of the religious.

Conclusion

The aftermath of Justinian’s reign stands as a pivotal era in Byzantine history—one of both decline and adaptation. While his ambitious projects and conquests had briefly restored imperial glory, they left the empire overextended, financially strained, and vulnerable to new enemies. The ensuing years witnessed territorial losses, demographic collapse, and administrative challenges that marked the end of the Byzantine Empire’s classical phase. Yet, out of this adversity emerged a more resilient, distinctly Eastern Christian state that would endure for centuries. Justinian’s legacy—his legal code, religious policies, and architectural achievements—continued to define Byzantine identity long after his empire’s borders had contracted, bridging the grandeur of Rome with the spirit of medieval Byzantium.
