British fascism is the form of fascism which is promoted by some political parties and movements in the United Kingdom. It is based on British ultranationalism and imperialism and had aspects of Italian fascism and Nazism both before and after World War II. Historical examples of fascist movements in Britain include the British Fascists (1923–1934), the British National Fascists (1924–1928), the Imperial Fascist League (1929–1939), the British Union of Fascists (1932–1940), the British League of Ex-Servicemen and Women (1937–1948) and the Union Movement (1948–1978). More recent examples of British fascist groups include the British Movement (1968–1983), the National Front (1967–present), the British National Party (1982–present), Britain First (2011–present), National Action (2013–2017), and the Sonnenkrieg Division (2015–2020). British fascism, like other fascisms, doesn't have a neat "intellectual genealogy"; it developed its ideas from various sources, British and foreign. British fascism acknowledges the inspiration and legacy of Italian fascism and Nazism but it also states that it is not a mere application of a "foreign" ideology, alleging roots within British traditions. Early British fascism, as seen in the British Fascists, initially had "little evidence of fascism in its ideology". It evolved its ideals in response to conservative influences on the domestic scene and the post-war anti-labour movement. From Italian fascism it took inspiration of strong leadership and strong opposition to communism. Later British fascism, as seen in the British Union of Fascists, while inspired by, for example, Italian fascism's ideas on the Corporate State, claimed both its economic and political agenda intend to embody that of Tudor England (1485–1603). It claimed that its advocacy of a centralised national authoritarian state was based upon the Tudor state's hostility to party factions and to self-interested sectional interests, and upon the Tudor goal of national integration through a centralised authoritarian state.
