A flowchart showing the history of the early British fascist movement
A number of fascist movements emerged before the Second World War. Amongst those that were founded were:
The British Fascists, founded in 1923 as the British Fascisti by Rotha Lintorn-Orman, one of the very few women to ever lead an avowedly fascist movement. Initially they had only a limited political platform but supported Italian fascism from 1931 to their demise in 1936.
The National Fascisti, a splinter-group of the BF founded in 1924 that from the outset fully supported the tactics of Benito Mussolini. They fell apart after another group, the British National Fascisti, broke away from them.
The British Union of Fascists, formed in 1932 by Oswald Mosley as a successor to his New Party. The largest British fascist party, it absorbed members from other groups and called on the support of leading figures including members of the House of Lords, Commons, many Knights of the realm, as well as, for a time, the Daily Mail newspaper.
After the Second World War a handful of groups emerged which looked directly to fascism and Nazism for their inspiration. Those who have openly done so (in contrast with parties which merely describe themselves as aligned with nationalism) are:
Britain First, a splinter group formed from the BNP in 2011, which abuses social media engagement techniques to gain an audience who may or may not be aware of its core anti-Muslim, anti-internationalist, anti-free speech ideology.
The British National Party a neo-nazi, racist party. Their leader Nick Griffin has had a criminal conviction for holocaust denial.
