Beneath Jeju Island’s stunning landscapes lies the story of the Jeju 4.3 Uprising (April 3 Incident), a tragic chapter in Korea’s modern history that continues to shape its collective memory.
Jeju 4.3 Incident: Remembering Korea’s Hidden Tragedy
Introduction

The Jeju Massacre (Jeju 4.3 Incident) unfolded between 1948 and 1954, beginning on April 3rd, 1948. What started as resistance to political repression became a brutal suppression campaign that left tens of thousands dead. For decades, the tragedy was silenced — but today, it is recognized as a defining moment in Korea’s struggle for democracy and human rights.
Background & Context
After liberation from Japanese colonial rule in 1945, Korea was divided into North (Soviet-backed) and South (U.S.-backed). Jeju, with its fertile land and strong grassroots movements, leaned toward progressive politics. The newly formed South Korean government under Syngman Rhee viewed Jeju as a threat, labeling many residents as “communist sympathizers.” On April 3, 1948, armed resistance clashed with police, sparking years of violent suppression.
Key Highlights
🔴 The Massacre
Villages were burned, civilians executed, and entire communities displaced. Estimates suggest between 30,000–60,000 people (roughly 10% of Jeju’s population at the time) lost their lives.
⚫ The Aftermath
Survivors lived under decades of stigma and silence. Families could not openly mourn, and even speaking of “4.3” was forbidden until democratization in the 1980s.
🕊 The Cover-Up & Truth-Telling
For over 40 years, official records denied the events. Only in the 1990s did the Korean government begin public investigations. In 2003, a presidential apology acknowledged state responsibility.
🌿 The Legacy
Today, the Jeju 4.3 Peace Park and annual April 3 Memorial Ceremony honor the victims. The tragedy remains a symbol of the importance of human rights, democracy, and reconciliation.
