Russia had fallen very low after the war with Japan, but was rapidly recovering both in wealth and armed strength. France was making strenuous efforts to increase her army, so that she should not be at a disadvantage as compared with the far greater population of Germany. Britain had no ambitions of conquest; her aim was the peaceful development of her Empire. But that was an oversea Empire, and she required a large navy; and the size of this navy seemed to Germany to be a menace to her future.

The result was that in the summer of 1914 the rulers of Germany had decided that some great effort must soon be made; they must put their land in such a position that for the future it would have no cause to dread the aggression, or even the rivalry, of other Powers. If they delayed too long they feared that the growing wealth of Russia and the increased military strength of France would make such an effort for ever impossible.
