NAME Kim Jong Un, also written Kim Jong-un or Kim Jong Eun. In Korean usage, Kim is the family name. His principal offices are general secretary of the Workers’ Party of Korea and president of the State Affairs Commission. (1), (2)
WHAT FAMOUS FOR Kim Jong Un is the supreme leader of the Democratic People’s Republic of Korea, commonly called North Korea. The third ruler of the Kim dynasty, he succeeded his father, Kim Jong Il, in December 2011 and is the grandson of the state’s founder, Kim Il Sung. His rule has combined severe political repression with accelerated nuclear and ballistic-missile development. (3)
BIRTH Kim was born on January 8, probably in 1984, although 1982 and 1983 have also been reported. The United States government has used 1984, while North Korean statements have favoured 1982. Even his birthplace has not been conclusively established. (4)
FAMILY BACKGROUND His father, Kim Jong Il (1941–2011), ruled North Korea from 1994 until his death; his paternal grandfather, Kim Il Sung (1912–1994), founded the country. Below are portraits of Kim Jong Un's father and grandfather (Arirang Festival mass games in Pyongyang)

His mother, Ko Yong Hui, was an ethnic Korean born in Osaka, Japan, in 1952 to a Zainichi Korean family whose roots lay on Jeju Island. She was Japanese-born, rather than “half-Japanese” as sometimes claimed, and moved to North Korea as a child. (5)
Kim’s full brother is Kim Jong Chul and his sister is the influential official Kim Yo Jong; he also had an older half-brother, Kim Jong Nam.
His great-grandfather Kim Hyong Jik was a teacher, Korean independence activist, Christian and part-time Protestant missionary. (6)
CHILDHOOD Kim grew up amid guarded villas, swimming pools, bowling alleys and exceptional privilege during years when many North Koreans suffered famine. North Korean propaganda later presented him as a child prodigy: a teachers’ manual claimed that he could drive and shoot at the age of three and win a yacht race at nine. These were state-sponsored legends, not verified biographical facts. (7), (8)
The route by which he became heir is more complicated than the familiar Disneyland story. Kim Jong Nam, once considered a possible successor, was detained at Tokyo’s Narita Airport in May 2001 while travelling on a false passport and said that he wanted to visit Tokyo Disneyland. The humiliation contributed to his fall from favour, after which Jong Un eventually emerged as Kim Jong Il’s chosen successor. (9)
EDUCATION Kim lived secretly in Switzerland. A boy identified as him attended the Liebefeld-Steinhölzli state school in Köniz, near Bern, as “Pak Un,” supposedly the son of a North Korean embassy employee, from 1998 until late 2000. Other evidence suggests that he had been in Switzerland earlier and may also have attended the International School of Berne. (10)
Former classmates remembered a quiet, private pupil who initially struggled with German but became more sociable. He was far more absorbed in basketball—especially Michael Jordan and the Chicago Bulls—than in academic work and was intensely competitive on court. After returning home, he reportedly studied at Kim Il Sung University and Kim Il Sung Military University, obtaining qualifications in physics and military studies. (11)
North Korean education devotes considerable time to ideological instruction and praise of the ruling family. The claim that exactly one-third of every pupil’s instruction concerns the Kims cannot be established as a universal figure, but elementary curricula include separate subjects about family members, and an 81-hour secondary-school course on Kim Jong Un was introduced in 2014. (12), (13)
CAREER RECORD 2009 Appointed to North Korea's National Defence Commission and secretly designated by his father, Kim Jong Il, as the official heir to the leadership—passing over his eldest half-brother, Kim Jong Nam, who had fallen out of favour after trying to sneak into Japan on a forged passport to visit Disneyland.
2010 Made a four-star general in the Korean People's Army and appointed Vice Chairman of the Central Military Commission of the Workers' Party of Korea.
2011 Declared Supreme Commander of the Korean People's Army following the death of Kim Jong Il on December 17, 2011.
2012 Formally assumed the top leadership titles, including First Secretary of the Workers' Party of Korea and Chairman of the Central Military Commission.
2016 Elected Chairman of the newly created State Affairs Commission, solidifying absolute governance over state institutions.
2018 Held historical summits with South Korean President Moon Jae-in and U.S. President Donald Trump in Singapore, becoming the first North Korean leader to meet a sitting U.S. President.
