- Kim Jong Un is the third member of the Kim family to serve as leader of North Korea.
- His grandfather Kim Il Sung was the first, and he started an unusual dynastic succession.
- Photos show how the mysterious, powerful family has ruled the country for decades.
Kim Jong Un became the leader of North Korea in 2011. As a third-generation ruler, he followed in the footsteps of his father and grandfather, who first came to power at the country’s founding.
“Having this kind of dynastic succession in a so-called communist state is unheard of,” Jung H. Pak, author of “Becoming Kim Jong Un,” told Business Insider. “They’re very focused on making sure that that bloodline is the one that leads the position of power,” she added.
Maintaining the dynasty has required secrecy and mythologizing for decades. While it can still be difficult to verify basic information about some members, the country is more open than it once was.
“There’s way less secrecy than there used to be about the leader of North Korea’s family,” Michael Madden, the founder of NK Leadership Watch, told BI. For example, Kim Jong Un’s children are more public than he was as a child.
Here’s the Kim family history in pictures.
Kim Jong Un’s grandfather Kim Il Sung was North Korea’s first leader.
In 1948, Kim Il Sung came to power and served as the country’s ruler until his death in 1994.
Japan’s colonization of Korea deeply affected Kim Il Sung.
Japan colonized the Korean peninsula between 1910 and 1945. Kim Il Sung was born in 1912, and his father was later jailed for his activism for independence. Visiting his beaten and bruised father in prison sparked an anti-Japanese zeal in Kim Il Sung, according to his memoir, quoted in “Becoming King Jung Un.”
Both of his parents died young, his father at 31 and his mother at 40.
Starting in the 1930s, Kim Il Sung became a guerilla fighter.
In 1931, Japan invaded Manchuria, a region of China. Kim Il Sung led Chinese and Korean guerilla fighters in killing Japanese police and soldiers. He and his group then made their way to the Soviet Union in 1940 as pressure from the Japanese troops increased.
There, he received military training and became captain of a Red Army brigade.
Kim Jong Suk, Kim Jong Un’s grandmother, was a fellow guerilla fighter.
Kim Jong Suk was in her late teens when she met up with Kim Il Sung in Manchuria in 1935. First helping in the kitchens, she became a fighter, and Kim Il Sung credited her with saving his life in his memoir. The two married in the early 1940s.
Much about their lives together at this point is unknown. “The records are sort of foggy,” Madden said.
In 1941, she gave birth to her first child, Kim Jong Il.
The couple was still in the Soviet Union at the time. Later, officials would alter Kim Jong Il’s birth to a year later, to match more closely with his father’s, 1912.
After years away from Korea, Kim Il Sung returned and rose to power.
The Soviet Union and the US divided the Korean peninsula in two in 1945. Despite fierce competition for the role, Kim Il Sung became the leader of the northern portion with the help of the Soviet Union.
Three years later, the Democratic People’s Republic of Korea was established.
In 1949, Kim Jong Suk died.
The cause was an ectopic pregnancy, according to Kim Il Sung’s memoir.
She was seen as the mother of the country.
Kim Il Sung’s memoir contributed to some of the myth-making around Kim Jong Suk. Not only did she save his life, she sacrificed her hair to use as insulation for his boots.
It was important that she also be seen as nurturing, Pak said: “She supported her husband, the revolutionary.”
Kim Il Sung wanted to reunify Korea.
In 1950, North Korea invaded its neighbor, quickly capturing Seoul. The war lasted three years, during which the US heavily bombed the northern part of the peninsula. It ended with an armistice but no peace treaty.
Though the peninsula remained split, Kim Il Sung declared it a victory for North Korea.
Following his first wife’s death, Kim Il Sung remarried.
Two of Kim Il Sung’s children, Kim Jong Il and Kyong Hui, moved to China during the Korean War, away from the fighting. A third child, Kim Man Il, drowned in 1947.
During the war, Kim Il Sung married Kim Song Ae, whom he began an affair with during his first marriage. The couple eventually had at least two sons.
“It’s got to be devastating trauma” for the siblings to return after the war ends to find a new family, Madden said.
Throughout his rule, Kim Il Sung’s persona became larger than life.
As Kim Il Sung continued his rule in the 1950s, he pushed his idea of juche, an ideology of Korean socialism that explained away difficult living conditions as necessary for creating a great nation.
He became part paternal authority figure, part Santa Claus, with the power to both punish and reward.
“After all, without Kim Il Sung, they as a nation and as a people would not exist, which schoolchildren learned in their textbooks and through lectures about their ‘father’s’ heroic deeds and adventures,” according to “Becoming Kim Jong Un.”
