Historically, the word ILLUMINATI referred to the Bavarian Illuminati, an Enlightenment-era secret society founded on May 1, 1776. Today it is referred to as a purported conspiratorial organization which is alleged to mastermind events and control world affairs through governments and corporations to establish a New World Order. Entities that are under the Illuminati umbrella include the Bilderberg Group, The Council on Foreign Relations, The Tri-Lateral Commission, The Bohemian Grove, among many other groups and news organizations and corporations.
