Moon Jae-in (Korean: 문재인; Hanja: 文在寅; born 24 January 1953) is a South Korean politician, lawyer, and former human rights activist who served as the 12th President of South Korea from May 2017 to May 2022. Born on the island of Geoje to parents who had fled North Korea during the Korean War, Moon grew up in poverty in Busan before studying law at Kyung Hee University and building a career in human rights law alongside his longtime colleague Roh Moo-hyun. His early activism against South Korea's authoritarian governments, including his imprisonment for protesting the Yushin Constitution, shaped his political identity and commitment to democratic reform. Moon entered formal politics as a key adviser and chief of staff to President Roh Moo-hyun, and later served as a member of the National Assembly representing the Sasang district of Busan from 2012 to 2016. He was the leader of the Democratic Party of Korea from 2015 to 2016. After losing the 2012 presidential election to Park Geun-hye, Moon won the 2017 presidential election following Park's impeachment and removal from office. His presidency was marked by diplomatic engagement with North Korea, economic reform measures, and the management of the COVID-19 pandemic. Following his single term, Moon became the first president since South Korea's democratization in 1987 to transfer power to the opposition. In April 2025, he was indicted on bribery charges by South Korean prosecutors.

Early Life

Moon Jae-in was born on 24 January 1953 in Geoje, an island off the southeastern coast of South Korea. His parents were North Korean refugees who had fled south during the Korean War. They settled in a refugee camp on Geoje before eventually relocating to Busan, South Korea's second-largest city, where Moon spent his formative years.

The Moon family lived in poverty during his childhood in Busan. Despite the difficult economic circumstances of his upbringing, Moon proved to be an exceptional student and excelled academically throughout his schooling. His background as the child of North Korean refugees would later inform his political outlook, particularly his advocacy for inter-Korean dialogue and his support for the Sunshine Policy of engagement with the North.

Moon's early political consciousness was shaped by the authoritarian political environment of South Korea in the 1970s under President Park Chung-hee, who had enacted the Yushin Constitution in 1972, consolidating dictatorial power. As a young man, Moon became involved in the pro-democracy movement that opposed the Yushin system. He organized protests against the constitution, an act of dissent that resulted in his arrest and imprisonment. This experience of incarceration for political activism was a defining moment in Moon's life and cemented his commitment to democratic principles and human rights.

After his release, Moon fulfilled his mandatory military service in the Republic of Korea Army, serving from 1975 to 1978 and attaining the rank of sergeant. During his service, he participated in Operation Paul Bunyan, the 1976 operation in the Joint Security Area of the Korean Demilitarized Zone.

Education

Moon Jae-in studied law at Kyung Hee University in Seoul, one of South Korea's prominent private universities. He passed the Korean bar examination and qualified as a lawyer, a credential that would become the foundation of both his professional legal career and his subsequent entry into politics. His legal education provided the basis for his work in human rights law, which he pursued through the 1980s and into the 1990s as South Korea underwent its transition from authoritarian rule to democracy.

Career

Human Rights Law and Early Activism

After completing his legal education, Moon established himself as a human rights lawyer in Busan. It was during this period that he formed a professional and personal partnership with fellow lawyer Roh Moo-hyun, who would later become the 16th President of South Korea. Together, Moon and Roh worked on cases involving labor rights, civil liberties, and the defense of political dissidents during a period when South Korea was still governed by authoritarian or semi-authoritarian regimes.

Moon's work in human rights law during the 1980s placed him at the center of the broader democratic movement in South Korea. His legal practice focused on defending those who had been persecuted by the state for political activities, and he became known within the legal community for his commitment to civil liberties. This body of work built his reputation as a principled advocate for democracy and justice, credentials that would later prove instrumental in his political career.

Adviser to President Roh Moo-hyun

Moon's long professional association with Roh Moo-hyun led to his involvement in Roh's successful 2002 presidential campaign. Moon served as Roh's campaign manager, helping to organize and direct the effort that resulted in Roh's election as president in December 2002.

Following Roh's inauguration, Moon served in several official capacities within the presidential administration. He was appointed as the senior secretary for civil affairs, a position that placed him at the center of domestic policy and governance. Moon subsequently rose to serve as Chief of Staff to the President, holding the position from March 2007 to February 2008, the final year of Roh's presidency. In this role, Moon was one of the most influential figures in the administration, coordinating policy across government ministries and managing the operations of the presidential office, known as the Blue House (Cheongwadae).

The death of Roh Moo-hyun in May 2009, who took his own life amid a corruption investigation, was a deeply significant event for Moon. The loss of his longtime friend and colleague further galvanized Moon's commitment to public service and influenced his decision to pursue his own political career.

