James Scott (born James Fitzroy) was an illegitimate son of King Charles II of England. When his father died, James Scott tried to become king by leading a rebellion against his uncle who was now King James II. As an illegitimate son, he had very little right to claim the throne but hoped to gain support of his fellow Protestants as King James II was Catholic. His tiny war became known as the Monmouth Rebellion (referring to his title as Duke of Monmouth) which started in May and ended a little later in July of 1685. King James II crushed his rebellion and had his nephew executed for treason.
