The Duke of Monmouth was a title held by James Scott, the illegitimate son of King Charles II of England. Born in 1649, he became a prominent figure in the late 17th century, known for his attempts to claim the English throne. His most notable action was leading the Monmouth Rebellion in 1685, which aimed to overthrow his uncle, King James II. The rebellion was ultimately unsuccessful, leading to the defeat of Monmouth's forces at the Battle of Sedgemoor. Captured shortly after, he was executed later that year. The Duke's legacy remains significant in discussions of succession and the political turmoil of the time.
