We have the Crusaders (or Franks) who can be used to represent the hordes of pilgrims and knights that flocked to the East following Pope Urban's first call for Crusade in the mid-1090's through to later era forces of soldiers who had grown up in the Holy Land itself. Next there are the Saracens who represent the Islamic Forces who sought the repel the Christian invaders from the Holy Land. ... and finally we have the Military Orders, a compact elite force of professional warriors who were feared across the known world at the time.
This first post will provide a general look at the Crusader faction.
