Founded by Adam Weishaupt in Bavaria in 1776, the Illuminati have been referred to in popular culture, in books and comics, television and films, and games. A number of novelists, playwrights and composers are alleged to have been Illuminati members and to have reflected this in their work. Early conspiracy theories surrounding the Illuminati have inspired various creative works, and continue to do so.
