South Korean President Yoon Seok-yol declared martial law in the country on the evening of December 3, sparking unrest.

Yoon Seok-yol later agreed to lift the martial law imposed on the country on the night of December 4.
Representatives of a number of public organizations gathered at Gwanghwamun Square in Seoul to condemn the president's declaration of martial law and demand the government's resignation. The main opposition party in South Korea, the Toburo Democratic Party, announced its intention to impeach South Korean President Yoon Seok-yol. They noted that the president's actions "violate the constitution and democracy."
