Anglo-Saxon law is a body of written rules and customs that were in place during the Anglo-Saxon period in England, before the Norman conquest. This body of law, along with early Medieval Scandinavian law and Germanic law, descended from a family of ancient Germanic custom and legal thought. However, Anglo-Saxon law codes are distinct from other early Germanic legal statements—known as the leges barbarorum, in part because they were written in Old English instead of in Latin. The laws of the Anglo-Saxons were the second in medieval Western Europe after those of the Irish to be expressed in a language other than Latin.

Medieval Scandinavian law, also called North Germanic law, was a subset of Germanic law practiced by North Germanic peoples. It was originally memorized by lawspeakers, but after the end of the Viking Age they were committed to writing, mostly by Christian monks after the Christianization of Scandinavia. Initially, they were geographically limited to minor jurisdictions (lögsögur), and the Bjarkey laws concerned various merchant towns, but later there were laws that applied to entire Scandinavian kingdoms. Each jurisdiction was governed by an assembly of free men, called a þing.
