Argyll, Archibald Campbell, 9th earl of, 1629?–1685, Scottish nobleman; son of the 8th earl. An ardent and active royalist and a Protestant, he opposed extreme measures against the Covenanters, thereby incurring the enmity of the duke of York (later James II), who in 1680 was high commissioner of Scotland. Argyll was accused of treason and sentenced to death in 1681. He escaped to Holland, was a leader of the rebellion in favor of the duke of Monmouth, and was captured and beheaded.
