On This Day in British History:
The Battle of Stamford Bridge, 25th September 1066 with some consideration of the subsequent Battle of Hastings, 14th October 1066
King Harold II (1022-1066), Harold Godwinson – Anglo-Saxon King of England (6th January 1066 – 14th October 1066) – led the English army to victory, defeating the invading Norwegian forces led by King Harald Hardrada and Harold’s brother, the exiled Earl of Northumbria Tostig at Stamford Bridge in York.
Harold Godwinson who became a powerful earl upon the death of Godwin, Earl of Wessex (his father). Upon the death of Edward the Confessor, Harold was selected by the Witenagemot (the Witan, ‘wise men’ – the Anglo-Saxon king’s council between the 7th and 11th centuries) [see footnote 1]. Harold II is suspected of being the first king coronated at Westminster Abbey, though historians are uncertain of this. Harold had a short but turbulent reign. Crowned King on the 6th January, 9 months later he would have to fight off other claimants to the throne, and a month later attempt to repel William, Duke of Normandy’s invasion.
However, early in his reign, Harold had set solidified his power and strengthened his military power early on: repelling his brother Tostig’s numerous raids and even raising a large army stationed along the south coast ready for an invasion by William the Conqueror . In his excellent book on the history of English monarchs, David Mitchel writes:
“It was at the height of the campaign season and he was ready for William. Annoyingly, William didn’t turn up [.] By early September, Harold’s troops had run out of food and he had to let them go home. Still, the year was getting on, the weather was likely to worsen, so there was a decent chance, [Harold] must have thought, that William wasn’t going to invade after all. [Instead of William, the imminent invasion came, once again, from the Vikings! Tostig had convinced the King of Norway, Harald Hardrada (“hard ruler”) to invade England. Turning his attention away from William. Harold] reassembled his extremely recently disbanded army [and] marched north so quickly that he caught Harald and Tostig on the hop. At the Battle of Stamford Bridge, just east of York, the Norwegians didn’t even have a chance to put on their chain mail. They were brutally and bloodily defeated. Both Tostig and the previously invincible Harald were killed” (Mitchell, 2023, pp.107-108). [See footnote 2]

Causes of the Battle
The battle was primarily caused by a succession crisis following the death of Edward the Confessor in January 1066. Harold Godwinson was crowned king, but his claim was contested by several others, including Harald Hardrada of Norway. Tostig, Harold’s estranged brother, allied with Hardrada, hoping to reclaim his earldom in Northumbria.
The Battle
Harold Godwinson’s forces marched rapidly from the south of England to confront the invaders, covering around 185 miles in just four days. The English army launched a surprise attack on the Vikings, who were caught off guard and unprepared for battle. Despite initial resistance, the English forces ultimately triumphed, killing both Hardrada and Tostig.
Aftermath
Although Harold Godwinson achieved a decisive victory at Stamford Bridge, his army was significantly weakened. This left them vulnerable to the Norman invasion led by William the Conqueror, which culminated in the Battle of Hastings just a few weeks later.
William the Conqueror (William, Duke of Normandy) is said to have based his claim to the throne (succession rights) by:
“William based his claim on being Edward [the Confessor’s] cousin. [Edward’s] mother, Emma, was the daughter of Duke Richard I of Normandy, who was William’s great-grandfather. Edward also owed his throne to the assistance William had given him to return of England in 1042, and in 1051 the Confessor is said to have made William his hair. Furthermore, William claimed that Harold Godwinson had paid him homage while in Normandy in 1064.” (Grant, Kay, et al. 2019, p.68)
