Korea is a peninsula in Northeast Asia with a continuous cultural region centered on the Korean language and a history shaped by dynasties, kingdoms, colonialism, war and division. The region produced states such as Gojoseon, Goguryeo, Baekje, Silla, Goryeo and Joseon, and in modern times comprises the Republic of Korea and the Democratic People's Republic of Korea. Korea's strategic location between China and Japan made it a crossroads for continental and maritime interactions involving Tang dynasty, Yuan dynasty, Mongol Empire, Jurchen people, Kitan and later Qing dynasty contacts.

Etymology and Names

The name derives from Goryeo (also spelled Koryo), the successor of Goguryeo and Silla political traditions; Western usage spread via travelers and cartographers encountering Goryeo envoys during the Mongol invasions of Korea and Marco Polo's accounts. Alternative endonyms include terms used in historical texts such as Samguk Sagi and Samguk Yusa, while modern states use Daehan Minguk and Chosŏn Minjujuŭi Inmin Konghwaguk in their formal titles. Colonial-era documents in Meiji period Japan and treaties like the Treaty of Portsmouth influenced external naming conventions, and nineteenth-century Western publications referencing Joseon dynasty also shaped toponyms.

Early history centers on archaeological cultures linked to Gojoseon and the bronze-iron transition noted in sites associated with Yemaek and the Mumun pottery period. The Three Kingdoms era—Goguryeo, Baekje and Silla—engaged in alliances and conflicts with Tang dynasty forces and engaged diplomatically with Ancient Japan through exchanges noted in Nihon Shoki. The later Goryeo dynasty standardized civil institutions, commissioned the Tripitaka Koreana and resisted Mongol invasions of Korea before forming a vassal relationship under the Yuan dynasty. Joseon dynasty established Neo-Confucian orthodoxy, produced the Hunminjeongeum script promulgated under Sejong the Great, and faced invasions such as the Japanese invasions of Korea (1592–1598) and the Later Jin–Joseon conflicts.

The nineteenth and twentieth centuries saw pressure from Russian Empire, Empire of Japan and Western powers leading to the Japan–Korea Treaty of 1910 and colonial rule under Empire of Japan. Resistance movements included figures linked to the March 1st Movement and governments-in-exile like the Provisional Government of the Republic of Korea. World War II outcomes and the Yalta Conference shaped postwar arrangements, culminating in the Korean War following 1948 Democratic People's Republic of Korea establishment and 1948 Republic of Korea proclamations. Subsequent decades featured the April Revolution, May 16 coup d'état, Gwangju Uprising, Sunshine Policy, and inter-Korean events including the Inter-Korean Summit (2000) and Panmunjom Declaration.

The peninsula extends between the Yellow Sea and the Sea of Japan (called East Sea in regional usage) and connects to the Asian continent via the Korean Peninsula isthmus into Manchuria. Major mountain ranges include the Taebaek Mountains and Sobaek Mountains, with peaks such as Baekdu Mountain (Mount Paektu) and Jirisan. Rivers like the Han River, Taedong River and Nakdong River shaped settlement and agriculture; island groups include Jeju Island and Geoje. Biodiversity hotspots host species like the Korean goral and Siberian tiger historically, while conservation areas include Hallasan National Park and Demilitarized Zone habitats noted for unique ecology. Environmental challenges have involved Yellow dust, industrial pollution linked to Pusan and Incheon ports, river management projects like the Four Major Rivers Project, and transboundary air quality negotiations with China and Russia.

Population centers concentrate in the Seoul Capital Area, Busan Metropolitan City, Daegu and Incheon. Ethnolinguistically the majority speak the Korean language with regional dialects such as Gyeongsang dialect, Jeolla dialect and Pyongan dialect; minority groups include Joseonjok and Korean diaspora communities in United States, Japan (the Zainichi Koreans), Russia and Central Asia. Religious affiliations feature Korean Confucianism, Seon Buddhism, Roman Catholicism, Korean Protestantism, and indigenous practices such as Korean shamanism. Major social movements have been centered on labor unions like the Korean Confederation of Trade Unions and student activism exemplified by events at Seoul National University and Yonsei University.

Korean culture produced classical literature like Samguk Yusa and The Tale of Hong Gildong, artistic traditions including Goryeo celadon, Joseon white porcelain and minhwa folk painting; performing arts include pansori, talchum mask dance and court music such as aak. The Hangul alphabet, created under Sejong the Great, transformed literacy and is used across media including ksl, Hangeul Day celebrations and modern publishing from houses like Munhakdongne Publishing Group. Contemporary cultural exports—K-pop acts like BTS (band), Blackpink and film directors such as Bong Joon-ho—have global impact through festivals like the Busan International Film Festival and awards including the Palme d'Or and Academy Awards. Culinary traditions feature kimchi, bibimbap, bulgogi, tea culture linked to Joseon dynasty literati and tea houses in Insadong.

Industrialization accelerated under postwar plans that created chaebol conglomerates including Samsung, Hyundai, LG Corporation, SK Group and POSCO driving exports in electronics, shipbuilding and automobiles. Financial centers include Seoul Finance Center and markets such as Korea Exchange in Yeouido, while logistics hubs involve Busan Port and Incheon International Airport. Agricultural regions on the western plains focus on rice cultivation, and energy portfolios involve Korea Hydro & Nuclear Power projects and fuel imports via routes through the Yellow Sea. Technology clusters like Daedeok Innopolis support research institutions such as KAIST, Korea University, Seoul National University and Yonsei University, and startups benefit from programs by agencies including the Korea Development Institute.

Political systems diverged after 1945 into the Republic of Korea with a presidential system, multiple parties such as the Democratic Party of Korea and People Power Party (South Korea), and the Democratic People's Republic of Korea with the Workers' Party of Korea and leadership under the Kim dynasty (North Korea). Cold War geopolitics involved the United States and Soviet Union; later diplomacy featured negotiations with United Nations Command, multilateral talks like the Six-Party Talks, and bilateral summits with United States–South Korea relations and Japan–South Korea relations. Security dynamics revolve around incidents such as the Cheonan sinking and Yeonpyeong bombardment, arms control efforts including the Agreed Framework (1994) and inter-Korean agreements like the Kaesong Industrial Region projects and the Sunshine Policy era initiatives.
