Exclusion Crisis
"Roundhead" remained in use to describe those with republican tendencies up until the Exclusion Crisis of 1678–1681; the term was then superseded by "Whig", initially another term with pejorative connotations. Likewise during the Exclusion Bill crisis, the term "Cavalier" was replaced with "Tory", an Irish term introduced by their opponents, and also initially a pejorative term.
