9. They Were Banished
The Illuminati was formed in 1776, in Bavaria, by a German law professor named Adam Weishaupt. However, after eight short years they were banished. A new Duke was put in place; Duke Karl Theodor, who in 1785 decided to ban all secret societies; this was most likely one of the main reasons why the group went underground and never returned (publicly that is). There were secret punishments put in place for people who went against the new law and tried to join any kind of secret society. Maybe this was actually the last of the Illuminati. Maybe this is the proof that they actually do not exist. Or maybe they are just that sneaky.