After over 45 years of rule, Kim Il Sung died in 1994.
Given his mythological status, it was unclear who would rule the country next.
It wasn’t a given that Kim Jong Il would succeed his father.
Initially, Kim Il Sung’s younger brother, Kim Yong Ju, seemed a potential candidate for succession in the late 1960s. His children from his second marriage may have also had a claim to the position.
By the late 1970s, though, Kim Il Sung had chosen his son Kim Jong Il as the country’s next leader. While Kim Jong Il lacked his father’s military background and force of personality, he had already secured leadership positions by that time.
“Kim Jong Il’s very ambitious,” Madden said. “He’s got axes to grind.” That included conflict with his stepmother and half-siblings. He used his clout to have his half-brother Pyong Il sent to a distant post.
Myths about Kim Jong Il made him seem like a genius born to succeed his father.
With his storied history as a guerilla fighter and decades to build up his deified image, Kim Il Sung was a tough act to follow. “Kim Jong Il did not have those credentials, and they had to make things up for him,” Pak said.
According to legend, a shining star appeared in the sky on the day Kim Jong Il was born. He could walk and talk by the time he was 2 months old. As a kindergartener, he understood military tactics.
Before succeeding his father, Kim Jong Il took an interest in movie-making.
One of Jong Il’s earliest posts was cultural arts director of the Propaganda and Agitation Department. A fan of James Bond and Elizabeth Taylor, he parlayed his interest in filmmaking into a way to feed the mystique around his father and his legacy.
He was also known as a partier and womanizer, according to “Becoming Kim Jong Un.”
Kim Jong Il inherited a country rife with problems.
North Korea spent years isolated from other countries, with a declining economy and a cowed population. “Their tools were coercion, violence, repression, and propaganda to create a culture of fear,” Pak wrote of the Kim family.
By 1994, the Soviet Union had recently collapsed, so Kim Jong Il had also lost his father’s biggest ally. He saw nuclear weapons as the key to holding onto power. In 2006, the country announced its first nuclear test.
Kim Jong Il had multiple wives.
While Jong Il didn’t seem to mind the spotlight, he kept his private life under wraps. His wives and domestic partners were hidden in lavish homes around Pyongyang.
He had children with Song Hye Rim, Kim Young Sook, and Ko Young Hui.
“Having multiple wives and children would have undermined Kim Jong Il’s own political leadership succession in North Korea,” Madden said.
Kim Jong Nam was Kim Jong Il’s eldest son.
His mother, Song Hae Rim, was a North Korean actor who divorced a novelist before having a child with Kim Jong Il in 1971.
Kim Jong Il didn’t want to bring attention to his son Jong Nam.
Jong Il was worried his father would disapprove of Song Hae Rim, who was born in South Korea, and his son. He kept them isolated but spoiled Jong Nam with foreign comics and TV shows, which were severely restricted to other North Korean residents.
In 1978, Jong Nam started going to school in Moscow and then Geneva. He spent a decade getting an education outside of North Korea.
Another wife, Ko Yong Hui, gave birth to three of Kim Jong Il’s children, including Kim Jong Un.
Ko Yong Hui was an actress who was born in Japan in 1952. When she was a child, her family moved to Pyongyang as part of the country’s program to bring back Koreans who lived and worked in Japan.
“Her connection to Japan is not something that’s acknowledged” by the leadership, Pak said. “The Korean-Japanese history goes back to the colonial period, and it’s a painful period for Korea.”
In the 1970s, Ko Yong Hui was a dancer with the Mansudae Art Troupe when she met Kim Jong Il. They had their first child together in 1981, a son named Kim Jong Chol.
Soon after, his brother, Kim Jong Un, was born. (The exact year of his birth isn’t clear.) Sister Kim Yo Jong followed in 1987.
Kim Jong Un’s older brother, Jong Chol, grew up interested in music.
In 2011, Kim Jong Chol was reportedly seen in Singapore at an Eric Clapton concert. Madden said he’s more artistic and sensitive than Kim Jong Un. “He’s younger than his brother, but his personality is so headstrong and charismatic,” he said of Jong Un.
The siblings went to school in Switzerland and seemed to grow close during their time away from North Korea.
Kim Jong Un and his brother stayed with their aunt while attending school in Switzerland.
Ko Yong Suk, Kong Young Hui’s sister, took care of Kim Jong Un during his time in Switzerland.
“We lived in a normal house and acted like a normal family,” she told The Washington Post in 2016. During school holidays, they would go to the French Riviera or the Alps. Back home in North Korea, they stayed at their family’s luxury homes or traveled to a private resort on the country’s eastern coast.
