The Freemasons history goes way back to the days of the crusaders. Few really know what goes on behind those walls.
Relations with the Illuminati were established at Munich and Freising in 1780.
The Illuminati are movement of freethinkers that were the most radical offshoot of The Enlightenment — whose adherents were given the name Illuminati (but who called themselves "Perfectibilists") — was founded on May 1, 1776 in Ingolstadt in 1830. This group has also been called the Illuminati Order, and the Bavarian Illuminati, and the movement itself has been referred to as Illuminism.
In 1777, Karl Theodor, Elector Palatine, succeeded as ruler of Bavaria. He was a proponent of Enlightened Despotism and in 1784, his government banned all secret societies, including the Illuminati and the Freemasons.
While it was not legally allowed to operate, many influential intellectuals and progressive politicians counted themselves as members, including Ferdinand of Brunswick and the diplomat Xavier von Zwack.[1] Although some Masons were known to be members there is no evidence that it was supported by Freemasons. Indeed, membership in the Illuminati, unlike that in Freemasonry, did not require belief in a Supreme Being. As a result, atheists having only the former organization open to them, congregated disproportionately in it; this over-representation, taken along with the Illuminati's largely humanist and anti-clerical bent, likely accounts for many of the claims of atheism leveled at the alleged world conspiracy of which the Illuminati supposedly remain a part.
The Illuminati's members pledged obedience to their superiors, and were divided into three main classes: the first, known as the Nursery, encompassed the ascending degrees or offices of Preparation, Novice, Minerval and Illuminatus Minor. The second, known as the Masonry, consists of the ascending degrees of Illuminatus Major and Illuminatus dirigens. It was also sometimes called Scotch Knight. The third, designated the Mysteries, was subdivided into the degrees of the Lesser Mysteries and those of the Greater Mysteries. Relations with Masonic lodges were established at Munich and Freising in 1780.
The order had its branches in most countries of the European continent; it reportedly had around 2,000 members over the span of 100 years.
