CASTELLORIZO, the ancient Megiste, an island of the Dodecanese. It was included by the Turks in the privileged group known as "the Dodecanese" (q.v.), but did not form part of the Italian "Dodecanese" occupied during the Libyan War of 1912. The outbreak of hostilities against Turkey during the World War gave the Italians an opportunity of adding Castel lorizo to their Dodecanesian possessions, of ter the French had occupied it on Dec. 27, 1915. Articles 122 of the Treaty of Sevres in 1920 and 15 of the second Treaty of Lausanne in 1923 provided that "Turkey renounces in favour of Italy all rights and title . . . over the island of Castellorizo." Its population is entirely Greek.
