Drummond joined the 1715 Jacobite uprising against the new Hanoverian dynasty ruling Britain. He commanded the cavalry at the battle of Sherrifmuir. After the defeat, he fled to Paris and died in exile. Drummond is shown here with a young black slave, wearing a metal collar, who gazes up at his master. Although at the time of this portrait, the boy's equal humanity was denied, Medina has painted him with warmth and sympathy whilst the Duke seems stiff and remote.
