South Korea is grappling with a deep political crisis following President Yoon Suk Yeol’s sudden declaration of martial law on the evening of December 3, 2024. The move, widely perceived as an attempt to quell political opposition rather than address any imminent threat, was short-lived but has left the nation in turmoil, with opposition parties now pushing for the president’s impeachment.
Yoon’s late-night announcement cited vague threats from “anti-state forces” and alleged sympathies with North Korea within the political opposition. The declaration granted the military sweeping powers, including control over media, prohibitions on political activities, and suspension of parliamentary functions. Armed troops, accompanied by helicopters, surrounded the National Assembly, creating scenes reminiscent of South Korea’s authoritarian past. By early morning on December 4, parliament—despite being physically blocked—managed to convene and vote unanimously to annul the martial law decree, prompting Yoon to rescind it.
The backlash has been immediate and intense. Opposition lawmakers, led by the Democratic Party, have labeled Yoon’s actions unconstitutional and an act of rebellion against the democratic process. On December 4, they submitted a motion to impeach the president, which is expected to be voted on later this week. Impeachment would require the support of two-thirds of the National Assembly and confirmation by at least six of the nine justices in the Constitutional Court. Given the Democratic Party’s majority and the inclusion of several opposition-aligned justices in the court, the path to impeachment appears plausible.
Yoon’s declaration of martial law is the first such move in South Korea since 1980, evoking painful memories of past authoritarian regimes. Martial law was a tool frequently used during the country’s decades of military-backed governments to suppress dissent and consolidate power. However, since South Korea’s democratic transition in the late 1980s, such measures have been considered relics of a bygone era. Yoon’s actions, therefore, have been met with widespread condemnation both domestically and internationally.
Protesters quickly gathered outside the National Assembly as news of the martial law declaration spread, chanting slogans denouncing dictatorship and demanding Yoon’s resignation. Inside the parliament, lawmakers resorted to climbing fences and dodging barricades to cast their votes. Despite the tense standoff, no violence was reported, and the military withdrew shortly after the annulment of the decree.
Observers have pointed to Yoon’s declining popularity and mounting political challenges as potential motivations behind his drastic move. Since taking office in 2022, Yoon has faced criticism for his confrontational style, allegations of corruption involving his administration and family, and policy missteps. His approval ratings have hovered around 20%, and his People Power Party lost its parliamentary majority in April. The opposition has increasingly used its legislative power to block Yoon’s initiatives, further frustrating his administration. Just days before the martial law declaration, opposition lawmakers slashed billions from Yoon’s proposed budget and introduced motions to impeach senior government officials, including the defense minister.
The fallout from Yoon’s decision has been swift. Civic groups, labor unions, and ordinary citizens have held candlelight vigils across Seoul, calling for his resignation. Critics have likened the move to an attempted coup, accusing Yoon of overstepping constitutional boundaries to maintain power. Even members of Yoon’s conservative party have distanced themselves, with some voting alongside the opposition to nullify the martial law order. Seoul’s mayor and the leader of the People Power Party have publicly criticized the president’s actions.
International reactions have also been sharp. The United States, South Korea’s key ally, expressed concern over the sudden declaration of martial law. Secretary of State Antony Blinken stated that Washington had received no prior notice and urged South Korean leaders to resolve their differences through peaceful, democratic means. Neighboring countries like China and Russia have also voiced their interest in the unfolding crisis, with China framing the situation as an internal matter and Russia expressing concern over its impact on regional stability.
Yoon defended his actions as necessary to safeguard the nation’s democratic order, claiming that the opposition posed a threat to national security. However, his justification has been widely dismissed as a political miscalculation. Legal experts have highlighted that the constitution requires specific, verifiable threats for martial law to be declared, and many argue that such conditions were not met.
If the impeachment motion succeeds, Prime Minister Han Duck-soo will assume interim leadership until a new election is held within 60 days. Han has already called for calm and urged government officials to continue fulfilling their duties amid the uncertainty. The Constitutional Court, which will ultimately decide Yoon’s fate, has previously demonstrated its willingness to remove presidents from office. In 2017, then-President Park Geun-hye was impeached over corruption charges, and her removal was upheld by the court.
For many South Koreans, Yoon’s actions are a stark reminder of the fragility of democracy, even in nations that have made significant strides in governance and human rights. The events of this week have drawn comparisons to the tumultuous years of the 1980s, when martial law and violent crackdowns were used to suppress pro-democracy movements. The current crisis has reignited debates about the balance of power, the role of the military in civilian governance, and the importance of safeguarding democratic institutions.
As South Korea navigates this political upheaval, the global community is watching closely. The country has long been a beacon of democracy and economic progress in a region marked by authoritarian regimes. How it resolves this crisis will not only shape its domestic political landscape but also influence its standing on the international stage. For now, the focus remains on the impeachment process and the broader implications of Yoon’s controversial decision.
