Hakim despised Mahomet, but the Mussulmans were too numerous in his states to allow him to think of persecuting them. The god trembled for the authority of the prince, and allowed all his anger to fall upon the Christians, whom he gave up to the fury of their enemies. The places which the Christians held in the administration, and the abuses introduced into the mode of levying the imposts, with which duty they were charged, had drawn upon them the hatred of all the Mussulmans. When the caliph Hakim had once given the signal for persecution, he found himself at no loss for executioners. At first, they who had abused their power were the objects of pursuit; the Christian religion became the next crime, and the most pious among the faithful were deemed the most guilty. The blood of the Christians flowed in all the cities of Egypt and Syria, their courage in the midst of torments only adding to the hatred of their persecutors. The complaints which escaped them in their sufferings, the prayers, even, which they addressed to Jesus Christ to put an end to their evils, were considered as a revolt, and punished as the most guilty treasons. It is probable that motives of policy joined with those of fanaticism in the persecution of the Christians. Gerbert, archbishop of Ravenna, who had become pope, under the name of Sylvester II., had witnessed the ills to which the faithful were subjected in their pilgrimages to Jerusalem. On his return he excited the nations of the West to take up arms against the Saracens. In his exhortations, he made Jerusalem herself speak, made her deplore her misfortunes, and conjure her Christian children to hasten and break her chains. The people were deeply moved with the complaints and groans of Sion. The Pisans, the Genoese, with Boson, king of Arles, undertook a maritime expedition against the Saracens, and made an incursion upon the coasts of Syria. These hostilities, and the number of the pilgrims, which increased every day, might well create distrust in the masters of the East. The Saracens, alarmed by sinister predictions, and by the imprudent menaces of the Christians, saw nothing but enemies in the disciples of Christ; from that time terror and death guarded the gates of Jerusalem.
