After the execution of Charles I, England was left without a monarch. So Oliver Cromwell took charge and became Lord protector, he refused the title of king because he believed that God appointed kings and he was not a royal. Cromwell was a villian in some people's eyes and a hero in others. He changed the country's religion to Puritanism(Protestantism), he allowed people to be whatever religion they wanted to be as long as they kept it to themselves and he made parliament a much stronger democratic unit but he killed mamy innocent Irish Catholics and sent young children to the west indies to work. After Oliver Cromwell came his son Richard Cromwell, Richard did not live up to his father's standards and parliament decided that it was right to make Charles II king.
