Theodoric (or Theoderic) the Great (about 454 – 30 August 526), also called the Amal, was king of the Ostrogoths (475–526), and ruler of the Ostrogothic Kingdom of Italy between 493 and 526, regent of the Visigoths (511–526), and a patrician of the Eastern Roman Empire. As ruler of the combined Gothic realms, Theodoric controlled an empire stretching from the Atlantic Ocean to the Adriatic Sea. Though Theodoric himself only used the title 'king' (rex), some scholars characterize him as a Western Roman emperor in all but name, since he ruled a large part of the former Western Roman Empire. He also received and used the former Western imperial regalia from Constantinople in 497, and exercised imperial powers recognized in the East, such as naming consuls. The Italian aristocracy referred to him using the imperial title princeps .
As a young child of an Ostrogothic nobleman, Theodoric was taken as a hostage to Constantinople, where he spent his formative years and received an East Roman education (paideia). Theodoric returned to Pannonia around 470, and throughout the 470s he campaigned against the Sarmatians and competed for influence among the Goths of the Roman Balkans, gaining recognition as king in 471. The emperor Zeno made him commander of the Eastern Roman forces in 483 and consul in 484. Nevertheless, Theodoric remained in constant hostilities with the emperor and frequently raided East Roman territory.
