It is thus that we shall ever find, in the labours of man, one half fruitless, by the side of another moiety profitable; we shall then no longer condemn the curiosity which leads to knowledge; we shall acknowledge that, if the human mind often wanders in its path, if it has not always selected the most direct road, it has finally arrived, by the necessity of its nature, at the discovery of important truths; but, with progressive enlightenment, we shall endeavour not to lose time, to go straight to the end by concentrating our strength on fruitful inquiries and profitable results; and we shall soon convince ourselves that what man cannot do is valueless, and that he can achieve all that is necessary.

The application of this idea to history will soon remove the difficulty which its uncertainty raised at the outset. For example, it is of little consequence to us to know the exact personal appearance or the precise day of the birth of Constantine; to ascertain what particular motives or individual feelings may have influenced his determination or conduct on any given occasion; to be acquainted with all the details of his wars and victories in the struggles with Maxentius or Licinius: these minor points concern the monarch alone; and the monarch exists no longer. The anxiety some scholars display in hunting them out is merely a consequence of the interest which attaches to great names and important reminiscences. But the results of the conversion of Constantine, his administrative system, the political and religious principles which he established in his empire,—these are the matters which it imports the present generation to investigate; for they do not expire with a particular age, they form the destiny and glory of nations, they confer or take away the use of the most noble faculties of man; they either plunge them silently into a state of misery alternately submissive and rebellious, or establish for them the foundation of a lasting happiness.

It may be said, to a certain extent, that there are two pasts, the one entirely extinct and without real interest, because its influence has not extended beyond its actual duration; the other enduring for ever by the empire it has exercised over succeeding ages, and by that alone preserved to our knowledge, since what remains of it is there to enlighten us upon what has perished. History presents us, at every epoch, with some predominant ideas, some great events which have decided the fortune and character of a long series of generations. These ideas and events have left monuments which still remain, or which long remained, on the face of the world; an extended trace, in perpetuating the memory and effect of their existence, has multiplied the materials suitable for our guidance in the researches of which they are the object; reason itself can here supply us with its positive data to conduct us through the uncertain labyrinth of facts. In a past event there may have been some particular circumstance at present unknown, which would completely alter the idea we have formed of it. Thus, we shall never discover the reason which delayed Hannibal at Capua, and saved Rome; but in an effect which has endured for a long time, we easily ascertain the nature of its cause. The despotic authority which the Roman Senate exercised for ages over the people, explains to us the ideas of liberty within which the Senators restricted themselves when they expelled their kings. Let us then follow the path in which we can have reason for our guide; let us apply the principles, with which she furnishes us, to the examples borrowed from history. Man, in the ignorance and weakness to which the narrow limits of his life and faculties condemn him, has received reason to supply knowledge, as industry is given to him in place of strength.

Such, gentlemen, is the point of view under which we shall endeavour to contemplate history. We shall seek, in the annals of nations, a knowledge of the human race; we shall try to discover what, in every age and state of civilization, have been the prevailing ideas and principles in general adoption, which have produced the happiness or misery of the generations subjected to their power, and have influenced the destiny of those which succeeded them. The subject is one of the most abundant in considerations of this nature. History presents to us periods of development, during which man, emerging from a state of barbarism and ignorance, arrives gradually at a condition of science and advancement, which may decline, but can never perish, for knowledge is an inheritance that always finds heirs. The civilization of the Egyptians and Phœnicians prepared that of the Greeks; while that of the Romans was not lost to the barbarians who established themselves upon the ruins of the Empire. No preceding age has ever enjoyed the advantage we possess, of studying this slow but real progression: while looking back on the past, we can recognize the route which the human race has followed in Europe for more than two thousand years. Modern history alone, from its vast scope, from the variety and extent of its duration, offers us the grandest and most complete picture which we could possibly possess of the civilization of a certain portion of the globe. A rapid glance will suffice to indicate the character and interest of the subject.

Rome had conquered what her pride delighted to call the world. Western Asia, from the frontiers of Persia, the North of Africa, Greece, Macedonia, Thrace, all the countries situated on the right bank of the Danube, from its source to its mouth, Italy, Gaul, Great Britain, and Spain, acknowledged her authority. That authority extended over more than a thousand leagues in breadth, from the Wall of Antoninus and the southern boundaries of Dacia, to Mount Atlas;—and beyond fifteen hundred leagues in length, from the Euphrates to the Western Ocean. But if the immense extent of these conquests at first surprises the imagination, the astonishment diminishes when we consider how easy they were of accomplishment, and how uncertain of duration. In Asia, Rome had only to contend with effeminate races; in Europe, with ignorant savages, whose governments, without union, regularity, or vigour, were unable to contend with the strong constitution of the Roman aristocracy. Let us pause a moment to reflect on this. Rome found it more difficult to defend herself against Hannibal than to subjugate the world; and as soon as the world was subdued, Rome began to lose, by degrees, all that she had won by conquest. How could she maintain her power? The comparative state of civilization between the victors and the vanquished had prevented union or consolidation into one substantial and homogeneous whole; there was no extended and regular administration, no general and safe communication; the provinces were only connected with Rome by the tribute they paid; Rome was unknown in the provinces, except by the tribute she exacted. Everywhere, in Asia Minor, in Africa, in Spain, in Britain, in the North of Gallia, small colonies defended and maintained their independence; all the power of the Emperors was inadequate to compel the submission of the Isaurians. The whole formed a chaos of nations half vanquished and semi-barbarous, without interest or existence in the State of which they were considered a portion, and which Rome denominated the Empire.

