The Autumn Uprising of 1946 was a series of protests and demonstrations that took place in South Korea against the United States Army Military Government in Korea (USAMGIK). These protests were sparked by the USAMGIK's support of the former Japanese colonial government and their decision to keep former Japanese governors as advisors, as well as their disregard of the well-liked People's Republic of Korea. The protests were also a result of the economic and political turmoil that the country was facing in the aftermath of World War II and the division of the Korean Peninsula. The Autumn Uprising led to a crackdown by the USAMGIK, which resulted in the arrests and imprisonment of many Korean leaders and activists. The Autumn Uprising is considered a significant event in the history of South Korea, as it marked the first large-scale popular resistance against USAMGIK's rule, and was a precursor to the larger political and social movements that emerged in the following years.
