Odaenathus of Palmyra

After Roman Emperor Valerian was captured by the Sassanid king Shapur I, Odaenathus of Palmyra led a successful campaign against the Persians. He defeated Shapur's forces, drove them back across the Euphrates, and secured the Roman eastern frontier.

Roman Emperor Gallienus recognized Odaenathus as King of Palmyra and appointed him Corrector Totius Orientis (Governor of the East). This gave Odaenathus authority over the Roman eastern provinces, effectively making him the ruler of the Roman East.

Odaenathus led a military campaign against the Goths who were raiding Asia Minor. He successfully defeated them, further securing the Roman eastern provinces and demonstrating his military prowess.

Odaenathus was assassinated along with his eldest son Herodianus at Emesa. The assassination was likely orchestrated by his nephew or by his wife Zenobia. This event led to Zenobia taking power in Palmyra.
