The dominance of Arabic and Turkish is the result of the medieval Arab and Turkic invasions beginning with the Islamic conquests of the 7th century AD, which displaced the formerly dominant Aramaic and Hebrew in the Levant, and Greek in Anatolia, although Hebrew is once again the dominant language in Israel, and Aramaic  and Greek both remain present in their respective territories as minority languages. Other significant native minorities include Assyrians, Druze, Jews, Mandeans, Maronites, Shabaks, Syriac Arameans, Lurs and Yezidis.
