Archibald Douglas was educated at the University of St Andrews and was tutored at Regent Morton's court by John Provan. In 1580 Angus gave a strong support to Morton during the attack upon the latter, made a vain attempt to rescue him, and was declared guilty of high treason on 2 June 1581. He then entered into correspondence with the English government for an invasion of Scotland to rescue Morton, and on the latter's execution in June went in exile to London, where he was welcomed by Queen Elizabeth. After the Raid of Ruthven in 1582 Angus returned to Scotland and was reconciled to KingJames, but soon afterwards the king shook off the control of the Earls of Mar and Gowrie, and Angus was again banished from Court. In 1584 he joined the rebellion of Mar and Glamis, but the movement failed, and the insurgents fled to Berwick-upon-Tweed. Later they took up residence at Newcastle-upon-Tyne, which became a centre of Presbyterianism and of projects against the Scottish government, encouraged by Elizabeth, who regarded the banished lords as friends of the English and antagonists of the French interest. In February 1585 they came to London, and cleared themselves of the accusation of plotting against James's life. A plan was then prepared for their restoration and for the overthrow of James Stewart, Earl of Arran. In October they invaded Scotland and gained an easy victory over Arran, captured Stirling Castle with the King in November, and secured from him the restoration of their estates, and the control of the government. In January 1586 he was granted the Earldom of Morton with the lands entailed upon him by his uncle; this made him 5th Earl of Morton. In November 1586 Angus was appointed Warden of the Marches and Lieutenant-General on the Border, with a force of 100 horsemen and 100 foot soldiers, and their officers, drummers and pipers, and "furriers" or quartermasters. He performed good services in restoring order; but he was unable to overcome the king's hostility to the establishment of Presbyterian government.
Death
in July 1588 it was reported that he had travelled from the west of Scotland "sick of the flux and burning ague." He died on 4 August 1588 at Smeaton, near Dalkeith Palace. He was buried at Aberdour in Fife. As reported in the Newes from Scotland tract of 1591 his death was said to have been caused by witchcraft. His physician found his illness strange and there was no cure or remedy causing him to languish until his death. During the North Berwick witch trials, Gilles Duncan accused Barbara Napier of causing his death by witchcraft. Euphame MacCalzean, Agnes Sampson, and Richard Grierson were also accused. The Earl of Bothwell admitted that he had sent the cunning man Richie Graham to attend the earl.
Family
The Earl of Angus was married three times: on 13 June 1573 at the Church of the Holy Rude, Mary Erskine, a daughter of the Earl of Mar and Annabell Murray. Her "tocher" or dowry was 8,000 merks; 25 December 1575 Margaret, a daughter of George Leslie, 4th Earl of Rothes; 29 July 1587 Jean Lyon, a daughter of John Lyon, 8th Lord Glamis, with whom he had a daughter Margaret, who died unmarried aged 15. Angus began proceedings to divorce Margaret Leslie in August 1586, which were strongly opposed by the Earl of Rothes who considered he had been Angus's ally during his banishment. A French diplomat in Edinburgh, Camille de Preau, sieur de Courcelles, heard that Angus claimed she had flirted with a stableboy, which was thought unlikely, and the Earl of Bothwell had joked he would divorce his wife for the same. She was Angus's sister. He was succeeded in the Earldom of Angus by his cousin William, a descendant of the 5th earl. A closer line of the Douglas family to the former Earls of Morton inherited the Earldom of Morton. For the Morton title, see James Douglas, 4th Earl of Morton and William Douglas, 6th Earl of Morton.
