 The Kingdom at first was virtually bereft of a loyal subject population and had few knights to implement the laws and orders of the realm.With the arrival of Italian trading firms, the creation of the military orders, and immigration by European knights, artisans, and farmers, the affairs of the Kingdom improved and a feudal society developed, similar to but distinct from the society the crusaders knew in Europe.The nature of this society has long been a subject of debate among crusade historians.
