In 1958 the John Birch Society, an American ultraconservative political advocacy group was founded by retired candy manufacturer Robert Welch to promote anti-communism and social conservatism. At its height, the John Birch Society claimed 100,000 members.
Welch published the Society’s monthly magazine American Opinion and weekly The Review of the News. He also wrote books entitled The Road to Salesmanship, May God Forgive Us, The Politician (Eisenhower) and The Life of John Birch.
An adherent of conspiracy theories, Welch believed many individuals and organizations were part of an international communist plot. Welch accused Presidents Truman and Eisenhower of being communist sympathizers and possibly Soviet agents.
In the 1960s, Welch became convinced that even the Communist movement was a tool of a total conspiracy run by international families of financiers.
