Treaty of Ouchy

1912 · 20th century · Also known as First Treaty of Lausanne · Part of the Italo-Turkish War

The Treaty of Ouchy, signed at Ouchy near Lausanne on 18 October 1912, ended the Italo-Turkish War. The Ottoman Empire withdrew its forces and officials from Tripolitania and Cyrenaica, which Italy had already annexed as Libya. Italy was to hand back the Dodecanese islands once the Ottomans left Libya, but it kept them, and Turkey recognised Italian sovereignty over them in the Treaty of Lausanne of 1923.
