John Birch SocietyRobert Welch introduced the idea of the John Birch Society at an Indianapolis meeting he convened on December 9, 1958 of 12 "patriotic and public-spirited" men.
The first chapter was founded a few months later in February 1959.
The core thesis of the society was contained Welch's initial Indianapolis presentation, transcribed almost verbatim in The Blue Book of the John Birch Society, and subsequently given to each new member.
According to Welch, both the US and Soviet governments are controlled by the same furtive conspiratorial cabal of internationalists, greedy bankers, and corrupt politicians.
If left unexposed, the traitors inside the US government would betray the country's sovereignty to the United Nations for a collectivist new world order managed by a "one-world socialist government."
The Birch Society incorporated many themes from pre-WWII rightist groups opposed to the New Deal, and had its base in the business nationalist sector discussed earlier.
