Antiochus II, surnamed Theos, was a ruler of Syria from 261 to 246 BC. His succession and marriages became involved in conflict between the Seleucid and Ptolemaic dynasties.
He is identified with the king of the north associated with the dynastic events described in Daniel 11:6.
Antiochus married Berenice of Egypt to secure peace, later recalled Laodice, and named her son as successor. Laodice then had Berenice, her child, and Antiochus killed. The Milesians called him Theos after he delivered them from Timarchus.