2021 Elevated his title to General Secretary of the Workers' Party of Korea, further centralising control over party administration.
APPEARANCE Kim is a short, heavy-set man with a broad face and closely shaved sides beneath a high, swept-back top. His hairstyle, gestures, horn-rimmed glasses and rounded silhouette have often been interpreted as deliberate echoes of Kim Il Sung, whose image possessed greater warmth and revolutionary legitimacy than that of Kim Jong Il. (14)

FASHION His signature garment is a dark, high-collared Mao-style suit, often subtly pinstriped, worn with polished black shoes. It presents socialist continuity and visually links him to his grandfather, although Kim sometimes adopts Western business suits, overcoats or a black leather trench coat to project a younger, more modern image. (15)
CHARACTER School acquaintances described him as introverted, decisive, humorous and fiercely competitive, with a temper when he lost at basketball. As ruler he has appeared calculating, risk-tolerant and ruthless in removing possible rivals, while using smiles, embraces and informal “field guidance” to appear more approachable than his father. (11), (16)
SPEAKING VOICE Kim’s first televised public address, delivered at a military parade on April 15, 2012, lasted about twenty minutes. Contemporary reports described a youthful voice and a hesitant delivery; he kept his eyes largely on his prepared text. Regular public speeches marked a contrast with his taciturn father and associated him with his more demonstrative grandfather. (17), (18)
SENSE OF HUMOUR Former classmates recalled that Kim could be funny and “good for a laugh.” Dennis Rodman has described private occasions filled with laughter, karaoke, skiing and horse riding, although Rodman’s unusually friendly account cannot be treated as an impartial assessment of Kim’s character. (11), (19)
RELATIONSHIPS Kim is married to Ri Sol Ju, a former singer whose status as his wife was publicly confirmed in July 2012.

They are widely believed to have three children, although only a daughter—believed to be Kim Ju Ae—has appeared publicly. First shown beside an intercontinental missile in November 2022, she became increasingly prominent and by 2026 was assessed by South Korean intelligence as being positioned as a probable successor. (20)
His most unlikely foreign friendship is with retired American basketball player Dennis Rodman, who has visited North Korea repeatedly. Rodman revealed Ju Ae’s reported name after meeting the family in 2013. (19)
MONEY AND FAME No credible audit can separate Kim’s personal wealth from assets controlled by the North Korean state, so widely circulated multibillion-dollar “net worth” figures are speculative. Satellite research has nevertheless identified numerous luxurious family compounds with yachts, pools and equestrian facilities. A 2024 South Korean report estimated spending of up to $1.8 billion on vehicles, luxury goods, medical care and rewards for the elite. (21)
Kim’s face and activities dominate North Korean news, school materials and propaganda films. In 2011, as he was being prepared for succession, authorities reportedly instructed others bearing his name to change it “voluntarily”—a word carrying little practical choice in a dictatorship. (22)
FOOD AND DRINK Accounts from visitors and former household staff describe a taste for expensive cheese, wine, seafood, caviar and spirits, but many colourful claims about his diet are difficult to verify. His access to imported luxuries contrasts with persistent food insecurity among ordinary North Koreans. (23), (24)
A related family legend says that Kim Jong Il invented the hamburger. North Korean reporting actually credited the elder Kim with introducing a “double bread with meat,” or gogigyeopbbang, around 2000 and ordering its production for university students. It was a renamed hamburger rather than an original invention by Kim Jong Un. (25)
MUSIC AND ARTS Kim established the all-female Moranbong Band in 2012 as a modern showcase for state-approved pop and spectacle. Its debut unusually included Disney imagery and arrangements of Western music. Rodman has said that Kim enjoys 1980s American music, Frank Sinatra and karaoke. (19)
LITERATURE State publishing houses generate vast collections of ideological literature and political treatises credited to Kim Jong Un, which form mandatory reading material for North Korean citizens.

His first major address was titled Let Us March Forward Dynamically Towards Final Victory, Holding Higher the Banner of Songun, and a collection called Aphorisms appeared in 2016. (18)
There is little reliable evidence about Kim’s private reading.
