Arzawa is a region or kingdom in what was later to be known as Lydia in Western Anatolia. It was the western neighbour and sometimes vassal of the Hittites, and probably bordered on the Assuwa league to the north. The language spoken in Arzawa during the Bronze Age and early Iron Age was Luwian, a member of the Anatolian branch of the Indo-European family. Its capital was Apasa (or Abasa), according to Hittite sources, which may correspond to the later Lydian capital Ephesus.
