Reportedly educated in G\u00fcmligen, <a href=\"https:\/\/www.britannica.com\/place\/Switzerland\" class=\"md-crosslink \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">Switzerland<\/a>, at the International School of Berne, he went on to study at Kim Il-Sung National War College in <a href=\"https:\/\/www.britannica.com\/place\/Pyongyang\" class=\"md-crosslink \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">P\u2019y\u014fngyang<\/a> from 2002 to 2007. As a young adult, Kim Jong-Un began accompanying his father on military inspections. It was thought that he worked either for the <a href=\"https:\/\/www.britannica.com\/topic\/Korean-Workers-Party\" class=\"md-crosslink \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">Korean Workers\u2019 Party<\/a> (KWP; the <a href=\"https:\/\/www.britannica.com\/topic\/nation-state\" class=\"md-crosslink autoxref \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">country\u2019s<\/a> ruling party) or in the army\u2019s General Political Bureau; both organizations were involved in <a class=\"md-dictionary-link md-dictionary-tt-off eb\" data-term=\"surveillance\" href=\"https:\/\/www.britannica.com\/dictionary\/surveillance\" data-type=\"EB\" rel=\"nofollow noopener\" target=\"_blank\">surveillance<\/a> of government officials.<\/p>\n<p class=\"topic-paragraph\">Rumours began to circulate early in 2009 that he was being groomed as his father\u2019s eventual successor. He was listed as a candidate for the <a href=\"https:\/\/www.britannica.com\/topic\/Supreme-Peoples-Assembly\" class=\"md-crosslink \" rel=\"nofollow noopener\" target=\"_blank\">Supreme People\u2019s Assembly<\/a> in 2009, and that April he was given a post on the powerful <a href=\"https:\/\/www.britannica.com\/topic\/National-Defense-Commission\" class=\"md-crosslink \" rel=\"nofollow noopener\" target=\"_blank\">National Defense Commission<\/a> (NDC); the chairmanship of the NDC, defined in the constitution as the country\u2019s highest office, was held by Kim Jong Il. By mid-2009 Kim Jong-Un was being referred to within the country by the title \u201cBrilliant Comrade,\u201d and in June it was reported that he had been named head of the State Security Department, the government agency responsible for political control and counterintelligence. That year he also reportedly married Ri Sol-Ju. In September 2010 Kim Jong-Un was given the high rank of four-star general, although he was not known to have had any prior military experience. The timing of his appointment was considered significant, as it came shortly before the first general meeting of the KWP since the session in 1980 at which his father had been named <a href=\"https:\/\/www.britannica.com\/biography\/Kim-Il-Sung\" class=\"md-crosslink \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">Kim Il-Sung<\/a>\u2019s successor. Over the next year his own position as successor became clearer.<\/p>\n<p><a class=\"link-module shadow-sm d-block qa-read-more-module\" href=\"http:\/\/www.britannica.com\/place\/North-Korea\/Relations-with-the-South#ref1042174\" rel=\"nofollow noopener\" target=\"_blank\"><\/p>\n<p>        <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.europesays.com\/korea\/wp-content\/uploads\/2026\/05\/Flag-North-Korea.jpg\" alt=\"North Korea\" class=\"rounded-sm mr-15\" width=\"70\"\/><\/p>\n<p>More From Britannica<\/p>\n<p>North Korea: The rise and rule of Kim Jong-Un<\/p>\n<p><\/a> <\/p>\n<p class=\"topic-paragraph\">After the death of his father in December 2011, Kim Jong-Un was declared the country\u2019s supreme leader, an unofficial title that nonetheless signaled his position as the head of both the government and North Korea\u2019s military forces. In April 2012 his status was validated by the acquisition of several official titles: first secretary of the KWP, chairman of the Central Military Commission, and chairman of the NDC, which was then the country\u2019s highest <a class=\"md-dictionary-link md-dictionary-tt-off mw\" data-term=\"bureaucratic\" href=\"https:\/\/www.merriam-webster.com\/dictionary\/bureaucratic\" data-type=\"MW\" rel=\"nofollow noopener\" target=\"_blank\">bureaucratic<\/a> authority. Kim\u2019s national strategy of byungjin (often translated as \u201cparallel development\u201d), which emphasized the development of the country\u2019s economy along with its defense capabilities, was officially adopted during a 2013 meeting of the KWP central committee. In June 2016 the congress of the Supreme People\u2019s Assembly revised the constitution to broaden and solidify Kim Jong-Un\u2019s position. The revisions created a new organization, the State Affairs Commission, with Kim as its head. The new commission replaced the NDC as North Korea\u2019s most powerful governing agency.<\/p>\n<p> Leader of North Korea <\/p>\n<p class=\"topic-paragraph\">The early years of Kim\u2019s reign were <a class=\"md-dictionary-link md-dictionary-tt-off eb\" data-term=\"characterized\" href=\"https:\/\/www.britannica.com\/dictionary\/characterized\" data-type=\"EB\" rel=\"nofollow noopener\" target=\"_blank\">characterized<\/a> by a ruthless consolidation of power and the sharp acceleration of North Korea\u2019s <a href=\"https:\/\/www.britannica.com\/technology\/nuclear-weapon\" class=\"md-crosslink \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">nuclear weapons<\/a> program. In December 2013 Kim executed his uncle <a href=\"https:\/\/www.britannica.com\/biography\/Jang-Song-Thaek\" class=\"md-crosslink \" rel=\"nofollow noopener\" target=\"_blank\">Jang Song-Thaek<\/a>, saying that he had \u201cremoved the scum\u201d from the KWP. Jang was a member of Kim Jong Il\u2019s inner circle and had served as a virtual regent for the younger Kim after his father\u2019s death. Jang\u2019s execution also marked a break with Beijing, as Jang had long been an advocate of closer ties with China. Although Jang was the highest-profile official to be purged by Kim, defectors and South Korean intelligence services reported that people who had displeased the regime were being executed on a routine basis. In several cases, individuals who reportedly had been killed in a spectacularly grisly fashion resurfaced years later; such instances provided a clear illustration of just how difficult it was to obtain accurate information about events inside North Korea.<\/p>\n<p class=\"topic-paragraph\">Under <a href=\"https:\/\/www.britannica.com\/biography\/Kim-Jong-Il\" class=\"md-crosslink \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">Kim Jong Il<\/a>, North Korea\u2019s nuclear weapons program had advanced in fits and starts. The country\u2019s first underground nuclear detonation, in October 2006, came just months after a series of <a href=\"https:\/\/www.britannica.com\/technology\/ballistic-missile\" class=\"md-crosslink autoxref \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">ballistic missile<\/a> tests, but observers characterized these early forays as middling successes at best. After February 2013, which saw the first nuclear test of the Kim Jong-Un regime, the pace of both underground detonations and long-range missile tests quickened dramatically. By 2017 North Korea had conducted a total of six nuclear tests, including at least one of a device that North Korean officials claimed was small enough to mount on an <a href=\"https:\/\/www.britannica.com\/technology\/ICBM\" class=\"md-crosslink \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">intercontinental ballistic missile<\/a>.

