The civil wars that raged across England, Ireland, Scotland and Wales from 1638 to 1651 began with conflict between King Charles I and his parliaments over the scope of royal authority and the direction of the post-Reformation Church of England. There were multiple and complex causal factors that led to war, including the personalities of the king and his chief advisors. One consequence was the king's execution in front of a crowd of thousands on a cold January morning in 1649. But this was a bloody revolution for Charles I's subjects as well as for the king himself. Direct and indirect total war dead from the civil wars in England has been estimated at 180,000 (3.6 per cent of the population) with estimated proportions higher still in Scotland and Ireland. The civil wars created widespread turmoil and destruction that spread far beyond the battlegrounds. It is thought that one out of every four adult males took up arms, representing the departure of many fathers, brothers, uncles and nephews who were gone to kill or be killed. Contemporaries perceived that the conflict tore through the fabric of society to the very core of the family unit. Sir John Oglander wrote for posterity in his commonplace book, ‘Thou wouldest think it strange if I should tell thee there was a time in England when brothers killed brothers, cousins cousins, and friends their friends […] When thou wentest to bed at night, thou knewest not whether thou shouldest be murdered afore day.’
