He found in his states two dominant parties; that of the Reformers, reviving from its ashes, more violent than ever, and having at its head Henry the Great, then king of Navarre; and that of the League, a powerful faction, formed by the princes of the house of Guise, encouraged by the popes, fomented by Philip II. of Spain, whose dangerous policy procured him the name of the Demon of the South, increasing every day by the artifices of the monks, under the veil of zeal for the Catholic religion, but whose principal aim was rebellion. Its leader was the duke of Guise, surnamed le Balafré, from a scar on his cheek, a prince of a brilliant reputation, and who, having more shining qualities than good ones, seemed, in this season of confusion, born to change the destinies of France. Henry III., who perhaps might have crushed both these parties by a judicious exercise of the regal power, absolutely strengthened them by his own weakness. He thought to exhibit a great feat of policy by declaring himself the head of the League; whereas he only proved himself the slave of it. He was forced to make war for the interests of the duke de Guise, whose object was to dethrone him, against the king of Navarre, his brother-in-law and presumptive heir, who only wished to re-establish him in all the rights of his rank. Some successes against the Reformers carried the credit of the too-powerful Balafré to its height. This prince, inflated with his own glory, and strong in the weakness of the king, came to Paris in opposition to the royal command. Then arrived the celebrated day of the _barricades_, in which the people defeated the guards of Henry, and obliged him himself to fly from his capital. Guise did still more; he forced the king to hold the States-General of the kingdom at Blois, and took his measures so well, that he was near sharing the royal authority, with the consent of the representatives of the nation, and with an appearance of the most respectable formalities. Roused by a danger so pressing, Henry III. caused this redoutable enemy, and the cardinal de Lorraine, his brother, still more violent and ambitious than the duke, to be assassinated at the castle of Blois. That which happened to the Protestant party after the St. Bartholomew, now happened to the League; the death of the leaders reanimated the faction. On all parts the Leaguers threw off the mask. Paris closed its gates: nothing was thought or talked of but vengeance. Henry III. was considered as the assassin of the defenders of religion, as an odious, insupportable tyrant, and not as a king who had punished too audacious subjects. The king, pressed on all sides, was at length obliged to seek a reconciliation with Henry of Navarre; in the course of 1589 these two princes encamped in conjunction before Paris.
