Allodial titleAllodial title constitutes ownership of real property (land, buildings, and fixtures) that is independent of any superior landlord. Allodial title is related to the concept of land held "in allodium", or land ownership by occupancy and defense of the land. Most property ownership in common law jurisdictions is fee simple. In the United States, the land is subject to eminent domain by federal, state and local government, and subject to the imposition of taxes by state and/or local governments, and there is thus no true allodial land.
Quia EmptoresQuia Emptores is a statute passed by the Parliament of England in 1290 during the reign of Edward I that prevented tenants from alienating their lands to others by subinfeudation, instead requiring all tenants who wished to alienate their land to do so by substitution. The statute, along with its companion statute Quo Warranto also passed in 1290, was intended to remedy land ownership disputes and consequent financial difficulties that had resulted from the decline of the traditional feudal system in England during the High Middle Ages.
Land tenureIn common law systems, land tenure, from the French verb "tenir" means "to hold", is the legal regime in which land owned by an individual is possessed by someone else who is said to "hold" the land, based on an agreement between both individuals. It determines who can use land, for how long and under what conditions. Tenure may be based both on official laws and policies, and on informal local customs (insofar higher law does allow that).
EscheatEscheat ᵻsˈtʃiːt is a common law doctrine that transfers the real property of a person who has died without heirs to the crown or state. It serves to ensure that property is not left in "limbo" without recognized ownership. It originally applied to a number of situations where a legal interest in land was destroyed by operation of law, so that the ownership of the land reverted to the immediately superior feudal lord. The term "escheat" derives ultimately from the Latin ex-cadere, to "fall-out", via mediaeval French escheoir.
SerfdomSerfdom was the status of many peasants under feudalism, specifically relating to manorialism, and similar systems. It was a condition of debt bondage and indentured servitude with similarities to and differences from slavery, which developed during the Late Antiquity and Early Middle Ages in Europe and lasted in some countries until the mid-19th century. Unlike slaves, serfs could not be bought, sold, or traded individually though they could, depending on the area, be sold together with land.
Norman ConquestThe Norman Conquest (or the Conquest) was the 11th-century invasion and occupation of England by an army made up of thousands of Norman, Breton, Flemish, and French troops, all led by the Duke of Normandy, later styled William the Conqueror. William's claim to the English throne derived from his familial relationship with the childless Anglo-Saxon king Edward the Confessor, who may have encouraged William's hopes for the throne. Edward died in January 1066 and was succeeded by his brother-in-law Harold Godwinson.
