George Keith, 10th Earl Marischal

George Keith, 10th Earl Marischal (1692/1693 – 1778) was a Scottish-born army officer and diplomat. After leading Jacobite forces in the failed Jacobite rising of 1719, he fled Britain and joined the Prussian Army. Becoming a close confidant of Frederick the Great, he served as the Prussian ambassador to Spain, France and Great Britain. Keith was the tenth and last Earl Marischal.

Life

George Keith was born in either 1692 or 1693, probably at Inverugie Castle, Aberdeenshire. He was the son of William Keith, 9th Earl Marischal and Mary Drummond, daughter of James Drummond, 4th Earl of Perth. Keith was commissioned into the British Army and served in Flanders during the War of the Spanish Succession from 1708 to 1711, when he left the Army due to his support for placing James Francis Stuart on the British throne after Queen Anne's death. Keith inherited his father's title of Earl Marischal upon the latter's death in 1712. He fought on the Jacobite side during the Jacobite rising of 1715, including at the Battle of Sheriffmuir, and was subsequently attainted for treason by the British government, with his estates being seized by the Crown.

Keith fled to France and went on to serve the Jacobite court at Avignon, including as its ambassador to Spain. In 1719, he invaded Scotland at the head of a force of Jacobite exiles and Spanish marines in the Jacobite rising of 1719, but fled back to the Continent following his defeat at at Glen Shiel. On 29 December 1725, Keith was made a knight of the Order of the Thistle by Stuart. In March 1740, Stuart appointed him to be his commander-in-chief in Scotland, although the position was purely titular and had no practical role. Keith retired from the Jacobite court in 1741 as he found it unable to help the Jacobite cause; Keith warned Stuart not to trust positive reports from his agent in Paris, Francis Sempill.

Becoming increasingly isolated from the many Jacobite plots of the early 1740s, Keith was commissioned into the Prussian Army. In August 1751, Frederick the Great appointed Keith as the Prussian ambassador to France. As he had always been distrustful of Charles Edward Stuart, Keith refused to meet him in Paris during Stuart's secret visits, only engaging with his agent, Henry Goring. Following Stuart's dismissal of Goring in 1751, Keith broke off all communication with him.
