How did Oliver Cromwell affect peoples lives?

Oliver Cromwell significantly impacted people's lives in 17th-century England through his role in the English Civil War and as Lord Protector. His leadership led to the establishment of a republican government, which altered the political landscape and diminished the monarchy's power. Cromwell's Puritan beliefs influenced societal norms, promoting a more austere lifestyle while also fostering religious tolerance for certain Protestant groups. However, his military campaigns, particularly in Ireland, resulted in significant suffering and displacement for many, leaving a complex legacy.
