After the Sassanid Empire's defeat and expulsion from Roman Syria and Cappadocia in 260 at the hands of Odaenathus and Balista, the Palmyrene king seized the initiative and invaded Mesopotamia, pushing deep into Sassanid territory toward the imperial capital of Ctesiphon.
In 263, Odaenathus led his Palmyrene army to the walls of Ctesiphon, devastating the surrounding region. Despite reaching the capital, logistical difficulties of operating in hostile territory prevented the Palmyrenes from taking the city itself, and the siege ultimately failed to breach Ctesiphon's defenses.
The Palmyrenes withdrew from Ctesiphon carrying large numbers of prisoners and considerable booty. The captives were dispatched to Rome, where Emperor Gallienus was able to celebrate a formal triumph, boosting Roman prestige despite Palmyra having conducted the campaign largely independently.
