are first attested. All of these initiatives were probably aimed at emphasising Ionian distinctiveness from other Greeks in Asia. But the Ionian League was primarily a religious organisation rather than a political one. Although they did sometimes act together, civic interests and priorities always trumped broader Ionian ones. They never formed a real confederacy. The advice of Thales of Miletus to combine in a political union was rejected. In inscriptions and literary sources from this period, Ionians generally identify themselves by their city of origin, not as "Ionians." Ionians overseas The cities became prosperous. Miletus especially was, in an early period, one of the most important commercial cities of Greece, and in its turn became the parent of numerous other colonies, which extended all around the shores of the Euxine Sea and the Propontis from Abydus and Cyzicus to Trapezus and Panticapaeum. Phocaea was one of the first Greek cities whose mariners explored the shores of the western Mediterranean. Ephesus, though it did not send out any colonies of importance, from an early period became a flourishing city. In the eighth century Ionian Greeks are recorded in Near Eastern sources as coastal raiders: an inscription of Sargon II (ca 709–07, recording a naval expedition of 715) boasts "in the midst of the sea" he had "caught the Ionians like fish and brought peace to the land of Que Cilicia and the city of Tyre". For a full generation earlier, Assyrian inscriptions had recorded troubles with the Ionians, who escaped on their boats. Lydian rule About 700 BC Gyges, first Mermnad king of Lydia, invaded the territories of Smyrna and Miletus, and is said to have taken Colophon. His son Ardys conquered Priene. In the middle of the 7th century, the Cimmerii ravaged a great part of Asia Minor, including Lydia, and sacked Magnesia on the Maeander, but were defeated when they attacked Ephesus. It was not until the reign of Croesus (560–545 BC) that the cities of Ionia fell completely under Lydian rule. First Achaemenid rule The defeat of Croesus by Cyrus the Great was followed by the conquest of all the Ionian cities in 547 BC. These became subject to the Persian monarchy with the other Greek cities of Asia, forming part of the satrapy of Lydia. In this position they enjoyed a considerable amount of autonomy, but were subject to local despots (called "tyrants"), who were loyal to
