Succeeding Bismarck came German statesmen who were not so steady as he, and their weaker hold on the situation added to the gravity of the prospects of peace. It can hardly be doubted that the fall of Bismarck lessened the prospect that Europe would remain at peace. The Balance of Power, which took so clear a form with the organization of the Dual Alliance, was not as good a guarantee of peace as it seemed; for while it made the checking of powers by powers more apparent, its very existence was evidence of a state of stronger rivalry of nations than existed before the Dual Alliance was formed. At the same time the men who now guided the fortunes of Germany were not so convinced as Bismarck that the country should have peace. While these things happened Great Britain remained generally neutral. She was busy with trade expansion and the development of her colonies, especially in Africa; and her chief interest, so far as the schemes of the Continental nations were concerned, was to see that none of them interfered with her progress in that field of endeavor. Late in Bismarck’s time, however, she became convinced that Germany was becoming a rival both in trade and colonization. It is true that France was also a rival, and between her and Great Britain occurred some sharp passages; but France was not an aggressive nation and had no strong military resources to back her ambitions in the field of peaceful activities. Germany, on the other hand, was increasingly militaristic and the logic of events seemed to indicate that she would at some time in the future be willing to support her commercial and colonial ambition with a formidable appeal to arms. British anxiety was quickened when the young kaiser began to build a great navy, with the avowed object of making it equal to the British navy. For centuries it had been the key-note of British policy to have a navy that could control the seas; and while there was nothing in the will of Father Adam that gave Britons the dominion of the seas, the kaiser must have known that he could not challenge their superiority on water without arousing their gravest apprehension. During the Boer war (1899-1902) Germany gave added offense to Britain. She showed sympathy openly for the Boers, and it was generally believed in Great Britain that she took advantage of the opportunity to try to form a grand alliance to curb the power of the “Mistress of the Seas.” Rumor said that the plan was defeated only by the refusal of France to lend her assistance unless she received Alsace-Lorraine. If the report is true, it only shows what a costly thing to Germany was the hatred that Bismarck created when he put France to the humiliating dismemberment of 1871.
