Indiana University Bloomington professor Stephen Andrews taught a class about conspiracy culture in American history. He described how conspiracy theories have changed over time, but often include the involvement of groups such as the Illuminati, Freemasons, and Skull and Bones. He talked about how in the 1950s a prominent aspect of conspiracy theories was the threat of communism, but in later decades a global “New World Order” was a more common feature. This is the first of a two-part seminar hosted by the Gilder Lehrman Institute of American History.
