Paul Roux de Marcilly, also known as Paul Marsilly, was a central figure in a plot against King Louis XIV of France in 1668. The conspiracy aimed to overthrow the French monarchy and establish republics in provinces like Provence, Dauphiné, and Languedoc, with the support of Switzerland, Spain, and the United Netherlands. Roux de Marcilly was betrayed and illegally kidnapped in Switzerland before being condemned to death by "breaking on the wheel" in Paris in 1669. French novelist Marcel Pagnol suggested that Roux was associated with the famous masked prisoner, known as “The Man in the Iron Mask,” who was believed to be Louis XIV’s twin brother and a legitimate heir to the crown. The plot also allegedly involved King Charles II of England and other prominent figures. Roux's valet, known as Martin, was also implicated in the conspiracy and was later arrested and imprisoned. The events surrounding Roux de Marcilly's involvement in the conspiracy against Louis XIV and the subsequent repercussions have been the subject of historical interest and speculation.
