Cavalier

Cavalier was the name used by Parliamentarians for a Royalist supporter of King Charles I during the English Civil War (1642–1651). (In response, the Royalists called the Parliamentarians Roundheads.) Typically, the term "Cavalier" referred to the high-born supporters of King Charles, who were fond of fashionable, extravagant clothing. Prince Rupert, commander of much of Charles I's cavalry, is often considered an archetypical cavalier.
