Both Illuminati and Freemasonry are organizations composed of freethinkers and intellectual individuals. They are similar in a way as they both started as secret groups but they have different beliefs and goals. Illuminati members are more of a “leftist” group as it was believed that its goal is to create a New World Order while working behind the scenes, while the Freemasons goal is to promote honor and chivalry among its members. Illuminati are a secret society with vague existence while Freemasons are already known and have been performing charitable works worldwide.
