Area of E Libya, colonized by the Greeks in the 7th century BC; later held by the Egyptians, Romans, Arabs, Turks, and Italians. Present cities in the region are Benghazi, Derna, and Tobruk. The Greek colonies passed under the rule of the Ptolemies 322 BC, and in 174 BC Cyrenaica became a Roman province. It was conquered by the Arabs in the 7th century, by Turkey in the 16th, and by Italy 1912, when it was developed as a colony. It was captured by the British 1942, and under British control until it became a province of the new kingdom of Libya from 1951. In 1963 it was split into a number of smaller divisions under the constitutional reorganization. There are archaeological ruins at Cyrene and Apollonia.
