Saint-Louis was but a boy of eleven when he succeeded to the throne on the death of his father, and a coalition of the great nobles was immediately formed to take advantage of his minority; but the wisdom, prudence, and piety of his mother, Blanche of Castile, not only preserved the crown for him until he came of age, but also stood him in great service during the years of his reign, especially in those in which he was absent from the kingdom on his ill-starred crusades. One of her most beneficent deeds has been immortalized by the modern painter, Luc-Olivier-Merson, in a noble mural painting,—the delivery of the prisoners held in bondage by the chapitre de Paris (Notre-Dame), several inhabitants of Châtenay who had incurred the displeasure of the ecclesiastical authorities, and who were so maltreated in their dungeons that the lives of several of them were despaired of. The queen at first sent a civil request to the chapter to release the captives under bonds, but the churchmen returned an uncivil refusal and redoubled their severities; whereupon she proceeded in person to the prison with her son, struck the doors with her bâton, her guards immediately broke them down, and the liberated serfs, men, women, and children, flocked out tumultuously to thank their deliverers on their knees. The canons protested furiously, but the discreet regent, knowing their sensitive point, allowed them to rage openly and contented herself with seizing their temporal revenues. This immediately brought them to terms; in the smoothest of phrases they besought an accommodation, and speedily agreed to set at liberty, in consideration of a certain sum, all those whom they had unjustly incarcerated.

It would scarcely have been thought that this gracious sovereign lady, one of the noblest figures among the women of France, could have been made the object of malicious slander; but one of her latest biographers, M. Élie Berger, thinks it worth while to defend her seriously against the "legend born of jealousy and impotence" of having been the mistress of the Cardinal de Saint-Ange and of the Comte Thibaut de Champagne. His defence, apart from the inherent improbability of the story, seems to be quite convincing.

The centre of authority, for both the nation and the capital, was naturally the king, though, as we have seen, his power was often furiously contested and at times very precarious. Under the Mérovingians, the crown was both elective and hereditary, that is to say, the brother of the deceased monarch was frequently chosen in the place of his eldest son, too young to bear worthily the sword and the sceptre. The royal authority was practically unlimited, the king decreed constitution and laws, made war, and signed treaties of peace; he wore the Roman costume, spoke and wrote in Latin, sate, like the Emperor, in the prætorium to judge, and was given the titles of Dominus, of Excellency, and of Majesty. For the personal service of the king, and for the public service, there were a great number of officers,—the major domus or mayor of the palace, who eventually pushed the monarch off the throne and mounted it himself; the marshal, the treasurer, the cup-bearer, the chamberlain, and a multitude of inferior officers. The political officers were more particularly the Comte du Palais, who sate in the king's tribunal, and the Réferéndaire, a sort of chancellor, who kept the royal signet-ring and sealed the royal decrees. The court, or palatium, was crowded with important personages, counts, dukes, and bishops, any of whom might be called to the king's council or to sit in his tribunal. In the provinces, the royal authority was represented in the comtés, which corresponded to the civitates of the Romans, by the comtes, who were at once judges, generals, and financial administrators, and the ducs whose administrative province included several comtés. The bishops already enjoyed very considerable political power, and the rôle of the king in their election, by the people and the clerks of their diocese, was confined to confirmation,—a limitation which they very frequently disregarded.

In the edict, or perpetual constitution, drawn up by the assembly of seventy-nine bishops and the leudes or great vassals of the three kingdoms, held at Paris in 615, the interference of the king in the election of the bishops was expressly forbidden, and his authority was in many other matters seriously impaired in favor of the double aristocracy, ecclesiastical and military, which was strengthening itself. With the unworthy sons of the "good king Dagobert" this authority gradually disappeared entirely under the rising power of the mayors of the palace, who succeeded in making their office hereditary under an Austrasian family, that of the Carlovingians, already powerful in their own right.

