Archibald Douglas, 6th Earl of Angus (c. 1489 – 22 January 1557) was a Scottish nobleman active during the reigns of James V and Mary, Queen of Scots.

The regent took the government into his own hands, Angus was charged with high treason in December and in March 1522 was sent practically a prisoner to France, whence he succeeded in escaping to London in 1524.

Angus was made a Lord of the Articles, was included in the Council of regency, bore the king's crown on the opening of the session, and with Archbishop Beaton held the chief power.

[3] In July 1526 the guardianship of the King James V was entrusted to him for a fixed period till 1 November, but he refused at its close to retire, and advancing to Linlithgow put to flight Margaret and his opponents.

[1] He now with his followers engrossed all the power, succeeded in gaining over some of his antagonists, including Arran and the Hamiltons, and filled the public offices with Douglases, he himself becoming Chancellor.

Angus defeated John Stewart, 3rd Earl of Lennox, who had advanced towards Edinburgh with 10,000 men in August at the Battle of Linlithgow Bridge, and he subsequently took Stirling.

[1] On 11 March 1528, Margaret succeeded in obtaining her divorce from Angus, and about the end of the month she and her lover, Henry Stewart, were besieged at Stirling.

Repeated attempts by James to subdue the fortress by siege failed, and on one occasion Angus's men captured the royal artillery.

George's life and lands were also declared forfeit, as were those of his uncle, Archibald Douglas of Kilspindie (died 1535), known by the nickname of Greysteil, who had been a friend of King James.

Angus's third sister Janet, Lady Glamis, was summoned to answer a charge of communicating with her brothers, and when she failed to appear, her estates were forfeited.

Angus remained in England until 1542, joining in the attacks upon his countrymen on the border, while James refused all demands from Henry VIII for his restoration, and kept firm to his policy of suppressing the Douglas faction.

On James V's death in 1542, Angus returned to Scotland, with instructions from Henry to negotiate a marriage between Mary, Queen of Scots, and Edward VI.

Angus made a bond with Arran and others to maintain their allegiance to Mary, and gave his support to the mission sent to France to offer the latter's hand to the Dauphin.

[9] He still corresponded with Henry VIII, but nevertheless signed in 1546 the act cancelling the marriage and peace treaty, and on 10 September 1547 commanded the van in the great defeat of Scotland at Pinkie, when he again won fame.

His son-in-law, the Earl of Lennox, and the English border warden Thomas Wharton marched from Dumfries to intercept Angus at Drumlanrig Castle.

[13] Under the regency of queen Mary of Guise his restless and ambitious character and the number of his retainers gave cause for frequent alarms to the government.
