  • "Order of the Illuminati, a celebrated secret society founded by Professor Adam Weishaupt at Ingolstadt in Bavaria in 1776, originally called the Society of the Perfectibilists. It was deistic and republican in principle, aimed at general enlightenment and emancipation from superstition and tyranny, had an elaborate organization, was to some extent associated with freemasonry, and spread widely through Europe, though the Illuminati were never very numerous. The order excited much antagonism, and was suppressed in Bavaria in 1785, but lingered for some time elsewhere."
