The British Union of Fascists (BUF) was a political party in the United Kingdom founded in 1932 by Sir Oswald Mosley. It aimed to promote fascist ideology, emphasizing nationalism and anti-communism. The BUF gained some popularity in the 1930s, particularly during economic turmoil, but faced significant opposition from various groups. The BUF organized rallies and published propaganda to spread its message. However, its influence declined after World War II, especially due to its association with Nazi Germany. The party was officially disbanded in 1940, and its legacy remains controversial in British history.
