When Napoleon was sent to St. Helena, the European nations breathed more freely, and it was the general expectation and desire that there would be no more wars. The civilized world was weary of strife and battlefields, and in the reaction which followed the general peace of 1815, the various States settled down into a state of dreamy repose. Not only were they weary of war, but they hated the agitation of those ideas which led to discontent and revolution. The policy of the governments of England, France, Germany, and Russia was pacific and conservative. There was a universal desire to recover wasted energies and develop national resources. Visions of military glory passed away for a time with the enjoyment of peace. Nations reflected on their follies, and resolved to beat their swords into ploughshares.

Then began a period of philanthropy as well as of rest and reaction. Societies were organized, especially in England, to spread the Bible in all lands, to send missionaries to the heathen, and proclaim peace and good-will to all mankind, A new era seemed to dawn upon the world, marked by a desire to cultivate the arts, sciences, and literature; to develop industries, and improve social conditions. War was seen to be barbaric, demoralizing, and exhausting. Peace was hailed with an enthusiasm scarcely less than that which for twenty years had created military heroes. The Holy Alliance was not hypocritical. Although a political compact made under a religious pretext, it was formed by monarchs deeply impressed by the horrors of war, and by the necessity of establishing a new basis for the happiness of mankind on the principles of Christianity, when peace should be the law of nations; at the same time it was formed no less to suppress those ideas which it was supposed led logically to rebellions and revolutions, and to disturb the reign of law, the security of established institutions, and the peaceful pursuit of ordinary avocations. This was the view taken by the Czar Alexander, by Frederick William of Prussia, by Francis I. of Austria, by Louis XVIII. of France, as well as by leading statesmen like Talleyrand, Nesselrode, Hardenberg, Chateaubriand, Metternich, Wellington, and Castlereagh.

But these views were delusive. The world was simply weary of fighting; it was not impressed with a sense of the wickedness, but only of the inexpediency of war, except in case of great national dangers, or to gain what is dearest to enlightened people,--personal liberty and constitutional government.

Consequently, scarcely five years passed away after the fall of Napoleon before Europe was again disturbed by revolutionary passions. There were no international wars. On the whole, England, France, Russia, Prussia, and Austria put aside ambitious designs of further aggrandizement, and were disposed to keep peace with one another; and this desire lasted for a whole generation. But there were other countries in which the flames of insurrection broke out. The Spanish colonies of South America were impatient of the yoke of the mother country, and sought national independence, which they gained after a severe struggle. The disaffection in view of royal despotism reached Spain itself, and a revolution in that country dethroned the Bourbon king, and was suppressed only by the aid of France. All Italy was convulsed by revolutionary ideas and passions growing out of the cruel despotism exercised by the various potentates who ruled that fair but unhappy country. Insurrections were violent in Naples, in Piedmont, and in the papal territories, and were put down not by Italian princes, but by Austrian bayonets. As it is my design to present these in another lecture, I simply allude to them in this connection.

But the most important revolution which occurred at this period, taking into view its ultimate consequences and its various complications, was that of Greece. It was different from those of Spain and Italy in this respect, that it was a struggle not to gain political rights from oppressive rulers, but to secure national independence. As such, it is invested with great interest. Moreover, it was glorious, since it was ultimately successful, after a dreadful contest with Turkey for seven years, during which half of the population was swept away. Greece probably would have succumbed to a powerful empire but for the aid tardily rendered her by foreign Powers,--united in this instance, not to suppress rebellion, but to rescue a noble and gallant people from a cruel despotism.

