The First Italo-Senussi War (1911–17) was a conflict between the Kingdom of Italy and the Senussi for control of Libya, primarily in Cyrenaica.^[1] It had two main active phases:

• The Italo-Turkish War (1911–12), when Italy invaded Libya, then the Ottoman vilayet of Trâblus Gârb
• The Senussi Campaign (1915–17), part of the First World War, in which Italian and British forces fought the Ottoman- and German-supported Senussi

After a period of relative peace, the Second Italo-Senussi War broke out in 1923 and lasted until 1932.
