A plot on the part of Hungarians to murder Kollar was even discovered. Kollar several times appealed, and appealed successfully, to the Emperor Francis I. for protection. Kollar's ideas of Slavic solidarity also resulted mainly in disappointment. The separation of the Slavs on the whole continued as before, and even Kollar's own language, the Bohemian, was abandoned by Kollar's own countrymen. The Slavs of Northern Hungary, identical in race with the Bohemians and Moravians, had always used the Bohemian language. Šafařik, as well as Kollar himself, both born in the Slavic districts of Hungary, wrote in Bohemian. In the present century only the Slavs of Northern Hungary adopted as a written language a dialect that slightly differs from Bohemian. The result of this injudicious step, which Kollar from the first strongly blamed, has been the almost complete absorption by the Magyars of the isolated Slavs of Northern Hungary. During the Hungarian revolution Kollar left Pest. Like most Slavs, his sympathies were rather with the Austrians than with the Hungarians, who had, indeed, constantly persecuted him. He spent some time travelling in Germany and Italy. One of the results of his visit to the last-named country was that deplorable work, _Staroitalia Slavjanská_ ("Slavic Ancient Italy"). In recognition of his faithfulness to the Austrian Government, Kollar, immediately after the suppression of the Hungarian revolution in 1849, was awarded the professorship of Slavic archaeology at the University of Vienna. He did not live long to enjoy the comparative prosperity of which he was now assured. He died at Vienna on January 24, 1852, leaving his wife and children in a state of great destitution.
