Despite a major revolt by the Arabs, the Ottoman sultan ceded Libya to the Italians by signing the 1912 Treaty of Lausanne. The Italians made extensive use of the Savari, colonial cavalry troops raised in December 1912. These units were recruited from the Arab-Berber population of Libya following the initial Italian occupation in 1911–12. The Savari, like the Spahi or mounted Libyan police, formed part of the "Regio Corpo Truppe Coloniali della Libia" (Royal Corps of Libyan Colonial Troops).
