The boundaries in the south were more difficult to delineate because Greece laid claim to most of southern Albania, which the Greeks call Northern Epirus. The Conference of Ambassadors appointed a special commission to draw the demarcation line on ethnographic bases and in December 1913 drafted the Protocol of Florence, which assigned the region to Albania. The 1913 boundaries in the south, like those in the north, were almost the same as those that existed between Greece and Albania in 1970. The Albania that emerged from the Conference of Ambassadors was a truncated one; as many Albanians were left out of the new state as were included in it. The Conference of Ambassadors also drafted a constitution for the new state, which was proclaimed as an autonomous principality, sovereign, and under the guarantees of the Great Powers; created an International Control Commission to control the country's administration and budget; and selected as ruler the German Prince Wilhelm zu Wied. Prince Wied arrived in March 1914 but had to flee the country six months later because of the outbreak of World War I and the difficulties caused by the unruly feudal beys. As a consequence, Albania's independence came to an end, and for the next four years the country served as a battleground for the warring powers. CREATION OF MODERN ALBANIA At the end of World War I Albania was occupied by the Allied armies, mostly Italian and French. The Secret Treaty of London, concluded in 1915 and published by the Russian Bolsheviks after the October 1917 Revolution, provided for the partition of nearly all Albania among Italy, Serbia, Montenegro, and Greece. Another accord, known as the Tittoni-Venizelos Agreement, concluded between Italy and Greece in 1919, also called for the dismemberment of Albania. At the 1919-20 Paris Peace Conference Greece laid claim to southern Albania; Serbia and Montenegro, to the northern part; and Italy, to the port of Vlore and surrounding areas. But President Woodrow Wilson's principle of self-determination and his personal insistence on the restoration of an independent Albania saved the country from partition. In the summer of 1920 an Albanian partisan army drove the Italians from Vlore, and the Italian government recognized Albania's independence. In the meantime, in January 1920 a congress of representatives met in Lushnje, in central Albania, and created a government and a Council of Regency composed of representatives of the four religious denominations prevailing in Albania: the two Muslim sects (Sunni and Bektashi), Roman Catholic, and Eastern Orthodox (see ch. 5, Social System).
