The great position gained by the German empire in these years was won in the face of great and increasing internal difficulties. These difficulties were, in the main, the outcome of the peculiar constitution of the empire, of the singular compromise which it represented between the traditional medieval polity and the organization of a modern state, and of the conflicts of ideals and of interests to which this gave rise; these being complicated by the masterful personality of the emperor William, and his tendency to confuse his position as German emperor by the will of the princes with his position as king of Prussia by the grace of God. In general, Germany had passed since the war through a social and economic revolution similar to that undergone by Great Britain during the earlier half of the 19th century, though on a greater scale and at a much accelerated pace. A country mainly agricultural, and in parts purely feudal, was changed into one of vast industries and of great concentrations of population; and for the ferment created by this change there was no such safety-valve in the representative system as had existed in England since the Reform Bill. In spite of the election of the Reichstag by manhood suffrage, there existed, as Count Bülow pointed out in 1904, no real parliamentary system in Germany, and "owing to the economic, political, social and religious structure of the nation" there could never be one. Of the numerous groups composing the German parliament no one ever secured a majority, and in the absence of such a majority the imperial government, practically independent of parliament, knew how to secure its assent to its measures by a process of bargaining with each group in turn. This system had curious and very far-reaching results. The only group which stood outside it, in avowed hostility to the whole principle on which the constitution was based, was that of the Social Democrats, "the only great party in Germany which," so the veteran Mommsen declared in 1901, "has any claim to political respect." The consequence was the rapid extension and widening of the chasm that divided the German people. The mass of the working-class population in the Protestant parts of Germany belonged to the Social Democracy, an inclusive term covering variations of opinion from the doctrinaire system of Marx to a degree of Radicalism which in England would not be considered a bar to a peerage. To make head against this, openly denounced by the emperor himself as a treasonable movement, the government was from time to time forced to make concessions to the various groups which placed their sectional interests in the forefront of their programmes. To conciliate the Catholic Centre party, numerically the strongest of all, various concessions were from time to time made to the Roman Catholic Church, e.g. the repeal in 1904 of the clause of the Anti-Jesuit Law forbidding the settlement of individual members of the order in Germany.
