Theodemir was succeeded by his son Theodoric in 471, who was forced to compete with Theodoric Strabo, leader of the Thracian Goths, for the leadership of his people. Fearing the threat posed by Theodoric to Constantinople, the Eastern Roman emperor Zeno ordered Theodoric to invade Italy in 488. By 493, Theodoric had conquered all of Italy from the Scirian Odoacer, whom he killed with his own hands; he subsequently formed the Ostrogothic Kingdom. Theodoric settled his entire people in Italy, estimated at 100,000-200,000, mostly in the northern part of the country, and ruled the country very efficiently. The Goths in Italy constituted a small minority of the population in the country. Intermarriage between Goths and Romans were forbidden, and Romans were also forbidden from carrying arms. Nevertheless, the Roman majority was treated fairly.
