A Parliament named for these people agreed to a suspension of the king's debt known as the Stop of the Exchequer. The longest serving Parliament in English history was named for these people and passed laws such as the Act of Uniformity that constituted the Clarendon Code. A general who typified the fashions of this group was always accompanied by his allegedly-demonic poodle Boye and was a Count Palatine of the Rhine named Prince (*)  Rupert. Richard Lovelace was part of a school of poets named for this group. The long hair and extravagant dress of these people contrasted with the puritanical habits of their opponents in such battles as Edgehill and Naseby. For 10 points, name these enemies of the Roundheads and supporters of King Charles I in the English Civil War.
