Byzantine Empire - The age of Justinian I

The reign of Justinian I, which began in 527, saw a period of extensive imperial conquests of former Roman territories (indicated in green on the map below). The 6th century also saw the beginning of a long series of conflicts with the Byzantine Empire's traditional early enemies, such as the Sassanid Persians, Slavs and Bulgars. Theological crises, such as the question of Monophysitism, also dominated the empire.

Justinian I had perhaps already exerted effective control during the reign of his predecessor, Justin I (518–527). Justin I was a former officer in the imperial army who had been chief of the guards to Anastasius I, and had been proclaimed emperor (when almost 70) after Anastasius' death. Justinian was the son of a peasant from Illyricum, but was also a nephew of Justin. Justinian was later adopted as Justin's son. Justinian would become one of the most refined people of his century, inspired by the dream to re-establish Roman rule over all the Mediterranean world. He reformed the administration and the law, and with the help of brilliant generals such as Belisarius and Narses, he temporarily regained some of the lost Roman provinces in the west, conquering much of Italy, North Africa, and a small area in southern Spain.

In 532, Justinian secured for the Eastern Roman Empire peace on the eastern frontier by signing an "eternal peace" treaty with the Sassanid Persian king Khosrau I. However, this required in exchange a payment of a huge annual tribute of gold.

Justinian's conquests in the west began in 533 when Belisarius was sent to reclaim the former province of North Africa with a small army of 18,000 men who were mainly mercenaries. Whereas an earlier expedition in 468 had been a failure, this new venture was successful. The kingdom of the Vandals at Carthage lacked the strength of former times under King Gaiseric and the Vandals surrendered after a couple of battles against Belisarius' forces. General Belisarius returned to a Roman triumph in Constantinople with the last Vandal king, Gelimer, as his prisoner. However, the reconquest of North Africa would take a few more years to stabilize. It was not until 548 that the main local independent tribes were entirely subdued.

In 535, Justinian I launched his most ambitious campaign, the reconquest of Italy. At the time, Italy was still ruled by the Ostrogoths. He dispatched an army to march overland from Dalmatia while the main contingent, transported on ships and again under the command of General Belisarius, disembarked in Sicily and conquered the island without much difficulty. The marches on the Italian mainland were initially victorious and the major cities, including Naples, Rome and the capital Ravenna, fell one after the other. The Goths were seemingly defeated and Belisarius was recalled to Constantinople in 541 by Justinian. Belisarius brought with him to Constantinople the Ostrogoth king Witiges as a prisoner in chains. However, the Ostrogoths and their supporters were soon reunited under the energetic command of Totila. The ensuing Gothic Wars were an exhausting series of sieges, battles and retreats which consumed almost all the Byzantine and Italian fiscal resources, impoverishing much of the countryside. Belisarius was recalled by Justinian, who had lost trust in his preferred commander. At a certain point, the Byzantines seemed to be on the verge of losing all the positions they had gained. After having neglected to provide sufficient financial and logistical support to the desperate troops under Belisarius' former command, in the summer of 552 Justinian gathered a massive army of 35,000 men (mostly Asian and Germanic mercenaries) to contribute to the war effort. The astute and diplomatic eunuch Narses was chosen for the command. Totila was crushed and killed at the Busta Gallorum. Totila's successor, Teias, was likewise defeated at the Battle of Mons Lactarius (central Italy, October 552). Despite continuing resistance from a few Goth garrisons, and two subsequent invasions by the Franks and Alamanni, the war for the reconquest of the Italian peninsula came to an end.

Justinian's program of conquest was further extended in 554 when a Byzantine army managed to seize a small part of Spain from the Visigoths. All the main Mediterranean islands were also now under Byzantine control. Aside from these conquests, Justinian updated the ancient Roman legal code in the new Corpus Juris Civilis. Even though the laws were still written in Latin, the language itself was becoming archaic and poorly understood even by those who wrote the new code. Under Justinian's reign, the Church of Hagia Sofia ("Holy Wisdom") was constructed in the 530s. This church would become the center of Byzantine religious life and the center of the Eastern Orthodox form of Christianity. The 6th century was also a time of flourishing culture and even though Justinian closed the university at Athens, the Eastern Roman Empire produced notable people such as the epic poet Nonnus, the lyric poet Paul the Silentiary, the historian Procopius, the natural philosopher John Philoponos and others.

