Robert Ferguson

Robert Ferguson (born c. 1637, Aberdeenshire, Scot.—died 1714, London, Eng.) was a Scottish conspirator and pamphleteer known as “the Plotter,” who gave indiscriminate support to the opponents of Charles II and James II and then to the Jacobites against William III.

Educated for the Presbyterian ministry, Ferguson went to England in the 1650s and received the living of Godmersham, Kent, only to be ejected in 1662. As a Protestant dissenter of known literary ability, he was later taken up by Anthony Ashley Cooper, 1st earl of Shaftesbury, and published in 1680 two notorious pamphlets purporting to demonstrate the legitimacy of James, duke of Monmouth, Charles II’s illegitimate son. In the next two years he published at least six more exclusionist pamphlets and claimed the authorship of many more. He fled to the Netherlands with Shaftesbury in 1682, and he was outlawed after the discovery of the Rye House Plot (1683).

Ferguson was one of Monmouth’s right-hand men in the rising of 1685, but he enjoyed a less prominent position in William III’s expedition in 1688. Whether out of resentment or simply a chronic itch for conspiracy, he now became an active Jacobite, and in his last notable work, The History of the Revolution (1706), he argued that this event was a Roman Catholic plot. Both sides, however, regarded him with understandable suspicion, and he died in deep poverty in London.
