The history of the Dual Monarchy during his reign is told under the heading of AUSTRIA-HUNGARY, and here it is only necessary to deal with its personal aspects. The young emperor was during the first years of his reign completely in the hands of Prince Felix Schwarzenberg, to whom, with Windischgraetz and Radetzky, he owed it that Austria had emerged from the revolution apparently stronger than it had been before. The first task was to reduce Hungary to obedience, for the Magyars refused to acknowledge the validity of the abdication in so far as it concerned Hungary, on the ground that such an act would only be valid with the consent of the Hungarian parliament. A further motive for their attitude was that Francis Joseph, unlike his predecessor, had not taken the oath to observe the Hungarian constitution, which it was the avowed object of Schwarzenberg to overthrow. In the war which followed the emperor himself took part, but it was not brought to a successful conclusion till the help of the Russians had been called in. Hungary, deprived of her ancient constitution, became an integral part of the Austrian empire. The new reign began, therefore, under sinister omens, with the suppression of liberty in Italy, Hungary and Germany. In 1853 a Hungarian named Lebenyi attempted to assassinate the emperor, and succeeded in inflicting a serious wound with a knife. With the death of Schwarzenberg in 1852 the personal government of the emperor really began, and with it that long series of experiments of which Austria has been the subject. Generally it may be said that throughout his long reign Francis Joseph remained the real ruler of his dominions; he not only kept in his hands the appointment and dismissal of his ministers, but himself directed their policy, and owing to the great knowledge of affairs, the unremitting diligence and clearness of apprehension, to which all who transacted business with him have borne testimony, he was able to keep a very real control even of the details of government.
