Anatolia is a peninsula of Western Asia which forms the greater part of the Asian portion of Turkey, as opposed to the European portion (Thrace, or traditionally Rumelia). Bounded by the Black Sea to the north, the Mediterranean Sea to the south, the Aegean Sea (itself an arm of the Mediterranean) to the west, and the bulk of the Asian mainland to the east, the Anatolian peninsula is often called by the Latin name of Asia Minor, which comes from the Greek Mikra Asia. The name comes from the Greek phrase meaning "rising of the sun," or "east."
