Jerusalem collected money through tribute payments, first from the coastal cities which had not yet been captured, and later from other neighbouring states such as Damascus and Egypt, which the Crusaders could not conquer directly. After Baldwin I extended his rule over Oultrejordain, Jerusalem gained revenue from the taxation of Muslim caravans passing from Syria to Egypt or Arabia. The money economy of Jerusalem meant that their manpower problem could be partially solved by paying for mercenaries, an uncommon occurrence in medieval Europe. Mercenaries could be fellow European crusaders, or, perhaps more often, Muslim soldiers, including the famous Turcopoles.
