Since 1890 there has been, especially in the neighbourhood of Strassburg, evidence of a spread of national German feeling, probably to a great extent due to the settlement of Germans from across the Rhine. The presence of these anti-German parties, amounting sometimes to one-tenth of the whole, in the Reichstag added greatly to the difficulty of parliamentary government. Gradually, however, as a new generation grew up their influence declined. In the Reichstag of 1907, Guelphs, Alsace-Lorrainers and Danes together could muster only five members. The period 1870 to 1878. The great work since 1870 has been that of building up the institutions of the empire. For the first time in the history of Germany there has been a strong administration ordering, directing and arranging the life of the whole nation. The unification of Germany was not ended by the events of 1866 and 1871; it was only begun. The work has throughout been done by Prussia; it has been the extension of Prussian principles and Prussian administrative energy over the whole of Germany. It naturally falls into two periods; the first, which ends in 1878, is that in which Bismarck depended on the support of the National Liberals. They were the party of union and uniformity. The Conservatives were attached to the older local diversities, and Bismarck had therefore to turn for help to his old enemies, and for some years an alliance was maintained, always precarious but full of results. Legal reform. The great achievement of the first period was legal reform. In nothing else was legislation so much needed. Forty-six districts have been enumerated, each of which enjoyed a separate legal system, and the boundaries of these districts seldom coincided with the frontiers of the states. Everywhere the original source of law was the old German common law, but in each district it had been wholly or partly superseded by codes, text-books and statutes to a great extent founded on the principles of the Roman civil law. Owing to the political divisions, however, this legislation, which reached back to the 14th century, had always been carried out by local authorities. There had never been any effective legislation applicable to the whole nation. There was not a state, not the smallest principality, in which some authoritative but imperfect law or code had not been published. Every free city, even an imperial village, had its own "law," and these exist down to the present time. In Bremen the foundation of the civil code was still the statutes of 1433; in Munich, those of 1347. Most of the states by which these laws had been published had long ago ceased to exist; probably in every case their boundaries had changed, but the laws remained valid (except in those cases in which they had been expressly repealed) for the whole of the district for which they had been originally promulgated. Let us take a particular case. In 1591 a special code was published for the upper county of Katzellenbogen.
