Danelaw

• 1. Introduction

  ›

  The Danelaw was the part of England, stretching across Yorkshire, the central and eastern Midlands, and the East of England, where Danish laws rather than Anglo-Saxon laws governed daily life. It was not always a name on a map. The word itself does not appear in surviving records until the early 11th century, as Dena lage, even though the reality it described had been taking shape for well over a hundred years. How did Danish warlords come to govern half of England? What happened when two legal traditions, two languages, and two peoples were forced to share the same island? And what did they leave behind, in the soil, in the words spoken today, and in the genes of the people who live there now?

• 2. The Great Heathen Army

  ›

  In 865, a force unlike any previous Viking raid landed in East Anglia. The armies of several Danish leaders had merged into a single combined force, led by commanders including Halfdan Ragnarsson and Ivar the Boneless, said to be sons of the legendary Viking leader Ragnar Lodbrok. The annals called them the Great Heathen Army. Their arrival was not a raid. They wintered in East Anglia, demanded tribute, and then moved north. By 867 they had captured York, defeating both the recently deposed King Osberht of Northumbria and the usurper Ælla in a single campaign. The Danes then placed an Englishman, Ecgberht I of Northumbria, on the Northumbrian throne as a puppet ruler. Their ambition was total: to conquer the four Anglo-Saxon kingdoms of England. In ten years, they came close. East Anglia fell in 869, when Ivar the Boneless defeated and captured King Edmund at Hoxne. Mercia buckled by 874, when King Burgred fled to Europe after years of failed resistance. That left only Wessex.

• 3. Alfred, Guthrum, and Edington

  ›

  On the 23rd of April 871, King Æthelred of Wessex died, and his younger brother Alfred took the throne. His army was on the verge of collapse and he was forced to pay tribute to the Danes just to buy time. Then, in January 878, the Danish leader Guthrum launched a surprise attack on Alfred's winter quarters at Chippenham. A second Danish army, landing in south Wales, moved to cut off Alfred's retreat. That second force stopped to besiege a small fortress at Countisbury Hill, held by a Wessex ealdorman named Odda. The Saxons attacked the Danes while they slept and defeated them, an unlikely victory that kept Alfred from being trapped between two armies. Alfred went into hiding in the Somerset marshes. By spring he had gathered enough forces to strike back, and he attacked Guthrum at Edington. The Danes were defeated and retreated to Chippenham, where Alfred laid siege and forced surrender. Alfred's terms included a remarkable condition: Guthrum had to accept baptism as a Christian, with Alfred himself serving as godfather. Guthrum agreed. Between 886 and 890, the Treaty of Alfred and Guthrum was formalised, drawing the boundaries of their kingdoms and establishing provisions for peaceful relations, including Danish self-governance in exchange for loyalty to England.

• 4. Law, Land, and the Five Boroughs

  ›

  Five fortified towns shaped the physical core of the Danelaw: Leicester, Nottingham, Derby, Stamford, and Lincoln, broadly delineating the area now called the East Midlands. These strongholds were known as the Five Boroughs, the word borough itself tracing back to the Old English burh, meaning a fortified enclosure, cognate with the German Burg. Inside the Danelaw, a distinctive legal order took shape. Between 30% and 50% of the rural population held the status of sokeman, occupying an intermediate position between free tenants and bond tenants. A sokeman was a free man within a lord's soke, or jurisdiction, and this status tended to provide more autonomy for ordinary people than comparable arrangements elsewhere in England. Legal concepts also overlapped across cultures: the Viking wapentake, the standard unit for dividing land in the Danelaw, was effectively interchangeable with the Anglo-Saxon hundred. The use of an execution site and cemetery at Walkington Wold in east Yorkshire points to a continuity of judicial practice across the cultural boundary. Four of the Five Boroughs eventually became county towns: Leicester gave its name to Leicestershire, Lincoln to Lincolnshire, Nottingham to Nottinghamshire, and Derby to Derbyshire. Only Stamford failed to gain that status, perhaps because of the nearby autonomous territory of Rutland.

