The Italo-Turkish War, also known as the Turco-Italian War, was fought between the Kingdom of Italy and the Ottoman Empire from 29 September 1911 to 18 October 1912. As a result of this conflict, Italy captured coastal areas of the Ottoman Tripolitania Vilayet, of which the main sub-provinces were Fezzan, Cyrenaica, and Tripoli itself. These territories became the colonies of Italian Tripolitania and Cyrenaica, which would later merge into Italian Libya.
