Sentinels of the Republic
The Sentinels of the Republic was a 1922 to 1944 American organization that opposed what it saw as federal encroachment on the rights of the States and of the individual. Possibly influenced by early forms of libertarianism, it opposed various forms of governmental interventions, including child labor legislation. The organization was heavily supported by some of the country's wealthiest capitalists and industrialists.
The organization also opposed Communism. There were accusations of anti-Semitism, possibly for reasons such as comments by some members related to the relationship between Jews and Communism. The organization's accused leader Alexander Lincoln later denounced all forms of autocratic government, "whether they be communism, bolshevism, fascism, or Hitlerism." The commander-in-chief of the Jewish War Veterans wrote to Lincoln that, following its own investigation, his organization had concluded that Lincoln did not "entertain any antipathy against the Jewish people or any racial minority. Regardless, leftist Wikipedia categorizes the organization as belonging to "Far-right politics in the United States".
