Allodium

Allod, deriving from Frankish alōd meaning "full ownership", also known as allodial land was, in medieval and early modern European feudal law, a form of property ownership where the owner had full and absolute title. The allodial landowner, also known as an allodiary or hereditary lord, had the right to alienate the property, which was almost always land, a city plot, or an estate, and owed no feudal duties to any other person in respect of it.
