The Communist Party of Great Britain (CPGB) was the largest communist organisation in Britain and was founded in 1920 through a merger of several smaller Marxist groups. Many miners joined the CPGB in the 1926 general strike. In 1930, the CPGB founded the Daily Worker (renamed the Morning Star in 1966). In 1936, members of the party were present at the Battle of Cable Street, helping organise resistance against the British Union of Fascists. In the Spanish Civil War the CPGB worked with the USSR to create the British Battalion of the International Brigades, which party activist Bill Alexander commanded.
