The eighth war, the "War of the Three Henries," that is, of Henri III. and Henri de Guise against Henri of Navarre, now broke out. The Pope made his voice heard; Sixtus excommunicated the Bourbons, Henri and Conde, and blessed the Leaguers.
For the first time there was some real life in one of these civil ware, for Henri of Navarre rose nobly to the level of his troubles. At first the balance of successes was somewhat in favour of the Leaguers; the political atmosphere grew even more threatening, and terrible things, like lightning flashes, gleamed out now and again. Such, for example, was the execution of Mary Stuart, Queen of Scots, in 1586. It was known that Philip II. was preparing to crush England. Elizabeth did what she could to support Henri of Navarre; he had the good fortune to win the battle of Contras, in which the Duc de Joyeuse, one of the favourites of Henri III., was defeated and killed. The Duc de Guise, on the other hand, was too strong for the Germans, who had marched into France to join the Huguenots, and defeated them at Vimroy and Auneau, after which he marched in triumph to Paris, in spite of the orders and opposition of. the King, who, finding himself powerless, withdrew to Chartres. Once more Henri III. was obliged to accept such terms as the Leaguers chose to impose; and with rage in his heart he signed the "Edict of Union" (1588), in which he named the Duc de Guise lieutenant-general of the kingdom, and declared that no heretic could succeed to the throne. Unable to endure the humiliation, Henri III. that same winter, assassinated the Duc and the Cardinal de Guise, and seized many leaders of the League, though he missed the Duc de Mayenne. This scandalous murder of the "King of Paris," as the capital fondly called the Duke, brought the wretched King no solace or power. His mother did not live to see the end of her son; she died in this the darkest period of his career, and must have been aware that her cunning and her immoral life had brought nothing but misery to herself and all her race. The power of the League party seemed as great as ever; the Duc de Mayenne entered Paris, and declared open war on Henri III., who, after some hesitation, threw himself into the hands of his cousin Henri of Navarre in the spring of 1589. The old Politique party now rallied to the King; the Huguenots were stanch for their old leader; things looked less dark for them since the destruction of the Spanish Armada in the previous summer. The Swiss, aroused by the threats of the Duke of Savoy at Geneva, joined the Germans, who once more entered northeastern France; the leaguers were unable to make head either against them or against the armies of the two Kings; they fell back on Paris, and the allies hemmed them in. The defence of the capital was but languid; the populace missed their idol, the Duc de Guise, and the moderate party, never extinguished, recovered strength. All looked as if the royalists would soon reduce the last stronghold of the League, when Henri III. was suddenly slain by the dagger of a fanatical half-wined priest.
The King had only time to commend Henri of Navarre to his courtiers as his heir, and to exhort him to become a Catholic, before he closed his eyes, and ended the long roll of his vices and crimes. And thus in crime and shame the House of Valois went down. For a few years, the throne remained practically vacant: the heroism of Henri of Navarre, the loss of strength in the Catholic powers, the want of a vigorous head to the League,—these things all sustained the Bourbon in his arduous struggle; the middle party grew in strength daily, and when once Henri had allowed himself to be converted, he became the national sovereign, the national favourite, and the high Catholics fell to the fatal position of an unpatriotic faction depending on the arm of the foreigner.
4. The civil wars were not over, for the heat of party raged as yet unslaked; the Politiques could not all at once adopt a Huguenot King, the League party had pledged itself to resist the heretic, and Henri at first had little more than the Huguenots at his back. There were also formidable claimants for the throne. Charles II. Duc de Lorraine, who had married Claude, younger daughter of Henri IL, and who was therefore brother-in-law to Henri III., set up a vague claim; the King of Spain, Philip II., thought that the Salic law had prevailed long enough in France, and that his own wife, the elder daughter of Henri III. had the best claim to the throne; the Guises, though their head was gone, still hoping for the crown, proclaimed their sham-king, the Cardinal de Bourbon, as Charles X., and intrigued behind the shadow of his name. The Duc de Mayenne, their present chief, was the most formidable of Henri's opponents; his party called for a convocation of States General, which should choose a King to succeed, or to replace, their feeble Charles X. During this struggle the high Catholic party, inspired by Jesuit advice, stood forward as the admirers of constitutional principles; they called on the nation to decide the question as to the succession; their Jesuit friends wrote books on the sovereignty of the people. They summoned up troops from every side; the Duc de Lorraine sent his son to resist Henri and support his own claim; the King of Spain sent a body of men; the League princes brought what force they could. Henri of Navarre at the same moment found himself weakened by the silent withdrawal from his camp of the army of Henri III.; the Politique nobles did not care at first to throw in their lot with the Huguenot chieftain; they offered to confer on Henri the post of commander-in-chief, and to reserve the question as to the succession; they let him know that they recognised his hereditary rights, and were hindered only by his heretical opinions; if he would but be converted they were his. Henri temporised; his true strength, for the time, lay in his Huguenot followers, rugged and faithful fighting men, whose belief was the motive power of their allegiance and of their courage. If he joined the Politiques at their price, the price of declaring himself Catholic, the Huguenots would be offended if not alienated. So he neither absolutely refused nor said yes; and the chief Catholic nobles in the main stood aloof, watching the struggle between Huguenot and Leaguer, as it worked out its course.
Henri, thus weakened, abandoned the siege of Paris, and fell back; with the bulk of his forces he marched into Normandy, so as to be within reach of English succour; a considerable army went into Champagne, to be ready to join any Swiss or German help that might come. These were the great days in the life of Henri of Navarre. Henri showed himself a hero, who strove for a great cause—the cause of European freedom—as well as for his own crown.
