The clergy, who had in so many ways served the cause of freedom during the prolonged strife against feudalism and slavery, were associated now with the interest of royalty. Attempts had been made to reform the Church on the Constitutional model; they had failed, but they had united the hierarchy and the crown against the system of divided power as against a common enemy. Strong kings were able to bring the spirituality under subjection in France and Spain, in Sicily and in England. The absolute monarchy of France was built up in the two following centuries by twelve political cardinals. The kings of Spain obtained the same effect almost at a single stroke by reviving and appropriating to their own use the tribunal of the Inquisition, which had been growing obsolete, but now served to arm them with terrors which effectually made them despotic. One generation beheld the change all over Europe, from the anarchy of the days of the Roses to the passionate submission, the gratified acquiescence in tyranny that marks the reign of Henry VIII. and the kings of his time.

The tide was running fast when the Reformation began at Wittenberg, and it was to be expected that Luther's influence would stem the flood of absolutism. For he was confronted everywhere by the compact alliance of the Church with the State; and great part of his country was governed by hostile potentates who were prelates of the Court of Rome. He had, indeed, more to fear from temporal than from spiritual foes. The leading German bishops wished that the Protestant demands should be conceded; and the Pope himself vainly urged on the Emperor a conciliatory policy. But Charles V. had outlawed Luther, and attempted to waylay him; and the Dukes of Bavaria were active in beheading and burning his disciples, whilst the democracy of the towns generally took his side. But the dread of revolution was the deepest of his political sentiments; and the gloss by which the Guelphic divines had got over the passive obedience of the apostolic age was characteristic of that mediæval method of interpretation which he rejected. He swerved for a moment in his later years; but the substance of his political teaching was eminently conservative, the Lutheran States became the stronghold of rigid immobility, and Lutheran writers constantly condemned the democratic literature that arose in the second age of the Reformation. For the Swiss reformers were bolder than the Germans in mixing up their cause with politics. Zurich and Geneva were Republics, and the spirit of their governments influenced both Zwingli and Calvin.

Zwingli indeed did not shrink from the mediæval doctrine that evil magistrates must be cashiered; but he was killed too early to act either deeply or permanently on the political character of Protestantism. Calvin, although a Republican, judged that the people are unfit to govern themselves, and declared the popular assembly an abuse that ought to be abolished. He desired an aristocracy of the elect, armed with the means of punishing not only crime but vice and error. For he thought that the severity of the mediæval laws was insufficient for the need of the times; and he favoured the most irresistible weapon which the inquisitorial procedure put into the hand of the Government, the right of subjecting prisoners to intolerable torture, not because they were guilty, but because their guilt could not be proved. His teaching, though not calculated to promote popular institutions, was so adverse to the authority of the surrounding monarchs, that he softened down the expression of his political views in the French edition of his Institutes.

The direct political influence of the Reformation effected less than has been supposed. Most States were strong enough to control it. Some, by intense exertion, shut out the pouring flood. Others, with consummate skill, diverted it to their own uses. The Polish Government alone at that time left it to its course. Scotland was the only kingdom in which the Reformation triumphed over the resistance of the State; and Ireland was the only instance where it failed, in spite of Government support. But in almost every other case, both the princes that spread their canvas to the gale and those that faced it, employed the zeal, the alarm, the passions it aroused as instruments for the increase of power. Nations eagerly invested their rulers with every prerogative needed to preserve their faith, and all the care to keep Church and State asunder, and to prevent the confusion of their powers, which had been the work of ages, was renounced in the intensity of the crisis. Atrocious deeds were done, in which religious passion was often the instrument, but policy was the motive.

Fanaticism displays itself in the masses, but the masses were rarely fanaticised, and the crimes ascribed to it were commonly due to the calculations of dispassionate politicians. When the King of France undertook to kill all the Protestants, he was obliged to do it by his own agents. It was nowhere the spontaneous act of the population, and in many towns and in entire provinces the magistrates refused to obey. The motive of the Court was so far from mere fanaticism that the Queen immediately challenged Elizabeth to do the like to the English Catholics. Francis I. and Henry II. sent nearly a hundred Huguenots to the stake, but they were cordial and assiduous promoters of the Protestant religion in Germany. Sir Nicholas Bacon was one of the ministers who suppressed the mass in England. Yet when the Huguenot refugees came over he liked them so little that he reminded Parliament of the summary way in which Henry V. at Agincourt dealt with the Frenchmen who fell into his hands. John Knox thought that every Catholic in Scotland ought to be put to death, and no man ever had disciples of a sterner or more relentless temper. But his counsel was not followed.

