Historian A: David Carpenter – Political and Military Perspective "Harald Hardrada’s invasion of England in 1066 was primarily driven by his ambition to expand his power and reputation. As a seasoned military leader and the King of Norway, he sought to secure his dynasty’s influence in Britain. According to Carpenter, Harald’s decision was motivated by territorial ambitions and the desire to challenge English resistance, which ultimately led to his downfall at Stamford Bridge. His invasion was a strategic move within the wider context of Scandinavian efforts to control parts of Britain, demonstrating the importance of military strength and political ambition in shaping history."

Historian B: Helen Castor – Social and Cultural Perspective "Harald Hardrada’s claim to the throne reflects the complex social and cultural landscape of the Viking Age. Castor emphasizes the significance of Viking traditions, the importance of kinship ties, and Harald’s reputation among his followers. She argues that Harald’s motivations were as much about maintaining his personal honour and legacy as about territorial conquest. His invasion was also a reflection of Viking values, such as loyalty to leaders and the pursuit of glory, which influenced his actions and the collective identity of Norse society at the time."
