Where/who did medieval Englands feudal system come from?
The feudal system was introduced into England by William the Conqueror and his followers after the Norman Conquest of 1066.A perfect indication of this is the so called Doomsday Book, which William had compiled (at great pains) in the 1080s.Such a record, and the effort and resources which went into compiling it, is meaningless outside the context of a feudal system of rule.
