Most of the league leaders held high positions in, or were influential members of, the ruling Turkish elite and were fully aware of the shaky position of the Ottoman Empire; they therefore demanded from the Turks administrative and cultural autonomy for all Albanian lands united in a principality. The Turkish government refused and in 1881 forced the dissolution of the league. Meanwhile, Russia, Italy, and Austria-Hungary began to take an active interest in Albania. Russia aimed at blocking expansion of Austrian influence in the Balkans and supported the territorial demands of Serbia and Montenegro. Italy and Austria-Hungary, on the other hand, concerned over Russia's influence extending to the Adriatic, attempted to influence developments in Albania. The advent of the Young Turks regime (1908), in whose establishment Albanian officials in the service of the empire played a major role, encouraged the Albanians to found cultural and political clubs for the propagation of Albanian culture and the defense of Albanian rights. In 1908 a congress of intellectuals from all parts of Albania and the Albanian colonies abroad, especially the Italo-Albanian colonies in Italy, convened in Monastir (Bitolj) to decide on an Albanian alphabet; it adopted the Latin one as most suitable for the country. This decision marked a great advance toward Albanian unification and eventual statehood. In the summer and fall of 1912, while Serbia, Bulgaria, Montenegro, and Greece, prodded by Russia, were waging war against Turkey, the Albanians staged a series of revolts and began to agitate for the creation of an autonomous and neutral Albania. Accordingly, a group of Albanian patriots, led by Ismail Qemal bey Vlora, a member of the Turkish Parliament, proclaimed Albania's independence at Vlore on November 28, 1912, and organized an Albanian provisional government. Supported by Austria and Italy, Albania's independence was recognized on December 12, 1912, by the London Conference of Ambassadors, but its boundaries were to be determined later. In March 1913 agreement was reached on the northern frontiers, assigning Shkoder to Albania but giving Kosovo and Metohija (Kosmet), inhabited then chiefly by Albanians, to Serbia. This frontier demarcation was very similar to the frontiers between Yugoslavia and Albania as they existed in 1970.