Charlemagne's court was constituted much in the same manner as that of the Mérovingians: his royal officers included bishops, comtes, ducs, missi dominici, any of whom were eligible for the council that could at need be transformed into a tribunal to judge the causes of the Francs. The efforts of this monarch to repress the persistent progress of the aristocracy were more intelligent and successful than those of his successors, but the general movement of society was in their favor. Charles le Chauve, desirous of obtaining the imperial crown, which was without an owner in 875, assembled his vassals at a diet at Kiersy-sur-Oise and there signed a capitulaire which gave to the sons of those of his comtes who followed him into Italy the right to succeed to their fathers' titles. This formal recognition of a practice already ancient deprived the king of the powers which he had once conferred.

The Capétiens were also elected to the throne, but the Roman tradition, preserved by the Church, recognized in their accession to power "a decree of Providence," and the sovereign was recognized in the feudal suzerain, "even when he was not obeyed." The great royal officers, the Ministerium regale, included the Chancelier, who signed the state papers; the Sénéchal, a species of mayor of the palace, of which he had charge of the service; the Connétable, chief of the royal stables and, later, head of the military forces; the Chambrier, keeper of the treasury and the archives; the Bouteillier, who administered the vineyards and the revenues of the royal domains. All these high offices were made the objects of persistent attempts on the part of the holders to retain them as hereditary privileges. In the eleventh, as in the sixth century, we find three classes of society in Gaul, the Gallo-Romans,—the barbarians,—the clercs,—the Church being replaced by the seigneurs,—and the serfs, each with its own organization and manners and customs and, in a certain degree, its peculiar language and literature. The first two were rich, active, and powerful; the last, poor and oppressed. There were three species of jurisdiction exercised by the seigneurs, high, medium, and lower, though some of them had the right only to the last two; these distinctions were frequently regulated by the quality of the accused, and were definitely determined only in succeeding centuries. The right to administer high justice carried with it that of executing death-sentences, and the pillory and the gibbet, erected near the château, were the visible evidences of this power. The bishops and the abbots had the same rights as the seigneurs, even to the extent of donning armor and combating in person if they so willed.

The obligations of the vilains, or serfs, included a long list of services, taxes, and obligations of all kinds; in the cities, and wherever possible, the seigneurs were in the habit of requiring payment in money. There was for them a civil as well as a penal law, the loi vilaine. They had, however, the right of appeal to the suzerain against the decision of their seigneurs, and Saint-Louis favored these appeals to his own court as tending to subordinate the seigneurial justice to his own. In this royal court a change was taking place,—to the great officers of the crown were now added légistes, as the procedures were based upon written precedent, and these bookish personages, at first treated with contempt by the nobles, gradually assumed the leading rôle as their familiarity with the records and their legal knowledge triumphed over the ignorant assurance of their betters.

In the thirteenth century, "the great revolutionist is the king, as the aristocracy had been before Hugues Capet, as the people will be after Louis XIV.... The royal authority had overthrown a great many barriers, and it was marching with great strides toward absolute power. It had imposed upon its turbulent vassals the king's peace, the king's justice, the king's coinage, and it enacted laws for all." In the character of Saint-Louis, "the spirit of justice which is in the Roman law was well combined with his Christian sentiments. When he condemned, for example, the judicial duel, he did so because combat is not a means of justice,—this is the Roman conception, and because it is to criminally tempt God,—this is the Christian spirit." The enfranchisement of the serfs, which received so great an impulse in this century, was largely brought about by a somewhat similar combination of just impulses and of practical motives,—the latter being frankly expressed by Beaumanoir and in several charters of the period.

The feudal court of the king had the double character of a council and of a court of justice; with the growth of the royal authority the functions of this court naturally increased, and it became necessary to divide them,—there was accordingly constituted the political court, or grand council, and the judicial court, or Parlement. Philippe le Bel, who was far more of an innovator than even Saint-Louis, first gave the latter a distinct organization. It was to sit twice a year at Paris, two months at a time, in the Palais de la Cité, which, in 1303, took the name of the Palais de Justice. The monarch counted upon his sovereign court of justice, which extended its jurisdiction over the whole kingdom, to bring the nation definitely under the royal authority. As the Parlement had been separated from the Grand Conseil, or royal court, so was there separated from it the Chambre des Comptes, charged with the administration of the finances. With this monarch also originated the institution of the ministère public, or magistrates charged, in all legal cases, with the defence of the rights of the king and of the public welfare.
