The Australian Communist Party (ACP) was founded in 1920 and aimed to promote the principles of Marxism-Leninism in Australia. It sought to represent the working class and advocate for social and economic reforms, including the nationalization of key industries. The party was influenced by the global communist movement and aligned itself with the policies of the Soviet Union during the Cold War. Throughout its history, the ACP faced internal divisions and external pressures, particularly during the Red Scare of the 1950s. The party's influence waned over the decades, leading to its eventual decline. In 1991, the ACP was officially dissolved, marking the end of its political activities in Australia.
