Korea in the context of Peninsula

Seoul, officially Seoul Special Metropolitan City, is both the capital and largest city of South Korea, and the largest city in the whole of Korea. The broader Seoul Metropolitan Area, encompassing Seoul, Gyeonggi Province and Incheon, emerged as the world's sixth largest metropolitan economy in 2022, behind New York, Tokyo, Los Angeles, Paris, and London, and hosts more than half of South Korea's population. Although Seoul's population peaked at over 10 million, it has gradually decreased since 2014, standing at about 9.6 million residents as of 2024. Seoul is the seat of the South Korean government.

Seoul's history traces back to 18 BC when it was founded by the people of Baekje, one of the Three Kingdoms of Korea. During the Joseon dynasty, Seoul was officially designated as the capital, surrounded by the Fortress Wall of Seoul. In the early 20th century, Seoul was occupied by the Empire of Japan, temporarily renamed "Keijō" ("Gyeongseong" in Korean). The Korean War brought fierce battles, with Seoul changing hands four times and leaving the city mostly in ruins. Nevertheless, the city has since undergone significant reconstruction and rapid urbanization.

Continental climates often have a significant annual variation in temperature (warm to hot summers and cold winters). They tend to occur in central and eastern parts of the three northern-tier continents (North America and Eurasia), typically in the middle latitudes (40 to 55 or 60 degrees north), often within large landmasses, where prevailing winds blow overland bringing some precipitation, and temperatures are not moderated by oceans.

Continental climates occur mostly in the Northern Hemisphere due to the large landmasses found there. Most of northern and northeastern China, northern Mongolia, most of Korea, central Afghanistan, parts of Kazakhstan and Kyrgyzstan, eastern and southeastern Europe, much of the Russian Federation south of the Arctic Circle, central and southeastern Canada, and the central and northeastern United States have this type of climate. Continentality is a measure of the degree to which a region experiences this type of climate.

The little owl (Athene noctua), also known as the owl of Athena or owl of Minerva, is a bird that inhabits much of the temperate and warmer parts of Europe, the Palearctic east to Korea, and North Africa. It was introduced into Britain at the end of the 19th century and into the South Island of New Zealand in the early 20th century.

This owl is a member of the typical or true owl family Strigidae, which contains most species of owl, the other grouping being the barn owls, Tytonidae. It is a small (approx. 22 cm long), cryptically coloured, mainly nocturnal species and is found in a range of habitats including farmland, woodland fringes, steppes and semi-deserts. It feeds on insects, earthworms, other invertebrates and small vertebrates. Males hold territories that they defend against intruders. This owl is a cavity nester, and a clutch of about four eggs is laid in spring. The female does the incubation and the male brings food to the nest, first for the female and later for the newly hatched young. As the chicks grow, both parents hunt and bring them food, and the chicks leave the nest at about seven weeks of age.

The Sinosphere, also known as the Chinese cultural sphere, East Asian cultural sphere, or the Sinic world, encompasses multiple countries in East Asia and Southeast Asia that were historically heavily influenced by Chinese culture. The Sinosphere comprises Greater China, Japan, Korea, Vietnam and historically the Ryukyuans. Other definitions may include the regions of modern-day Mongolia and Singapore, due either to historical Chinese influence or a contemporary overseas Chinese population. The Sinosphere is different from the Sinophone world, which indicates regions where the Chinese language is spoken.

Imperial China was a major regional power in Eastern Asia and exerted influence on tributary states and neighboring states, including Japan, Korea, and Vietnam. These interactions brought ideological and cultural influences rooted in Confucianism, Buddhism, and Taoism. The four cultures were ruled by their respective emperors under similar imperial systems, furthermore, the adoption of the Confucian-based imperial examination system deeply influenced the bureaucracy and social structure of Korea and Vietnam. Chinese inventions influenced, and were in turn influenced by, innovations of the other cultures in governance, philosophy, science, and the arts. Literary Chinese became the written lingua franca for bureaucracy and communications, and Chinese characters became locally adapted as kanji in Japan, hanja in Korea, and chữ Hán in Vietnam.

The division of Korea began at the end of World War II on 2 September 1945, with the establishment of a Soviet occupation zone and a US occupation zone. These zones developed into separate governments, named the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea), which fought a war from 1950 to 1953. Since then the division has continued.

