Quick Summary

The Italo-Turkish War (1911-1912) was initiated by Italy to gain North African colonies by conquering the Turkish provinces of Tripolitana and Cyrenaica. This conflict exposed Turkey's weakness and fueled Italian nationalist sentiment. Italy's naval forces occupied Rhodes and some Dodecanese islands, while facing resistance in North Africa.

The Treaty of Lausanne (October 18, 1912), also known as the Treaty of Ouchy, concluded this war. Turkey ceded its rights over Tripoli and Cyrenaica to Italy. Although Italy agreed to evacuate the Dodecanese islands, its forces remained in occupation. This treaty is distinct from the 1923 Treaty of Lausanne, which finalized the boundaries of modern Turkey after World War I.12
