Proofs of a Conspiracy by John Robison, published in 1797, explores the idea of a secretive Illuminati organization working to undermine governments and religions across Europe. Robison, a Scottish scientist, argues that the Illuminati infiltrated Freemasonry and other societies to spread revolutionary ideas, which he believed contributed to the French Revolution. The book reflects the fears of the time regarding secret societies and their potential influence on political and social upheaval.
