The 2024 Martial Law Declaration and Removal

The defining moment of Yoon's presidency occurred in December 2024 with the declaration of emergency martial law. This move was widely criticized for violating constitutional requirements, including the failure to convene a formal Cabinet meeting and infringing upon the rights of lawmakers and the judiciary.

The declaration led to intense political standoff, calls for resignation, and eventually, impeachment proceedings. The National Assembly moved to lift the martial law, and the subsequent legal and political fallout led to Yoon's removal from office on April 4, 2025.