By the early 20th century, both countries were one single nation: the Korean Empire. During World War II, the Allied leaders had already been considering the question of Korea's future following Japan's eventual surrender in the war. The leaders reached an understanding that Korea would be removed from Japanese control but would be placed under an international trusteeship until the Koreans would be deemed ready for self-rule. In the last days of the war, the United States proposed dividing the Korean peninsula into two occupation zones (a U.S. and Soviet one) with the 38th parallel as the dividing line. The Soviets accepted their proposal and agreed to divide Korea, which led to the declaration of General Order No. 1.

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 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. North Korea, like South Korea, claims to be the sole legitimate government of the Korean Peninsula and adjacent islands. 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 the Empire of 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, separate governments were formed in Korea: the socialist and Soviet-aligned Democratic People's Republic of Korea in the north, and the capitalist, 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), but no formal peace treaty has ever been signed. Post-war North Korea benefited greatly from economic aid and expertise provided by other Eastern Bloc countries. However, Kim Il Sung, North Korea's first leader, 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 fall 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, the DPRK formally abandoned efforts to reunify Korea.

South Korea, officially the Republic of Korea (ROK), is a country in East Asia. It constitutes the southern half of the Korean Peninsula and borders North Korea along the Korean Demilitarized Zone, with the Yellow Sea to the west and the Sea of Japan to the east. Like North Korea, South Korea claims to be the sole legitimate government of the entire peninsula and adjacent islands. It has a population of about 52 million, of which half live in the Seoul metropolitan area, the ninth most populous metropolitan area in the world; other major cities include Busan, Daegu, and Incheon.

The Korean Peninsula was inhabited as early as the Lower Paleolithic period. Its first kingdom was noted in Chinese records in the early seventh century BC. From the mid first century BC, various polities consolidated into the rival kingdoms of Goguryeo, Baekje, and Silla. The lattermost eventually unified most of the peninsula for the first time in the late seventh century AD, while Balhae succeeded Goguryeo in the north. The Goryeo dynasty (918–1392) achieved lasting unification and established the basis for the modern Korean identity. The subsequent Joseon dynasty (1392–1897) generated cultural, economic, and scientific achievements and also established isolationism starting from the mid-17th century. The succeeding Korean Empire (1897–1910) sought modernization and reform but was annexed in 1910 into the Empire of Japan. Japanese rule ended following Japan's surrender in World War II, after which Korea was divided into two zones: the Soviet-occupied northern zone and the United States-occupied southern zone. After negotiations on reunification failed, the southern zone became the Republic of Korea in August 1948, while the northern zone became the communist Democratic People's Republic of Korea the following month.

The Lower Paleolithic era on the Korean Peninsula and in Manchuria began roughly half a million years ago. The earliest known Korean pottery dates to around 8000 BC and the Neolithic period began thereafter, followed by the Bronze Age by 2000 BC, and the Iron Age around 700 BC. The Paleolithic people are likely not the direct ancestors of the present Korean people, but their direct ancestors are thought to be the Neolithic People of about 2000 BC.

According to the mythic account recounted in the Samguk yusa (1281), the Gojoseon kingdom was founded in northern Korea and southern Manchuria in 2333 BC. The first written historical record on Gojoseon can be found from the text Guanzi. The Jin state was formed in southern Korea by the 3rd century BC. In the late 2nd century BC, Gojoseon eventually fell to the Han dynasty of China, which led to succeeding warring states, the Proto–Three Kingdoms period.

Various nomadic empires, including the Xiongnu (3rd century BC–1st century AD), the Xianbei state (c. AD 93–234), the Rouran Khaganate (330–555), the First (552–603) and Second Turkic Khaganates (682–744) and others, ruled the area of present-day Mongolia. The Khitan people, who used a para-Mongolic language, founded an empire known as the Liao dynasty (916–1125), and ruled Mongolia and portions of North China, northern Korea, and the present-day Russian Far East.

In 1206, Genghis Khan was able to unite the Mongol tribes, forging them into a fighting force which went on to establish the largest contiguous empire in world history, the Mongol Empire (1206–1368). After the fragmentation of the Mongol Empire, Mongolia came to be ruled by the Yuan dynasty (1271–1368) based in Khanbaliq (modern Beijing) and administered as part of the Lingbei Province. Buddhism in Mongolia began with the Yuan emperors' conversion to and dissemination of Tibetan Buddhism.

The Philippines, officially known as the Republic of the Philippines, is an archipelagic country in Southeast Asia. Located in the western Pacific Ocean, it consists of 7,641 islands, with a total area of roughly 300,000 square kilometers, which are broadly categorized in three main geographical divisions from north to south: Luzon, Visayas, and Mindanao. With a population of over 112 million, it is the world's fourteenth-most-populous country.

