In the old Danubian Monarchy political thought was wider in its range and had a richer variety of interests than in the Germany of that epoch--excepting certain parts of Prussia, Hamburg and the districts bordering on the North Sea. When I speak of Austria here I mean that part of the great Habsburg Empire which, by reason of its German population, furnished not only the historic basis for the formation of this State but whose population was for several centuries also the exclusive source of cultural life in that political system whose structure was so artificial. As time went on the stability of the Austrian State and the guarantee of its continued existence depended more and more on the maintenance of this germ-cell of that Habsburg Empire.
