the domain controlled by a feudal lord

Under 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 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 a revenue rather than the land it comes from.
