Communist Party of Korea
The USAMGIK banned strikes on December 8 and outlawed the people's committees on December 12 1945. However, in September 1946 the Communist Party of Korea initiated a General Strike. This started among railway workers in Busan but it spread to other industries by September 24 and more than a quarter of a million workers joined in the strike. The USAMG organised military operations to oppose the strikers and also encouraged right-wing anti-communist groups. On October 1 a strike protest in Daegu was fired on by police and a worker was killed. Demonstrations in the following days developed into the 'Autumn Uprising'. The U.S. administration responded by declaring martial law, firing into crowds of demonstrators and killing a publicly unknown number of people.