• 5. Words in the Landscape

  ›

  Old East Norse and Old English were still somewhat mutually comprehensible when the two peoples met, and their contact left a permanent mark on the English language. The word law itself is a Norse borrowing, as are sky and window, and the third-person pronouns they, them, and their. Many Old Norse words survive today in the dialects of northern England. Contact with Norse is also understood to have encouraged the reduction of Old English's inflectional system, pushing the language toward the more analytic grammar of Middle and Modern English. The landscape encodes the same history. Place-name endings such as -by, meaning village, and -thorp, meaning hamlet, come from Old Norse. The remarkable concentration of Kirby and Kirkby place-names is thought to combine Old Norse kirk, meaning church, with -by, and some of these sites retain the remains of Anglo-Saxon buildings. A particularly striking case is Thynghowe, a Norse word for a meeting place, today located within Sherwood Forest in Nottinghamshire. The site had vanished from modern maps and was essentially lost to history until local enthusiasts Lynda Mallett, Stuart Reddish, and John Wood rediscovered it. English Heritage has since inspected Thynghowe and considers it a national rarity. Experts believe it may also yield clues about the boundary between the ancient Anglo-Saxon kingdoms of Mercia and Northumbria, and they note the site may be even older than the Norse occupation, perhaps reaching back to the Bronze Age.

• 6. Unravelling and Aftermath

  ›

  The Danelaw did not last as a unified political fact. Edward the Elder and his sister Æthelflæd, the Lady of the Mercians, ran a series of military campaigns through the 910s, reclaiming Danish-held territories in the Midlands and East Anglia. Æthelflæd personally took the borough of Derby in 917; Leicester submitted to her the following year. The people of York promised to accept her as overlord, but she died in 918 before that agreement could be realised. Viking rule in the north finally ended in 954, when King Eric was driven out of Northumbria, extinguishing any prospect of a northern Viking kingdom stretching from York to Dublin. Danish interest in England did not disappear. From 1016 to 1035, Cnut the Great ruled a unified English kingdom as part of his North Sea Empire, which also included Denmark, Norway, and part of Sweden. The end of Viking political ambition in England is often marked at the Battle of Stamford Bridge in September 1066, when Harold Godwinson defeated and killed Harald Hardrada of Norway. Three weeks later, William of Normandy defeated Harold at Hastings. As the Danelaw itself finally faded as a legal category, it still appeared in legislation as late as the early 12th century, in the Leges Henrici Primi, where it was named as one of three bodies of law alongside those of Wessex and Mercia into which England was divided.

• 7. Genetics and Archaeology

  ›

  A 10-year genetic study published in 2020 found evidence of a major influx of Danish settlers into England during the Viking period. An earlier effort, a genetic survey commissioned by the BBC in 2000 and conducted by a team from University College London led by Professor David Goldstein for the programme Blood of the Vikings, had concluded that Norse invaders settled sporadically throughout the British Isles, with particular concentrations in places such as Orkney and Shetland. That study deliberately did not try to distinguish the descendants of Danish Vikings from those of Anglo-Saxon settlers, on the grounds that the two groups originated in overlapping areas of the continental North Sea coast, from the Jutland Peninsula to Belgium, making genetic separation difficult. The physical archaeology is sparser than the historical record. Major sites are few; the most famous is York. Another significant Danelaw site is the cremation site at Heath Wood in Ingleby, Derbyshire. Archaeological evidence does not neatly confirm the historically drawn boundaries as a real demographic or trade divide. Scholars suggest this could reflect population movement across the frontier after the treaties were struck, or simply that the boundary, once agreed, was ignored in practice by one or both sides. The rediscovered site at Thynghowe in Sherwood Forest, still under investigation, may yet produce evidence that bridges the gap between the legal map and the human reality on the ground.
