After the Battle of Fulford, Harald Hardrada occupied York, the major northern English city at the centre of the campaign.
Fulford was fought just south of York on 20 September 1066. Edwin of Mercia and Morcar of Northumbria were defeated, leaving the city exposed. York’s leaders surrendered and agreed to provide hostages and supplies, while Hardrada’s army withdrew to Stamford Bridge to await them.
The occupation was brief. Harold Godwinson rushed north from London with an army, reached York’s area within days, and caught the Norwegian forces by surprise at Stamford Bridge on 25 September. Hardrada and Tostig were killed, and the surviving Norwegians withdrew from England.
York’s role explains why Fulford mattered strategically: controlling it gave the invaders access to Northumbria and a powerful political centre. The city’s surrender was not the same as a long-term conquest; it lasted only until Harold’s counterattack.
