The liberation of Serbia from the Turkish dominion and its establishment as an independent state were matters of much slower and more arduous accomplishment than were the same processes in the other Balkan countries. One reason for this was that Serbia by its peculiar geographical position was cut off from outside help. It was easy for the western powers to help Greece with their fleets, and for Russia to help Rumania and, later, Bulgaria directly with its army, because communication between them was easy. But Serbia on the one hand was separated from the sea, first by Dalmatia, which was always in foreign possession, and then by Bosnia, Hercegovina, and the _sandjak_ (or province) of Novi-Pazar, all of which territories, though ethnically Serb, were strongholds of Turkish influence owing to their large Mohammedan population. The energies of Montenegro, also cut off from the sea by Dalmatia and Turkey, were absorbed in self-defence, though it gave Serbia all the support which its size permitted. Communication, on the other hand, between Russia and Serbia was too difficult to permit of military help being rapidly and effectively brought to bear upon the Turks from that quarter. Bessarabia, Wallachia, and Moldavia were then still under Turkish control, and either they had to be traversed or the Danube had to be navigated from its mouth upwards through Turkish territory. The only country which could have helped Serbia was Austria, but as it was against their best interests to do so, the Austrians naturally did all they could not to advance, but to retard the Serbian cause. As a result of all this Serbia, in her long struggle against the Turks, had to rely principally on its own resources, though Russian diplomacy several times saved the renascent country from disaster. Another reason for the slowness of the emancipation and development of modern Serbia has been the proneness of its people to internal dissension. There was no national dynasty on whom the leadership of the country would naturally devolve after the first successful revolution against Turkish rule, there was not even any aristocracy left, and no foreign ruler was ever asked for by the Serbs or was ever imposed on them by the other nations as in the case of Greece, Rumania, and Bulgaria. On the other hand the rising against Turkey was a rising of the whole people, and it was almost inevitable that as soon as some measure of independence was gained the unity the Serbs had shown when fighting against their oppressors should dissolve and be replaced by bitter rivalries and disputes amongst the various local leaders who had become prominent during the rebellion. These rivalries early in the nineteenth century resolved themselves into a blood-feud between two families, the Karagjorgjević and the Obrenović, a quarrel that filled Serbian history and militated against the progress of the Serb people throughout the nineteenth century.
