The special feature in the history of the house of Austria from the fifteenth century onwards is its connexion—a connexion more or less broken, but still constantly recurring till in the end it becomes fully permanent—with the kingdom of Bohemia within the Empire and with the kingdom of Hungary beyond its bounds. These possessions have given the Austrian power its special character, that of a power formed by the union under one prince of several wholly distinct nations or parts of nations which have no tie beyond that union. The Austrian princes, originally purely German, equally in their Swabian and in their Austrian possessions, had already, by the extension of their power to the south, obtained some Slavonic and some Italian-speaking subjects. Still, as a power, they were purely German. ♦Various acquisitions of Austria.♦ But in the period which begins in the fifteenth and goes on into the nineteenth century, we shall see them gradually gathering together, sometimes gaining, sometimes losing—gaining and losing by every process, warlike and peaceful, by which territory can be gained or lost—a crowd of kingdoms, duchies, and counties, scattered over all parts of Europe from Flanders to Transsilvania. But it is the acquisition of the two crowns of Bohemia and Hungary which, above all others, gave the House of Austria its special position as a middle power, a power belonging at once to the system of Western and to the system of Eastern Europe. Among the endless shiftings of the states which have been massed together under the rule of the House of Habsburg, that house has more than once been at the same moment the neighbour of the Gaul and the neighbour of the Turk; and it has sometimes found Gaul and Turk arrayed together against it. Add to all this that, though the connexion between the house of Austria and the Empire was a purely personal one, renewed in each generation by a special election, still the fact that so many kings of Hungary and archdukes of Austria were chosen Emperors one after another, caused the house itself, after the Empire was abolished, to look in the eyes of many like a continuation of the power which had come to an end. The peculiar position of the Austrian house could hardly have been obtained by a mere union of Hungary, Austria, and the other states under princes none of whom were raised to Imperial rank. Nor could it have been obtained by a series of mere dukes of Austria, even though they had been chosen Emperors from generation to generation. It was through the accidental union under one sovereign of a crowd of states which had no natural connexion with each other, and through the further accident that the Empire itself seemed to become a possession of the House, that the House of Habsburg, and its representative the House of Lorraine, have won their unique position among European powers.
