Isauria, in ancient geography, is a rugged isolated district in the interior of South Asia Minor, of very different extent at different periods, but generally covering what is now the district of Bozkir and its surroundings in the Konya province of Turkey, or the core of the Taurus Mountains. In its coastal extension it bordered on Cilicia. It derives its name from the contentious Isaurian tribe (probably Luwian) and twin settlements Isaura Palaea (Isayra Palaia, Latin: Isaura Vetus, "Old Isaura") and Isaura Nea (Isayra Nea, Latin: Isaura Nova, "New Isaura"). Isaurian marauders were fiercely independent mountain people who created havoc in neighboring districts under Macedonian and Roman occupations. The permanent nucleus of Isauria was north of the Taurus range which lies directly to south of Iconium and Lystra. Lycaonia had all the Iconian plain; but Isauria began as soon as the foothills were reached.
