After the capture of Jerusalem at the end of the First Crusade in 1099, the Canons Regular of the Holy Sepulchre were established to take care of the church. The men in charge of securing its defence and its community of canons were called Milites Sancti Sepulcri. Together, the canons and the milites formed part of the structure of which evolved into the modern Equestrian Order of the Holy Sepulchre of Jerusalem. Baldwin I, the first king of Jerusalem, laid the foundations of the kingdom and established its main institutions on the Norman-French pattern as a centralised feudal state.
Tradition maintains that long before the Crusades, a form of knighthood was bestowed upon worthy men at the Church of the Holy Sepulchre. In any case, during the 11th century, prior to the Crusades, "milites sancti Petri" were established to protect Christians and Christian premises in the Occident.-----------------------------------------------------------------------------------------------------------------------------------------------------
