The question of Charles I's stubbornness raises significant issues about his leadership and potential for negotiation during a tumultuous period. Civil War in England might have been avoided had the king shown more willingness to engage with opposing views. Cromwell, a fierce adversary, argued that Queen Henrietta Maria influenced Charles to adopt a firm stance, which ultimately escalated tensions. Historical interpretations suggest that this close relationship affected the king's decisions, potentially exacerbating conflicts.

However, the popular quote attributed to the queen, urging Charles to maintain firmness both in personal and political arenas, is likely a misrepresentation fueled by contemporary Puritan narratives. While the sentiment reflects her influence, it lacks reliable historical evidence. Thus, the discussion about Charles I's approach to negotiation, influenced by his queen, remains complex and open to interpretation, impacting our understanding of this pivotal moment in history.
