Answer:
The Royalists and the Roundheads.
Step-by-step explanation:
The English Civil War of 1642-1645 was a series of civil wars between Parliamentarians and Royalists. The Parliamentarians were also called "Roundheads," while the Royalists were also called "Cavaliers." The conflict arose because of the different opinions that these people had when it came to the way in which England should be governed. The war ended with the Parliamentarian victory at the Battle of Worcester on September 3, 1651.
