On December 3 2024 at approximately 22:30 KST, South Korean President Yoon Suk-yeol declared martial law in a live televised address, citing "anti-state forces" and North Korean infiltration of the National Assembly. The National Assembly convened an emergency session and voted unanimously to lift the declaration approximately six hours later; troops that had been deployed to the Assembly were withdrawn. Yoon was impeached by the National Assembly on December 14 2024, arrested on January 15 2025 by the Corruption Investigation Office for High-ranking Officials, and subsequently convicted of insurrection by a court. The conspiracy element — Yoon's framing that opposition lawmakers were North Korean-linked anti-state agents — was the justification for the declaration and was not supported by public evidence.
