Anatolia, is a large peninsula in Western Asia and the westernmost protrusion of the Asian continent. It makes up the majority of modern-day Turkey. The region is bounded by the Turkish Straits to the northwest, the Black Sea to the north, the Armenian Highlands (part of the Eastern Anatolia Region) to the east, the Southeastern Anatolia Region (which borders Iraq and Syria) to the southeast, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean seas through the Bosporus and Dardanelles straits and separates Anatolia from Thrace on the Balkan peninsula of Southeast Europe.
