"The Monmouth Rebellion, also known as The Revolt of the West or The West Country rebellion, was an attempt to overthrow James II, who had become King of England, Scotland and Ireland upon the death of his elder brother Charles II on 6 February 1685. James II was a Roman Catholic, and some Protestants under his rule opposed his kingship. James Scott, 1st Duke of Monmouth, an illegitimate son of Charles II, claimed to be rightful heir to the throne and attempted to displace James II."--Wikipedia.
