In 539 BC, Cyrus the Great made himself the King of Kings, and ruled all of West Asia. Along the coast of Anatolia (modern Turkey), Cyrus conquered first the Lydians and then the Greek cities that had been dependent on Lydia (LIH-dee-uh). The people who lived in these Greek cities in Turkey were called Ionians (eye-OH-nee-anns). Cyrus and the Persians made some changes in Ionia - they charged higher taxes and imposed tyrants who were loyal to the Persians. So the Ionians were not happy.
