Far-left politics in the United Kingdom have existed since at least the late 19th century, with the formation of various organisations following ideologies such as revolutionary socialism, anarchism and syndicalism. Following the 1917 Russian Revolution and developments in international Marxism, new organisations advocated ideologies such as Marxist-Leninism, Left Communism and Trotskyism. Following the 1949 Chinese Revolution, further international developments from the 1960s led to the emergence of Maoist groups. Political schisms within these tendencies created a large number of new political organisations, particularly from the 1960s to the 1990s.
