The Serbs divided into many parties, each with rival leaders. Russia, who had supported Karageorge, was now herself engaged in a life and death struggle with Napoleon. The Russian regiment which had been quartered at Belgrade, left the country. The turn of the Turks had now come. They attacked the Serbs in force. With no aid from without to be hoped for, the country was in greater danger than ever. But even common danger, as history has again and again shown, does not suffice to cure that fatal Slav weakness--the tendency to split into rival parties led by jealous chieftains. There was no union among the Serb forces now, at the very hour when it was most needed. And for some never explained reason Karageorge failed to appear. His Voyvodas struggled with the foe and were beaten back and suddenly, in October 1813, Karageorge, the chosen leader of the Serbian people, fled into Austria with a few followers, without even having struck a blow. This tragic and most fatal failure was due in all probability, to a mental collapse to which his unstable and unbalanced nature would be peculiarly liable. The Austrians promptly interned both him and his men in fortresses, but released them at the intercession of Russia, and they retired into Bessarabia. Meanwhile, his place was taken by Milosh Obrenovitch, also a peasant, who led the Serb rising of 1815 with such success that he was recognized as ruler, under Turkish suzerainty, of a considerable territory. And as a ruler, moreover, with hereditary rights. It is said that Russia never forgave the Obrenovitches that they were appointed by the Sultan and not by herself. Scarcely was Milosh well established when Karageorge returned from his long absence. The break-up of the Turkish Empire had begun. The Greeks were in a ferment. Russia supported them. The Hetairia had been formed and a plan was afoot for a great simultaneous rising of Greeks and Serbs and Roumanians. Karageorge was to be one of its leaders. But Milosh was in power, id did not mean to relinquish it. And he dreamed already of wide empire. He examined the question with sangfroid and decided that if the Greek revolution succeeded in its hopes, an Empire would be reborn in the East which would regard Serbia as its province and might be more dangerous than the Turk. Did not the Greeks, in the fourteenth century, call the Turks to Europe to fight the "Tsar of Macedonia who loves Christ?" Milosh remained faithful to the Turk, saying "Let us remain in Turkey and profit by her mistakes." He suppressed all pro-Greek action, executed twenty pro-Greek conspirators, and exposed their bodies at the roadside, and--in an evil hour for Serbia--had Karageorge assassinated and sent his head to the Pasha. From that day onward the feud between the two houses raged with ever increasing fury. Until to-day every ruler of Serbia has been either exiled, murdered, or has had his life attempted.
