Frederick, who had sent vessels, provisions, and soldiers to the holy war, thought that he had fully performed his part in the crusade, and was at first much astonished at the reproaches of the Holy See. When the pope threatened him with the anger of Heaven and the thunders of Rome, he could not restrain his indignation; in his letters the emperor complains bitterly of the tyranny of both Innocent and Honorius, and talks of opposing war to war, and vengeance to injustice. After this, Honorius, who acted less from the dictates of his own mind than after the policy of his predecessors, changed his tone, attempted to justify both Innocent and himself, and, employing prayers instead of menaces, conjured Frederick to have pity on the Church of the East. This paternal language appeased Frederick; in an interview which he had with the pope at Veroli, the emperor of Germany repeated his vow to repair to Palestine at the head of an army. In another assembly, which was held some time afterwards at Verona, the pope endeavoured to engage Frederick, on account of his own interests; he proposed to him to espouse Yolande, daughter of John of Brienne, and heir to the kingdom of Jerusalem. The grand masters of the Templars, the Hospitallers, and the Teutonic order, with the patriarch and the king of Jerusalem, all summoned to Italy to deliberate on the affairs of the crusade, approved of a union which would secure them the assistance of a powerful monarch. Frederick accepted a kingdom which he promised to defend, and consented to undergo excommunication if he failed in his promises. After the conference of Verona, King John of Brienne visited the principal states of Europe, for the purpose of soliciting aid for the Holy Land. At the time of John’s arrival in France, the French were mourning the death of Philip Augustus. The king of Jerusalem assisted at the funeral ceremonies of his master and benefactor, who, at his death, had bequeathed three thousand silver marks to the defenders of Palestine. After having paid the last duties to Philip, John went first to England, and afterwards to Germany, in both of which countries his presence and his discourses strongly moved Christians with the misfortunes of the Holy Land.
