Asia Mi'nor, the most westerly portion of Asia, the peninsula lying west of the upper Euphrates and forming part of Asiatic Turkey. In ancient times its chief divisions were Pontus, Paphlagonia, Bithynia, Mysia, Lydia, Caria, Lycia, Pisidia, Pamphylia, Cilicia, Isauria, Cappadocia, Galatia, Phrygia and Lycaonia. The Greeks had numerous colonies in Asia Minor, and it was the assistance which Greece rendered to some of the cities of Asia Minor in their attempt to throw off Persian dominion which led to the invasion of Greece. The modern name of Asia Minor is Anatolia.
