The Empire of Germany is a federal union, differing from the United States and Switzerland in having an hereditary emperor as its head. It comprises twenty-six States, who have "formed an eternal union for the protection of the realm, and the care of the welfare of the German people."[63] The King of Prussia, under the title of German Emperor, represents the empire in all its relations to foreign nations, and has the power of making peace and war, but if the war be more than a defensive war he must have the assent of the Upper House. The legislative body of the empire consists of two Houses--the Upper, called the Bundesrath, representing the several component States in different proportions according to their relative importance; the lower, the Reichstag, elected by the voters in 397 electoral districts, which are distributed amongst the constituent States in unequal numbers, regard being had to the population and circumstances of each State. The Austro-Hungarian Empire is a federal union, differing alike in its origin and construction from the federal unions above mentioned. In the beginning Austria and Hungary were independent countries--Austria a despotism, Hungary a constitutional monarchy, with ancient laws and customs dating back to the foundation of the kingdom in 895. In the sixteenth century the supreme power in both countries--that is to say, the despotic monarchy in Austria and the constitutional monarchy in Hungary--became vested in the same person; as might have been anticipated, the union was not a happy one. If we dip into Heeren's _Political System of Europe_ at intervals selected almost at random, the following notices will be found in relation to Austria and Hungary:--Between 1671 and 1700 "political unity in the Austrian monarchy was to have been enforced especially in the principal country (Hungary), for this was regarded as the sole method of establishing power; the consequence was an almost perpetual revolutionary state of affairs."[64] Again, in the next chapter, commenting on the period between 1740 and 1786: "Hungary, in fact the chief, was treated like a conquered province; subjected to the most oppressive commercial restraints, it was regarded as a colony from which Austria exacted what she could for her own advantage. The injurious consequences of this internal discord are evident." Coming to modern times we find that oppression followed oppression with sickening monotony, and that at last the determination of Austria to stamp out the Constitution in Hungary gave rise to the insurrection of 1849, which Austria suppressed with the assistance of Russia, and as a penalty declared the Hungarian Constitution to be forfeited, and thereupon Hungary was incorporated with Austria, as Ireland was incorporated with Great Britain in 1800. Both events were the consequences of unsuccessful rebellions; but the junction which, in the case of Hungary, was enforced by the sword, was
