John Campbell, 1st Earl of Loudoun was a Scottish politician and Covenanter.

Cromwell's Act of Grace, or more formally the Act of Pardon and Grace to the People of Scotland, was an Act of the Parliament of England that declared that the people of Scotland were pardoned for any crimes they might have committed during the Wars of the Three Kingdoms. It was proclaimed at the Mercat Cross in Edinburgh on 5 May 1654. General George Monck, the English military governor of Scotland, was present in Edinburgh, having arrived the day before for two proclamations also delivered at the Mercat Cross, the first declaring Oliver Cromwell to be the protector of England, Ireland and Scotland, and that Scotland was united with the Commonwealth of England.