Had the armed intervention of Russia, England, and France taken place at an earlier period, much suffering and bloodshed might have been averted. But Russia was fettered by the Holy Alliance to suppress all insurrection and attempts at constitutional liberty wherever they might take place, and could not, consistently with the promises given to Austria and Prussia, join in an armed intervention, even in a matter dear to the heart of Alexander, whose religion was that of Greece. The Czar was placed in an awkward position. If he gave assistance to the Greeks, whose religious faith was the same as his own and whose foe was also the traditionary enemy of Russia, he would violate his promises, which he always held sacred, and give umbrage to Austria. The intolerant hatred of Alexander for all insurrections whatever induced him to stand aloof from a contest which jeoparded the stability of thrones, and with which in a political view, as an absolute sovereign, he had no sympathy. On the other hand, if Alexander remained neutral, his faith would be trodden under foot, and that by a power which he detested both politically and religiously,--a power, too, with which Russia had often been at war. If Turkey triumphed in the contest, rebels against a long-constituted authority might indeed be put down; but a hostile power would be strengthened, dangerous to all schemes of Russian aggrandizement. Consequently Alexander was undecided in his policy; yet his indecision tore his mind with anguish, and probably shortened his days. He was, on the whole, a good man; but he was a despot, and did not really know what to do. England and France, again, were weakened by the long wars of Napoleon, and wanted repose. Their sympathies were with the Greeks; but they shielded themselves behind the principles of non-intervention, which were the public law of Europe.

So the poor Greeks were left for six years to struggle alone and unaided against the whole force of the Turkish empire before relief came, when they were on the verge of annihilation. It was the struggle of a little country about half the size of Scotland against an empire four times as large as Great Britain and France combined; of a population less than a million against twenty-five millions. It was more than this: it was, in many important respects, a war between Asia and Europe, kindred in spirit with the old Crusades. It was a war of races and religions, rather than of political principles; and hence it was marked by inhuman atrocities on both sides, reminding us of the old wars between Jews and Syrians. It was a tragedy at which the whole civilized world gazed with blended interest and horror. It was infinitely more fierce than any contest which has taken place in Europe for three hundred years. To the Greeks themselves it was, after the first successes, the most discouraging contest that I know of in human history; and yet it had all those elements of heroism which marked the insurrection of the Hollanders under William the Silent against the combined forces of Austria and Spain. It was grand in its ideas, like our own Revolutionary War; and the liberty which was finally gained was purchased by greater sacrifices than any recorded in any war, either ancient or modern. The war of Italian independence was a mere holiday demonstration in comparison with it. Even the Polish wars against Russia were nothing to it, in the sufferings which were endured and the gallant feats which were performed.

But as Greece was a small and distant country, its memorable contest was not invested with the interest felt for battles on a larger scale, and which more directly affected the interests of other nations. It was not till its complications involved Turkey and Russia in war, and affected the whole "Eastern Question," that its historical importance was seen. It was perhaps only the beginning of a series of wars which may drive the Ottoman Turks out of Europe, and make Constantinople a great prize for future conquerors.

That is unquestionably what Russia wants and covets to-day, and what the other great Powers are determined she shall not have. Possibly Greece may yet be the renewed seat of a Greek empire, under the protection of the Western nations, as a barrier to Russian encroachments around the Black Sea. There is sympathy for the Greeks; none for the Turks. England, France, and Austria can form no lasting alliance with Mohammedans, who may be driven back into Asia,--not by Russians, but by a coalition of the Latin and Gothic races.

It is useless, however, to speculate on the future wars of the world. We only know that offences must needs come so long as nations and rulers are governed more by interests and passions than by reason or philanthropy. When will passions and interests cease to be dominant or disturbing forces? To these most of the wars which history records are to be traced. And yet, whatever may be the origin or character of wars, those who stimulate or engage in them find plausible excuses,--necessity, patriotism, expediency, self-defence, even religion and liberty. So long then as men are blinded by their passions and interests, and palliate or justify their wars by either truth or sophistry, there is but little hope that they will cease, even with the advance of civilization. When has there been a long period unmarked by war? When have wars been more destructive and terrible than within the memory of this generation? It would indeed seem that when nations shall learn that their real interests are not antagonistic, that they cannot afford to go to war with one another, peace would then prevail as a policy not less than as a principle. This is the hopeful view to take; but unfortunately it is not the lesson taught by history, nor by that philosophy which has been generally accepted by Christendom for eighteen hundred years,--which is that men will not be governed by the loftiest principles until the religion of Jesus shall have conquered and changed the heart of the world, or at least of those who rule the world.
