Western Thrace

Western Thrace (Greek: Δυτική Θράκη, IPA: [ðitiˈci ˈθɾaci]), also known as Greek Thrace or Aegean Thrace, is a geographical and historical region of Greece, between the Nestos and Evros rivers in the northeast of the country. It is the western part of Thrace; East Thrace, which lies east of the river Evros, forms the European part of Turkey, and the area to the north, in Bulgaria, is known as Northern Thrace. Greek Thrace is divided into three regional units (former prefectures): Xanthi, Rhodope and Evros, which together with the Macedonian regional units of Drama, Kavala and Thasos form the region of Eastern Macedonia and Thrace. The largest city of the region is Alexandroupolis.

Inhabited since Paleolithic times, it has been under the political, cultural and linguistic influence of the Greek world since the classical era. Under the Byzantine Empire, Western Thrace was part of the theme of Thrace and then of Macedonia and benefited from its position close to the imperial heartland and became a center of medieval Greek commerce and culture; later, under the Ottoman Empire, a number of Muslims settled there, marking the birth of the Muslim minority of Greece.

Topographically, Thrace alternates between mountain-enclosed basins of varying size and deeply cut river valleys. The Fourth Army Corps of the Hellenic Army has its headquarters in Xanthi; in recent years, the region has attracted international media attention after becoming a key entering point for illegal immigrants trying to enter European Union territory; Greek security forces, working together with Frontex, are also extensively deployed in the Greco-Turkish land border.
