King James I dealt with issues of money and religion with Parliament. His son, Charles I, dissolved Parliament when they refused to raise taxes for his wars, leading to conflict over royal powers. This resulted in the English Civil War between Royalists and Parliamentarians led by Oliver Cromwell. Charles I was captured, tried for treason, and executed. Cromwell established a republic that was a dictatorship under his rule. After his death, the monarchy was restored but with new limits on royal power defined by the Bill of Rights.
