With such a people on his borders, and every day becoming more formidable, what was Charlemagne's policy? What was he to do? The only thing to the eye of that enlightened statesman was to conquer them, if possible, and add their territories to the Frankish Empire. If left to themselves, they might have conquered the Franks. It was either anvil or hammer. There could be no lasting peace in Europe while these barbarians were left to pursue their depredations. A vigorous warfare was imperative, for, unless subdued, a disadvantageous war would be carried on near the frontiers, until some warrior would arise among them, unite the various chieftains, and lead his followers to successful invasion. Charlemagne knew that the difficult and unpleasant work of subjugation must be done by somebody, and he was unwilling to leave the work to enervated successors. The work was not child's play. It took him the best part of his life to accomplish it, and amid great discouragements. Of his fifty-three expeditions, eighteen were against the Saxons. As soon as he had cut off one head of the monster, another head appeared. How allegorical of human labor is that old fable of the Hydra! Where do man's labors cease? Charlemagne fought not only amid great difficulties, but perpetual irritations. The Saxons cheated him; they broke their promises and their oaths. When beaten, they sued for peace; but the moment his back was turned, they broke out in new insurrections. The fame of Caesar chiefly rests on his eight campaigns in Gaul. But Caesar had the disciplined Legions of Rome to fight with. Charlemagne had no such disciplined troops. Yet he had as many difficulties to surmount as Caesar,—rugged forests to penetrate, rapid rivers to cross, morasses to avoid, and mountains to climb. It is a very difficult thing to subdue even savages who are desperate, determined, and united.

Charlemagne fought the Saxons for thirty-three years. Though he never lost a battle, they still held out. At first he was generous and forgiving, for he was more magnanimous than Caesar; but they could not be won by kindness. He was obliged to change his course, and at last was as summary as Oliver Cromwell in Ireland. He is even accused of cruelties. But war in the hands of masters has no quarter to give, and no tears to shed. It was necessary to conquer the Saxons, and Charlemagne used the requisite means. Sometimes the harshest measures will most speedily effect the end. Did our fathers ever dream of compromise with treacherous and hostile Indians? War has a horrid maxim,—that "nothing is so successful as success." Charlemagne, at last, was successful. The Saxons were so completely subdued at the end of thirty-three years, that they never molested civilized Europe again. They became civilized, like the once invading Celts and Goths; and they even embraced the religion of the conquerors. They became ultimately the best people in Europe,—earnest, honest, and brave. They formed great kingdoms and states, and became new barriers against fresh inundations from the North and East. The Saxons formed the nucleus of the great German Empire (or were incorporated with it) which arose in the Middle Ages, and which to-day is the most powerful in Europe, and the least corrupted by the vices of a luxurious life. The descendants of those Saxons are among the most industrious and useful settlers in the New World.

There was one mistake which Charlemagne made in reference to them. He forced their conversion to a nominal Christianity. He immersed them in the rivers of Saxony, whether they would or no. He would make them Christians in his way. But then, who does not seek to make converts in his way, whether enlightened or not? When have the principles of religious toleration been understood? Did the Puritans understand them, with all their professions? Do we tolerate, in our hearts, those who differ from us? Do not men look daggers, though they dare not use them? If we had the power, would we not seek to produce conformity with our notions, like Queen Elizabeth, or Oliver Cromwell, or Archbishop Laud? There is not perhaps a village in America where a true catholicism reigns. There is not a spot upon the globe where there is not some form of religious persecution. Nor is there any thing more sincere than religious bigotry. And where people have not fundamental principles to fight about, they will fight about technicalities and matters of no account, and all the more bitterly sometimes when the objects of contention are not worth fighting about at all,—as in forms of worship, or baptism. Such is the weakness of human nature. Charlemagne was no exception to the race. But if he wished to make Christians in his way, he was, on the whole, enlightened. He caused the young Saxons, whom he baptized and marked with the sign of the Cross, to be educated. He built monasteries and churches in the conquered territories. He recognized this,—that Christianity, whatever it be, is the mightiest power of the world; and he bore his testimony in behalf of the intellectual dignity of the clergy in comparison with other classes. He encouraged missions as well as schools.

