The concept, idea or philosophy of property underlies all property law. In some jurisdictions, historically all property was owned by the monarch and it devolved through feudal land tenure or other feudal systems of loyalty and fealty to the monarch.
The French Revolution introduced the idea of the absolute ownership of property, it is such ownership that was introduced into the civil law by the Code Napoleon. This is in contradistinction with the ideas of property in common law that remained tied to their feudal past.
