By the time the Crusaders took Jerusalem, it had lost virtually all its native residents. Much of the Christian population had either fled or been expelled during the Frankish advance on the city and in the final onslaught remaining Muslims and Jews were killed or held for ransom. A major difficulty facing the new rulers of the city, therefore, was how to repopulate it. During the siege, the Crusading army had numbered perhaps over 40,000 people, including women and children; but once the city was taken and Crusading vows fulfilled, the army quickly dispersed. A year later, King Baldwin I's chaplain, Fulcher of Chartres, remarked that there were no more than 300 knights and as many foot-soldiers distributed between Jerusalem, Jaffa, Ramla and Haifa 2 . The city's population in the early years of the 12 th century may therefore have numbered hundreds rather than thousands.
