It has been 122 days since South Korean President Yoon Suk Yeol issued an "emergency martial law" order on December 3, 2024. On the morning of April 4, the Constitutional Court of Korea will issue a ruling on Yoon’s impeachment case. From the National Assembly’s motion to impeach to 11 court hearings and now the final verdict, 111 days have passed—far more than for former Presidents Roh Moo-hyun and Park Geun-hye. Over these four months, the divide between the ruling and opposition parties — and within Korean society — has become increasingly apparent. Whether the Constitutional Court can safeguard the Constitution and public trust has become a major focus of public opinion in South Korea.
"I’ve long believed in the resilience of South Korean democracy, but over the past two or three months, I’ve started to worry. In the face of this current political stalemate, I wonder whether Koreans can still accept decisions that contradict their positions," said Gi-Wook Shin, Professor of Sociology at Stanford University, founding director of the Korea Program, and Director of the Walter H. Shorenstein Asia-Pacific Research Center, in an interview with The Paper. He noted that there are no signs South Korea will escape its current political polarization anytime soon — and that the situation may worsen.
Shin entered Yonsei University’s Sociology Department in the late 1970s. In the early 2000s, he founded the Korea Program at Stanford, focusing on social movements and nationalism. In 2024, he published Korea’s Democracy in Crisis: The Threats of Liberalism, Populism, and Polarization, a book whose concerns — resurgent populism and societal polarization — are now vividly reflected in real life.
On December 3, 2024, Yoon declared a state of emergency and described his political opponents as "anti-state forces." The language he used in his televised emergency address was directly reminiscent of the Cold War era. Meanwhile, during Yoon’s administration, opposition parties submitted a record 29 motions for impeachment. These episodes highlight deep rifts in Korean politics, intensifying the fierce struggle between the left and right across all levels of society.
The roots of South Korea’s political divide trace back to the post-WWII era. Under global pressures, political elites on the Korean peninsula quickly split into left-wing, right-wing, and various centrist groups, each hoping to build the country according to their ideals. After the United States and Soviet Union occupied different parts of the peninsula, a sharp ideological confrontation emerged, and the left and right failed to unite to establish a single nation.
During the military rule in South Korea, U.S.-backed authoritarian strongmen governed the country, laying the groundwork for today’s conservative political parties. Meanwhile, leftist forces were strengthened by decades of street protests. Since democratization in 1987, South Korean politics have swung between the left and the right. Under President Yoon, this shift toward the right has become even more pronounced.
Amid the growing hostility between conservatives and progressives, Yoon’s martial law declaration and subsequent impeachment proceedings have amplified South Korea’s political polarization and left-right conflict. Yoon’s supporters have launched massive demonstrations. Conservative voices have grown louder, with many chanting U.S.-style slogans like “Stop the Steal” in homage to Trump’s MAGA movement. Shin warns that among Asian countries, South Korea may be the only one to experience a phenomenon akin to “Trumpism.” A recent survey by Korea’s Center for Conflict Resolution found that most South Koreans see ideological division as the country’s most pressing social issue.
Conservative Voices Grow Louder, More Extreme
The Paper: From your observations, what changes has this political storm — from emergency martial law to the president’s impeachment — brought to South Korean society?
Gi-Wook Shin: Regarding presidential impeachment, Roh Moo-hyun’s case in 2004 was dismissed by the Constitutional Court, and Park Geun-hye was removed from office in 2017. Both previous cases strictly followed legal procedures with clear rules. But this time, the situation is far more chaotic, with fiercer partisan conflict. In a sense, we’re witnessing a threat to the rule of law.
On the other hand, mass mobilization by both the left and the right is very active, especially the anti-impeachment forces, whose scale and influence are significant. This shows that political polarization has deepened, and social division has worsened — developments that deeply concern me.
The Paper: In this wave of political turmoil, what is the core conflict between conservatives and progressives?
Shin: When martial law was declared, the right tried to assert control over state power and justified their actions with claims that pro-North Korean forces needed to be purged from the country. Their stance clearly supports the South Korea-U.S. alliance. In their protests, you’ll often see both Korean and American flags, as well as images of Trump and Yoon Suk-yeol side by side.
