century ago, will call many nations into being; the first and not the least of her creations is a transfigured and united Belgium. [Footnote 1: _Cambridge Modern History_, vol. x. p. 521.] [Footnote 2: _Ibid_. vol. xi. p. 693.] As a frontier State, a link between the Latin and Teutonic races to both of which her peoples are akin, Belgium offers an extremely interesting study of the national idea at work. The peoples of Germany and France, which have been perpetually at war with each other since the times of Julius Caesar, have almost always met on her fair and prosperous plains to fight their battles, since she is geographically the gateway from one to the other. Neither could afford to let the other occupy her territory, and so she has won her independence as a State; both have constantly threatened her existence in times past, and so have forced upon her bi-lingual population that consciousness of common interests which if strong enough may become as firm a basis for national unity as actual community of nationality. It should be noticed further that it has become the practice in recent times to guarantee the neutrality of small frontier States like Belgium which lie at the mercy of their greater neighbours, a practice intended not only to preserve the integrity of such States but also to prevent the frequent occurrence of war by closing, as it were, the military gate between the hostile countries.[1] It remains to be seen whether the violation of these principles by Germany has the effect of strengthening them in the future, rather than the reverse. In any case, we may expect to see attempts to apply the same principles to other parts of Europe. Already the northern and southern ends of the frontier between Germany and France are neutralised by the existence of Belgium and Switzerland; why, it may be asked, should not the whole frontier be treated in the same way by neutralising the disputed territory of Alsace-Lorraine? Perhaps, too, a neutral Poland would form a useful buffer between Germany and Russia. Such neutralisation, it should be noted, need not necessarily carry with it independence. Poland and Alsace-Lorraine might form part of Russia and France respectively, and still be neutralised by a guarantee of other powers. A precedent exists for this in the terms of the cession of the Ionian Islands to Greece in 1864, while Savoy, though a province of France, is technically neutralised territory.[2] Cases like these, however, it must be admitted, are extremely anomalous and could hardly stand the strain of a serious war. But, then, as recent experience has shown us, not even independent neutralised States are safe when all Europe is aflame. The truth is that the whole conception of neutrality implies the existence of some power above and beyond the State, it may be simply a group of powerful States who are able to impose their will upon the rest of Europe, it may be a general Congress, like the Congress of Vienna.
