In March 1910 an Albanian insurrection broke out in Kosovo. In August Montenegro followed Bulgaria's precedent by becoming a kingdom. In 1911 Italy launched an invasion of Tripolitania, which was quickly followed by the occupation of the Dodecanese Islands. The Italians' decisive military victories over the Ottoman Empire greatly influenced the Balkan states to prepare for war against Turkey. Thus, in the spring of 1912 consultations among the various Christian Balkan nations resulted in a network of military alliances that became known as the Balkan League. The Great Powers, most notably France and Austria-Hungary, reacted to this diplomatic sensation by trying to dissuade the League from going to war, but failed.