The left, by contrast, believes that this emergency declaration is essentially destroying the democracy that South Koreans fought so hard to achieve. They see the right not just as opponents, but as anti-state and anti-people forces.
Today’s political confrontation in South Korea is filled with resentment and hostility. It has become a kind of “identity politics.” That’s why compromise is so difficult. The two sides no longer see each other as legitimate political rivals, but as “evil forces” or enemies to be defeated at all costs.
The Paper: It’s been over three months since the martial law controversy began. As time passes, conservative voices have grown louder, the ruling People Power Party's approval ratings have rebounded, and anti-impeachment rallies are massive. Are we seeing signs of an expanding conservative base?
Shin: Large-scale protests aren’t new in South Korea. In the past, they were usually led by liberal or progressive groups. In recent years, however, right-wing and conservative forces have increasingly mobilized for protests. This is a new trend. You could already see this during the 2022 presidential election: it was extremely close, with Yoon and Lee Jae-myung separated by less than 1 percent of the vote. Conservatives realized the importance of mobilizing public support to counterbalance the left.
Indeed, conservative voices have grown louder and more extreme. We’re even seeing cases of storming courts and self-immolation. But that doesn’t necessarily mean their numbers are increasing. Overall, South Korea’s population is roughly divided into 30 percent liberals, 30 percent conservatives, and about 40 percent swing voters. Sometimes conservatives use “bluffing” to create the impression of overwhelming influence and suppress progressive mobilization.
The Paper: The far right is now active on the political frontlines, loudly supporting the conservative camp. Some far-right individuals even stormed the court. Right-wing YouTubers have become among Yoon’s most fervent defenders. In this context, will the People Power Party continue shifting further right, or even toward the far right?
Shin: What’s visible now is that the ruling People Power Party has some connection to the far-right forces in the current street protests. Especially in the wake of the martial law declaration and impeachment, the far right has taken the lead in organizing massive demonstrations, mobilizing hundreds of thousands every weekend.
There is latent cooperation between the ruling party and the far right. But now that the impeachment has triggered an early presidential election, the People Power Party must also appeal to a broader base, which means distancing itself from the far right — creating a dilemma.
If the People Power Party continues working with the far right, it may retain its base and ensure right-wing support. But elections are won by swing voters. Distancing from the far right helps avoid being labeled “extreme” and attracts moderates.
Given that the election will happen within 60 days of the impeachment, the ruling party has little time to adjust its campaign strategy. They must quickly decide how to handle their relationship with far-right street forces: should they continue cooperating or distance themselves? This will be a core political challenge in the coming weeks.
South Korea’s Democratic Crisis Reflects a Global Trend
The Paper: At conservative protests, many people carry signs with slogans like “Stop the Steal,” borrowed from Trump supporters. Trump had the “Make America Great Again” movement. Yoon has the Taegeukgi Budae movement (a far-right group of older conservatives, many of them fundamentalist Christians who strongly support Yoon). How do you see Trump’s influence on Korean politics?
Shin: It’s interesting. Among Asian countries, South Korea may be the only one to experience something like “Trumpism.” Two factors are worth noting.
First, there are organizational similarities between the Korean and American contexts. Yoon and Trump supporters share common traits, especially religious ones. That’s not the case in other Asian countries. For example, the Philippines is Catholic, others are predominantly Muslim or Buddhist. South Korea is the only Asian country where fundamentalist Christians have strong political influence. (Editor’s note: According to Yonhap, Korea’s Yoido Full Gospel Church is currently the largest Christian church in the world.) There seems to be a connection or sense of identification between American evangelicals and Korean Christian fundamentalists.
Second, ideologically, Korea’s right resembles America’s right. Their fondness for slogans like “Stop the Steal” reflects their belief in election fraud conspiracies. YouTube’s influence in Korea is possibly stronger than in most of the world, especially among the far right. It has become a vital tool for mobilization and organizing large-scale protests.
