Tostig Godwinson, younger brother of King Harold II was the third son of the powerful Earl Godwine of Wessex and his Danish wife Gytha, the daughter of Thorkell Sprakaleg.
Along with his father and brothers, Tostig was banished from England in 1051 by the Saxon king Edward the Confessor but forcefully returned in 1052. On the death of Earl Siward three years later, he was appointed Earl of Northumbria, Northamptonshire and Huntingdonshire.
He rebelled against Harold and fought alongside Viking forces at the battle of Stamford bridge, where he was slain in battle.
