The King of Spain was the brother of Anne of Austria. His first wife, the mother of Maria Theresa, was sister of Louis XIII., and consequently aunt of Louis XIV. Thus there was a peculiar bond of relationship between the French and Spanish courts. Still Louis was unrelenting in the vigorous action upon which he had entered. In addition to the hostile measures already adopted, a special messenger was sent to Philip IV. to inform him that, unless he immediately recognized the supremacy of the French court, and made a formal apology for the insult offered the French minister, war would ensue. The Spanish king, unwilling, for so trivial a cause, to involve the two nations in a bloody conflict, very magnanimously yielded to the requirements demanded by the hot blood and wounded pride of his son-in-law. In the presence of all the foreign ministers and the assembled court at Fontainebleau, the Spanish embassador made a humble apology, and declared that never again should the precedence of the embassador of France be denied. A very similar difficulty occurred a short time after at Rome. The French embassador there, the Duke of Crequi, an old feudal noble, accompanied by troops of retainers armed to the teeth, had, by his haughty bearing, become extremely unpopular both with the court and the people of Rome. The myrmidons of the duke were continually engaged in night-brawls with the police. On one occasion they even attacked, sword in hand, the Pope's guard, and put them to flight. The brother of Pope Alexander VII., who hated Crequi, instigated the guard to take revenge. In an infuriated mob, they surrounded the palace of the embassador, and fired upon his carriage as it entered his court-yard. A page was killed, and several other attendants wounded. Crequi immediately left the city, accusing the Pope of instigating the outrage. Louis XIV. demanded reparation, and the most humble apology. The proud Pope was not disposed to yield to his insolent demands. Affairs assumed so threatening an aspect, that the Pope ordered two of the guard, one an officer, to be hung, and the Mayor of Rome, who was accused of having instigated the outrage, to be banished. This concession, however, by no means satisfied the irascible Louis. He commenced landing troops in Italy, threatening to besiege Rome. The Pope appealed to the Roman Catholic princes of Germany for aid. They could not come to his rescue, for they were threatened with war by the Turks. The unhappy Pope was thus brought upon his knees. He was compelled to banish from Rome his own brother, Don Mario Chigi, and to send an embassador to Paris with the most humble apology. These events were but slight episodes in the gay life of the pleasure-loving king. He was still reveling in an incessant round of feasting and dancing, flitting with his gay court from one to another of his metropolitan and rural palaces.