The Duc de Mayenne followed the Huguenots down into the west, and found Henri awaiting him in a strong position at Arques, near Dieppe; here at bay, the "Bearnais" inflicted a heavy blow on his assailants; Mayenne fell back into Picardy; the Prince of Lorraine drew off altogether; and Henri marched triumphantly back to Paris, ravaged the suburbs and then withdrew to Tours, where he was recognised as King by the Parliament. His campaign of 1589 had been most successful; he had defeated the League in a great battle, thanks to his skilful use of his position at Arques, and the gallantry of his troops, which more than counterbalanced the great disparity in numbers. He had seen dissension break out among his enemies; even the Pope, Sixtus, had shown him some favour, and the Politique nobles were certainly not going against him. Early in 1590 Henri had secured Anjou, Maine, and Normandy, and in March defeated Mayenne, in a great pitched battle at Ivry, not far from Dreux. The Leaguers fell back in consternation to Paris. Henri reduced all the country round the capital, and sat down before it for a stubborn siege. The Duke of Parma had at that time his hands full in the Low Countries; young Prince Maurice was beginning to show his great abilities as a soldier, and had got possession of Breda; all, however, had to be suspended by the Spaniards on that side, rather than let Henri of Navarre take Paris. Parma with great skill relieved the capital without striking a blow, and the campaign of 1590 ended in a failure for Henri. The success of Parma, however, made Frenchmen feel that Henri's was the national cause, and that the League flourished only by interference of the foreigner. Were the King of Navarre but a Catholic, he should be a King of France of whom they might all be proud. This feeling was strengthened by the death of the old Cardinal de Bourbon, which reopened at once the succession question, and compelled Philip of Spain to show his hand. He now claimed the throne for his daughter Elisabeth, as eldest daughter of the eldest daughter of Henri II. All the neighbours of France claimed something; Frenchmen felt that it was either Henri IV. or dismemberment. The "Bearnais" grew in men's minds to be the champion of the Salic law, of the hereditary principle of royalty against feudal weakness, of unity against dismemberment, of the nation against the foreigner.
The middle party, the Politiques of Europe,—the English, that is, and the Germans,—sent help to Henri, by means of which he was able to hold his own in the northwest and southwest throughout 1591. Late in the year the violence of the Sixteen of Paris drew on them severe punishment from the Duc de Mayenne; and consequently the Duke ceased to be the recognised head of the League, which now looked entirely to Philip II. and Parma, while Paris ceased to be its headquarters; and more moderate counsels having taken the place of its fierce fanaticism, the capital came under the authority of the lawyers and citizens, instead of the priesthood and the bloodthirsty mob. Henri, meanwhile, who was closely beleaguering Rouen, was again outgeneralled by Parma, and had to raise the siege. Parma, following him westward, was wounded at Caudebec; and though he carried his army triumphantly back to the Netherlands, his career was ended by this trifling wound. He did no more, and died in 1592.
In 1593, Mayenne, having sold his own claims to Philip of Spain, the opposition to Henri looked more solid and dangerous than ever; he therefore thought the time was come for the great step which should rally to him all the moderate Catholics. After a decent period of negotiation and conferences, he declared himself convinced, and heard mass at St. Denis. The conversion had immediate effect; it took the heart out of the opposition; city after city came in; the longing for peace was strong in every breast, and the conversion seemed to remove the last obstacle. The Huguenots, little as they liked it, could not oppose the step, and hoped to profit by their champion's improved position. Their ablest man, Sully, had even advised Henri to make the plunge. In 1594, Paris opened her gates to Henri, who had been solemnly crowned, just before, at Chartres. He was welcomed with immense enthusiasm, and from that day onwards has ever been the favourite hero of the capital. By 1595 only one foe remained,—the Spanish Court. The League was now completely broken up; the Parliament of Paris gladly aided the King to expel the Jesuits from France. In November, 1595, Henri declared war against Spain, for anything was better than the existing state of things, in which Philip's hand secretly supported all opposition: The war in 1596 was far from being successful for Henri; he was comforted, however, by receiving at last the papal absolution, which swept away the last scruples of France.
By rewards and kindliness,—for Henri was always willing to give and had a pleasant word for all, most of the reluctant nobles, headed by the Duc de Mayenne himself, came in in the course of 1596. Still the war pressed very heavily, and early in 1597 the capture of Amiens by the Spaniards alarmed Paris, and roused the King to fresh energies. With help of Sully (who had not yet received the title by which he is known in history) Henri recovered Amiens, and checked the Spanish advance. It was noticed that while the old Leaguers came very heartily to the King's help, the Huguenots hung back in a discontented and suspicious spirit. After the fall of Amiens the war languished; the Pope offered to mediate, and Henri had time to breathe. He felt that his old comrades, the offended Huguenots, had good cause for complaint; and in April, 1598, he issued the famous Edict of Nantes, which secured their position for nearly a century. They got toleration for their opinions; might worship openly in all places, with the exception of a few towns in which the League had been strong; were qualified to hold office in financial posts and in the law; had a Protestant chamber in the Parliaments.
Immediately after the publication of the Edict of Nantes, the Treaty of Vervins was signed. Though Henri by it broke faith with Queen Elizabeth, he secured an honourable peace for his country, an undisputed kingship for himself. It was the last act of Philip II., the confession that his great schemes were unfulfilled, his policy a failure.
