The coastal parts of Italian Libya became an integral part of Italy under a law of 9 January 1939, and Libya came to be called "the Fourth Shore of Italy" ("Quarta Sponda"). Libyans were given "Special Italian Citizenship" that was only valid within Libya. Libyans were allowed join the Muslim Association of the Lictor, a branch of the National Fascist Party. This allowed the creation of Libyan military units within the Italian army: the 1st Sibille and 2nd Pescatori The units had Italian officers with Libyan NCOs and soldiers. The Libyan divisions were loyal to Italy and performed well in combat. Squadrons of Libyan Spahis served as light cavalry. These measures reduced the appeal of the Libyan resistance movement and kept it mostly limited to Fezzan, and even there it remained weak before the arrival of Free French troops in the area. Beginning in the late 1930s, Libyan Jews faced the persecution of the Holocaust in Libya.
