The Parliamentarians won the war. Charles I was captured, put on trial and in 1649 he was executed. His son Charles II then tried to take over the country, but lost and escaped abroad. As a result, the three kingdoms spent 11 years without a king. For most of this time, they were run by Oliver Cromwell, a former Parliamentarian general. After Cromwell's death, the monarchy was restored under Charles II. However, kings were never as powerful as they had been before the war.
