Drummond was a Jacobite army officer and the son of a Jacobite nobleman. Born in France, he raised the Royal Ecossais under his command in 1743-4. This regiment would be the backbone of France’s contribution to the Jacobite Rising of 1745. After the disastrous Battle of Culloden, Drummond returned to France. He inherited the Jacobite title of fourth duke of Perth after his brother’s death. His promising French army career was cut short when he died of a fever after the siege of Bergen op Zoom in 1747. This portrait is the main surviving image of the duke. It was painted in 1739, when Drummond was a member of the Society of Young Gentlemen Travellers in Rome.
