The Nordic League was a far right organisation in the United Kingdom from 1935 to 1939 that sought to serve as a co-ordinating body for the various extremist movements whilst also seeking to promote Nazism. The League was a private organisation that did not organise any public events.
The Nordic League (NL) originated in 1935 when agents of Alfred Rosenberg's Nordische Gesellschaft arrived in Britain to establish a UK version of their movement. The main force behind this new group was Unionist MP Archibald Maule Ramsay who chaired the group's 14-man leadership council. The group's constitution described it as an "association of race conscious Britons" and sought to co-ordinate all far-right and fascist movements whilst giving particular emphasis to anti-Semitism.
The League sought to unite leading figures from across the far right, as demonstrated in April 1939 when a meeting addressed by Ramsay was chaired by a member of the British Union of Fascists who was supported by former British Fascists president R. B. D. Blakeney and Imperial Fascist League member E. H. Cole. Other leading members included J. F. C. Fuller, the United Empire Fascist Party leader and Nazi agent Serocold Skeels, Henry Hamilton Beamish, Arnold Leese and P. J. Ridout. The latter was credited with helping to popularise the NL's slogan "Perish Judah", which was frequently rendered "P.J." in public.
BUF leader Oswald Mosley, fearful of being too closely associated with the League's extremist rhetoric, did not join but he permitted party members to do so which the likes of Fuller, Robert Gordon-Canning and Oliver C. Gilbert did readily. As a result of these links the BUF was able to absorb the National Socialist Workers Party, a small group led by NL member Lieutenant-Colonel Graham Seton-Hutchison.
