You will wonder how it was that even the careless Robert came to sell his dominions. It happened thus. It had long been the custom for many English people to make journeys to Jerusalem, which were called pilgrimages, in order that they might pray beside the tomb of Our Saviour there. Jerusalem belonging to the Turks, and the Turks hating Christianity, these Christian travellers were often insulted and ill used. The Pilgrims bore it patiently for some time, but at length a remarkable man, of great earnestness and eloquence, called Peter the Hermit, began to preach in various places against the Turks, and to declare that it was the duty of good Christians to drive away those unbelievers from the tomb of Our Saviour, and to take possession of it, and protect it. An excitement such as the world had never known before was created. Thousands and thousands of men of all ranks and conditions departed for Jerusalem to make war against the Turks. The war is called in history the first Crusade, and every Crusader wore a cross marked on his right shoulder.
