What was feudalism in France?

France saw large properties broken down into smaller properties with lesser nobility in charge. The nobles worked out various fee structures for use of land, mills, and fees to use woodlands. France's structure was so loose, that it was possible for a vassal to pledge to two or more overlords. This prompted the development of the 'liege lord' concept, which was sort of a pecking order in terms of who would be the primary lord the vassal would commit to.
