Historical Trajectory
Phase I: Rise
The kingdom emerged in 476 AD when the Germanic chieftain Odoacer defeated and deposed Romulus Augustulus, the last Western Roman emperor, at the Battle of Ravenna. Odoacer then proclaimed himself Rex, or king, over Italy. This act is traditionally regarded as the definitive end of the Western Roman Empire, establishing the first post-Roman barbarian kingdom on Italian soil.
Phase II: Zenith
Odoacer ruled Italy for roughly seventeen years, maintaining much of the Roman administrative infrastructure and cooperating with the Roman Senate. He governed the Italian peninsula, nominally acknowledging the suzerainty of the Eastern Roman Emperor in Constantinople while exercising independent authority over taxation, law, and military affairs within the former western heartland.
Phase III: Decline
Theodoric the Great, king of the Ostrogoths, invaded Italy at the behest of the Eastern Emperor Zeno in 489 AD. After several military defeats, Odoacer was besieged in Ravenna and eventually agreed to a negotiated co-rule in 493. Theodoric then assassinated Odoacer at a banquet, dissolving the kingdom and replacing it with the Ostrogothic Kingdom of Italy.
