Former leader sentenced for orchestrating insurrection
Seoul's courts handed Yoon Suk Yeol a life term on Thursday for attempting to impose martial law in December 2024, a move that triggered mass protests and his swift impeachment.
Martial law declaration sparks immediate backlash
Yoon announced the emergency decree shortly after 22:00 on 3 December 2024, accusing unnamed "anti-state forces" of infiltrating the country. Within hours, he banned political gatherings and ordered the military to censor media outlets.
By midnight, thousands of citizens had gathered outside the National Assembly in central Seoul, defying the decree. Police formed barricades as protesters scaled fences and lawmakers rushed to convene an emergency session.
"I am a Yoon voter... But he really crossed the line. I regret voting for him."

At 01:00, legislators unanimously voted down the martial law attempt. Yoon rescinded the decree three hours later.
From impeachment to life imprisonment
Public outrage led to Yoon's impeachment on 14 December. After barricading himself in the presidential residence for 17 days, he was arrested on 3 January. Prosecutors sought the death penalty, but the court imposed a life sentence, noting South Korea's moratorium on executions since 1997.
Generational divides and historical echoes
Reactions split along age lines. Younger South Koreans searched "martial law" online in confusion, while older citizens recalled the military dictatorships of Park Chung Hee and Chun Doo Hwan, who used similar tactics to suppress dissent.
Yoon's claim that opponents were colluding with North Korea mirrored Cold War-era purges, reigniting fears of authoritarian resurgence.
Democracy's resilience on display
Stanford University's Gi-Wook Shin called the episode "a rare example of democratic resilience," crediting citizens, lawmakers, and courts for thwarting the coup. Six months later, voters ousted Yoon's party in a landslide, electing opposition leader Lee Jae Myung.
"South Korea has one of the strongest traditions of democratic protest in the world."

Polarization persists despite verdict
While 73% of South Koreans accept the guilty verdict, 27%-primarily Yoon's supporters-reject it. Some allege the ruling Democratic Party is pro-China, echoing right-wing conspiracy theories.
Yoon faces additional trials for corruption and abuse of power. His allies are pushing for a pardon, but the ruling party is drafting legislation to block it.
Global implications
Analysts say the case offers a blueprint for resisting democratic erosion. "Institutions can constrain authoritarian ambitions when citizens and officials act decisively," Shin noted.
An elderly protester told the BBC, "It was a terrifying time. It cannot happen here again."