There was another Germanic tribe at that time which he held in great alarm, but which he did not attack, since they were not immediately dangerous. This tribe or race was the Norman, just then beginning their ravages,—pirates in open boats. They had dared to enter a port in Narbonensis Gaul for purposes of plunder. Some took them for Africans, and others for British merchants. Nay, said Charlemagne, they are not merchants, but cruel enemies; and he covered his face with his iron hands and wept like a child. He did not fear these barbarians, but he wept when he foresaw the evil they would do when he was dead. "I weep," said he, "that they should dare almost to land on my shores, in my lifetime." These Normans escaped him. They conquered and they founded kingdoms. But they did not replunge Europe in darkness. A barrier had been made against their inundation. The Saxon conquest was that barrier. Moreover, the Normans were the noblest race of barbarians which then roamed through the forests of Germany, or skirted the shores of Scandinavia. They had grand natural traits of character. They were poetic, brave, and adventurous. They were superior to the Saxons and the Franks. When converted, they were the great allies of the Pope, and early became civilized. To them we trace the noblest development of Gothic architecture. They became great scholars and statesmen. They were more refined by nature than the Saxons, and avoided their gluttonous habits. In after times they composed the flower of European chivalry. It was providential that they were not subdued,—that they became the leading race in Northern Europe. To them we trace the mercantile greatness of England, for they were born sailors. They never lost their natural heroism, or love of power.

The next important conquest of Charlemagne was that of the Avares,– a tribe of the Huns, of Slavonic origin. They are represented as very hideous barbarians, and only thought of plunder. They never sought to reconstruct. There seemed to be no end of their invasions from the time of Attila. They were more formidable for their numbers and destructive ravages than for their military skill. There was a time, however, when they threatened the combined forces of Germany and Rome; but Europe was delivered by the battle of Poictiers,—the bloodiest battle on record,—when they seemed to be annihilated. But they sprang up again, in new invasions, in the ninth century. Had they conquered, civilization would have been crushed out. But Charlemagne was successful against them, and from that time to this they were shut out from western Europe. They would be formidable now, for the Russians are the descendants of these people, were it not for the barrier raised against them by the Germans. The necessities of Europe still require the vast military strength and organization of Germany, not to fight France, but to awe Russia. Napoleon predicted that Europe would become either French or Cossack; but there is little probability of Russian aggressions in Europe, so long as Russia is held in check by Germany.

Charlemagne had now delivered France and Germany from external enemies. He then turned his arms against the Saracens of Spain. This was the great mistake of his life. Yet every one makes mistakes, however great his genius. Alexander made the mistake of pushing his arms into India; and Napoleon made a great blunder in invading Russia. Even Caesar died at the right time for his military fame, for he was on the point of attempting the conquest of Parthia, where, like Crassus, he would probably have perished, or have lost his army. Needless conquests seem to be impossible in the moral government of God, who rules the fate of war. Conquests are only possible when civilization seems to require them. In seeking to invade Spain, Charlemagne warred against a race from whom Europe had nothing more to fear. His grandfather, Charles Martel, had arrested the conquests of the Saracens; and they were quiet in their settlements in Spain, and had made considerable attainments in science and literature. Their schools of medicine and their arts were in advance of the rest of Europe. They were the translators of Aristotle, who reigned in the rising universities during the Middle Ages. As this war was unnecessary, Providence seemed to rebuke Charlemagne. His defeat at Roncesvalles was one of the most memorable events in his military history. Prodigies of valor were wrought by him and his gallant Paladins. The early heroic poetry of the Middle Ages has commemorated his exploits, as well as those of his nephew Roland, to whom some writers have ascribed the origin of Chivalry. But the Frankish forces were signally defeated amid the passes of the Pyrenees; and it was not until after several centuries that the Gothic princes of Spain shook off the yoke of their Saracenic conquerors, and drove them from Europe.

The Lombard wars of Charlemagne are the last to which I allude. These were undertaken in defence of the Church, to rescue his ally the Pope. The Lombards belonged to the great Germanic family, but they were unfriendly to the Pope and to the Church. They stood out against the Empire, which was then the chief hope of Europe and of civilization. They would have reduced the Pope to insignificance and seized his territories, without uniting Italy. So Charlemagne, like his father Pepin, lent his powerful aid to the Roman bishop, and the Lombards were easily subdued. This conquest, although the easiest which he ever made, most flattered his pride. Lombardy was not only joined to his Empire, but he received unparalleled honors from the Pope, being crowned by him Emperor of the West.

