Danelaw

The Danelaw , as recorded in the Anglo-Saxon Chronicle, was the part of England in which the laws of the Danes held sway and dominated those of the Anglo-Saxons. Danelaw contrasts with West Saxon law and Mercian law. The term is first recorded in the early 11th century as Dena lage. Modern historians have extended the term to a geographical designation. The areas that constituted the Danelaw lie in northern and eastern England, long occupied by Danes and other Norsemen.
The Danelaw originated from the Viking expansion into England of the 9th century, although the term was not used to describe a geographic area until the 11th century. With the increase in population and productivity in Scandinavia, Viking warriors, having sought treasure and glory in the nearby British Isles, "proceeded to plough and support themselves", in the words of the Anglo-Saxon Chronicle for the year 876.
