Antiochus II inherited not only an empire from his father Antiochus I, but also the Second Syrian War between the Seleucids and the Ptolemies. He was successful insofar as he reconquered some important areas in Asia Minor including Ionia and Cilicia, and eventually made peace with Ptolemy II. However, two of his eastern provinces, Bactria and Parthia, revolted and became independent kingdoms, the first step in the long decline of the Seleucid Empire
