of 1922 the only effective anti-colonial resistance to the occupation was concentrated in the Cyrenaican hinterlands. The Italians subjugated the Libyan people; Cyrenaica's livestock was decimated, a large portion of its population was interned in concentration camps, and between 1930 and 1931 an estimated 12,000 Cyrenaicans were executed by the Regio Esercito (Italian Royal Army). The Italian government implemented a policy of "demographic colonization", by which tens of thousands of Italians were relocated to Libya, largely to establish farms. Following the outbreak of the Second World War in September 1939, Idris supported the United Kingdom—which was now at war with Italy—in the hope of ridding his country of Italian occupation. He argued that even if the Italians were victorious, the situation for the Libyan people would be no different than it had been before the war. Delegates from both the Cyrenaicans and Tripolitanians agreed that Idris should conclude agreements with the British that they would gain independence in return for support during the war. Privately, Idris did not promote the idea of Libyan independence to the British, instead suggesting that it become a British protectorate akin to Transjordan. A Libyan Arab Force, consisting of five infantry battalions made up of volunteers, was established to aid the British war effort. With the exception of one military engagement near to Benghazi, this force's role did not extend beyond support and gendarmerie duties. After the defeat of the Italian armies, Libya was left under the military control of British and French forces. They governed the area until 1949 according to the Hague Convention of 1907. In 1946, a National Congress was established to lay the groundwork for independence; it was dominated by the Senussi Order. Under British and French pressure, Italy relinquished its claim of sovereignty over the country in 1947, although still hoping that they would be permitted a trusteeship over Tripolitania. The European powers drew up the Bevin-Sforza plan, which proposed that France retain a ten-year trusteeship in Fezzan, the UK in Cyrenaica, and Italy in Tripolitania. After the plans were published in May 1949, they generated violent demonstrations in Tripolitania and Cyrenaica and drew protests from the United States, Soviet Union, and other Arab states. In September 1948, the question of Libya's future was brought to the United Nations General Assembly, which rejected the principles of the Bevin-Sforza plan, instead indicating support for full independence. At the time neither the
