Oliver Cromwell: life and legacy

Life and career

As Lord Protector he led a military-backed republic and pursued Protestant foreign policy. His campaigns in Ireland involved massacres and conquest that remain central to his contested legacy.

Historical context

Legacy and interpretation

Oliver Cromwell's reputation has been shaped by commemoration, political argument and the survival of unequal evidence.
