One further factor in French tariff policy during this period was the Treaty of Frankfurt (1871) terminating the war of 187o-71. By that treaty France and Germany had guaranteed each other most-favoured-nation treatment,—not complete, but almost com plete, in that they guaranteed to each other the same rates as they conceded to the important neighbouring countries of central Eu rope. Being incorporated in the general treaty, these provisions, un like the special commercial treaty of 1860 with England, could not be denounced; and they were felt by both countries to hamper their commercial negotiations, being the more unwelcome because of the constantly growing national antagonism. When all treaties and engagements with Germany, and practically those with other countries also, were swept away with the World War, France was able to proceed untrammelled with a new course of policy. It rested upon the maintenance of a high protective system, suscep tible of some liberalization through special bargains with other countries, by which these were to be induced to admit French goods at lowered rates in exchange for specified concessions in the French duties, varying from country to country. In 192o the
maximum and minimum system was virtually given up and the government given free hand in commercial negotiations. The result was a highly complicated series of engagements, which brought into vivid contrast two essentially different lines of policy: that of special bargaining, and that of equal treatment under a most-favoured-nation clause. The second policy was unpopular in France, partly because of its association with the Treaty of Frank furt, but partly for other reasons connected with peculiarities of French foreign trade. Not only as regards France, but as re gards Europe at large, the alignment was marked by one or the other of these two ways of procedure. Those in favour of closer commercial relations preferred the most-favoured-nation method, while high protectionists looked to the policy of specific bargain ings. On the whole France was not successful in securing what she wished by bargaining, even though she had political advan tages in dealing with States like Czechoslovakia, Hungary, Yugo slavia, and even Belgium. In 1927 she was compelled to arrange with Germany a treaty virtually upon most-favoured-nation basis, a change which marked a halt in the other policy, and perhaps the beginning of a general trend the other way.
But after 1871 Germany, like France, and at about the same time, turned the other way. Under Bismarck's lead, and in consequence of an alliance between the industrialists of the west and south and the agricultural interests of the east (now threatened by imports), Germany returned in 1879 to protection. Grain duties were imposed, and proved an important source of revenue, be cause imports continued on a large scale ; at the same time the continuing imports made the landed interest firmly protectionist At the beginning of 1892 Germany entered upon a policy of com mercial treaties which were based upon special negotiation with each particular country ; though they were prevented by the treaty of Frankfurt from having as much effect in the way of dis criminations between countries as might otherwise have been the case. This policy of specialization was continued in the legisla tion of 5902, when rates were further increased and further com mercial treaties were initiated. As in the case of France, the policy of specialized commercial negotiations led to quarrels and retali ations, there being tariff wars with Russia, Spain and Canada. After the World War, Germany for a while was restricted by cer tain provisions of the Versailles Treaty. These required her for five years from the date of the treaty (that is, during 1919-24) to give most-favoured-nation treatment to the Allies, while at the same time leaving the Allies free. With the termination of this arrangement in 1924 Germany proceeded more freely, and in 1925 adopted a new tariff. A protectionist regime was established both for agricultural products and for manufactured goods, with an ex pectation, however, that the duties might be reduced through bar gaining for lower duties by other countries on German goods. Success in this direction was achieved in 1927 by the commercial treaty with France, which provided for certain reductions upon French goods, and also secured for German goods imported into France treatment virtually on a most-favoured-nation basis. Other treaties contained similar provisions, and emphasized the acceptance by Germany of the most-favoured-nation policy and disposition to moderate the protectionist regime.
