What are the differences between the roundheads and the cavaliers.

Roundheads were Parliamentary/Puritan soldiers who wore tight fitting un-orimented metal helmets, while Cavaliers were kings men who wore large hats with feathers as their uniform headdress.

Some differences between the round-heads and the cavaliers are that the cavaliers supported the King and the round-heads supported Parliament.

The Cavaliers fight in the battle field, The roundheads is an insulting nickname for parliment members in England since their haircuts made their heads look round.
