fiting these territories and of drawing them closer to the rest of the country by the afflux of students from other parts of it, an aim which was realized. Indeed the non-local character of the German Universities, each serving the whole of the lands wherein the German tongue was spoken, powerfully contributed to intensify the sentiment of a common German nationality throughout the two centuries (1648 to 1870) during which Germany had virtually ceased to be a State. The Olympian, Pythian, Isthmian, and Nemean games had no contemptible effect in fostering the sentiment of a common national unity, as against the barbarians, among the Greeks, who had never enjoyed and did not desire political union. The admission of the Macedonian king to strive at the Olympian games was a political event of high significance, for it enabled his descendants Philip and Alexander the Great to claim to belong to the Hellenic race.

Some of these various engines for promoting the cohesion of a nation may seem to lie rather in the sphere of governmental action than in that of a Constitution. Commercial freedom, however, as well as religious compulsion on the one hand, or religious freedom on the other hand, have been provided for by some Rigid Constitutions. So too has been the use of certain languages. Where the Constitution is a Flexible one, the question whether the laws regulating such matters are to be deemed a part of the Constitution depends entirely on the practical importance ascribed to them, since in such a Constitution there is no distinction of form between fundamental and other provisions.

IV. How CONSTITUTIONS MAY REDUCE OR REGULATE THE CENTRIFUGAL FORCES.

Now let us see what Constitutions may effect in the other of the two above specified ways, viz. what they may do to meet and grapple with, and if possible disarm,

the tendencies which make for disruption, i.e. the forces which, while drawing men together in minor groups within the State, are as regards the State itself centrifugal forces.

What are these tendencies? History tells us that the chief among them are race feeling, resentment for past injuries, grievances in respect of real or supposed illtreatment in matters of industry, or of trade, or of education, or of language, or of religion, where these grievances or any of them press on a part only of the population. If they press on the whole population, or on the humbler classes as a whole, they are perturbing, but not necessarily nor even probably disruptive, i.e. they threaten disaffection or a general revolt against the government, rather than the severance of a particular province or the secession of a particular section of the people. It is only with grievances which affect one section or district, and make it desire an independence to be obtained by separation, that we have here to deal. There must be in every such case either a sentiment of dislike on the part of the disaffected section towards the rest of the nation, or else a belief that great material advantages will be obtained by separation; and the latter of these causes is almost sure to produce the former. When two or more of these tendencies combine in any given case, so much the stronger does the desire for separation become.

A few illustrations will explain better than a long abstract statement what I desire to convey. In the ancient world the thing which we call National Sentiment was seldom a powerful factor, perhaps because the more advanced peoples were divided into small city communities, while the backward peoples, living under large empires like the Persian or that of the Seleucid kings, were allowed to retain their own customs and religion, and often their native princes, feeling the weight of subjection only in having to pay tribute and send a contingent in war. The only nations that gave much trouble to the

Achaemenid kings of Persia were the Egyptians, a race very peculiar and very conceited, and the Greeks of Asia Minor. Under the Roman Empire there were wonderfully few national revolts, probably because the imperial government pressed equally upon all, conceded rights of citizenship pretty freely, and gave the subjects in exchange for their own national sentiment the higher pride of belonging to the majestic World State which had engulfed them. The chief source of disruptive attempts lay in the monotheistic religions. The Jews made more than one obviously hopeless rebellion. When Christianity became the religion of the Empire, schisms and heresies gave trouble. Africa was convulsed by the Donatist movement. Egypt was disaffected owing to Monophysitism, and no doubt gave herself the more readily to the Arab conquerors in respect of this disaffection. The persecuted Montanist sectaries of Phrygia revolted in the sixth century. It was the religious persecution of the Fire-worshipping Sassanid kings that provoked their Armenian vassals to rebellion 1. So in the fifteenth and sixteenth centuries, the sentiment of nationality having not yet reached its full strength, it was chiefly by religious divisions that the unity of States was threatened. This was what lost the Dutch Netherlands to Spain. This was what split up the RomanoGermanic Empire, and made it, after the Thirty Years' War, the mere shadow of a State. It contributed to keep the Highlanders distinct from the Lowland population of Scotland after the Reformation (though other causes also were at work), and it was of course a still more potent force in Ireland. In our own time it nearly rent Switzerland in two in the war of the Sonderbund. Conversely, any one who notices how little the unity of the nation has been threatened in Spain, a country where the populations and dialects of the different provinces still present striking contrasts, and are accom

panied by diversities of character, will be disposed to attribute this fact not merely to the absence of natural boundaries between the provinces, but also to the remarkable religious unity which the nation has always. preserved.

In our own time, while religion is a less energetic factor, what is called national sentiment has begun to threaten loosely compacted States. It compelled the transformation in 1868 of the so-called Austrian Empire into the present Dual Monarchy. It shakes the Austrian half of that monarchy now, so sharp is the antagonism between the Czechs of Bohemia and the other Slavic populations of Cis-Leithania and the Germans of the Western and South-Western Crown Lands. Iceland differs from Denmark, with which she has been politically united since 1380 (or 1397), in language, in character, and in habits, and she has therefore struggled for autonomy, a large measure of which she obtained in 1874. She has had some economic grievances, but sentiment has been an even stronger element in her discontent, which, however, stopped short of a wish to separate, as she feels herself too small to stand alone. A strong party in Norway has desired to be divorced from Sweden, to which she was unnaturally yoked in 1814 by the Congress of Vienna, not merely in respect of specific complaints regarding the Foreign Office and the consular service, but also because her people, though Lutherans like the Swedes, are far more democratic in ideas and temper than the latter, and because their high national pride makes them unwilling to appear to be in any way subordinate to the sister kingdom. The case of Poland is a simple one, because she has the memory of an independent kingdom destroyed by force and fraud, and is different in religion, as well as in speech, from the Russians who have annexed her. Had the peasant population of the country shared the patriotism of the upper and middle classes, Poland might possibly have succeeded in shaking off the yoke. Even now her disaffec

tion is a source of weakness to Russia. In Ireland several currents of discontent have joined to produce the passion and prolong the struggle for autonomy, or, in a very few of the more ardent minds, for independence. There is the diversity of faith, which remains, though that of language has almost vanished, a diversity embittered by recollections of persecution. There are economic grievances, the memory of the destruction of an industry in the last century, the more urgent resentment at the exactions of landlords, and the peasants' desire to have a grip of the soil. There is an incompatibility of character and temperament, due partly to historical conditions, partly to the old antagonism of Celt and Teuton. All these have gone to create a passion among the people to be recognized as a nation controlling its own affairs, a passion which is the same in essence among those who would be content with the possession of a subordinate legislature, and those, now fewer than formerly, who would like to go further.

If the sources of the centrifugal force in Ireland are easily explicable, and indeed so strong that had this force acted upon the whole nation instead of only upon a majority which consists mainly of the poorer and weaker part of the population, it would have before now prevailed, those which induced the secession of the Southern States of America are much less evident. Here there was no religious factor, nor any revengeful feeling, nor any sense of an unjust or oppressive control. The South had obtained more than its fair share of power and influence in the councils of the Union. But the planters had persuaded themselves that property in slaves and the whole slave-holding system were threatened by the growing strength in the Northern and Western States of an aversion to slavery, with a determination to check its extension; and the irritation of feeling which a long struggle had engendered, coupled with a growing dissimilarity of habits and ideas, enabled the hot-headed oligarchy which controlled the Southern
