For the preceding reasons, it is in general a necessary condition of free institutions that the boundaries of governments should coincide in the main with those of nationalities. But several considerations are liable to conflict in practice with this general principle. In the first place, its application is often precluded by geographical hindrances. There are parts even of Europe in which different nationalities are so locally intermingled that it is not practicable for them to be under separate governments. The population of Hungary is composed of Magyars, Slovaks, Croats, Serbs, Roumans, and in some districts Germans, so mixed up as to be incapable of local separation; and there is no course open to them but to make a virtue of necessity, and reconcile themselves to living together under equal rights and laws. Their community of servitude, which dates only from the destruction of Hungarian independence in 1849, seems to be ripening and disposing them for such an equal union. The German colony of East Prussia is cut off from Germany by part of the ancient Poland, and being too weak to maintain separate independence, must, if geographical continuity is to be maintained, be either under a non-German government, or the intervening Polish territory must be under a German one. Another considerable region in which the dominant element of the population is German, the provinces of Courland, Esthonia, and Livonia, is condemned by its local situation to form part of a Slavonian state. In Eastern Germany itself there is a large Slavonic population; Bohemia is principally Slavonic, Silesia and other districts partially so. The most united country in Europe, France, is far from being homogeneous: independently of the fragments of foreign nationalities at its remote extremities, it consists, as language and history prove, of two portions, one occupied almost exclusively by a Gallo-Roman population, while in the other the Frankish, Burgundian, and other Teutonic races form a considerable ingredient.
