Defence, too, assumed a more anxious {141} aspect. The nations of Europe were entering on a mad scramble for empire, for colonial possessions overseas. Russia pushed steadily westward to the Pacific and south to the gates of India. France sought territory in Africa and in Asia, Germany in Africa and the Pacific, Italy in Africa. Nationalism had gone to seed in imperialism. Long prevented by internal dissensions from competing with England in the acquisition of territory, the nations of Europe, now that national consolidation had been largely effected, turned to follow her example. England could not logically object to their desire for territory or to their plans for larger navies. Her Palmerstons and Disraelis had boasted of the might of the empire on which the sun never set; her Froudes and Seeleys were singing the glories of the 'expansion of England'; the man in the street felt the manifest destiny of the Anglo-Saxon to rule the 'lesser breeds'; while the American Mahan had made clear the importance of sea-power and had pointed the means to the end so glorified. None the less the rivalry was felt uncomfortable, the more so as these nations did not follow Britain's free-trade policy in their new possessions, and sometimes manifested a lack of {142} scruple which boded ill for future peace. And so from some quarters in Britain came the demand for colonial contributions to the Army and Navy, or failing that, for some form of imperial federation which would set up a central parliament with power to tax and to control. In August 1886 an influential deputation from the Imperial Federation League waited upon the prime minister, Lord Salisbury, and asked him to summon a conference of all the colonies to discuss the idea of setting up a federal council as a first step towards centralizing authority. The prime minister expressed his doubt as to the wisdom of discussing political changes which, if possible, were so only in the distant future. Believing, however, that there were other subjects ripe for discussion, he took the momentous step, and called the first Colonial Conference. Every self-governing colony and several crown colonies sent representatives. Canada sent Sir Alexander Campbell, lieutenant-governor of Ontario, and Mr, later Sir Sandford, Fleming, the apostle of an All-Red Pacific cable. Lord Salisbury, in opening the proceedings, referred to the three lines upon which progress might be made. The German {143} Empire evidently suggested the ideas which he and others had in mind. A political federation, like that of Germany, to conduct 'all our imperial affairs from one centre,' could not be created for the present. But Germany had had two preliminary forms of union, both of which might be possible, a _zollverein_ or customs union, not yet practicable, and a _kriegsverein_, or union for purposes of mutual defence, which was feasible, and was the real and important business before the Conference.
