Antiochus I Soter

Who was Antiochus I Soter?

Antiochus I Soter, was a king of the Hellenistic Seleucid Empire. He reigned in 281–261 BC.

Antiochus I was half Persian, his mother Apama being one of the eastern princesses whom Alexander the Great had given as wives to his generals in 324 BC. In 294 BC, prior to the death of his father Seleucus I, Antiochus married his stepmother, Stratonice, daughter of Demetrius Poliorcetes. His elderly father reportedly instigated the marriage after discovering that his son was in danger of dying of lovesickness. Stratonice bore five children to Antiochus: Seleucus, Laodice, Apama II, Stratonice of Macedon and Antiochus II Theos, who succeeded his father as king.

On the assassination of his father in 281 BC, the task of holding together the empire was a formidable one. A revolt in Syria broke out almost immediately. Antiochus was soon compelled to make peace with his father's murderer, Ptolemy Keraunos, apparently abandoning Macedonia and Thrace. In Anatolia he was unable to reduce Bithynia or the Persian dynasties that ruled in Cappadocia.
