Yoon Suk Yeol

Yoon Suk Yeol (born 18 December 1960) is a South Korean politician and former prosecutor who served as the 13th president of South Korea from 2022 until he was removed from office in 2025. The shortest-serving directly elected president of South Korea in its democratic history, Yoon previously served as the prosecutor general of South Korea from 2019 to 2021.

Born in Seoul, Yoon received his bachelor's and master's degrees in law from Seoul National University. In his capacity as chief of the Seoul Central District Prosecutor's Office, he played a key role in convicting former presidents Park Geun-hye and Lee Myung-bak for abuse of power. In 2019, President Moon Jae-in appointed Yoon as Prosecutor General of South Korea. Under Yoon's leadership, the Supreme Prosecutor's Office conducted embattled investigations into Cho Kuk, an influential figure in the Moon administration, that led to Cho's resignation as Minister of Justice. Yoon's clashes with the Moon administration prior to his resignation as prosecutor general in 2021 led to his rise as a potential presidential candidate among conservative voters.

In June 2021, Yoon announced his candidacy in the 2022 presidential election. He joined the People Power Party (PPP) in July and won its nomination in November. Considered a conservative and economically liberal politician, Yoon ran on a platform promising economic deregulation and measures such as abolishing the Ministry of Gender Equality and Family. He narrowly defeated Democratic Party nominee Lee Jae-myung by less than a percentage point on 9 March 2022 and assumed office as president on 10 May, becoming the first elected president to be born after the end to fighting in the Korean War. During his presidency, Yoon's foreign policy has been described as both more hawkish toward North Korea and friendlier to Japan compared to previous South Korean presidents. His handling of the Seoul Halloween crowd crush in 2022 and the ongoing medical crisis has attracted criticism. In the 2024 parliamentary midterm elections, Yoon's party suffered a defeat, which weakened his political power. Under Yoon's tenure, South Korea underwent democratic backsliding and a shift towards authoritarianism. He received mostly low approval ratings as president and had been described as a lame duck.

On 3 December 2024, Yoon declared martial law, the first time it had been declared in South Korea since the military dictatorship of Chun Doo-hwan in 1980. He accused members of the National Assembly of supporting North Korea, but lifted martial law after the Assembly passed an emergency motion nullifying the declaration a few hours later. Amid widespread criticism and mass protests, an impeachment motion was introduced against Yoon the next day, though it fell short of the 200 votes needed to pass.

Yoon was successfully impeached and suspended from his presidential powers in a second vote ten days later, with 204 voting in favor, including 12 members of his own party. Yoon subsequently became the first sitting president in South Korean history to face an arrest warrant and, in January 2025, the first to be arrested and incarcerated. During his impeachment trial, it was revealed that Yoon had been planning the martial law declaration alongside Minister of National Defense Kim Yong-hyun for several months. On 4 April, the Constitutional Court unanimously upheld Yoon's impeachment by the National Assembly, officially terminating his presidency. Yoon announced his departure from the PPP in May. Yoon is currently being investigated for heading an insurrection, and may face either life imprisonment or the death penalty if convicted.
