Odaenathus vs Odoacer

Odaenathus, king of Palmyra, organized a successful defense of the Roman eastern provinces after Emperor Valerian was captured by the Sassanid king Shapur I. He defeated the Sassanid forces, drove them back across the Euphrates, and restored Roman authority in Syria and Mesopotamia.

Odaenathus launched a major campaign against the Sassanid Empire, recapturing the cities of Nisibis and Carrhae. He besieged the Sassanid capital of Ctesiphon but was unable to take it. His victories secured the Roman eastern frontier and earned him the title of Corrector Totius Orientis.

Odaenathus was assassinated along with his eldest son Herodianus at Emesa, allegedly on the orders of his wife Zenobia or his nephew Maeonius. His death created a power vacuum that allowed Zenobia to take control of Palmyra and expand the Palmyrene Empire.

Odoacer, leading a revolt of Germanic foederati, deposed the Western Roman Emperor Romulus Augustulus. He sent the imperial regalia to the Eastern Roman Emperor Zeno, effectively ending the Western Roman Empire.

After deposing Romulus Augustulus, Odoacer was proclaimed King of Italy by his troops. He ruled Italy autonomously while nominally recognizing the authority of the Eastern Roman Emperor, establishing a new political order.

The Eastern Roman Emperor Zeno sent the Ostrogothic king Theodoric the Great to invade Italy and overthrow Odoacer. Odoacer's forces were defeated at the battles of Isonzo and Verona, leading to a prolonged siege of Ravenna.

Odoacer surrendered Ravenna to Theodoric after a three-year siege. Under a truce, Theodoric invited Odoacer to a banquet and killed him with his own hands, ending Odoacer's rule and establishing the Ostrogothic Kingdom of Italy.
