Martial Law’s Legacy Continues Shaping South Korea’s Political Climate
One year after the short-lived martial law declaration, South Korea still grapples with the hostility it unleashed. The brief decree fundamentally altered political identities and continues influencing how parties engage with one another.
The crisis deepened mistrust among supporters of major parties, embedding a long-lasting sense of conflict. Analysts argue that despite time passing, its unresolved nature keeps polarization active and politically useful.

Social Divides Intensify as Political Conflict Spills Into Daily Life
Researchers highlight the rise of affective polarization, where identity forms around hostility toward opposing political groups. This emotional divide has begun extending beyond policy disagreements into daily relationships and interactions.
Surveys show political conflict surpassing economic or generational issues as South Korea’s most severe social division. As hostility moves into personal spaces, avoidance and social fragmentation become more common across communities.
Partisan Bases Harden While Overall Polarization Shows Nuanced Patterns
Experts note that mass-level polarization may not be strictly worsening across every demographic. However, the divide between committed party bases has notably widened since the martial law incident.
These bases increasingly define their political identity by disliking the opposing side. Evidence shows deepening affective distance, with cross-party favorability scores remaining extremely low among dedicated supporters.

Political Elites Amplify Hostility Through Conflict-Based Messaging
Analysts emphasize that antagonistic rhetoric from political elites is a major driver of affective polarization. Politicians increasingly rely on messaging that energizes supporters through resentment and fear of the opposing bloc.
Social media accelerates these signals, spreading outrage-driven narratives that shape voter perceptions. As digital platforms magnify conflict, emotionally charged political content becomes a dominant feature of public discourse.
Ongoing Legal Battles Ensure That Partisan Hostility Remains Active
The unresolved martial law issue continues fueling adversarial politics between opposing parties. As the administration pursues accountability, conservative groups respond defensively, reinforcing a cycle of mutual escalation.
Experts warn that continued pressure surrounding the crisis ensures hostility remains activated. This political struggle becomes self-sustaining as each side mobilizes its base by framing the issue as existential.
Elections Push Parties Further From Moderation and Toward Extreme Positions
With local elections approaching, both major parties appear to be abandoning centrism in favor of base mobilization. Party leadership structures increasingly empower highly committed members, shifting priorities toward extreme positions.
Scholars note that parties rely heavily on emotional appeals rather than policy-driven communication. This strategy energizes core supporters but further alienates moderates who feel disconnected from political battles.
Long-Term Risks Include Public Apathy and Structural Democratic Weakening
Younger generations show rising political disengagement as polarization becomes exhausting. Polls indicate increasing numbers of young adults express no party preference, signaling weakening political efficacy.
Experts warn that sustained apathy may reduce the moderating influence of centrists, allowing extreme factions greater dominance. Without institutional reforms and renewed trust-building, South Korea risks deeper instability and weakened democratic resilience.
