ARCHIBALD CAMPBELL, 5th earl of Argyll (153o-73), was the elder son of Archibald, 4th earl of Argyll (d. 1558), and a grandson of Colin, the 3rd earl (d. 153o). His great-grandfather was the 2nd earl, Archibald, who was killed at Flodden in 1513, and whose father was Colin, Lord Campbell (d. 1493), founder of the greatness of the Campbell family, created earl of Argyll in 1457. With Lord James Stuart, afterwards the regent Murray, the 5th earl of Argyll became an adherent of John Knox about 1556. As one of the "lords of the congregation" he was one of James Stuart's principal lieutenants during the warfare between the reformers and the regent, Mary of Lorraine ; later he was separated from Knox's party by his friendship with Mary, Queen of Scots. Though he disapproved of her marriage with Darnley he took her part after Elizabeth's refusal to help Murray in 1565. Argyll was probably an accomplice in the murder of Rizzio; he was certainly a consenting party to that of Darnley; then separat ing from Murray he commanded Mary's soldiers after her escape from Lochleven. Soon afterwards he made his peace with Mur ray, but it is possible that he was accessory to the regent's murder in 1570. In 1572 Argyll became lord high chancellor of Scotland, and he died Sept. 12 1J73. His first wife was an illegitimate daughter of James V., and he was thus half-brother-in-law to Mary and to Murray.
