“ Pilgrims were insulted and persecuted in every way. The churches in Jerusalem were destroyed or turned into stables. Now, if it were a meritorious thing to make a pilgrimage to the Holy Sepulchre, much more would it be a pious act to rescue the sacred spot from the profanation of infidels. This was the conviction that changed the pilgrim into a warrior,—this the sentiment that for two centuries and more stirred the Christian world to its profoundest depths, and cast the population of Europe in wave after wave upon Asia. ”
