Oath of Abjuration
Originating under William III in 1690 and made compulsory in 1701, this required holders of public office in England, such as members of Parliament, lawyers, and clergy, to renounce the claims of the recently overthrown Stuart dynasty. It was reimposed under Hanoverian kings, when in addition Roman Catholics had to reject papal claims to jurisdiction in England. The oath was later modified in order to give relief to Roman Catholics, Jews, and others.
