Siward Defeats Macbeth

Date: July 27, 1054 • Location: Musselburgh, United Kingdom

During his invasion of Scotland, Siward, Earl of Northumbria, defeated Macbeth, King of Scotland, in an engagement north of the Firth of Forth.

Siward or Sigurd was an important earl of 11th-century northern England. The Old Norse nickname Digri and its Latin translation Grossus are given to him by near-contemporary texts. He emerged as a regional strongman in England during the reign of Cnut. Cnut was a Scandinavian ruler who conquered most of England in the 1010s, and Siward was one of many Scandinavians who came to England in the aftermath, rising to become sub-ruler of most of northern England. From 1033 at the latest, he was in control of southern Northumbria, present-day Yorkshire, governing as earl on Cnut's behalf.
