Coronation Oath Act 1688

Coronation Oath Act 1688

The Coronation Oath Act 1688 (1 Will & Mary c 6) is an Act of the Parliament of England. It was passed in 1689. The preamble noted that "by the Law and Ancient Usage of this Realm" the monarchs of England had taken a solemn oath at their coronation to maintain the statute laws and customs of the country and of its inhabitants, but the text of this oath had become partly meaningless over time, "framed in doubtful Words and Expressions with relation to ancient Laws and Constitutions at this time unknown". It established a single uniform oath to be taken by future monarchs at their coronation, and also established that this oath was to be taken by William III and Mary II when they were crowned. The oath was fundamentally different from the traditional coronation oath which recognized laws as being the grant of the King whereas the Act's oath sought the King to rule according to the law agreed in parliament. The oath was shorter than the one used in 1660, removing a number of awkward phrases and references to past monarchs; a significant alteration was the explicit inclusion of an oath to maintain "the true Profession of the Gospel and the Protestant Reformed Religion Established by Law", rather than the somewhat more vague promise to "Protect and Defend the Bishops and Churches under Government."

This Act was partly in force in Great Britain at the end of 2010.