National Assembly and Party Leadership

Moon Jae-in entered electoral politics directly in 2012 when he won a seat in the National Assembly representing the Sasang district of Busan. He served as a member of the National Assembly from 30 May 2012 to 29 May 2016.

In 2015, Moon was elected as the leader of the Democratic Party, serving as party chairman from 9 February 2015 to 27 January 2016. During this period, he worked to consolidate the liberal opposition and position the party as a viable alternative to the ruling conservative Saenuri Party (later renamed the Liberty Korea Party).

2012 Presidential Election

Moon Jae-in ran as the Democratic United Party candidate in the 2012 South Korean presidential election, held on 19 December 2012. His opponent was Park Geun-hye of the Saenuri Party, daughter of the late authoritarian leader Park Chung-hee. The election was closely contested, but Moon ultimately lost to Park, who won with approximately 51.6% of the vote to Moon's 48%. The defeat was a significant setback, but Moon remained active in the Democratic Party and continued to build his political profile in anticipation of future opportunities.

2017 Presidential Election

The political landscape shifted dramatically in late 2016 and early 2017 following the impeachment of President Park Geun-hye. Park was impeached by the National Assembly in December 2016 over a corruption scandal involving her confidante Choi Soon-sil, and the Constitutional Court upheld the impeachment on 10 March 2017, formally removing her from office. A snap presidential election was scheduled for 9 May 2017.

Moon ran again as the Democratic Party of Korea candidate and entered the race as the frontrunner. His campaign platform emphasized anti-corruption measures, economic reform, engagement with North Korea, and the strengthening of democratic institutions. On 9 May 2017, Moon won the election with approximately 41.1% of the vote in a multi-candidate field, defeating Hong Joon-pyo of the Liberty Korea Party and Ahn Cheol-soo of the People's Party. He was inaugurated immediately upon election, as the country had been operating under an acting president, Hwang Kyo-ahn, since Park's removal.

Presidency (2017–2022)

Inter-Korean Diplomacy

Moon Jae-in's presidency was defined in significant part by his diplomatic engagement with North Korea and its leader Kim Jong Un. Moon favored the Sunshine Policy, a framework of peaceful engagement and dialogue with the North that had been pursued by earlier liberal South Korean presidents, including Kim Dae-jung and Roh Moo-hyun.

In 2018, Moon participated in three inter-Korean summits with Kim Jong Un. The first summit took place on 27 April 2018 at Panmunjom in the Korean Demilitarized Zone, marking the first meeting between the leaders of the two Koreas since 2007. Moon became only the third South Korean president to meet with a North Korean counterpart. A second summit followed in May 2018, and a third was held in Pyongyang, the North Korean capital, in September 2018.

The summits produced the Panmunjom Declaration, in which the two leaders committed to working toward the denuclearization of the Korean Peninsula and improving inter-Korean relations. The diplomatic engagement attracted significant international attention and was seen as a potential breakthrough in one of the world's most intractable geopolitical conflicts.

On 30 June 2019, Moon participated in a three-way meeting with Kim Jong Un and United States President Donald Trump at the Demilitarized Zone, a historic event that brought together the leaders of South Korea, North Korea, and the United States at the heavily fortified border. Despite the symbolism of these meetings, substantive progress on denuclearization stalled in subsequent years, and relations between North Korea and the international community remained tense.

Economic Policy

Moon's economic agenda focused on addressing inequality and reforming the structure of the South Korean economy. He pursued reform of the chaebol system — the large family-controlled conglomerates such as Samsung, Hyundai, and LG that dominate the South Korean economy. Moon argued that the concentration of economic power in these conglomerates contributed to inequality and stifled competition.

Among his signature economic measures, Moon raised the national minimum wage by more than 16 percent and reduced the maximum legal workweek from 68 hours to 52 hours, a change intended to improve quality of life for South Korean workers and encourage hiring. These policies were controversial; supporters argued they were necessary to address the exploitation of workers and reduce overwork, while critics contended that the rapid minimum wage increase placed undue burdens on small businesses and could lead to job losses.

COVID-19 Pandemic Response

Moon's handling of the COVID-19 pandemic, which emerged in early 2020, received both domestic and international recognition. South Korea was one of the first countries outside of China to face a major outbreak of the virus, but the government implemented an aggressive response centered on widespread testing, contact tracing, and quarantine measures rather than broad lockdowns.

The approach was credited with keeping the initial infection and death rates comparatively low compared to many other countries, and South Korea's model was studied and emulated by governments around the world. Moon's approval ratings benefited from the pandemic response, and his Democratic Party of Korea won a historic victory in the 2020 South Korean legislative election, securing 180 of 300 seats in the National Assembly — the largest majority for any party since the country's democratization in 1987.

