Like other Non-Jurors, he was deprived of his Church offices and became instead one of the most prominent Jacobite and Tory propagandists; this included a long dispute with his Trinity College contemporary William King, who supported the Revolution.
[2] Much of his early writing focused on Scotland, where the 1690 Settlement ended Episcopacy and restored a Presbyterian kirk; Leslie used this to inspire concern about William's intentions towards the Church of England.
[7] Ironically, his modern fame now rests primarily on a pamphlet written in 1695, called Gallienus Redivivus, or Murther will out, &c. Being a true Account of the De Witting of Glencoe, Gaffney.
Despite his Tory allies now being in government, a warrant was issued for Leslie's arrest for his tract The Good Old Cause, or, Lying in Truth;[2] in 1711 he escaped to Paris, where James Francis Edward had succeeded his father as the Stuart heir in 1701.
[13] The Spanish-sponsored 1719 Rising in Scotland was judged to have done more damage to the Jacobite cause than otherwise, one of its leaders concluding "it bid fair to ruin the King's Interest and faithful subjects in these parts".
[15] He returned to Paris in 1717 and in 1719 published a two folio-volume edition of his Theological Works; it was later claimed these placed him "very high in the list of controversial authors, the ingenuity of the arguments being equalled only by the keenest and pertinacity with which they are pursued.
[18] Some of his ideas were employed by 18th-century conservative writers like John Hutchinson; the rise of the Oxford Movement in the early 19th century led to the reprint of his Theological Works in the 1830s, Henry Newman one of those to reference them.
[19] Critics including Samuel Johnson and Thomas Macaulay viewed his style as more memorable than the ideas, while for modern commentators, he was defending a political ideology that bore little relationship to reality.
[21] Instead, Macaulay made the Massacre more widely known while it is also argued Leslie's perspectives continue to shape views of William's reign as particularly disastrous for Scotland, with Glencoe one of a series of incidents like the Darien scheme, the famine of the late 1690s and the 1707 Union.
