Two different political groups, the Cavaliers and Roundheads fought for power during the 17th century civil war in England. The Cavaliers put their support behind the king, Charles I. They believed that one man with direction would be better and less confusing then many men fighting over the fate of the country. The Roundheads supported the Parliament, and did not believe that an absolute monarch should run the country. They thought one person having the say over everything would be a good idea.
