Historical Trajectory
Phase I: Rise
Theodoric the Great led the Ostrogoths into Italy under nominal authorization from the Byzantine emperor Zeno. After defeating and killing Odoacer in 493 — the Germanic soldier who had deposed the last Western Roman emperor in 476 — Theodoric established his kingdom with Ravenna as capital. He expanded control into southern France and the western Balkans, styling himself king of both Goths and Romans.
Phase II: Zenith
At its height under Theodoric, the kingdom stretched from southern France to western Serbia, encompassing the Italian peninsula and Dalmatia. Theodoric preserved the late Roman administrative apparatus, retaining Roman law, senatorial institutions, and civil bureaucracy. Roman intellectuals such as Boethius and Cassiodorus served at court, maintaining Latin learning and cultural continuity across the transition from imperial to Gothic rule.
Phase III: Decline
Following Theodoric's death in 526, succession disputes weakened central authority. Justinian I launched the Gothic War in 535, and King Witiges was captured when Ravenna fell in 540. The resilient Ostrogothic king Totila briefly reversed Byzantine gains but was killed at the Battle of Busta Gallorum in 552. His successor Teia fell the following year, ending the kingdom and incorporating Italy into the Byzantine Empire.
