The Kingdom of Italy signed the Treaty of Lausanne/Ouchy with the Ottoman Empire at Ouchy, in the south of Lausanne, Switzerland. The treaty ended the Italo-Turkish War, with the Ottomans agreeing to withdraw from Trablus and Benghazi vilayets (Libya) in return for the Italian withdrawal from Rhodes and the other Aegean islands it had occupied during the war.
