What happened
Between 488 and 493 CE, with Byzantine backing, the Ostrogothic king Theodoric invaded Italy, defeated Odoacer, and then had Odoacer killed after pretending to offer him peace terms. Ruling from Ravenna, Theodoric governed Italy through existing Roman civil administration rather than replacing it, repaired war damage, replanted forests, restored cities, and enlarged irrigation systems. Because his Ostrogoths practiced Arian Christianity while most Italians were Nicene Christians, Theodoric mandated religious tolerance to keep the peace between the two communities, and he kept Roman intellectuals such as the philosopher Boethius at his court. After Theodoric died in 526 CE, his daughter Amalasuntha ruled as regent and then queen, but the kingdom's stability did not survive her, and growing conflict with the Byzantine Empire triggered the Gothic War that destroyed Ostrogothic rule in Italy by 553 CE.
Why it matters
Theodoric's reign showed that a Germanic kingdom could govern Italy by keeping Roman law, administration, and equal taxation intact rather than dismantling them, a model of continuity between the ancient and medieval periods that later Italian kingdoms did not replicate as successfully. The two decades of Byzantine warfare that followed his death devastated the peninsula and opened the door to the next invasion, by the Lombards, within a generation.
How we know
Theodoric's reign is documented by contemporary Roman administrators including Cassiodorus, whose official correspondence as Theodoric's minister survives, and by later Byzantine historians who recorded the Gothic War that ended Ostrogothic rule.
