The period may be divided into four parts: (1) the wars before the establishment of the League (1562-1570); (2) the period of the St. Bartholomew (1570-1573); (3) the struggle of the new Politique party against the Leaguers (1573-1559); (4) the efforts of Henri IV. to crush the League and reduce the country to peace (1589-1595). The period can also be divided by that series of agreements, or peaces, which break it up into eight wars:

1. The war of 1562, on the skirts of which Philip of Spain interfered on one side, and Queen Elizabeth with the Calvinistic German Princes on the other, showed at once that the Huguenots were by far the weaker party. The English troops at Havre enabled them at first to command the lower Seine up to Rouen; but the other party, after a long siege which cost poor Antoine of Navarre his life, took that place, and relieved Paris of anxiety. The Huguenots had also spread far and wide over the south and west, occupying Orleans; the bridge of Orleans was their point of junction between Poitou and Germany. While the strength of the Catholics lay to the east, in Picardy, and at Paris, the Huguenot power was mostly concentrated in the south and west of France. Conde, who commanded at Orleans, supported by German allies, made an attempt on Paris, but finding the capital too strong for him, turned to the west, intending to join the English troops from Havre. Montmorency, however, caught him at Dreux; and in the battle that ensued, the Marshal of France, Saint-Andre, perished; Conde was captured by the Catholics, Montmorency by the Huguenots. Coligny, the admiral, drew off his defeated troops with great skill, and fell back to beyond the Loire; the Duc de Guise remained as sole head of the Catholics. Pushing on his advantage, the Duke immediately laid siege to Orleans, and there he fell by the hand of a Huguenot assassin. Both parties had suffered so much that the Queen-mother thought she might interpose with terms of peace; the Edict of Amboise (March, 1563) closed the war, allowing the Calvinists freedom of worship in the towns they held, and some other scanty privileges. A three years' quiet followed, though all men suspected their neighbours, and the high Catholic party tried hard to make Catherine sacrifice L'Hopital and take sharp measures with the Huguenots. They on their side were restless and suspicious, and it was felt that another war could not be far off. Intrigues were incessant, all men thinking to make their profit out of the weakness of France. The struggle between Calvinists and Catholics in the Netherlands roused much feeling, though Catherine refused to favour either party. She collected an army of her own; it was rumoured that she intended to take the Huguenots by surprise and annihilate them. In autumn, 1567, their patience gave way, and they raised the standard of revolt, in harmony with the heroic Netherlanders. Conde and the Chatillons beleaguered Paris from the north, and fought the battle of St. Denis, in which the old Constable, Anne de Montmorency, was killed. The Huguenots, however, were defeated and forced to withdraw, Conde marching eastward to join the German troops now coming up to his aid. No more serious fighting followed; the Peace of Longjumeau (March, 1568), closed the second war, leaving matters much as they were. The aristocratic resistance against the Catholic sovereigns, against what is often called the "Catholic Reaction," had proved itself hollow; in Germany and the Netherlands, as well as in France, the Protestant cause seemed to fail; it was not until the religious question became mixed up with questions as to political rights and freedom, as in the Low Countries, that a new spirit of hope began to spring up.

The Peace of Longjumeau gave no security to the Huguenot nobles; they felt that the assassin might catch them any day. An attempt to seize Condo and Coligny failed, and served only to irritate their party; Cardinal Chatillon escaped to England; Jeanne of Navarre and her young son Henri took refuge at La Rochelle; L'Hopital was dismissed the Court. The Queen-mother seemed to have thrown off her cloak of moderation, and to be ready to relieve herself of the Huguenots by any means, fair or foul. War accordingly could not fail to break out again before the end of the year. Conde had never been so strong; with his friends in England and the Low Countries, and the enthusiastic support of a great party of nobles and religious adherents at home, his hopes rose; he even talked of deposing the Valois and reigning in their stead. He lost his life, however, early in 1569, at the battle of Jarnac. Coligny once more with difficulty, as at Dreux, saved the broken remnants of the defeated Huguenots. Conde's death, regarded at the time by the Huguenots as an irreparable calamity, proved in the end to be no serious loss; for it made room for the true head of the party, Henri of Navarre. No sooner had Jeanne of Navarre heard of the mishap of Jarnac than she came into the Huguenot camp and presented to the soldiers her young son Henri and the young Prince de Conde, a mere child. Her gallant bearing and the true soldier-spirit of Coligny, who shone most brightly in adversity, restored their temper; they even won some small advantages. Before long, however, the Duc d'Anjou, the King's youngest brother, caught and punished them severely at Moncontour. Both parties thenceforward wore themselves out with desultory warfare. In August, 1570, the Peace of St. Germain-en-Laye closed the third war and ended the first period.

