The Illuminatus! Trilogy is a series of three novels by American writers Robert Shea and Robert Anton Wilson, first published in 1975. The trilogy is a satirical, postmodern, science fiction–influenced adventure story; a drug-, sex-, and magic-laden trek through a number of conspiracy theories, both historical and imaginary, related to the authors' version of the Illuminati. The narrative often switches between third- and first-person perspectives in a nonlinear narrative. It is thematically dense, covering topics like counterculture, numerology, and Discordianism.
