In 1949 the South Korean government created the National Guidance League, enrolling former leftists and, in practice, many people signed up to meet local quotas, in exchange for amnesty and re-education. When North Korea invaded in June 1950, police and military units were ordered to detain and kill League members and prisoners held in southern jails to prevent them assisting the advancing army; among the largest killings were those at Daejeon, where an estimated 3,000-7,000 people were shot over several days in July 1950, photographed by a US Army officer whose images were declassified decades later. Estimates of the total run from 60,000 to 200,000. The killings were officially denied for half a century, and public discussion was punishable; an Associated Press investigation and the opening of US archives in the late 1990s reopened the subject. South Korea's Truth and Reconciliation Commission, established in 2005, confirmed a large number of incidents, recommended a state apology and compensation, and President Roh Moo-hyun apologised for several specific massacres. North Korean forces also killed detainees and suspected collaborators during their occupation and retreat, and both sets of killings are documented in the commission's reports.

The South Korean government claimed roughly 300,000 enrolled members by 1950, though enrolment quotas meant many were signed up without political affiliation of any kind. South Korea's Truth and Reconciliation Commission, reporting in 2009, found that the executions extended beyond League members to political prisoners held in ordinary prisons, so the population actually acted on was larger than the League roll.
The range is the one used in the historical literature: the lower figure reflects conservative reconstructions from verified incidents and prison records, the higher figure estimates by historians including Kim Dong-choon working from police organisation and quota documents. South Korea's Truth and Reconciliation Commission verified thousands of individual deaths and treated the full toll as unknowable.
South Korea's Truth and Reconciliation Commission, declassified US military records and survivor testimony documented the round-ups and executions.
