The Illuminati were members of a secret society in Bavaria in the late 18th century. They had a political agenda that included republicanism and abolition of monarchies, which they tried to institute by means of subterfuge, secrecy, and conspiracy, including the infiltration of other organizations. They fancied themselves to be "enlightened" but they had little success and were destroyed within fifteen years of their origin

Paranoid conspiracy theorists (PCTs) believe the Illuminati cabal still exists, either in its original form or as a paradigm for later cabals. Many PCTs believe "that large Jewish banking families have been orchestrating various political revolutions and machinations throughout Europe and America since the late eighteenth century, with the ultimate aim of bringing about a satanic New World Order.
