Theodoric the Great: The Barbarian Who Grew Up in Constantinople and Built the Most Civilized Kingdom in the West

At age eight, Theodoric was sent to Constantinople as a hostage — a guarantee of his father's good behavior, a small boy handed over to the Roman Emperor to live among foreigners. He stayed for ten years and came back one of the most educated men in the Ostrogoth nation. Then he led 250,000 people over the Alps into Italy, defeated the existing king in a series of battles, invited the man to a peace banquet, and killed him there. He ruled for thirty-three years and built something the western world badly needed: a kingdom that actually worked.

Theodoric the Great: The Barbarian Who Grew Up in Constantinople and Built the Most Civilized Kingdom in the West

At age eight, Theodoric was sent to Constantinople as a hostage — a guarantee of his father's good behavior, a small boy handed over to the Roman Emperor to live among foreigners. He stayed for ten years and came back one of the most educated men in the Ostrogoth nation. Then he led 250,000 people over the Alps into Italy, defeated the existing king in a series of battles, invited the man to a peace banquet, and killed him there. He ruled for thirty-three years and built something the western world badly needed: a kingdom that actually worked.

The Roman Empire had a system for managing dangerous neighboring kings. When you made a treaty with a powerful chief whose loyalty you did not entirely trust, you asked for a hostage — usually a child of the king's family, who would live at the imperial court as an honored guest and an implicit threat. If the king violated the treaty, the hostage's life was forfeit. Theodemir, king of the Ostrogoths, sent his eight-year-old son to Constantinople under exactly this arrangement. The boy stayed for ten years. The Emperor Leo treated him well. He was educated with care, trained in Roman military arts, exposed to a level of civilization that most Ostrogoths never encountered. When he came home at eighteen to become king of his people, Theodoric was something his father had not been and his warriors could not quite understand: a barbarian who genuinely understood Rome from the inside.

Theodoric the Great, king of the Ostrogoths and ruler of Italy from 493 to 526 AD, who transformed his barbarian kingdom into the most stable realm in post-Roman western Europe.

The Migration of an Entire Nation

The Emperor Zeno had a problem with Theodoric. The Ostrogoth king kept making war — against other Gothic kings, against Roman territories, against anyone who was nearby. After years of fighting and occasional peace, Zeno found a solution: he suggested that Theodoric take his people to Italy and displace Odoacer, the man who was currently running the place. Odoacer was himself a barbarian chief who had deposed the last western Roman emperor, Romulus Augustulus, in 476 — the year conventionally used to mark the fall of the Western Roman Empire. He had taken the title of patrician rather than emperor, governed reasonably well, and been accepted by most of the Roman population of Italy. Theodoric was delighted with the proposal. He began organizing immediately. What he assembled was not an army. It was a migration. He set out with 250,000 people — men, women, and children — plus horses and wagons and sixty thousand soldiers. They traveled from the shores of the Black Sea overland across mountains and through hostile tribal territories. They defeated the savage tribes that tried to stop them and made prisoners of the women and men who fell into their hands to carry baggage and do work. The journey took months. When the Ostrogoths finally crested the Alps and looked south into the Italian peninsula, the ancient accounts say they shouted and danced. Theodoric reportedly cried out: There is the country which shall be our home. Let us march on. It certainly shall be ours.

Four Battles, One Kingdom

Odoacer was not going to hand Italy over without a fight. He had assembled an army and marched north to meet the invaders. The two forces met near Aquileia. Odoacer was defeated. He tried to buy Theodoric off — thousands of pounds of gold and silver to take his people back to their own country. Theodoric said he had as good a right to rule Italy as Odoacer and was staying. A second battle near Verona produced another Ostrogoth victory, though Theodoric came close to losing his life there. His army began to waver at one critical moment, and the thing that steadied it was his mother, who was in the camp and saw men running from the section of the battle where her son was fighting. She ran forward herself and stopped the fleeing soldiers, shamed them into turning back. They returned to the field and won. Odoacer retreated to Ravenna — a city so well-protected by walls and marshes that it was essentially impossible to take by assault. Theodoric surrounded it and cut off its supplies. The siege lasted years. Eventually starvation forced Odoacer to negotiate. The two kings agreed to rule jointly. A banquet was arranged to seal the peace. At the banquet, Theodoric killed Odoacer. He then divided a third of Italy's land among his Ostrogoth followers and declared himself sole ruler. Romans, Visigoths, and Ostrogoths alike were to be governed as one people.

Thirty-Three Years of Something Rare

What followed Theodoric's consolidation of power was, by the standards of the post-Roman west, exceptional. He governed Italy for thirty-three years. He made good laws. He maintained Roman administrative structures rather than dismantling them. He treated the Roman population as citizens rather than as a conquered people to be exploited. He kept his Ostrogoth warriors from brutalizing the locals. He built things: public buildings, aqueducts, drainage works for the Po Valley marshes. The scholars and philosophers of the Roman tradition flourished at his court. Boethius, who wrote The Consolation of Philosophy (still read today), served him as a senior official. Cassiodorus wrote histories and preserved Roman learning through the chaos of the age. He was not a perfect ruler. The end of his reign was troubled — he became suspicious of Roman senators, including Boethius, and had some of them executed. But in the sweep of the thing, Theodoric the Great deserved the name later generations gave him. The boy who had been sent to Constantinople as a hostage, who had spent a decade learning how civilization worked, had come back and built one. It lasted thirty-three years — longer than most things in that century — before slowly unraveling after his death.
