Problem: Following the conquest of the temple fort , later known as Jaromarsburg, on Arkona in 1168 by the Danes under King Valdemar I and Bishop Absalon of Roeskilde, the princes of Rugen had to recognise Danish suzerainty. On their accession to power, the Rugen princes were forced to confirm their allegiance to the Danish king and were obliged to provide military support to the Danes. In 1304 Vitslav III of Rugen gained sole lordship over the territory on the death of his brother, Sambor. Because he had no issue at that point in time, there existed the possibility that Rugen's princely house could become extinct. As a result, in 1310 he agreed a contract of inheritance at Ribnitz with the Danish king, Eric VI Menved, his feudal lord. The agreement was that in the event of Vitslav dying without issue, the fiefdom of Rugen would be returned to the Danish crown. At that time, Eric VI Menved was attempting to extend his power in the southern Baltic Sea region in order to reduce the influence of Hanseatic towns like Stralsund. To assist him, in addition to the princes of Rugen, the king also had Prince Henry II of Mecklenburg as a vassal. After the death of Eric VI Menved in 1319, the 1310 treaty lapsed and Vitslav III sought allies in the Pomeranian dukes. On 5 May 1321 dukes Otto I of Pomerania, Vartislav IV of Pomerania-Wolgast and Barnim II of Pomerania-Stettin agreed a mutual inheritance contract with Vitslav III of Rugen. But in an alliance agreement that had been previously concluded on 25 October 1315 between Vartislav IV, the son of Vitslav's sister, Margaret, and Eric's brother, Christopher of Halland, who later became King Christopher II of Denmark, Vartislav IV had already been promised the Rugen fiefdom.

Problem: The Arabs and Turks, estimated at 15,000, made frequent attacks by day and night on the strongly entrenched Italian garrison in the southern suburbs of Benghazi. The four Italian regiments of infantry acted on the defensive and were supported by the San Marco and Agordat. The Italians rarely attempted a sortie. An attack of 20,000 Turkish and local troops was repulsed on November 30 with considerable losses. Shortly after this the garrison was reinforced by the 57th infantry regiment from Italy. The battleship Regina Elena also arrived from Tobruk. During the night of December 14 and 15 the Turks attacked in great force, but were repulsed with aid of the fire from the ships. The Italians lost several field guns. At Derna the Turks and Arabs were estimated at 3,500, but they were being constantly reinforced and a general assault on the Italian position was expected. The Italian and Turkish forces in Tripoli and Cyrenaica were constantly reinforced. The withdrawal of the Turks into the interior enabled them to reinforce their troops considerably. The cost of the war was defrayed chiefly by voluntary offerings from Muslims. Turkish officers and men, weapons, ammunition, and all kinds of supplies were constantly sent across the Egyptian and Tunisian frontiers, notwithstanding their neutrality. The Italians occupied Sidi Barrani on the coast between Tobruk and Solum to prevent contraband and troops from entering across the Egyptian frontier, while the naval blockaders guarded the coast and captured several sailing ships with contraband.
