Harald Fairhair becomes king
The son of Halvdan the Black, ruler of part of southeastern Norway and a scion of the Yngling dynasty, the ancient royal house of Sweden, Harald succeeded his father at the age of 10. His first conquest came with the suppression of a revolt in the Uplands region. A pact with Haakon, earl of Lade, enabled him to pursue the conquest of the western districts, culminating in the battle of Hafrsfjord, dated 872 by medieval historians but placed 10 to 20 years later by modern historians. -

He proceeded by ceding lands to the Danes who then engaged primarily in trade and built settlements. It is also known that the Danelaw consisted of fifteen shires. -