Domestic Challenges and End of Presidency

Despite the legislative election success in 2020, the latter portion of Moon's presidency was marked by rising public discontent over housing affordability, particularly in Seoul, where property prices surged significantly during his tenure. The government's attempts to cool the housing market through regulations on property ownership and lending were perceived by many as ineffective.

Moon was constitutionally limited to a single five-year term. In the 2022 South Korean presidential election, held on 9 March 2022, the Democratic Party candidate Lee Jae-myung narrowly lost to Yoon Suk Yeol of the People Power Party, who had previously served as Moon's own prosecutor general. The defeat made Moon the first president since South Korea's democratization to hand power to the opposition party after serving a single term. Moon left office on 9 May 2022.

Post-Presidency

Following his departure from office, Moon Jae-in retired to his private home in Yangsan, a city near Busan. In November 2025, it was reported that Moon was preparing to launch a YouTube channel featuring weekly book discussions, marking a new phase in his public engagement.

In April 2025, South Korean prosecutors indicted Moon on bribery charges. The indictment alleged that Moon had appointed a former lawmaker to a nonprofit organization in exchange for the hiring of his then son-in-law. Moon denied the charges. The indictment placed Moon among several former South Korean presidents who have faced criminal prosecution after leaving office, a recurring pattern in the country's political history.

Personal Life

Moon Jae-in is married to Kim Jung-sook, who served as First Lady of South Korea during his presidency. The couple has two children.

Moon is known for his interest in animals. After his inauguration in 2017, he adopted a dog from a shelter, which became known as the "first dog" of South Korea. The adoption was seen as a symbolic gesture promoting animal welfare and adoption from shelters.

His family background as the son of North Korean refugees has been a frequently noted aspect of his personal narrative and was often cited during his political campaigns as informing his empathy for divided families and his commitment to inter-Korean reconciliation. Moon has spoken publicly about how the experience of his parents' displacement shaped his worldview and his approach to North-South relations.

Recognition

Moon Jae-in's presidency attracted significant international attention, particularly for his diplomatic efforts regarding North Korea. His role in facilitating the 2018 inter-Korean summits and the subsequent meeting involving U.S. President Donald Trump at the DMZ in 2019 positioned him as a central figure in East Asian diplomacy during that period.

His government's response to the COVID-19 pandemic in 2020 was recognized internationally as a model of effective public health management. South Korea's approach of aggressive testing and contact tracing without imposing the strict lockdowns seen in many other countries drew praise from public health officials and international media.

Domestically, the Democratic Party's landslide victory in the 2020 legislative election was interpreted as a strong endorsement of Moon's pandemic response and broader governance. The party's capture of 180 of 300 National Assembly seats represented the largest legislative majority since democratization.

Moon's economic reforms, including the minimum wage increase and the reduction of the maximum workweek, were noted as significant policy achievements by supporters of labor rights, though they remained subjects of debate among economists and business groups in South Korea.

Legacy

Moon Jae-in's legacy in South Korean politics encompasses several dimensions. As a human rights lawyer who rose to the presidency, his career trajectory reflected the broader arc of South Korea's democratic development from authoritarian rule to a mature democracy. His imprisonment as a young activist and subsequent rise through legal and political ranks paralleled the country's own transformation.

His diplomatic engagement with North Korea represented the most sustained period of inter-Korean dialogue in over a decade. The three summits with Kim Jong Un in 2018 and the trilateral meeting at the DMZ in 2019 were historic events, though the failure to achieve concrete progress on denuclearization tempered assessments of their long-term significance. The diplomatic window that opened in 2018 had largely closed by the end of Moon's presidency, as North Korea resumed missile testing and disengaged from dialogue.

Moon's economic policies left a mixed legacy. The minimum wage increase and workweek reduction were significant structural changes to the South Korean labor market, but critics pointed to the rising housing costs in Seoul and the economic difficulties faced by small businesses during his tenure as counterweighing factors. The housing crisis, in particular, was cited as a significant contributor to the Democratic Party's loss in the 2022 presidential election.

The 2025 bribery indictment added a new dimension to assessments of Moon's legacy, placing him in the troubled tradition of South Korean ex-presidents facing criminal charges after leaving office. Previous presidents including Chun Doo-hwan, Roh Tae-woo, Lee Myung-bak, and Park Geun-hye had all faced prosecution or conviction after their terms, making the legal troubles of former presidents a recurring feature of South Korean political life.

As of 2025, political commentators continued to assess Moon's influence on the Democratic Party and South Korean liberalism more broadly. Analysis in South Korean media discussed the extent to which the policies and political orientation of his presidency continued to shape the direction of the Democratic Party under subsequent leadership.
