Tripolitania (today a part of Libya) is an area located next to the Mediterranean sea. It was controlled by Italy after the defeat of the Ottoman Empire during the Italo-Turkish War of 1911-1912. During the period of Italian control, stamps used in Tripolitania were Italian definitive stamps with overprints ("Tripoli di Barberia" until 1923, when the "Tripolitania" overprint was first used). The first stamps, overprinted "Tripolitania" on the Italian "Propogation of Faith" series, are pictured below. In 1926, Tripolitania began issuing its own stamps (as part of the colonial issues of Italy), which is pictured below, in addition to using the overprinted Italian definitives.