Nevertheless, in the weeks before the 2018 <a href=\"https:\/\/www.britannica.com\/sports\/Winter-Olympic-Games\" class=\"md-crosslink autoxref \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">Winter Olympic Games<\/a> in P\u2019y\u014fngch\u2019ang (Pyeongchang), South Korea, the two countries initiated a <a class=\"md-dictionary-link md-dictionary-tt-off mw\" data-term=\"dialogue\" href=\"https:\/\/www.merriam-webster.com\/dictionary\/dialogue\" data-type=\"MW\" rel=\"nofollow noopener\" target=\"_blank\">dialogue<\/a> that led to North and South Korean athletes marching into the opening ceremonies as a single body and under a flag that depicted a unified Korea.

At that time, Kim stated that he was open to discussing the elimination of North Korea\u2019s nuclear <a class=\"md-dictionary-link md-dictionary-tt-off eb\" data-term=\"arsenal\" href=\"https:\/\/www.britannica.com\/dictionary\/arsenal\" data-type=\"EB\" rel=\"nofollow noopener\" target=\"_blank\">arsenal<\/a> if the United States was willing to guarantee the security of North Korea and his regime. That announcement was followed by talk of an unprecedented summit between Kim and Trump, which the Trump administration indicated would take place in or before May 2018. On April 27, 2018, Kim and Moon met for a historic summit at the \u201cpeace village\u201d of <a href=\"https:\/\/www.britannica.com\/place\/Panmunjom\" class=\"md-crosslink \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">P\u2019anmunj\u014fm<\/a>. It marked the first time that the leaders of the two Koreas had met face-to-face in more than a decade, and the pair discussed the denuclearization of the Korean peninsula and the conclusion of an armistice that would officially end the Korean War.<\/p>\n<p>\n\t\t\t\tQuick Facts<\/p>\n<p>\t\t\t\t\t\t\t\tAlso spelled:<br \/>\n\t\t\t\t\t\t\t\tKim Jong-Eun<\/p>\n<p>\t\t\t\t\t\t\t(Show\u00a0more)<\/p>\n<p class=\"topic-paragraph\">By mid-May the details of the meeting between Kim and Trump had begun to <a class=\"md-dictionary-link md-dictionary-tt-off eb\" data-term=\"crystallize\" href=\"https:\/\/www.britannica.com\/dictionary\/crystallize\" data-type=\"EB\" rel=\"nofollow noopener\" target=\"_blank\">crystallize<\/a>. The summit was scheduled to be held in <a href=\"https:\/\/www.britannica.com\/place\/Singapore\" class=\"md-crosslink \" data-show-preview=\"true\" rel=\"nofollow noopener\" target=\"_blank\">Singapore<\/a>. However, a fresh war of words broke out between Washington and P\u2019y\u014fngyang.

North Korean officials responded that Pence\u2019s statement was \u201cignorant and stupid.\u201d On May 24 Trump announced that he was pulling out of the meeting, and Kim\u2019s government immediately adopted a conciliatory tone, urging Trump to reconsider. Eight days later Trump reversed himself and announced that the <a class=\"md-dictionary-link md-dictionary-tt-off eb\" data-term=\"summit\" href=\"https:\/\/www.britannica.com\/dictionary\/summit\" data-type=\"EB\" rel=\"nofollow noopener\" target=\"_blank\">summit<\/a> would proceed as planned. On June 12, 2018, for the first time in history, the leaders of the United States and North Korea met face-to-face. Kim pledged to work \u201ctoward complete denuclearization of the Korean peninsula\u201d while Trump promised to end joint U.S.\u2013South Korea military exercises.<\/p>\n","protected":false},"excerpt":{"rendered":"Childhood and rise to power The youngest of Kim Jong Il\u2019s three sons, Kim Jong-Un lived most of&hellip;\n","protected":false},"author":2,"featured_media":1195,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[170,1252,1251,1250,141,31,34],"class_list":{"0":"post-1194","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-north-korea","8":"tag-article","9":"tag-britannica","10":"tag-encyclopeadia","11":"tag-encyclopedia","12":"tag-kim-jong-un","13":"tag-korea","14":"tag-north-korea"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/1194","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/comments?post=1194"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/1194\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media\/1195"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media?parent=1194"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/categories?post=1194"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/tags?post=1194"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