No sooner was this Empire conquered, than it began to dissolve, and that haughty city which looked upon every region as subdued where she could, by maintaining an army, appoint a proconsul, and levy imposts, soon saw herself compelled to abandon, almost voluntarily, the possessions she was unable to retain. In the year of Christ 270, Aurelian retired from Dacia, and tacitly abandoned that territory to the Goths; in 412, Honorius recognized the independence of Great Britain and Armorica; in 428, he wished the inhabitants of Gallia Narbonensis to govern themselves. On all sides we see the Romans abandoning, without being driven out, countries whose obedience, according to the expression of Montesquieu, weighed upon them, and which, never having been incorporated with the Empire, were sure to separate from it on the first shock.

The shock came from a quarter which the Romans, notwithstanding their pride, had never considered one of their provinces. Even more barbarous than the Gauls, the Britons, and the Spaniards, the Germans had never been conquered, because their innumerable tribes, without fixed residences or country, ever ready to advance or retreat, sometimes threw themselves, with their wives and flocks, upon the possessions of Rome, and at others retired before her armies, leaving nothing for conquest but a country without inhabitants, which they re-occupied as soon as the weakness or distance of the conquerors afforded them the opportunity. It is to this wandering life of a hunting nation, to this facility of flight and return, rather than to superior bravery, that the Germans were indebted for the preservation of their independence. The Gauls and Spaniards had also defended themselves courageously; but the one, surrounded by the ocean, knew not where to fly from enemies they could not expel; and the other, in a state of more advanced civilization, attacked by the Romans, to whom the Narbonnese province afforded, in the very heart of Gaul itself, an impregnable base, and repulsed by the Germans from the land into which they might have escaped, were also compelled to submit. Drusus and Germanicus had long before penetrated into Germany; they withdrew, because the Germans always retreating before them, they would, by remaining, have only occupied territory without subjects.

When, from causes not connected with the Roman Empire, the Tartar tribes who wandered through the deserts of Sarmatia and Scythia, from the northern frontiers of China, marched upon Germany, the Germans, pressed by these new invaders, threw themselves upon the Roman provinces, to conquer possessions where they might establish themselves in perpetuity. Rome then fought in defence; the struggle was protracted; the skill and courage of some of the Emperors for a long time opposed a powerful barrier; but the Barbarians were the ultimate conquerors, because it was imperative on them to win the victory, and their swarms of warriors were inexhaustible. The Visigoths, the Alani, and the Suevi established themselves in the South, of Gaul and Spain; the Vandals passed over into Africa; the Huns occupied the banks of the Danube; the Ostrogoths founded their kingdom in Italy; the Franks in the North of Gaul; Rome ceased to call herself the mistress of Europe; Constantinople does not apply to our present subject.

Those nations of the East and the North who transported themselves in a mass into the countries where they were destined to found States, the more durable because they conquered not to extend but to establish themselves, were barbarians, such as the Romans themselves had long remained. Force was their law, savage independence their delight; they were free because none of them had ever thought or believed that men as strong as themselves would submit to their domination; they were brave because courage with them was a necessity; they loved war because war brings occupation without labour; they desired lands because these new possessions supplied them with a thousand novel sources of enjoyment, which they could indulge in while giving themselves up to idleness. They had chiefs because men leagued together always have leaders, and because the bravest, ever held in high consideration, soon become the most powerful, and bequeath to their descendants a portion of their own personal influence. These chiefs became kings; the old subjects of Rome, who at first had only been called upon to receive, to lodge, and feed their new masters, were soon compelled to surrender to them a portion of their estates; and as the labourer, as well as the plant, attaches himself to the soil that nourishes him, the lands and the labourers became the property of these turbulent and lazy owners. Thus feudalism was established,—not suddenly, not by an express convention between the chief and his followers, not by an immediate and regular division of the conquered country amongst the conquerors, but by degrees, after long years of uncertainty, by the simple force of circumstances, as must always happen when conquest is followed by transplantation and continued possession.

We should be wrong in supposing that the barbarians were destitute of all moral convictions. Man, in that early epoch of civilization, does not reflect upon what we call duties; but he knows and respects, amongst his fellow-beings, certain rights, some traces of which are discoverable even under the empire of the most absolute force. A simple code of justice, often violated, and cruelly avenged, regulates the simple intercourse of associated savages. The Germans, unacquainted with any other laws or ties, found themselves suddenly transported into the midst of an order of things founded on different ideas, and demanding different restrictions. This gave them no trouble; their passage was too rapid to enable them to ascertain and supply what was deficient in their legislature and policy. Bestowing little thought on their new subjects, they continued to follow the same principles and customs which recently, in the forests of Germany, had regulated their conduct and decided their quarrels. Thus the conquered people were, at first, more forgotten than vanquished, more despised than oppressed; they constituted the mass of the nation, and this mass found itself controlled without being reduced to servitude, because they were not thought of, and because the conquerors never suspected that they could possess rights which they feared to defend. From thence sprang, in the sequel, that long disorder at the commencement of the Middle Ages, during which everything was isolated, fortuitous, and partial; hence also proceeded the absolute separation between the nobles and the people, and those abuses of the feudal system which only became portions of a system when long possession had caused to be looked upon as a right, what at first was only the produce of conquest and chance.
