These external changes, these shifting scenes, these various masters and systems of government, naturally affected the internal condition of the country as well. Of the social life of the country, however, we know very little. The chroniclers of the period are monks, or noble ecclesiastics who wrote of, and for their own class, and the people did not enter into their concerns. But the political changes were very great. The Frankish county administrations fell into disuse through the increase of immunities granted to royal and ecclesiastical foundations, by which they were exempted from obedience to the county officers. The counts themselves, who had formerly held office at the sovereign's pleasure, gradually made their dignities into hereditary fiefs, which became family property in wealthy and powerful houses. Thus, at the close of the ninth and the beginning of the tenth century we already find in Switzerland a number of counts, such as the Nellenburger, in Zurichgau; the Lenzburger, in Aargau; the Burkharde, in Chur-Rhætia; the Kyburger, at Winterthur, near Zurich. The greatest changes, however, were effected by the growth of feudalism, which had arisen indeed under Charlemagne, but had to some extent been checked by him. Feudalism outgrew all other systems, and entirely disarranged the social scale. The free peasantry shrank to a small number, and there sprang up a martial nobility of high functionaries, who held offices in the army or courts of justice, and exerted much influence. On the native soil, on the very meeting-places where the old German people had assembled to deal with civil and judicial matters, eminent men founded families which grew into reigning houses. These men, combining political discernment with military ability and experience, rose above their fellows, and assumed the highest offices. The distresses, the dissensions, the intestine wars, and particularly the invasions by savage hordes, drove people to seek the protection of powerful lords, even at the risk of losing their own independence. In most cases the people became "unfree," or serfs. Society thus was divided into distinct classes; the old German democracy gave place to a highly aristocratic order, the nobility ruling over the people. Thus, we find Switzerland, like other European countries, struggling through her age of feudalism, and centuries must yet pass before she succeeds in establishing a system of government which alone will suit her peculiar character.
