William Douglas, 1st Duke of Queensberry

He succeeded his father as Earl of Queensberry in 1671 and took his seat in the Parliament of Scotland on 12 June 1672.

He refused to support James VII's measures against the established church in 1685.

From 1685 he was one of the lords of the Privy Council for both Scotland and England, but in 1687 he was accused of maladministration by James Drummond, 4th Earl of Perth and was stripped of his appointments.

He assented to the accession of William and Mary and again enjoyed the royal favour before he died, being appointed Extraordinary Lord of Session in 1693.