2. It was the most favourable Peace the Huguenots had won as yet; it secured them, besides previous rights, four strongholds. The Catholics were dissatisfied; they could not sympathise with the Queen-mother in her alarm at the growing strength of Philip II., head of the Catholics in Europe; they dreaded the existence and growing influence of a party now beginning to receive a definite name, and honourable nickname, the Politiques. These were that large body of French gentlemen who loved the honour of their country rather than their religious party, and who, though Catholics, were yet moderate and tolerant. A pair of marriages now proposed by the Court amazed them still more. It was suggested that the Duc d'Anjou should marry Queen Elizabeth of England, and Henri of Navarre, Marguerite de Valois, the King's sister. Charles II. hoped thus to be rid of his brother, whom he disliked, and to win powerful support against Spain, by the one match, and by the other to bring the civil wars to a close. The sketch of a far-reaching resistance to Philip II. was drawn out; so convinced of his good faith was the prudent and sagacious William of Orange, that, on the strength of these plans, he refused good terms now offered him by Spain. The Duc d'Alencon, the remaining son of Catherine, the brother who did not come to the throne, was deeply interested in the plans for a war in the Netherlands; Anjou, who had withdrawn from the scheme of marriage with Queen Elizabeth, was at this moment a candidate for the throne of Poland; while negotiations respecting it were going on, Marguerite de Valois was married to Henri of Navarre, the worst of wives [?? D.W.] to a husband none too good. Coligny, who had strongly opposed the candidature of Anjou for the throne of Poland, was set on by an assassin, employed by the Queen-mother and her favourite son, and badly wounded; the Huguenots were in utmost alarm, filling the air with cries and menaces. Charles showed great concern for his friend's recovery, and threatened vengeance on the assassins. What was his astonishment to learn that those assassins were his mother and brother! Catherine worked on his fears, and the plot for the great massacre was combined in an instant. The very next day after the King's consent was wrung from him, 24th August, 1572, the massacre of St. Bartholomew's day took place. The murder of Coligny was completed; his son-in-law Teligny perished; all the chief Huguenots were slain; the slaughter spread to country towns; the Church and the civil power were at one, and the victims, taken at unawares, could make no resistance. The two Bourbons, Henri and the Prince de Conde, were spared; they bought their lives by a sudden conversion to Catholicism. The chief guilt of this great crime lies with Catherine de' Medici; for, though it is certain that she did not plan it long before, assassination was a recognised part of her way of dealing with Huguenots.

A short war followed, a revolt of the southern cities rather than a war. They made tenacious and heroic resistance; a large part of the royal forces sympathised rather with them than with the League; and in July, 1573, the Edict of Boulogne granted them even more than they, had been promised by the Peace of St. Germain.

3. We have reached the period of the "Wan of the League," as the four later civil wars are often called. The last of the four is alone of any real importance.

Just as the Peace of La Rochelle was concluded, the Duc d'Anjou, having been elected King of Poland, left France; it was not long before troubles began again. The Duc d'Alencon was vexed by his mother's neglect; as heir presumptive to the crown he thought he deserved better treatment, and sought to give himself consideration by drawing towards the middle party; Catherine seemed to be intriguing for the ruin of that party—nothing was safe while she was moving. The King had never held up his head since the St. Bartholomew; it was seen that he now was dying, and the Queen-mother took the opportunity of laying hands on the middle party. She arrested Alencon, Montmorency, and Henri of Navarre, together with some lesser chiefs; in the midst of it all Charles IX. died (1574), in misery, leaving the ill-omened crown to Henri of Anjou, King of Poland, his next brother, his mother's favourite, the worst of a bad breed. At the same time the fifth civil war broke out, interesting chiefly because it was during its continuance that the famous League was actually formed.

Henri III., when he heard of his brother's death, was only too eager to slip away like a culprit from Poland, though he showed no alacrity in returning to France, and dallied with the pleasures of Italy for months. An attempt to draw him over to the side of the Politiques failed completely; he attached himself on the contrary to the Guises, and plunged into the grossest dissipation, while he posed himself before men as a good and zealous Catholic. The Politiques and Huguenots therefore made a compact in 1575, at Milhaud on the Tarn, and chose the Prince de Conde as their head; Henri of Navarre escaped from Paris, threw off his forced Catholicism, and joined them. Against them the strict Catholics seemed powerless; the Queen-mother closed this war with the Peace of Chastenoy (May, 1576), with terms unusually favourable for both Politiques and Huguenots: for the latter, free worship throughout France, except at Paris; for the chiefs of the former, great governments, for Alencon a large central district, for Conde, Picardy, for Henri of Navarre, Guienne.

