Seleucus XII Nicephorus

Seleucus XII Theopator Epiphanes Nicephorus Asiaticus Euergetes (Greek: Σέλευκος ΙʹΒʹ Θεόπάτωρ Ἐπιφανής Νικηφόρος Ἀσιατικός Ευεργέτης) was the n-th Basileus of the Seleucid Empire. He reigned from 191 to 230, succeeding his father Athenadorus I Balas after his death in the First Bosucheonic War. A successful soldier-emperor, Seleucus oversaw the greatest extent achieved by the Empire, with his eponymous conflict playing a key role. He also implemented beneficial social welfare programs, which made him a popular ruler and earned him the epithet Euergetes.
