Uner the system of feudalism, a fiefdom, fief, feud, feoff, or fee, often consisted of inheritable lands or revenue-producing property granted by a liege lord, generally to a vassal, in return for a form of allegiance, originally to give him the means to fulfill his military duties when called upon. However anything of value could be held in fief, such as an office, a right of exploitation (e.g., hunting, fishing) or any other type of revenue, rather than the land it comes from.
