In August 1915 Italy declared war on the Ottoman Empire. While it sent no troops to the main Allied fronts against the Ottomans, it fought this enemy both at sea and on land, in a form of proxy conflict. Turkey, Germany, and Austria sent funds and army officers to support anti-Italian insurrections both in Cyrenaica and Tripolitania, with varying results; a combination of religious and political motives encouraged the indigenous peoples of Libya to resist Italian control vigorously, in what should be understood as another theatre of the First World War. Examining the actions and objectives of anti-colonial leaders as well as Italian policies and practices help explain the weakness of Italian colonial control in Libya. At one stage Italy feared an Islamic insurrection might also break out in their East African colonies. Anti-colonial resistance, real or feared, placed a great strain on relatively scarce Italian resources which were needed in other theatres.
