English Civil War

185,000

estimated total dead

English Heritage estimates up to 200,000 soldiers and civilians died in England, largely from fighting and disease. Wider three-kingdom mortality—especially in Ireland—is substantially higher and remains disputed; this page’s 185,000 allocation is an England-focused estimate.