The conquests in the west meant that the other parts of the Eastern Roman Empire were left almost unguarded even though Justinian was a great builder of fortifications in Byzantine territories throughout his reign. Khosrau I of Persia had, as early as 540, broken the pact previously signed with Justinian and plundered Antiochia. The only way Justinian could forestall him was to increase the sum he paid to Khosrau I every year. The Balkans were subjected to repeated incursions where Slavs had first crossed the imperial frontiers during the reign of Justin I. The Slavs took advantage of the sparsely-deployed Byzantine troops and pressed on as far as the Gulf of Corinth. The Kutrigur Bulgars had also attacked in 540. The Slavs invaded Thrace in 545 and in 548 assaulted Dyrrachium, an important port on the Adriatic Sea. In 550, the Sclaveni pushed on as far to reach within 65 kilometers of Constantinople itself. In 559, the Eastern Roman Empire found itself unable to repel a great invasion of Kutrigurs and Sclaveni. Divided in three columns, the invaders reached Thermopylae, the Gallipoli peninsula and the suburbs of Constantinople. The Slavs feared the intact power of the Danube Roman fleet and of the Utigurs (paid by the Romans themselves) more than the resistance of the ill-prepared Byzantine imperial army. This time the Eastern Roman Empire was safe, but in the following years the Roman suzerainty in the Balkans was to be almost totally overwhelmed.

Soon after the death of Justinian in 565, the Germanic Lombards, a former imperial foederati tribe, invaded and conquered much of Italy. The Visigoths conquered Cordoba, the main Byzantine city in Spain, first in 572 and then definitively in 584. The last Byzantine strongholds in Spain were swept away twenty years later. The Turks emerged in the Crimea, and in 577, a horde of some 100,000 Slavs had invaded Thrace and Illyricum. Sirmium, the most important Roman city on the Danube, was lost in 582, but the Eastern Roman Empire managed to mantain control of the river for several more years even though it increasingly lost control of the inner provinces.

Justinian's successor, Justin II, refused to pay the tribute to the Sassanid Empire. This resulted in a long and harsh war which lasted until the reign of his successors Tiberius II and Maurice, and focused on the control over Armenia. Fortunately for the Byzantines, a civil war broke out in the Persian Empire. Maurice was able to take advantage of his friendship with the new king Khosrau II (whose disputed accession to the Persian throne had been assisted by Maurice) in order to sign a favorable peace treaty in 591. This treaty gave the Eastern Roman Empire control over much of western Armenia. Maurice reorganized the remaining Byzantine possessions in the west into two Exarchates, the Ravenna and the Carthage. Maurice increased the Exarchates' self-defense capabilities and delegated them to civil authorities.

The Avars and later the Bulgars overwhelmed much of the Balkans, and in the early 7th century the Sassanids invaded and conquered Egypt, Palestine, Syria and Armenia. The Persians were eventually defeated and the territories were recovered by Emperor Heraclius in 627. However, the unexpected appearance of the newly-converted and united Muslim Arabs took the territories by surprise from an empire exhausted from fighting against Persia, and the southern provinces were overrun. The Eastern Roman Empire's most catastrophic defeat of this period was the Battle of Yarmuk, fought in Syria. Heraclius and the military governors of Syria were slow to respond to the new threat, and Byzantine Mesopotamia, Syria, Egypt, and the Exarchate of Africa were permanently incorporated into the Muslim Empire in the 7th century, a process which was completed with the fall of Carthage to the Caliphate in 698.

The Lombards continued to expand in northern Italy, taking Liguria in 640 and conquering most of the Exarchate of Ravenna in 751, leaving the Byzantines with control of only small areas around the toe and heel of Italy, plus some semi-independent coastal cities like Venice, Naples, Amalfi and Gaeta.
