'The Communist Party of Australia (CPA) existed from 1920 to 1991 and was the largest party to the left of the Australian Labor Party. Forged in the wake of the Bolshevik Revolution in 1917, it was the purveyor of worldwide socialist revolution in its early years, Marxism-Leninism from the 1930s to the 1960s, and a proto-Eurocommunism from the late 1960s onwards. The CPA had only one MP, Fred Paterson in Queensland between 1944 and 1950, but its political and social influence spread far beyond the electoral stage. The party commanded significant influence in the trade unions, and its members were involved in nearly every social movement of the 20th century, including movements surrounding Aboriginal rights, women’s liberation, anti-fascism, green bans, peace and nuclear disarmament. The party also drew in many artists, writers and cultural figures over the years, even if the official communist movement emanating from Moscow often had more prescriptive views on art and literature.'
