How did Oliver Cromwell change peoples ideas?

Oliver Cromwell significantly altered people's ideas about governance and authority during the 17th century by challenging the divine right of kings and promoting the notion of parliamentary sovereignty. His leadership during the English Civil War and subsequent establishment of the Commonwealth emphasized the importance of individual rights and religious freedom, particularly for Puritans. Cromwell's actions and policies fostered a more modern view of government as a representative entity accountable to the people, paving the way for future democratic developments in England. His legacy also sparked debates about the role of military power in politics and the balance between liberty and order.
