Mysia (UK , US or ; Greek: Μυσία; Latin: Mysia; Turkish: Misya) was a region in the northwest of ancient Asia Minor[1] (Anatolia, Asian part of modern Turkey). It was located on the south coast of the Sea of Marmara. It was bounded by Bithynia on the east, Phrygia on the southeast, Lydia on the south, Aeolis on the southwest, Troad on the west, and the Propontis on the north. In ancient times it was inhabited by the Mysians, Phrygians, Aeolian Greeks and other groups.
The precise limits of Mysia are difficult to assign. The Phrygian frontier was fluctuating, while in the northwest the Troad was only sometimes included in Mysia.[1] The northern portion was known as "Lesser Phrygia" or (Ancient Greek: μικρὰ Φρυγία, romanized: mikra Phrygia; Latin: Phrygia Minor), while the southern was called "Greater Phrygia" or "Pergamene Phrygia". Mysia was in later times also known as Hellespontine Phrygia (Ancient Greek: Ἑλλησποντιακὴ Φρυγία, romanized: Hellespontiake Phrygia; Latin: Phrygia Hellespontica) or "Acquired Phrygia" (Ancient Greek: ἐπίκτητος Φρυγία, romanized: epiktetos Phrygia; Latin: Phrygia Epictetus), so named when the region was annexed to the Attalid kingdom.[2]
Under Augustus, Mysia occupied the whole of the northwest corner of Asia Minor, between the Hellespont and the Propontis to the north, Bithynia and Phrygia to the east, Lydia to the south, and the Aegean Sea to the west.[3]