It was a proud day when, in the ancient metropolis of the world, and in the fulness of his fame, Pope Leo III. placed the crown of Augustus upon Charlemagne's brow, and gave to him, amid the festivities of Christmas, his apostolic benediction. His dominions now extended from Catalonia to the Bohemian forests, embracing Germany, France, the Netherlands, Italy, and the Spanish main,—the largest empire which any one man has possessed since the fall of the Roman Empire. What more natural than for Charlemagne to feel that he had restored the Western Empire? What more natural than that he should have taken the title, still claimed by the Austrian emperor, in one sense his legitimate successor,—Kaiser, or Caesar? In the possession of such enormous power, he naturally dreamed of establishing a new universal military monarchy like that of the Romans,—as Charles V. dreamed, and Napoleon after him. But this is a dream that Providence has rebuked among all successive conquerors. There may have been need of the universal monarchy of the Caesars, that Christianity might spread in peace, and be protected by a reign of law and order. This at least is one of the platitudes of historians. Froude himself harps on it in his life of Caesar. Historians are fond of exalting the glories of imperialism, and everybody is dazzled by the splendor and power of ancient Roman emperors. They do not, I think, sufficiently consider the blasting influence of imperialism on the life of nations, how it dries up the sources of renovation, how it necessarily withers literature and philosophy, how nothing can thrive under it but pomp and material glories, how it paralyzes all virtuous impulses, how it kills all enthusiasm, how it crushes out all hope and lofty aspirations, how it makes slaves of its best subjects, how it fills the earth with fear, how it drains national resources to support standing armies, how it mocks all enterprises which do not receive imperial approbation, how everything is concentrated to reflect the glory of one man or family; how impossible, under its withering shade, is manly independence, or the free expression of opinions or healthy growth; how it buries up, under its armies, discontents and aspirations alike, and creates nothing but machinery which must ultimately wear out and leave a world in ruins, with nothing stable to take its place. Law and order are good things, the preservation of property is desirable, the punishment of crime is necessary; but there are other things which are valuable also. Nothing is so valuable as the preservation of national life; nothing is so healthy as scope for energies; nothing is so contemptible and degrading as universal sycophancy to official rule. There are no tyrants more oppressive than the tools of absolute power. See in what a state imperialism left the Roman Empire when it fell. There were no rallying forces; there was no resurrection of heroes. Vitality had fled. Where would Turkey be to-day without the European powers, if the Sultan's authority were to fall? It would be in the state of ancient Babylon or Persia when those empires fell.

There is another side to imperialism besides dreaded anarchies. Moreover, the whole progress of civilization has been counter to it. The fiats of eternal justice have pronounced against it, because it is antagonistic to the dignity of man and the triumphs of reason. I would not fall in with the cant of the dignity of man, because there is no dignity to man without aid from God Almighty through His spirit and the message he has sent in Christianity. But there is dignity in man with the aid of a regenerating gospel. Some people talk of the triumphs of Christianity under the Roman emperors; but see how rapidly it was corrupted by them when they sought the aid of its institutions to bolster up their power. The power of Christianity is in its truths; in its religion, and not in its forms and institutions, in its inventions to uphold the arms of despotism and the tools of despotism. It is, and it was, and it will be through all the ages the great power of the world, against which it is vain to rebel. And that government is really the best which unfetters its spiritual influence, and encourages it; and not that government which seeks to perpetuate its corrupt and worldly institutions. The Roman emperors made Christianity an institution, and obscured its truths. And perhaps that is one reason why Providence permitted their despotism to pass away,—preferring the rude anarchy of the Germanic nations to the dead mechanism of a lifeless Church and imperial rottenness. Imperialism must ever end in rottenness. And that is one reason why the heart of Christendom—I mean the people of Europe, in its enlightened and virtuous sections has ever opposed imperialism. The progress has been slow, but marked, towards representative governments,—not the reign of the people directly, but of those whom they select to represent them. The victory has been nearly gained in England. In France the progress has been uniform since the Revolution. Napoleon revived, or sought to revive, the imperialism of Rome. He failed. There is nothing which the French now so cordially detest, since their eyes have been opened to the character and ends of that usurper, as his imperialism. It cannot be revived any more easily than the oracles of Dodona. Even in Germany there are dreadful discontents in view of the imperialism which Bismarck, by the force of successful wars, has seemingly revived. The awful standing armies are a menace to all liberty and progress and national development. In Italy itself there is the commencement of constitutional authority, although it is united under a king. The great standing warfare of modern times is constitutional authority against the absolute power of kings and emperors. And the progress has been on the side of liberty everywhere, with occasional drawbacks, such as when Louis Napoleon revived the accursed despotism of his uncle, and by the same means,—a standing army and promises of military glory.
