(_Zollparlament_) was of little service beyond the limits of its special activity. In the election to the customs parliament in 1868, Württemberg did not return a single deputy who was favourable to the national cause; in Bavaria the anti-nationalists had a large majority; and even in Baden and Hesse-Darmstadt, where the opposition to Prussia was less severe, a powerful minority of the deputies had no liking for Bismarck and his ways. Thus the customs parliament was kept rigidly to the objects for which it was founded, greatly to the disappointment of patriots who had not doubted that it would become an effective instrument for the attainment of far larger purposes. Had the completion of unity depended wholly on internal causes, it certainly would not have been soon achieved; but other forces, not altogether unexpectedly, came to Bismarck's aid. France had been irritated by the enormous increase of Prussian power, and even before the treaty of Prague was signed the emperor Napoleon III. indicated a wish to be "compensated" with the left bank of the Rhine. This was a claim exactly calculated to play into Bismarck's hands. The communication of the French emperor's original proposals to the South German governments, whose traditional policy had been to depend on France to save them from the ambitions of the German great powers, was enough to throw them into the arms of Prussia. The treaties of peace between Prussia and the South German states were accompanied by secret treaties of offensive and defensive alliance, under which the supreme command in war was to be given to the Prussian king. A common war against a common enemy now appeared the surest means of welding the dissevered halves of Germany together, and for this war Bismarck steadily prepared. There were soon plentiful signs of where this enemy was to be sought. On the 14th of March 1867 Thiers in the French Chamber gave voice to the indignation of France at the bungling policy that had suffered the aggrandizement of Prussia. The reply of Bismarck was to publish (March 19) the secret treaties with the South German states. War was now only a question of time, and the study of Bismarck was to bring it on at the moment most favourable to Germany, and by a method that should throw upon France the appearance of being the aggressor. The European situation was highly favourable. France was hampered by the Roman question, which divided her own counsels while it embroiled her with Italy; the Luxemburg question, arising out of her continued demand for "compensation," had only served to isolate her still further in Europe. French patriotic feeling, suspicious, angry and alarmed, needed only a slight provocation to cause it to blaze up into an uncontrollable fever for war. The Hohenzollern candidature.
