 In 1000, the English king, Ethelred the Unready, taking advantage of a temporary absence of the Danes in southern England, invaded Strathclyde/Cumbria for reasons unknown.After the takeover of the English throne by Cnut in 1015/16, the northern region became more disturbed than ever, with the fall of the Bamburgh earls and the defeat of the Northumbrian earl by the Scots and Cumbrians at the Battle of Carham in 1018.Attempts by the Scots and Cnut to control the area ended with Siward, Earl of Northumbria emerging as a strongman.