NATURE State photography repeatedly places Kim on a white horse at snowy Mount Paektu, the mountain central to the dynasty’s revolutionary mythology. The carefully staged images convey vigour, sacred lineage and national destiny rather than documenting a personal commitment to conservation. (26)
PETS He is frequently shown with horses, and in 2024 he presented Vladimir Putin with two Pungsan hunting dogs, a native Korean breed, during Putin’s visit to Pyongyang. (27)
HOBBIES AND SPORTS Basketball has been Kim’s best-documented enthusiasm since adolescence. In Switzerland he wore Chicago Bulls kit and Air Jordan shoes, played almost daily and hated losing; as leader he hosted Rodman and a basketball exhibition in Pyongyang.
He has also been associated with horse riding, skiing, yachting and jet-skiing. (11), (19)
SCIENCE AND MATHS Kim reportedly earned a physics qualification, although the secrecy surrounding his education makes its academic value impossible to assess. His government has promoted science, technology, computing and distance learning, extended compulsory education from eleven to twelve years and emphasized technical training as a route to economic and military self-reliance. (1), (28)
PHILOSOPHY & THEOLOGY Kim officially upholds Kimilsungism-Kimjongilism and Juche, the dynasty’s doctrine of political independence and self-reliance, reinforced by the Suryong principle of absolute leadership.
North Korea is formally secular, but researchers compare its compulsory veneration of the Kim family to a state-sponsored theology; unauthorized religious belief and practice are severely punished. (29)
LEADER OF NORTH KOREA Kim Jong Un began to emerge as his father Kim Jong Il’s intended successor in the late 2000s, reportedly receiving posts within North Korea’s security and defence apparatus. It was not the sort of career progression that involved submitting a CV, attending an interview and waiting nervously for an email. In North Korea, the succession plan was rather more of a family matter.
In 2010, Kim was publicly promoted to four-star general and appointed vice-chairman of the Workers’ Party’s Central Military Commission, despite having no known military command experience. This was an impressive achievement for a young man whose military career had barely begun, rather like being made admiral after successfully finding the swimming pool.
After Kim Jong Il died on December 17, 2011, Kim Jong Un was proclaimed the “great successor” and assumed supreme command of the Korean People’s Army. A January 2011 directive reportedly ordered North Koreans who were already named Kim Jong Un to change their names and prohibited parents from giving the name to newborn children. It is difficult to imagine many governments having quite such a low tolerance for nominative competition.
In 2012, Kim became first secretary of the Workers’ Party, chairman of its Central Military Commission and first chairman of the National Defence Commission. In July he was awarded the rank of marshal, completing an extraordinarily rapid ascent through the military hierarchy. Most people have to spend years working their way up an organisation; Kim had the advantage of being the organisation’s next owner.
Between 2013 and 2017, Kim consolidated his power through purges while North Korea conducted four nuclear tests and accelerated its missile programme. In November 2017, the country tested the Hwasong-15 intercontinental ballistic missile, after which Kim declared North Korea’s nuclear force complete. This was an unusually confident use of the word “complete,” given that the missiles and nuclear weapons had presumably not received the memo.
In 2016, Kim was elected chairman of the Workers’ Party and became chairman of the newly created State Affairs Commission, further concentrating political and military authority in his hands. North Korea had never been especially enthusiastic about spreading power around, but Kim was clearly determined to make certain nobody misunderstood the point.
In 2018 and 2019, Kim embarked on an extraordinary period of diplomacy. He held three summits with South Korean president Moon Jae-in and three unprecedented meetings with US president Donald Trump, in Singapore, Hanoi and at the Korean Demilitarized Zone. The meetings temporarily reduced tensions and produced an impressive collection of handshakes and photographs, but no lasting agreement on denuclearisation. Diplomacy had, at least briefly, replaced missile tests as the preferred form of international theatre.
In 2021, Kim adopted the title general secretary of the Workers’ Party, the same title previously held by his father and grandfather. Political titles in North Korea have a pleasingly hereditary quality, rather like a family recipe, except that this one comes with considerably more artillery.
From 2023 to 2025, Kim strengthened North Korea’s strategic and military ties with Russia. He met Vladimir Putin in Russia’s Far East in 2023, while Putin visited Pyongyang in 2024. In September 2025, Kim travelled to Beijing to attend China’s Victory Day parade, his first appearance at a multilateral gathering of foreign leaders. After years of relative isolation, he was now becoming a considerably more regular presence on the international stage.
