Adverse possession is one of the most contentious methods of acquiring property, albeit one that has played a huge role in the history of English land. Historically, if someone possessed land for long enough, it was thought that this in itself justified acquisition of a good title. This meant that while English land was continually conquered, pillaged, and stolen by various factions, lords or barons throughout the Middle Ages, those who could show they possessed land long enough would not have their title questioned.
