Answer
The Second Syrian War between Egypt under Ptolemy II and the Seleucid Empire under Antiochus II Theos was a territorial dispute over Coele-Syria and Phoenicia. The decisive victory of Antiochus II at the Battle of Raphia in 217 BC ultimately resulted in the Seleucid conquest of these territories. This victory marked the decline of Ptolemaic influence in Southern Syria and the rise of Seleucid power.
