The Bavarian Illuminati was active in Bavaria at the end of the 18th century. According to some researchers, it then went underground and continue to operate behind the scene to this very day with families such as the Rockefellers and Rothschilds leading the way.
The Illuminati used secret hand signs and grips as the Freemasons continue to do today.
