Exclusion Crisis
Cavalier remained in use as a description for members of the party that supported the monarchy up until the Exclusion Crisis of 1678–1681 when the term was superseded by "Tory" which was another term initially with pejorative connotations. Likewise, during the Exclusion Bill crisis, the term Roundhead was replaced with "Whig", a term introduced by the opponents of the Whigs and also was initially a pejorative term.
