James Douglas, 2nd Duke of Queensberry and 1st Duke of Dover (18 December 1662 – 6 July 1711) was a Scottish nobleman and a leading politician of the late 17th and the early 18th centuries. As Lord High Commissioner he was instrumental in negotiating and passing the Acts of Union 1707 with England, which created the Kingdom of Great Britain.
On the accession of Queen Anne in 1702, Douglas was appointed Secretary of State for Scotland.[2] He encouraged the Jacobites by his undecided attitude on the question of the settlement, and was deluded into unconsciously furthering the Jacobite designs of Simon Fraser, 11th Lord Lovat. Lovat had used Queensberry's jealousy of the duke of Atholl to obtain a commission from him to get evidence in France which would implicate Atholl. The plot was betrayed to Atholl by Robert Ferguson, and Douglas withdrew from government in 1704.[2]
