The influence of the Italian towns did not make itself greatly felt till after the end of the First Crusade, when it made possible the foundation of a kingdom in Jerusalem, in addition to the three principalities established by Bohemund, Baldwin and Raymond; but during the course of the Crusade itself the Italian ships which hugged the shores of Syria were able to supply the crusaders with provisions and munition of war, and to render help in the sieges of Antioch and Jerusalem.4 Sea-power had thus some influence in determining the victory of the crusaders.
This medieval fortress, strong by art as well as position before the invention of modern artillery, has since undergone numerous sieges.
