To such as these the pope promised that the journey itself should take the place of all penance for sin. The faithful crusader, like the faithful Mohammedan, was assured of immediate entrance into heaven if he died repentant in the holy cause. Later the Church exhibited its extraordinary authority by what would seem to us an unjust interference with business contracts. It freed those who, with a pure heart, entered upon the journey from the payment of interest upon their debts, and permitted them to mortgage property against the wishes of their feudal lords. The crusaders' wives and children and property were taken under the immediate protection of the Church, and he who troubled them incurred excommunication.[128] These various considerations help to explain the great popularity of undertakings that, at first sight, would seem to have promised only hardships and disappointment.

Before spring (1096) those who set forth to preach the Crusade, above all the famous Peter the Hermit, who was formerly given credit for having begun the whole crusading movement, had collected, in France and along the Rhine, an extraordinary army of the common folk. Peasants, artisans, vagabonds, and even women and children, answered the summons, all fanatically intent upon rescuing the Holy Sepulcher, two thousand miles away. They were confident that the Lord would sustain them during the weary leagues of the journey, and grant them a prompt victory over the infidel. The host was got under way in several divisions under the leadership of Peter the Hermit,[129] and of Walter the Penniless and other humble knights. Many of the crusaders were slaughtered by the Hungarians, who rose to protect themselves from the depredations of this motley horde. Part of them got as far as Nicæa, only to be slaughtered by the Turks. This is but an example, on a large scale, of what was going on continually for a century or so after this first great catastrophe. Individual pilgrims and adventurers, and sometimes considerable bodies of crusaders, were constantly falling a prey to every form of disaster--starvation, slavery, disease, and death--in their endeavors to reach the Holy Land.
