ARCHIBALD CAMPBELL, 9th earl of Argyll (162g-85), eldest son of the 8th earl, studied abroad, and returned to Scotland with Prince Charles in 1650. The marquis of Lorne (by which title he was known until his accession to the earldom) fought at Dunbar (Sept. 3 165o), and after the battle of Worcester joined Glencairn in the Highlands. Lorne fell under the displeasure of both parties. He was imprisoned in 1657 for refusing to renounce allegiance to the Stuarts, and he was imprisoned (1 663) after the Restoration for incautious attacks on the Government of Charles II. His staunch Protestantism, his opposition to the repressive measures against the Covenanters and his great terri torial influence made him obnoxious to James, duke of York, when he came to Scotland as high commissioner. He was ac cused of treason, without any real evidence, in 1681, and sentenced to death. He escaped to Holland where he joined the conspiracy to set the duke of Monmouth on the throne. He then led an unsuccessful invasion of Scotland (1685) , was taken prisoner at Inchinnan (June 18) and beheaded (June 2g) by order of James II. on the old charge of 1681. His head was exposed on the west side of the Tolbooth, where his father's and Montrose's had also been exhibited.