To resist all this the high Catholic party framed the League they had long been meditating; it is said that the Cardinal de Lorraine had sketched it years before, at the time of the later sittings of the Council of Trent. Lesser compacts had already been made from time to time; now it was proposed to form one great League, towards which all should gravitate. The head of the League was Henri, Duc de Guise the second, "Balafre," who had won that title in fighting against the German reiters the year before, when they entered France under Condo. He certainly hoped at this time to succeed to the throne of France, either by deposing the corrupt and feeble Henri III., "as Pippin dealt with Hilderik," or by seizing the throne, when the King's debaucheries should have brought him to the grave. The Catholics of the more advanced type, and specially the Jesuits, now in the first flush of credit and success, supported him warmly. The headquarters of the movement were in Picardy; its first object, opposition to the establishment of Conde as governor of that province. The League was also very popular with the common folk, especially in the towns of the north. It soon found that Paris was its natural centre; thence it spread swiftly across the whole natural France; it was warmly supported by Philip of Spain. The States General, convoked at Blois in 1576, could bring no rest to France; opinion was just as much divided there as in the country; and the year 1577 saw another petty war, counted as the sixth, which was closed by the Peace of Bergerac, another ineffectual truce which settled nothing. It was a peace made with the Politiques and Huguenots by the Court; it is significant of the new state of affairs that the League openly refused to be bound by it, and continued a harassing, objectless warfare. The Duc d'Anjou (he had taken that title on his brother Henri's accession to the throne) in 1578 deserted the Court party, towards which his mother had drawn him, and made friends with the Calvinists in the Netherlands. The southern provinces named him "Defender of their liberties;" they had hopes he might wed Elizabeth of England; they quite mistook their man. In 1579 "the Gallants' War" broke out; the Leaguers had it all their own way; but Henri III., not too friendly to them, and urged by his brother Anjou, to whom had been offered sovereignty over the seven united provinces in 1580, offered the insurgents easy terms, and the Treaty of Fleix closed the seventh war. Anjou in the Netherlands could but show his weakness; nothing went well with him; and at last, having utterly wearied out his friends, he fled, after the failure of his attempt to secure Antwerp, into France. There he fell ill of consumption and died in 1584.

This changed at once the complexion of the succession question. Hitherto, though no children seemed likely to be born to him, Henri III. was young and might live long, and his brother was there as his heir. Now, Henri III. was the last Prince of the Valois, and Henri of Navarre in hereditary succession was heir presumptive to the throne, unless the Salic law were to be set aside. The fourth son of Saint Louis, Robert, Comte de Clermont, who married Beatrix, heiress of Bourbon, was the founder of the House of Bourbon. Of this family the two elder branches had died out: John, who had been a central figure in the War of the Public Weal, in 1488; Peter, husband of Anne of France, in 1503; neither of them leaving heirs male. Of the younger branch Francois died in 1525, and the famous Constable de Bourbon in 1527. This left as the only representatives of the family, the Comtes de La Marche; of these the elder had died out in 1438, and the junior alone survived in the Comtes de Vendome. The head of this branch, Charles, was made Duc de Vendome by Francois I. in 1515; he was father of Antoine, Duc de Vendome, who, by marrying the heroic Jeanne d'Albret, became King of Navarre, and of Louis, who founded the House of Conde; lastly, Antoine was the father of Henri IV. He was, therefore, a very distant cousin to Henri III; the Houses of Capet, of Alencon, of Orleans, of Angouleme, of Maine, and of Burgundy, as well as the elder Bourbons, had to fall extinct before Henri of Navarre could become heir to the crown. All this, however, had now happened; and the Huguenots greatly rejoiced in the prospect of a Calvinist King. The Politique party showed no ill-will towards him; both they and the Court party declared that if he would become once more a Catholic they would rally to him; the Guises and the League were naturally all the more firmly set against him; and Henri of Navarre saw that he could not as yet safely endanger his influence with the Huguenots, while his conversion would not disarm the hostility of the League. They had before, this put forward as heir to the throne Henri's uncle, the wretched old Cardinal de Bourbon, who had all the faults and none of the good qualities of his brother Antoine. Under cover of his name the Duc de Guise hoped to secure the succession for himself; he also sold himself and his party to Philip of Spain, who was now in fullest expectation of a final triumph over his foes. He had assassinated William the Silent; any day Elizabeth or Henri of Navarre might be found murdered; the domination of Spain over Europe seemed almost secured. The pact of Joinville, signed between Philip, Guise, and Mayenne, gives us the measure of the aims of the high Catholic party. Paris warmly sided with them; the new development of the League, the "Sixteen of Paris," one representative for each of the districts of the capital, formed a vigorous organisation and called for the King's deposition; they invited Henri, Duc de Guise, to Paris. Soon after this Henri III. humbled himself, and signed the Treaty of Nemours (1585) with the Leaguers. He hereby became nominal head of the League and its real slave.
