The Laws of London, otherwise known as IV Æthelred (abbreviated IV Atr), De institutis Lundonie, the Institutes of London or the London Code, is a medieval English legal text. It has been traditionally assigned to the reign of King Æthelred the Unready (978–1016), but may represent a compilation of a later date, finalised up to a century later. The work provides an important window on, among other topics, the nature of commercial exchange and international contact in London in the tenth and eleventh centuries.[1]