In February 2026, the Ninth Congress of the Workers’ Party re-elected Kim as general secretary. The following month, the Supreme People’s Assembly reappointed him as president of the State Affairs Commission, confirming his position at the centre of North Korea’s political system. After all, when your grandfather founded the family business, your father ran it and you have inherited it, there is little reason to worry about an uncertain career path.
POLITICS Kim presides over a hereditary totalitarian system centred on the Workers’ Party, security agencies and armed forces. He initially combined limited market tolerance and high-profile construction with byungjin—the parallel pursuit of economic development and nuclear weapons—but after the failed Hanoi summit emphasized self-reliance, weapons expansion and closer alignment with Russia. In the 2020s he abandoned the older goal of peaceful Korean reunification and treated South Korea as a separate hostile state. (3), (30)
SCANDAL The gravest issue is state repression. A United Nations commission found that North Korean authorities had committed crimes against humanity including extermination, murder, enslavement, torture, imprisonment, sexual violence, enforced disappearance and deliberately prolonged starvation. It warned Kim that command responsibility could make him personally accountable.
Kim’s uncle by marriage, Jang Song Thaek, was arrested and executed in December 2013 during a sweeping consolidation of power, officially for treason and factional activity. (31)
Kim’s estranged half-brother Kim Jong Nam was assassinated with VX nerve agent at Kuala Lumpur International Airport in February 2017; investigators linked the operation to North Korea, although Pyongyang denied responsibility. (9),
MILITARY RECORD Kim has no known battlefield service. His four-star generalship in 2010 was a political appointment designed to prepare the succession, but he later made military modernization his regime’s central achievement. Under him North Korea carried out four of its six nuclear tests and developed intercontinental, submarine-launched, hypersonic and solid-fuel missiles. (32)
HEALTH AND PHYSICAL FITNESS Kim is a heavy smoker and has long been obese; photographs have also shown periods of weight loss, a limp and apparent difficulty walking. In September 2026 South Korea’s intelligence service assessed him at more than 140 kilograms and at high cardiovascular risk, while reporting no immediate sign that he was unable to perform normal activities. North Korea’s secrecy makes recurrent stories of operations, comas or imminent death unreliable. (23)
A persistent lesion on Kim’s left cheek, first discernible in photographs from December 2020, appeared to increase in size over the following years and was estimated at approximately one centimetre by June 2024. Dermatologists examining photographs suggested several possible explanations, including a wart, cutaneous horn or keratoacanthoma, but no diagnosis has been confirmed. South Korean intelligence has separately reported that Kim suffers from dermatitis associated with allergies and stress. (33)

HOMES The ruling family uses numerous heavily secured residences. Satellite imagery has revealed coastal villas around Wonsan, private islands, marinas, yachts, pools, a riding track and shooting facilities. Former guest Dennis Rodman compared the Wonsan retreat to a private version of Hawaii or Ibiza. (34)
TRAVEL Kim has often used an armoured train for international diplomacy. His known foreign journeys as leader have taken him to China, Singapore, Vietnam, Russia and the southern side of the inter-Korean border; he has met Xi Jinping, Moon Jae-in, Donald Trump and Vladimir Putin. (35)
In September 2025 he travelled to Beijing with Kim Ju Ae for a major Chinese military parade, giving his daughter her international debut. (20)
APPEARANCES IN MEDIA Within North Korea, Kim appears constantly in Korean Central Television news, “field guidance” reports and documentaries that depict him as a soldier, builder and benevolent father. The 2022 propaganda film The Great Year of Victory, 2021 showed him riding a white horse, visiting construction projects and apparently limping while its narration praised his self-sacrifice.
Outside North Korea he has become a frequent subject of news documentaries, memes and satire. Randall Park played a fictionalized Kim in the 2014 film The Interview, in which American television journalists are recruited to assassinate him. Pyongyang condemned the film, whose release became entangled with the cyberattack on Sony Pictures.
ACHIEVEMENTS From the regime’s perspective, Kim’s greatest achievements are the secure consolidation of dynastic power, North Korea’s emergence as a credible nuclear-armed state, major advances in long-range missiles and unprecedented summit diplomacy with a serving US president. He also oversaw showpiece housing and resort projects and education reforms stressing science and technology.
These gains came at enormous cost. Diplomacy did not bring sanctions relief or denuclearization, economic improvement remained uneven, food insecurity persisted, and political freedom and human rights remained severely restricted. His record is therefore one of successful regime survival and military advancement rather than broad prosperity for North Koreans.
