According to historian Sharman Kadish, The Britons was "the most extreme group disseminating anti-Semitic propaganda in the early 1920s - indeed the first organisation set up in Britain for this express purpose.

[3] Beamish became involved with the Silver Badge Party but by 1919 had left Britain altogether after facing damages for a libellous poster against Sir Alfred Mond and, becoming a vehement anti-Semite, progressing to Nazi propagandist.

These featured contributions from some of the most fanatical and notorious anti-Semites of the time, including Joseph Banister and George Clarke, 1st Baron Sydenham of Combe, as well as translations of work by Nazi race theorist Alfred Rosenberg.

Researcher Nick Toczek claims that for the sum of £30, The Britons purchased a set of printing plates and the publishing rights to The Jewish Peril: The Protocols of the Learned Elders of Zion from that company.

[citation needed] Short of funding, The Britons was little more than the board of the publishing "house" after Clarke's death in 1931, soon run by solicitor James D. Dell until 1949.

The board launched a new anti-Semitic, far-right publication Free Britain, which featured contributions from Arnold Leese and Colin Jordan,[9] but was largely defunct as a political organization by the 1950s.
