The History You Never Heard Lecture at Northeastern University
A Walden Korea Public Education Project on Jeju 4·3, State Violence, and Truth-Seeking in the United States
‘The History You Never Heard’ is a long-term Walden Korea project dedicated to informing the American public about the 1948 Jeju 4·3 Uprising and Massacre in South Korea and the realities of state violence. The project includes seminars and academic programs held across the United States, as well as publications that raise awareness of state crimes and the importance of truth, justice, and reconciliation.
The massacre of more than 30,000 civilians on Jeju Island began in April 1948, during the period when South Korea was governed by the United States Army Military Government in Korea (USAMGIK). At that time, the United States exercised operational control over South Korea’s armed forces. Historical records indicate U.S. involvement in suppressing the uprising, yet few Americans are aware of this history. We call on the United States to release additional classified documents and to cooperate with further fact-finding efforts. The truth must be told. Nation-states sometimes commit grave errors, and the United States is no exception. Decisions made by the U.S. in Korea more than 70 years ago still cast a long shadow over the politics of the Korean Peninsula today.

HyungJin Kim is a member of the Walden Korea Planning Committee and a board member of WeHope, a human rights organization dedicated to the victims of Japan’s “comfort women” system. She has worked for years to advance accurate and just narratives in the United States.
HyungJin presented her research on the Jeju 4·3 Uprising and Massacre at the Walden Korea International Strategic Forum, held in September.
