Some twenty years after the death of Hakim, the countries round about the Holy Land began to be harassed by a new and terrible foe. From far-off Turkestan had migrated a fierce fighting tribe, the descendants of one Seljuk, and known to history as the Seljukian Turks. Wherever they went they conquered, until half-way through the eleventh century, their leader drove out the Saracen rulers of Bagdad and made himself Caliph.

His successor was converted to Islam, and with added power, swept over Asia Minor and settled in the city of Nicæa, in threatening proximity to Constantinople.

This invasion was the more terrible in that it brought in its train a relapse to barbarism, for these Turks were barbarians, hordes of robbers and brigands, who cared for nothing but plunder and violence.

Alexios, the weak Emperor of the Eastern Empire, quailed at their approach, and looked on in terror at the spectacle of Christian churches destroyed and Christian children sold into slavery. But he appealed in vain for aid to the kingdom of the West. To unite Western Christendom against a far-off foe was a task beyond the powers of the tottering Empire of the East.

That inspiration, however, was at hand. In 1076, the Seljukian Turks conquered Jerusalem, and at once began a reign of terror for Christian inhabitants and pilgrims. The Patriarch, or Bishop of Jerusalem, was dragged through the street by his white hair, and flung into a dungeon, until his people could gather a sum sufficient to pay his ransom. The holiest sacrament of the Church was profaned by the barbarians, who invaded the buildings and insisted upon sharing in the rite. Pilgrims were stripped and beaten on the roads and passes that led to the Holy City; many suffered martyrdom as they knelt before the Holy Tomb. Out of seven thousand who set out from Germany in one year, only two thousand returned to tell a tale of cruel murder and outrage. The marvel is that such a terrible state of things was allowed to exist so long, without anything being done to remedy it. Pope Gregory VII. (Hildebrand) did indeed gather an army in the latter part of the eleventh century, but his energy was dissipated in the hopeless task of asserting the power of the Pope over the Emperor, and his army was eventually dispersed.

Robert Guiscard, the Norman, actually crossed the sea with his troops in 1081, when death overtook him; and for a time the unhappy pilgrims seemed to be left to their fate. Then suddenly was heard a "voice calling in the wilderness," the voice of one who was to be the herald of the First Crusade.

The story goes that a certain poor hermit named Peter, a native of the French city of Amiens, set out to go to Jerusalem in the year 1098. He had, like every one else, heard of the horrors he might be called upon to endure, but pushed on, undeterred, until, possibly because of his poverty, he arrived safely within the Holy City. He found the condition of things even worse than he expected. The very stones of the great church were stained with the blood of the martyrs; the cries of tortured women rang in his ears; the patriarch Simeon confessed that he had lost heart and was little better than a slave in the Moslem's hands. It was clear that the Emperor of the East, their proper protector, would never act up to his responsibilities. To whom, then, could they look for aid?

"The nations of the West shall take up arms in your cause," cried the dauntless Peter, and he forthwith promised to visit the Pope and obtain his help and sympathy on his return journey, if the Patriarch would give him letters to the Church of Rome.

That night, says the legend, Peter meant to spend in watching at the tomb of the Saviour, and there he fell asleep. And as he slept, the figure of the Redeemer stood before him, and with hand outstretched, bade him hasten to fulfil his great task, saying, "So shalt thou make known the woes of My people, and rouse the faithful to cleanse the Holy Places from the infidel; for through danger and trial of every kind shall the elect now enter the gates of Paradise."

With these words ringing in his ears, the Hermit at once hurried to the coast and sailed for Italy. He came before Pope Urban II. at the very time when the envoys of the Emperor of Constantinople were knocking very hard at the doors of Rome. Urban therefore did not hesitate to bless the enterprise of Peter, and to bid him go forth and preach a Crusade in his own way.
