The Monmouth Rebellion (Also known as the Pitchfork Rebellion, Revolt of the West or West Country rebellion) in June 1685 was an attempt to depose James II, who in February had succeeded his brother Charles II as king of England, Scotland and Ireland. Dissident Protestants led by James Scott, 1st Duke of Monmouth, eldest illegitimate son of Charles II, opposed James largely due to his Catholicism.
The failure of Parliamentary efforts to exclude James from the succession in 1681 resulted in the 1683 Rye House Plot, an alleged attempt to assassinate Charles II and James. Monmouth, implicated as a co-conspirator, went into exile in the Dutch Republic. He returned to England when on 11 June 1685, he landed at Lyme Regis in the South West where he had widespread popular support, planning to take control of the area and march on London.
