The document summarizes the events leading up to the English Civil War between King Charles I and Parliament. It describes how King James I believed in the divine right of kings and often argued with Parliament over money and religion. His son Charles I continued these disputes and tried to arrest Parliament's leaders in 1642, sparking the Civil War between the Royalist Cavaliers and Parliamentarian Roundheads. Oliver Cromwell led the Roundheads to victory over the Cavaliers and King Charles, who was executed in 1649. Cromwell then ruled England as Lord Protector until his death in 1658.
