The pope being delivered from the cares of this political crusade, turned his attention to the holy one beyond the seas; his legates solicited various princes, some to take the cross, others to accomplish their vows. Clement did not neglect to press Michael Palæologus to prove the sincerity of his promises. Charles, who was the acknowledged vassal of the pope, and who owed his kingdom to him, received many messages, representing the dangers of the Holy Land, and reminding him of what he owed to Jesus Christ, who was outraged by the victories of the Mussulmans. The new king of Sicily contented himself with sending an embassy to the sultan of Cairo, and with commending the unfortunate inhabitants of Palestine to the mercy of Bibars. The sultan replied to Charles, that he did not reject his intercessions; but the Christians were destroying themselves with their own hands; that no one among them had the power to enforce the observance of treaties, and that the most contemptible of them were constantly undoing that which the greatest had done. Bibars, in his turn, sent ambassadors to Charles, less for the purpose of following up any negotiations, than to obtain information upon the state and views of Christendom.[18]

Young Conradin, who was preparing to dispute the crown of Sicily with Charles of Anjou, in order to avail himself of every means of supporting his claim, sent deputies to the sultan of Cairo, in the character of king of Jerusalem, conjuring him to protect his rights against his rival. Bibars, in his reply, pretended to endeavour to console Conradin, but, doubtless, received with joy these proofs of the divisions that existed among the princes of Europe.

In the state in which Europe then was, one monarch alone took serious interest in the fate of the Christian colonies of Asia. The remembrance of a land in which he had so long dwelt, and the hope of avenging the honour of the French arms in Egypt,[19] once more directed the thoughts of Louis IX. to a new crusade. He however concealed his purpose, and this great project, says one of his historians,[20] was formed, so to say, between God and himself. Louis consulted the pope, who hesitated to answer him, reflecting upon the dangers that his absence might bring upon France, and even upon Europe. The first letter of Clement[21] aimed at diverting the French monarch from so perilous an enterprise; but, upon being consulted again, the sovereign pontiff showed none of the same scruples, and declared it to be his duty to encourage Louis in his design, as he was persuaded, he said, that this design came from God.

The purpose, however, of this negotiation remained still buried in profound mystery. Louis, no doubt, was fearful of prematurely announcing his designs, lest reflection might weaken the enthusiasm of which he must stand in so much need, or that a powerful opposition to the undertaking of a crusade might be formed in both his court and his kingdom; he thought that, by announcing his project unexpectedly, at the moment of its being ripe for execution, he should affect men’s minds more forcibly, and induce them more easily to follow his example. An assembly of the barons, nobles, and prelates of the kingdom was solemnly convoked at Paris towards the middle of Lent. The faithful Joinville was not forgotten in this convocation; the seneschal foresaw, he says in his Memoirs, that Louis was about to take the cross, and the cause of his having this presentiment was, that in a dream he had seen the king of France clothed in a chasuble of a bright red colour, made of Rheims serge, which signified the cross. His almoner, when explaining this dream to him, added, that the chasuble being of Rheims serge, denoted that the crusade would be but a trifling or small exploit.

On the twenty-third day of March, the great parliament of the kingdom being assembled in a hall of the Louvre, the king entered, bearing in his hand the crown of thorns of Christ. At sight of this, the whole assembly became aware of the monarch’s intentions. Louis, in a speech delivered with great animation, described the misfortunes of the Holy Land, and proclaimed that he was resolved to go and succour it; he then exhorted all who heard him to take the cross. When he ceased to speak, a sad but a profound silence expressed at once the surprise and grief of the barons and prelates, with the respect that all entertained for the will of the holy monarch.

Cardinal de St. Cecilia, the pope’s legate, spoke after him, and in a pathetic exhortation, called upon the French warriors to take arms. Louis received the cross from the hands of the cardinal, and his example was followed by three of his sons. Among these princes, the assembly was affected at beholding John, count of Nevers, who was born at Damietta amidst the calamities of the preceding crusade. At the same time the legate received the oath of John, count of Brittany, of Alphonso de Brienne, count of Eu, of Marguerite, the ancient countess of Flanders, and of a great number of prelates, nobles, and knights.

The determination of St. Louis, of which a sad presentiment had been entertained, spread deep regret throughout his kingdom; his people could not behold without sorrow the departure of a prince whose presence alone preserved peace, and maintained order and justice everywhere. The health of the king was very much weakened, and there was great reason to fear that he would not be able to support the dangers and fatigues of a crusade; he took his sons with him; which circumstance added greatly to the public grief. The disasters of the first crusade were still fresh in the memory of his subjects, and whilst they thought of the captivity of the whole of the royal family, they dreaded greater misfortunes in the future. Joinville does not fear to say, “that they who had advised the king to undertake this voyage beyond the seas, had sinned mortally.”

Notwithstanding the general regret, there were neither complaints nor murmurs against the king; the spirit of resignation, which was one of the virtues of the monarch, appeared to have passed into the minds of all his subjects, and, to employ the very expressions of the pope’s bull, “the French people saw in the devotion of their king nothing but a noble and painful sacrifice to the cause of the Christians, to that cause for which God had not spared his only Son.”

The greater that was the affection for the king, the greater was the general grief; but the zeal to partake his perils more than kept pace with these.[22] Louis alone thought of delivering the tomb of Christ and the Christian colonies; the warlike nobility of the kingdom only thought of following their king in an expedition which was already looked upon as unfortunate.
