The element of "consciousness" is all-important. There are, for example, members of the Finnish race scattered all over northern Russia, but they evince no consciousness of any kind that they are allied to the nationality which inhabits the country of Finland. Again, it is only within recent years that the Serbs and the Croats in the south-west corner of the Austro-Hungarian Empire have begun to realise that the only things which divide them one from the other are a difference of religion and a difference of alphabet; and now that the realisation of this fact has spread from the study to the market-place, we see the formation of a new nationality, that of the Serbo-Croats. The researches of historians and other learned men have done an immense deal to stimulate the development of nationalities during the past century, but they are unable of themselves to create them. The fact of kinship is not enough; community of language, customs, and culture is not even enough; to be a real nationality a people must be conscious of all these things, and not merely conscious, but sufficiently conscious to preserve them and, if need be, to die for them. Now the interesting thing for us about a nationality is that it is always striving to become a _nation_. A nation, as we have seen, may be composed of several nationalities; but such cases are rare, and are due to peculiar geographical conditions, as for example in Switzerland and Great Britain, or to external pressure, as in Belgium, which have as it were welded together the different racial elements into a single whole. In general, therefore, a nation is simply a nationality which has acquired self-government; it is nationality _plus_ State. "Ireland a nation," the warcry of the Irish Nationalist party, is a claim, not a statement of fact; Ireland will become a nation when its desire for self-government is satisfied. The case is instructive because it shows that it is not necessary for a nationality to become a _sovereign_ State in order to be in the full sense of the word a nation. It is perfectly possible, as our Serb remarked, for several nations to form a single sovereign state; but as a general rule all such nations will be allowed to manage their own internal affairs. The self-governing Dominions of the British Empire and the Magyars of Hungary are nations, though they are subordinate to their respective imperial governments in questions of peace and war, treaty obligations, etc.