All through the religious conflict policy kept the upper hand. When the last of the Reformers died, religion, instead of emancipating the nations, had become an excuse for the criminal art of despots. Calvin preached and Bellarmine lectured, but Machiavelli reigned. Before the close of the century three events occurred which mark the beginning of a momentous change. The massacre of St. Bartholomew convinced the bulk of Calvinists of the lawfulness of rebellion against tyrants, and they became advocates of that doctrine in which the Bishop of Winchester had led the way,[4] and which Knox and Buchanan had received, through their master at Paris, straight from the mediæval schools. Adopted out of aversion to the King of France, it was soon put in practice against the King of Spain. The revolted Netherlands, by a solemn Act, deposed Philip II., and made themselves independent under the Prince of Orange, who had been, and continued to be, styled his Lieutenant. Their example was important, not only because subjects of one religion deposed a monarch of another, for that had been seen in Scotland, but because, moreover, it put a republic in the place of a monarchy, and forced the public law of Europe to recognise the accomplished revolution. At the same time, the French Catholics, rising against Henry III., who was the most contemptible of tyrants, and against his heir, Henry of Navarre, who, as a Protestant, repelled the majority of the nation, fought for the same principles with sword and pen.

Many shelves might be filled with the books which came out in their defence during half a century, and they include the most comprehensive treatises on laws ever written. Nearly all are vitiated by the defect which disfigured political literature in the Middle Ages. That literature, as I have tried to show, is extremely remarkable, and its services in aiding human progress are very great. But from the death of St. Bernard until the appearance of Sir Thomas More's Utopia, there was hardly a writer who did not make his politics subservient to the interest of either Pope or King. And those who came after the Reformation were always thinking of laws as they might affect Catholics or Protestants. Knox thundered against what he called the Monstrous Regiment of Women, because the Queen went to mass, and Mariana praised the assassin of Henry III. because the King was in league with Huguenots. For the belief that it is right to murder tyrants, first taught among Christians, I believe, by John of Salisbury, the most distinguished English writer of the twelfth century, and confirmed by Roger Bacon, the most celebrated Englishman of the thirteenth, had acquired about this time a fatal significance. Nobody sincerely thought of politics as a law for the just and the unjust, or tried to find out a set of principles that should hold good alike under all changes of religion. Hooker's Ecclesiastical Polity stands almost alone among the works I am speaking of, and is still read with admiration by every thoughtful man as the earliest and one of the finest prose classics in our language. But though few of the others have survived, they contributed to hand down masculine notions of limited authority and conditional obedience from the epoch of theory to generations of free men. Even the coarse violence of Buchanan and Boucher was a link in the chain of tradition that connects the Hildebrandine controversy with the Long Parliament, and St. Thomas with Edmund Burke.

That men should understand that governments do not exist by divine right, and that arbitrary government is the violation of divine right, was no doubt the medicine suited to the malady under which Europe languished. But although the knowledge of this truth might become an element of salutary destruction, it could give little aid to progress and reform. Resistance to tyranny implied no faculty of constructing a legal government in its place. Tyburn tree may be a useful thing, but it is better still that the offender should live for repentance and reformation. The principles which discriminate in politics between good and evil, and make States worthy to last, were not yet found.

The French philosopher Charron was one of the men least demoralised by party spirit, and least blinded by zeal for a cause. In a passage almost literally taken from St. Thomas, he describes our subordination under a law of nature, to which all legislation must conform; and he ascertains it not by the light of revealed religion, but by the voice of universal reason, through which God enlightens the consciences of men. Upon this foundation Grotius drew the lines of real political science. In gathering the materials of international law, he had to go beyond national treaties and denominational interests for a principle embracing all mankind. The principles of law must stand, he said, even if we suppose that there is no God. By these inaccurate terms he meant that they must be found independently of revelation. From that time it became possible to make politics a matter of principle and of conscience, so that men and nations differing in all other things could live in peace together, under the sanctions of a common law. Grotius himself used his discovery to little purpose, as he deprived it of immediate effect by admitting that the right to reign may be enjoyed as a freehold, subject to no conditions.

When Cumberland and Pufendorf unfolded the true significance of his doctrine, every settled authority, every triumphant interest recoiled aghast. None were willing to surrender advantages won by force or skill, because they might be in contradiction, not with the Ten Commandments, but with an unknown code, which Grotius himself had not attempted to draw up, and touching which no two philosophers agreed. It was manifest that all persons who had learned that political science is an affair of conscience rather than of might or expediency, must regard their adversaries as men without principle, that the controversy between them would perpetually involve morality, and could not be governed by the plea of good intentions, which softens down the asperities of religious strife. Nearly all the greatest men of the seventeenth century repudiated the innovation. In the eighteenth, the two ideas of Grotius, that there are certain political truths by which every State and every interest must stand or fall, and that society is knit together by a series of real and hypothetical contracts, became, in other hands, the lever that displaced the world. When, by what seemed the operation of an irresistible and constant law, royalty had prevailed over all enemies and all competitors, it became a religion. Its ancient rivals, the baron and the prelate, figured as supporters by its side. Year after year, the assemblies that represented the self-government of provinces and of privileged classes, all over the Continent, met for the last time and passed away, to the satisfaction of the people, who had learned to venerate the throne as the constructor of their unity, the promoter of prosperity and power, the defender of orthodoxy, and the employer of talent.
