Harold III of Denmark (The Danish North Sea)

King Harold III of Denmark (also known as Harold Harefoot) reigned as the King of Denmark and East Anglia for five years. Harold only ascended to the throne as his brother Svein Knutsson was captured and killed by rebels in Norway, and he remained in charge of the realms as his brother, Canute, was fighting against the rebellion. Another rebellion broke out in East Anglia, supported by Harold's stepbrothers, Prince Alfred and King Edward III of Wessex, and King Harold traveled to England to suppress the rebellion. Alfred was captured by earl Godwin, who had him seized and delivered to an escort of men loyal to Harefoot. While en route to Ely he was blinded and soon after died of his wounds. Harold died in 1040, having ruled just five years; his half-brother Harthacnut soon returned and took hold of East Anglia peacefully. These events began the Wessex-Danish War.
