Works & Achievements
Major codification of Roman law in four parts, which laid the foundations of most European legal systems. This legislative monument is still studied in law schools today.
Cathedral built in five years in Constantinople after the destruction of the former basilica. It was the largest Christian church in the world for nearly a millennium.
Led by General Belisarius, this lightning campaign ended the Vandal kingdom in less than a year and restored Roman dominion over the western Mediterranean.
A long and costly military campaign that allowed Justinian to retake Italy from the Ostrogoths. It considerably exhausted the empire's human and financial resources, however.
Justinian took advantage of internal strife within the Visigothic kingdom to seize the Spanish Mediterranean coast, bringing the empire to its greatest extent since the fall of Rome.
A vast fortification program along the empire's borders, particularly against the Sasanian Persians. These military construction projects testify to Justinian's systematic defense policy.
Anecdotes
In 532, a terrible riot broke out in Constantinople: the Nika revolt. The city burned and Justinian, in a panic, considered fleeing by ship. It was his wife Theodora who dissuaded him with a now-famous line: 'Purple is the finest of shrouds.' Justinian stayed, crushed the revolt, and consolidated his power.
Justinian married Theodora, a woman of humble origins who had been an actress and mime — professions considered disreputable at the time. To make the marriage possible, he had the law changed that prevented senators from marrying women of low social standing. Theodora became one of the most influential empresses in Byzantine history.
In 541, an outbreak of bubonic plague swept through the empire from Egypt. Justinian himself contracted the disease and barely survived. This 'Plague of Justinian' killed millions and durably weakened the empire, casting doubt over all of its military conquests.
After the old basilica was destroyed during the Nika revolt, Justinian ordered the construction of a new Hagia Sophia in record time: just five years. At its inauguration in 537, he reportedly declared upon entering the building: 'Solomon, I have surpassed you!' — a reference to the Temple of Jerusalem.
Justinian barely slept. His contemporaries nicknamed him 'the emperor who never sleeps'. He worked through the night, studying legal and theological files until dawn, and his historian Procopius reports that he was sometimes seen wandering alone through the palace corridors by lamplight, like a crowned ghost.

Justinian was by nature cunning and cruel, quick to conceal his thoughts, never angry for any serious reason, but always affable and smiling during the most wicked acts.
We have decided to set forth in a brief compilation all the imperial constitutions scattered across the ancient codes... so that no one need search for the law through countless volumes.
By divine authority, we have governed our empire, and we have striven to bring it to perfection in times of war as in times of peace.
Belisarius, general of Emperor Justinian, crossed with his army the strait toward Africa, and in less than a year he had put an end to the Vandal kingdom that had lasted for a century.
The two greatest gifts that God, in His heavenly goodness, has granted to men are the priesthood and the empire: the one serves divine things, the other governs and tends to human affairs.
