South Korean president declares emergency martial law

South Korean President Yoon Suk Yeol declared emergency martial law late on 3 December 2024, accusing opposition parties of anti-state activity and obstruction. Military authorities announced restrictions on political activity and media, and troops and police moved around the National Assembly.

Lawmakers entered the chamber despite security barriers and voted unanimously among those present to demand that martial law be lifted. South Korea's constitution requires the president to comply when the National Assembly requests termination. Yoon withdrew the declaration after several hours.

The opposition's control of parliament and disputes over budgets and investigations formed the political context. Those conflicts did not themselves establish the extraordinary constitutional conditions necessary for military rule. No evidence of an external attack justified the surprise measure.

The declaration revived memories of authoritarian periods before South Korea's democratic transition. Participation by specific military and police officials later became the subject of investigations; responsibility should follow orders, knowledge and individual conduct rather than institutional membership alone.

The constitutional crisis entry isolates the declaration itself, separate from parliament's reversal, subsequent impeachment and criminal proceedings. It does not call the brief duration harmless: an attempted use of armed authority against democratic institutions can be consequential even when legislative resistance prevents sustained control.
