History of Korea, North
From antiquity to the modern era — the historical eras, key events, and narrative that shaped Korea, North.
Overview
Korea’s traditional religions are Buddhism and Shamanism. Christian missionaries arrived as early as the 16th century, but it was not until the 19th century that major missionary activity began. Pyongyang was a center of missionary activity, and there was a relatively large Christian population in the north before 1945. Although religious groups exist in North Korea today, the government severely restricts religious activity.
By the first century AD, the Korean Peninsula was divided into the kingdoms of Shilla, Koguryo, and Paekche. In 668 AD, the Shilla kingdom unified the peninsula. The Koryo dynasty--from which Portuguese missionaries in the 16th century derived the Western name "Korea"--succeeded the Shilla kingdom in 935. The Choson dynasty, ruled by members of the Yi clan, supplanted Koryo in 1392 and lasted until Japan annexed Korea in 1910.
Throughout its history, Korea has been invaded, influenced, and fought over by its larger neighbors. Korea was under Mongolian occupation from 1231 until the early 14th century. The unifier of Japan, Hideyoshi Toyotomi, launched major invasions of Korea in 1592 and 1597. When Western powers focused "gunboat" diplomacy on Korea in the mid-19th century, Korea’s rulers adopted a closed-door policy, earning Korea the title of "Hermit Kingdom." Though the Choson dynasty recognized China’s hegemony in East Asia, Korea was independent until the late 19th century. At that time, China sought to block growing Japanese influence on the Korean Peninsula and Russian pressure for commercial gains there. The competition produced the Sino-Japanese War of 1894-95 and the Russo-Japanese War of 1904-05. Japan emerged victorious from both wars and in 1910 annexed Korea as part of the growing Japanese empire. Japanese colonial administration was characterized by tight control from Tokyo and ruthless efforts to supplant Korean language and culture. Organized Korean resistance during the colonial era was generally unsuccessful, and Japan remained firmly in control of the Peninsula until the end of World War II in 1945. The surrender of Japan in August 1945 led to the immediate division of Korea into two occupation zones, with the United States administering the southern half of the peninsula and the U.S.S.R. taking over the area to the north of the 38th parallel. This division was meant to be temporary until the United States, U.K., Soviet Union, and China could arrange a trusteeship administration.
In December 1945, a conference was convened in Moscow to discuss the future of Korea. A five-year trusteeship was discussed, and a joint Soviet-American commission was established. The commission met intermittently in Seoul but deadlocked over the issue of establishing a national government. In September 1947, with no solution in sight, the United States submitted the Korean question to the UN General Assembly. Initial hopes for a unified, independent Korea quickly evaporated as the politics of the Cold War and domestic opposition to the trusteeship plan resulted in the 1948 establishment of two separate nations with diametrically opposed political, economic, and social systems. Elections were held in the South under UN observation, and on August 15, 1948, the Republic of Korea (R.O.K.) was established in the South. Syngman Rhee, a nationalist leader, became the Republic’s first president. On September 9, 1948, the North established the Democratic People’s Republic of Korea (D.P.R.K.) headed by then-Premier Kim Il-sung, who had been cultivated and supported by the U.S.S.R.
Korean War of 1950-53
Almost immediately after establishment of the D.P.R.K., guerrilla warfare, border clashes, and naval battles erupted between the two Koreas. North Korean forces launched a massive surprise attack and invaded South Korea on June 25, 1950. The United Nations, in accordance with the terms of its Charter, engaged in its first collective action and established the UN Command (UNC), to which 16 member nations sent troops and assistance. Next to South Korea, the United States contributed the largest contingent of
Historical Eras
The major periods of {country}’s history at a glance.
Ancient Kingdoms
100 BCE – 935
The Korean Peninsula was organized into the rival kingdoms of Koguryo, Paekche, and Shilla by the first century AD, with Koguryo dominating much of what is now North Korea and Manchuria. In 668 AD, the Shilla kingdom unified the peninsula under a single rule, blending Buddhist culture with a centralized aristocratic state. This era laid the linguistic, cultural, and ethnic foundations of Korean civilization.
Koryo & Choson Dynasties
935 – 1910
The Koryo dynasty (935–1392), from which the Western name 'Korea' derives, succeeded Shilla and endured Mongol occupation from 1231 into the early 14th century. The Yi clan's Choson dynasty replaced Koryo in 1392 and governed for over five centuries, adopting Confucian statecraft and resisting major Japanese invasions in 1592 and 1597. Korea's isolation in the 19th century earned it the title 'Hermit Kingdom' before Japanese imperial ambitions ended Korean sovereignty.
Japanese Colonial Rule
1910 – 1945
Japan annexed Korea in 1910 following victories in the Sino-Japanese and Russo-Japanese wars, establishing a colonial administration that suppressed Korean language, culture, and organized resistance. Tokyo exercised tight centralized control over the peninsula for 35 years, extracting resources and labor while systematically dismantling traditional Korean institutions. Japan's surrender in August 1945 ended colonial rule and immediately precipitated the division of Korea along the 38th parallel.
Division & Korean War
1945 – 1953
Following World War II, the USSR occupied the north while the United States administered the south, and Cold War deadlock prevented reunification. The Democratic People's Republic of Korea was proclaimed in 1948 under Kim Il-sung, with Soviet troops withdrawing thereafter. The Korean War (1950–1953) devastated the peninsula and ended in an armistice that cemented the division, leaving the DPRK heavily militarized and ideologically hardened.
Kim Il-sung Era
1953 – 1994
Kim Il-sung consolidated absolute power under the Juche ideology of self-reliance, directing rapid heavy industrialization through the 1960s while building one of the world's largest standing armies. The state enforced a cult of personality and rigid socialist command economy, increasingly isolating North Korea from the international community. Decades of mismanagement and resource diversion toward the military eroded living standards and made the country dependent on foreign food assistance.
Kim Jong-il & Nuclear Crisis
1994 – present
Kim Jong-il assumed power following his father's death in 1994, presiding over a catastrophic famine triggered by flooding and economic collapse that killed hundreds of thousands. The regime pursued an aggressive nuclear weapons program, repudiating a 1994 non-proliferation agreement in 2002 and declaring itself a nuclear-armed state in 2005, alarming the international community. Despite a landmark inter-Korean summit in 2000, North Korea remained one of the world's most isolated and militarized states.
