South Korean President Lee Jae Myung vowed "strict accountability" for the perpetrators behind last year's failed

martial law attempt by former leader Yoon Suk Yeol, calling the upheaval a test of the country's democratic resilience.

Speaking in a special address to the nation, Lee described the events of Dec. 3 as a "revolution of light," according to

an English translation by Ariang News, and said that this "revolution" was incomplete.

He added that investigations and trials tied to the insurrection remain underway.

The former president is currently on trial for insurrection, while prosecutors have reportedly sought a 15-year prison

term for former prime minister Han Duck-soo.

Other senior officials, including Yoon's defence minister and the former head of the National Intelligence Service, have

also been arrested in connection with the attempt to impose military rule.

The speech marked one year since Yoon abruptly declared martial law, the first such move in Asia's fourth-largest

economy since 1980.

Lee labeled the martial law attempt by Yoon a "self-coup" and said that "those who destroyed the constitutional order

for personal ambition and even sought to provoke war must face judgment, to build a country where no one can ever again

dream of a coup."

The South Korean president also commended the South Korean people in his speech, saying that they had overcome an

"unprecedented democratic crisis" peacefully, and were "fully deserving of the Nobel Peace Prize."

When asked by the press if he would nominate the South Korean people for the honour, Lee clarified that this was merely

his personal opinion, but hoped that his comment would be a "trigger [for] people's discussions."

Martial law attempt

The crisis began on Dec. 3, 2024, when Yoon suddenly declared martial law in a late-night address and accused Lee's

Democratic Party of Korea of engaging in "anti-state activities" and colluding with "North Korean communists."

Yoon ordered troops to the country's National Assembly, where soldiers blocked access and clashed with protesters and

lawmakers as special forces attempted to enter the chamber.

But within three hours, the martial law order was overturned after 190 of the 300 National Assembly lawmakers —

including Lee — managed to gather in the chamber and unanimously overturned the decree. Yoon eventually lifted martial

law about six hours after his announcement.

South Korea then spiraled into weeks of political turmoil. Yoon was impeached on Dec. 14, making then-Prime Minister Han

the acting president. Han was also impeached on Dec. 27 and replaced by then-Deputy Prime Minister Choi Sang-mok.

The country's Constitutional Court then reinstated Han in March, making him acting president again until the court

finally removed Yoon from office on April 4. Yoon was later arrested and charged with insurrection, an offense that

carries the maximum penalty of death.