The Paper: South Korea’s democratization was closely tied to the U.S. export of democracy. After the Korean War, with U.S. support, South Korea adopted a democratic constitution and a relatively modern political framework. How has foreign influence shaped Korean democracy? Is it connected to the current democratic crisis?
Shin: U.S. influence on Korean democracy is complex. Until the 1980s, the United States supported South Korea’s military dictators like Park Chung-hee and Chun Doo-hwan. Only after 1987 did the United States back democratic development. But ultimately, it was the Korean people who fought for democracy. That’s why so many opposed the martial law declaration on December 3. They don’t want to give up hard-won freedoms. Many made great sacrifices for democracy.
South Korea has been democratic for over 40 years. What we see today may be tense or even extreme, but many places worldwide are also experiencing democratic backsliding. It’s unclear whether the United States is doing any better, especially in the Trump era. Many European countries — France, Italy, Hungary, the Netherlands, Spain — are facing similar crises.
South Korea’s current democratic crisis is part of a global trend. It’s just that the martial law announcement drew special attention. But populism, polarization, and identity politics are global issues.
The Paper: After democratization, South Korea again saw emergency martial law, fierce clashes between the president and law enforcement, and general chaos. Yet parliament quickly revoked the martial law order, the impeachment process followed legal procedure, and there were no bloodshed or full societal collapse. What has maintained this relative order?
Shin: South Korea has experienced many legal and political crises before. Also, civic engagement is very high: many LGBTQ+ and minority groups are highly politically active, perhaps even more than in the United States. That’s part of why political clashes are so intense, but it also shows a deep sense of civic participation.
Korea is a relatively well-governed country, with a strong bureaucratic system. I used to believe strongly in the resilience of Korean democracy, but over the past two or three months, I’ve started to worry. Can people still accept outcomes that contradict their positions?
In 2017, the Constitutional Court upheld Park Geun-hye’s impeachment, and most Koreans accepted it and moved on. But this time, it’s unclear whether Yoon’s supporters will accept a guilty verdict — they’re already challenging the court’s legitimacy. On the other hand, if the impeachment fails, opponents may also refuse to accept the result.
The political turbulence may persist for months, or even years.
How to Heal a Divided Society
The Paper: Beyond left-right ideology, what other messages are South Korean protesters trying to express? Also, Korean pop culture has entered these events: people are playing K-pop music and waving glowsticks. How do you see this unique cultural phenomenon?
Shin: Today, there are many legal disputes and procedural questions between the Constitutional Court, regular courts, the Corruption Investigation Office, prosecutors, and police. Sometimes the legal process is inconsistent or fragmented, which confuses the public and weakens faith in the legal system.
But Koreans have a long history of protest culture. They know how to demonstrate in an orderly way. Protests aren’t always serious or violent, sometimes they feel festive or recreational, with music, dancing, and food stalls. Some elderly people even travel from rural areas to Seoul for a day just to enjoy the atmosphere and social gathering.
Also, Korea is a highly centralized society — everything is concentrated in Seoul, and issues can quickly become national news.
The Paper: This political crisis has deepened Korea’s ideological rifts. A recent survey shows that ideological conflict is now seen as the most urgent social problem, even ahead of gender or wealth inequality. What can be done to prevent further division or begin healing?
Shin: There are no signs that Korea will overcome its political confrontation and polarization anytime soon. The divide may worsen. In the long term, I call for political reform.
Korea should adopt a parliamentary system. The current presidential system is “winner-takes-all,” so even if someone wins by less than 1 percent of the vote, they gain total control. A parliamentary system might encourage more cooperation and compromise. But I don’t think Korea currently has the political atmosphere to make that shift.
The electoral system also needs reform. Right now, each district elects just one representative — sometimes by a single vote — giving them total power.
Civic education is another area for reform. Koreans need to learn how to share and compromise. In Korean, “compromise” often carries a negative connotation. But in a democracy, compromise is essential. No one can get everything they want.
These are long-term reforms and there’s a long road ahead. What truly worries me is that in the next year or two, social division may grow even worse.
