The 'Mount Paektu bloodline' is the official North Korean propaganda term for the ruling dynasty that has devastated the North Korean people for more than 70 years. It details how Kim Il Sung, Kim Yo Jong’s grandfather and the country’s founder, used Korea’s highest mountain as a staging area for guerrilla operations to defeat the Japanese colonial masters in 1945. This narrative serves as the ideological foundation of the Kim family’s rule.

Kim Yo Jong, the youngest child of former North Korean leader Kim Jong Il and his consort, Ko Yong-hui, was born in Pyongyang on September 26, 1987. She spent most of her early childhood at her mother's residence and later studied in Switzerland under the assumed name 'Pak Mi-hyang'.

In 1998, one of Kim Yo Jong and Kim Jong Un's aunts defected to the United States, which is considered a significant event in the context of North Korean politics and society.

In 2007, Kim Yo Jong was appointed as a junior cadre in the ruling Workers' Party of Korea (WPK), possibly working under her father or her aunt, Kim Kyong-hui. She was active in establishing her father's hereditary succession campaign and worked in the National Defense Commission and in her father's personal secretariat.

Kim Yo Jong received much publicity during the funeral service for Kim Jong Il in December 2011, appearing alongside Kim Jong Un and leading groups of senior party officials in bowing at her father's casket.

At the beginning of 2012, Kim Yo Jong was reportedly given a position at the National Defence Commission as tour manager for her brother, Kim Jong Un, arranging his itineraries, schedule, logistical needs, and security arrangements.

In March 2014, Kim Yo Jong received her first official mention in state media when she accompanied her brother in voting for the Supreme People's Assembly and was named a 'senior official' of the WPK Central Committee.

In October 2014, Kim Yo Jong was reported to have taken over state duties for her brother while he underwent medical treatment.

In November 2014, Kim Yo Jong was appointed First Deputy Director of the party's Propaganda and Agitation Department.

Kim Yo-jong reportedly gave birth to a child in May 2015.

In July 2015, reports described Kim Yo Jong as playing the role of de facto leader of the Propaganda and Agitation Department, responsible for 'assisting in consolidating Kim Jong-un's power' by implementing 'idolisation projects'.

Kim Yo Jong served as an alternate member of the WPK’s Politburo from October 8, 2017, to January 2021. There is uncertainty regarding the capacity in which she served in this position, with speculation of demotion and reinstatement. As of January 2021, she no longer holds this position. She has also been alternately listed as “first vice department director” to “vice department director” of the Politburo.

Ko Yong Hui, the mother of Kim Yo Jong and Kim Jong Un, was born in Japan, which is one of the hidden secrets of the Kim family and holds importance in understanding the family's background.

Kim Yo-jong attended the 2018 Winter Olympics opening ceremony in Pyeongchang, South Korea, marking the first visit of a member of the ruling Kim dynasty to South Korea since the Korean War. She met with South Korean President Moon Jae-in and revealed that she was dispatched as a special envoy of Kim Jong Un, delivering a personally written letter from Kim to Moon.
