Oswald Mosley emerged as a charismatic figure in British politics during the interwar period, leading the fascist movement known as the British Union of Fascists (BUF). Inspired by the success of Mussolini's regime in Italy, Mosley advocated for a corporatist state, a strong leader, and a return to traditional British values. While the BUF initially gained some support among disillusioned ex-servicemen and dissatisfied elements of society, it faced opposition from the government and mainstream political parties. After the outbreak of World War II, Mosley and other BUF leaders were detained, effectively ending the movement's influence in British politics.
