(also Theodoricus, Theoderich). Born circa 454 in Pannonia; died Aug. 26, 526, in Ravenna.
Theodoric became king of the Ostrogoths in 493 and founded the Ostrogothic state in Italy. Having invaded Italy in 488, Theodoric seized power after he overthrew and assassinated Odoacer. He expressed the interests of the feudalized Ostrogothic aristocracy, which drew closer to the Roman aristocracy, and retained Roman institutions in his rule and legislation. The strengthening of central authority under Theodoric promoted the development of land cultivation, commerce, learning, and art.
