Since 1871 the object of every Prussian Government had been to reconcile the German people to the veiled rule of the sword by exhibiting results which, it was contended, could not otherwise have been secured. Historians dwelt on the failure of the German Parliament at Frankfurt to promote a national unity which was left for Prussian arms to achieve, and philosophers deduced from that example a comprehensive creed of might. More material arguments were provided for the man in business and in the street by the skilful activities of the Government in promoting trade, industry, and social welfare; and the wealth, which would in any case have accrued from the removal of the tariff-walls and other barriers between the thirty-nine independent States of Germany, was credited to the particular method of war by which the unification had been accomplished. No State had hitherto made such economic progress as did the German Empire in the generation after Metz and Sedan, and the success of their rulers led most of the German people to place implicit reliance on the testimony those rulers bore to the virtue of their means. The means did not, however, commend themselves to the rest of the world with equal conviction; and an increasing aversion to the mailed fist on the part of other countries led to what Germans called the hostile encirclement of their Fatherland. Gradually it became clearer that Prussian autocracy could not reproduce in the sphere of world-ambitions the success which had attended it in Germany unless it could reduce the world to the same submission by the use of similar arguments.
