North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korean Peninsula and borders China and Russia to the north at the Yalu (Amnok) and Tumen rivers, and South Korea (officially the Republic of Korea) to the south at the Korean Demilitarized Zone (DMZ). The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. Pyongyang is the capital and largest city.
The Korean Peninsula was first inhabited as early as the Lower Paleolithic period. Its first kingdom was noted in Chinese records in the early 7th century BCE. Following the unification of the Three Kingdoms of Korea into Silla and Balhae in the late 7th century, Korea was ruled by the Goryeo dynasty (918–1392) and the Joseon dynasty (1392–1897). The succeeding Korean Empire (1897–1910) was annexed in 1910 into Japan. In 1945, after the Japanese surrender at the end of World War II, Korea was divided into two zones along the 38th parallel, with the north occupied by the Soviet Union and the south occupied by the United States.
In 1948, two separate governments were formed in Korea: the Soviet-aligned Democratic People's Republic of Korea in the north, and the Western-aligned Republic of Korea in the south. The North Korean invasion of South Korea in 1950 started the Korean War. In 1953, the Korean Armistice Agreement brought about a ceasefire and established a demilitarized zone (DMZ). Kim Il Sung, North Korea's first leader, consolidated power and promoted his personal philosophy of Juche as the state ideology. Pyongyang's international isolation sharply accelerated from the 1980s onwards as the Cold War came to an end. The dissolution of the Soviet Union in 1991 then brought about a sharp decline to the North Korean economy. From 1994 to 1998, North Korea suffered a famine with the population continuing to suffer from malnutrition. In 2024, North Korea formally abandoned efforts to reunify Korea and designated South Korea as a separate, hostile state.
North Korea is a totalitarian hereditary dictatorship with a comprehensive cult of personality around the Kim family. Amnesty International considers the country to have the worst human rights record in the world. Officially, North Korea is a communist state, and describes itself as a socialist state which holds democratic elections. However, outside observers have described the elections as unfair, uncompetitive, and pre-determined. The Workers' Party of Korea (WPK) is the sole ruling party of North Korea, while Kimilsungism–Kimjongilism is the official ideology. The means of production are owned by the state through state-run enterprises and collectivized farms. Most services—such as healthcare, education, housing, and food production—are subsidized or state-funded.
North Korea is highly militarized, prioritizing the Korean People's Army in the allocation of resources. It possesses nuclear weapons. Its active-duty army of 1.28 million soldiers is the fourth-largest in the world. In addition to being a member of the United Nations since 1991, North Korea is also a member of the Non-Aligned Movement, the G77, and the ASEAN Regional Forum.
The modern spelling of Korea first appeared in 1671 in the travel writings of Hendrick Hamel, a sailor of the Dutch East India Company.
After the division of the country into North and South Korea, the two sides used different terms to refer to Korea: Chosŏn (조선) in North Korea, and Hanguk (한국) in South Korea. In 1948, North Korea adopted Democratic People's Republic of Korea (조선민주주의인민공화국; 朝鮮民主主義人民共和國; Chosŏnminjujuŭiinmin'gonghwaguk; ) as its official name. According to Daily NK, the country's official name is frequently shortened to just "the Republic" (공화국; 共和國; Konghwaguk) within North Korea.
In the wider world, because its government controls the northern part of the Korean Peninsula, it is commonly called North Korea to distinguish it from South Korea, which is officially called the Republic of Korea in English. Both governments historically considered themselves to be the legitimate government of the whole of Korea; for this reason, the people of North Korea consider themselves Koreans, not North Koreans, with foreign visitors being discouraged from using the latter term.
In the late 19th century, Korea came under the influence of Japan, which had become a significant regional power after winning the First Sino-Japanese War against Qing China and the Russo-Japanese War against the Russian Empire. Japan compelled Korea to become its protectorate in 1905 and formally annexed it in 1910. What followed was a period of forced assimilation, in which Korean language, culture, and history were suppressed. This led to the March First Movement protests in 1919 and the subsequent foundation of resistance groups in exile, primarily in China. Among the resistance groups was Provisional Government of the Republic of Korea. During the Japanese colonial period, most Koreans were peasants engaged in subsistence farming. In the 1930s, Japan developed mines, hydro-electric dams, steel mills, and manufacturing plants in northern Korea and neighboring Manchuria. The Korean industrial working class expanded rapidly, and many Koreans went to work in Manchuria. As a result, 65% of Korea's heavy industry was located in the north, but, due to the rugged terrain, only 37% of its agriculture. A Korean guerrilla movement emerged in the mountainous interior and in Manchuria, harassing the Japanese imperial authorities. One of the most prominent guerrilla leaders was the Communist Kim Il Sung.
Joint US-Soviet occupation and Division of Korea
After the Japanese surrender at the end of World War II in 1945, the Korean Peninsula was divided into two occupation zones along the 38th parallel, with the northern half of the peninsula occupied by the Soviet Union and the southern half by the United States. Negotiations on reunification failed. Soviet general Terentii Shtykov recommended the establishment of the Soviet Civil Administration in October 1945, and supported Kim Il Sung as chairman of the Provisional People's Committee of North Korea, established in February 1946. In September 1946, South Korean citizens rose up against the Allied Military Government. In April 1948, an uprising of the Jeju islanders was violently crushed. The South declared its statehood in May 1948 and two months later the ardent anti-communist Syngman Rhee became its ruler. The Democratic People's Republic of Korea was established in the North on 10 July 1948. Shtykov served as the first Soviet ambassador, while Kim Il Sung became premier.
Soviet forces withdrew from the North in 1948, and most American forces withdrew from the South in 1949. Ambassador Shtykov suspected Rhee was planning to invade the North and was sympathetic to Kim's goal of Korean unification under socialism. The two successfully lobbied Soviet leader Joseph Stalin to support a quick war against the South, which culminated in the outbreak of the Korean War.
The military of North Korea invaded the South on 25 June 1950, and swiftly overran most of the country. The United Nations Command (UNC) was subsequently established following the UN Security Council's recognition of North Korean aggression against South Korea. The motion passed because the Soviet Union, a close ally of North Korea and a member of the UN Security Council, was boycotting the UN over its recognition of the Republic of China rather than the People's Republic of China. The UNC, led by the United States, intervened to defend the South, and rapidly advanced into North Korea. As they neared the border with China, Chinese forces intervened on behalf of North Korea, shifting the balance of the war again. Fighting ended on 27 July 1953, with an armistice that approximately restored the original boundaries between North and South Korea, but no peace treaty was signed. Approximately 3 million people died in the Korean War, with a higher proportional civilian death toll than World War II or the Vietnam War. In both per capita and absolute terms, North Korea was the country most devastated by the war, which resulted in the death of an estimated 12–15% of the North Korean population (c. 10 million), "a figure close to or surpassing the proportion of Soviet citizens killed in World War II", according to Charles K. Armstrong. As a result of the war, almost every substantial building in North Korea was destroyed. Some have referred to the conflict as a civil war, with other factors involved.