In 1998, Ko Yong Suk and her husband defected to the US.
When Kim Jong Il died in 2011, Kim Jong Un filled the role of North Korea’s leader.
Kim Jong Nam and Kim Jong Chol were both older than Kim Jong Un, leading some analysts to speculate they were next in line for succession.
In some ways, Jong Nam lived a lifestyle similar to his father’s, with a rowdy social life. However, Kim Jong Il may have worried that his son was too Westernized. In 2001, Jong Nam reportedly used a fake passport to try and go to Tokyo Disneyland.
“The first son had been outside North Korea for a long time, and so you can imagine that he would not have the networks or the connections” necessary to run the country, Pak said.
It’s not clear if Jong Chol was passed over or took himself out of the running to be leader. “You need to have some strength and personality if you want to take that title,” Madden said. “And Jong Chol didn’t have that.”
In contrast, Kim Jong Un seemed like his father in appearance and demeanor, Madden said.
Kim Jong Un’s aunt Kim Kyong Hui was his father’s close ally.
“She was a very prominent North Korean elite,” Madden said. She had several roles in the important Workers’ Party of Korea and became a general in the Korean People’s Army.
Her husband was executed in 2013.
Though he was once seen as having a powerful role in the government and possibly mentoring Kim Jong Un, Jang Song Thaek was accused of corruption in 2013, according to The BBC.
A military tribunal ruled that Kim Jong Un’s uncle had attempted to overthrow the state, and he was executed by an antiaircraft gun soon after.
A few years later, Kim Jong Un’s half-brother Jong Nam was killed in Malaysia.
In 2017, two women smeared a nerve agent, VX, on Jong Nam’s face at the Kuala Lumpur International Airport. Jong Nam quickly died from exposure to the lethal substance. The woman said they thought it was part of a prank and were later released.
In 2018, the US State Department accused North Korea of being behind the attack. North Korea has denied any involvement.
What role the North Korean leader potentially had in his brother’s death is unclear.
“There are definitely people in KJU’s ear who would be stoking tension between his brother,” Madden said.
Jong Nam’s son released a video shortly after his father’s death.
Kim Han Sol spent most of his childhood in Macau, China.
He periodically gave interviews. In 2012, the teenager said, “I’ve always dreamed that one day I would go back and make things better, and make things easier for the people back there.”
In the 2017 video, Han Sol said he was with his mother and sister. The video was edited but ended with Jung Nam’s son saying, “We hope this gets better soon.”
Kim Yo Jong, Kim Jong Un’s sister, is a high-ranking member of the ruling elite.
“Kim Yo Jong has unfettered access to her brother,” Madden said.
Her role has expanded in recent years beyond promoting Kim Jong Un’s image to include acting as a political advisor and becoming involved with the military.
“She’s kind of an attack dog,” Pak said. “She says nasty things about the South Korean president and South Korea and about the US.”
Kim Yo Jong appears to have two young children, who may one day play a role in a future leader’s cabinet.
“I would anticipate the sister’s children being supporters,” Pak said. “But their place in the inner circle is completely dependent on how much they show their loyalty to the leader,” she added.
Reportedly a former cheerleader and performer, Ri Sol Ju married Kim Jong Un in 2009.
Ri Sol Ju was born in 1989. She’s played a bit of a first-lady role, attending summits and delegations alongside her husband.
“He can present her as a vision of what North Korean motherhood or womanhood should be,” Pak said. “She’s supportive. She’s pretty. She’s dressed in a very modern way and in a non-threatening way.”
More recently, she’s been less in the public eye. Reports state that she has three children with Kim Jong Un. They were born in 2010, 2013 and 2017, according to reports.
Some speculate that Kim Jong Un has found his successor in daughter Ju Ae.
When basketball player Dennis Rodman visited Pyongyang in 2013, he met one of Kim Jong Un’s children, a daughter named Ju Ae. More recently, Ju Ae, now a teenager, has been photographed at events with her father.
“If we’re looking at succession, you would want to craft that narrative of somebody who is devoted and committed to advancing and possessing a nuclear weapon program, that has the luster of revolution, that the revolutionary blood is coursing through her veins,” Pak said.
She added that it’s impossible to know if Kim Ju Ae really is being considered as the country’s future leader.
It appears that the Kim dynasty will continue into the next generation.
“She’s definitely had protocol lessons,” Madden said, from comportment to how to shake hands with officials. “I’d say her mom and her aunt Kim Yo Jong would definitely be involved in that stuff.”
Whether or not it’s Ju Ae who inherits the title, her presence is meant to cement the notion that there will be a fourth-generation leader from the Kim family, Madden said.
