South Korean President Yoon Suk Yeol declared “emergency martial law” on Tuesday, accusing the opposition party of controlling parliament, showing sympathy toward North Korea, and undermining the government through anti-state activities.
South Korea is focused on the security challenges posed by North Korea, which aligns itself with Russia. Pyongyang has sent troops to reinforce Moscow’s troops engaged in conflict with Ukraine’s forces.
Yoon made the announcement during a televised briefing, vowing to “eradicate pro-North Korean forces and protect the constitutional democratic order.”
“To safeguard a liberal South Korea from the threats posed by North Korea’s communist forces and to eliminate anti-state elements… I hereby declare emergency martial law,” Yoon said in a live televised address.
Lee Jae-myung, the head of South Korea’s opposition Democratic Party, has described the proclamation of martial law as unconstitutional.

What is martial law?
Martial law refers to the temporary governance by military authorities during emergencies when civilian authorities are deemed unable to operate effectively.
This usually happens during extreme circumstances such as war, natural disasters, civil unrest, or political instability.
Its enforcement can have significant legal consequences, including the suspension of standard civil rights and the imposition of military law.
How long can martial law last?
Although intended to be a short-term measure, martial law can sometimes persist indefinitely.
Why Has South Korea Declared Martial Law?
President Yoon did not reference any specific threat from the nuclear-armed North, choosing instead to target his domestic political adversaries.
He has faced persistent opposition from the National Assembly controlled by rival parties since his inauguration in May 2022, and described the declaration as essential for upholding the nation’s constitutional order. The move comes just a month after the liberal opposition, supported by the Democratic Party of Korea, accused Yoon of plotting to impose martial law as a strategy to evade impeachment over alleged abuse of power.
When Has South Korea Declared Martial Law Before?
Since the founding of the Republic of Korea on August 15, 1948, martial law has been declared 10 times in response to crises such as the Yeosu-Suncheon rebellion and the Korean War.
In the decades following the 1960s, martial law was frequently invoked amid political turmoil.
