THE CRUSADES, AND THE EAST 181 proceedings were equally certain to be condemned. When he did sail, it was under the papal ban. He made Egypt his objec- tive, since that country was now coming to be g lxtn regarded as the real gate of Palestine. Frederick, Crusade, like a modern statesman, preferred diplomacy to 1229 * fighting, if he could thereby gain his ends ; and in fact he ob- tained from the Egyptian sultan a treaty "which virtually restored to the Christians Jerusalem itself, with other sacred spots, besides the port of Jaffa.
