South Korea is facing its most significant political crisis in years as the fallout from President Yoon Suk-yeol's Dec. 3 declaration of martial law continues to unfold. Despite its swift repeal just two and a half hours later, the crisis has plunged the country into turmoil, characterized by investigations, public protests and a fractured political landscape.

The crisis has triggered simultaneous investigations by the Special Investigation Team (SIT) and multiple arrests of high-ranking military and police officials. President Yoon faces potential impeachment, with a vote scheduled for Dec. 14. Meanwhile, the ruling People Power Party (PPP) has experienced internal turmoil, including the resignation of its floor leader amid accusations of complicity in the martial law declaration.