The Philippines is bounded by the South China Sea to the west, the Philippine Sea to the east, and the Celebes Sea to the south. It shares maritime borders with Taiwan to the north, Japan and the Korean Peninsula to the northeast, Palau to the east and southeast, Indonesia to the south, Malaysia to the southwest, Vietnam to the west, and China to the northwest. It has diverse ethnicities and a rich culture. Manila is the country's capital, and its most populated city is Quezon City. Both are within Metro Manila.

Gyeonggi Province (Korean: 경기도; RR: Gyeonggi-do, Korean pronunciation: [kjʌ̹ŋ.ɡi.do̞]) is the most populous province in South Korea.

Seoul, the nation's largest city and capital, is in the heart of the area but has been separately administered as a provincial-level special city since 1946. Incheon, the nation's third-largest city, is on the coast of the province and has been similarly administered as a provincial-level metropolitan city since 1981. The three jurisdictions are collectively referred to as Sudogwon and cover 11,730 km (4,530 sq mi), with a combined population of over 26 million - amounting to over half (50.25%) of the entire population of South Korea, and a third of the population of the Korean peninsula at the 2020 census.

Paekche or Baekje (Korean: 백제; Hanja: 百濟; RR: Baekje; MR: Paekche; pronounced [pɛk̚.tɕ͈e]) was a Korean kingdom located in southwestern Korea from 18 BCE to 660 CE. It was one of the Three Kingdoms of Korea, together with Goguryeo and Silla. While the three kingdoms were in separate existence, Baekje had the highest population of approximately 3,800,000 people (760,000 households), which was much larger than that of Silla (850,000 people) and similar to that of Goguryeo (3,500,000 people).

Baekje was founded by Onjo, the third son of Goguryeo's founder Jumong and Soseono, at Wiryeseong (present-day southern Seoul). Baekje, like Goguryeo, claimed to succeed Buyeo, a state established in present-day Manchuria around the time of Gojoseon's fall.

Joseon (English: /ˈtʃoʊsʌn/ CHOH-sun; Korean: 조선; Hanja: 朝鮮; MR: Chosŏn; pronounced [tɕo.sʰʌn]; also romanized as Chosun), officially Great Joseon (대조선국; 大朝鮮國; [tʰɛ.dʑo.sʰʌn.ɡuk̚]), was a dynastic kingdom of Korea that existed for 505 years. It was founded by Taejo of Joseon in July 1392 and replaced by the Korean Empire in October 1897. The kingdom was founded after the overthrow of Goryeo in what is today the city of Kaesong. Early on, Korea was retitled and the capital was moved to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the rivers of Amnok and Tuman through the subjugation of the Jurchens.

Over the centuries, Joseon encouraged the entrenchment of Confucian ideals and doctrines in Korean society. Neo-Confucianism was installed as the new state's ideology. Buddhism was accordingly discouraged, and occasionally Buddhists faced persecution. Joseon consolidated its effective rule over the Korean peninsula and saw the height of classical Korean culture, trade, literature, and science and technology. The kingdom was severely weakened by failed Japanese invasions in 1592 and 1598, which were followed by invasions by the Later Jin dynasty in 1627 and the Qing dynasty in 1636–1637. The country pursued an increasingly harsh isolationist policy, becoming known as the "hermit kingdom" in Western literature. After the end of these invasions from Manchuria, Joseon experienced a nearly 200-year period of peace and prosperity, along with cultural and technological development. What power the kingdom recovered during its isolation waned as the 18th century came to a close. Faced with internal strife, power struggles, international pressure, and rebellions at home, the kingdom declined rapidly in the late 19th century.

Korean philosophy focuses on a totality of world view. Some aspects of Shamanism, Buddhism, and Neo-Confucianism were integrated into Korean philosophy. Traditional Korean thought has been influenced by a number of religious and philosophical thought-systems over the years. As the main influences on life in Korea, often Korean Shamanism, Korean Taoism, Korean Buddhism, Korean Confucianism and Silhak movements have shaped Korean life and thought. From 20th century, various Western philosophical thoughts have strongly influenced on Korean academia, politics, and daily life.

Emperor Wu of Han (156 – 29 March 87 BC), personal name Liu Che and courtesy name Tong, was the seventh emperor of the Han dynasty from 141 to 87 BC. His reign lasted 54 years – a record not broken until the reign of the Kangxi Emperor more than 1,800 years later – and remains the record for ethnic Han emperors. His reign resulted in a vast expansion of geopolitical influence for the Chinese civilization, and the development of a strong centralized state via governmental policies, economical reorganization and promotion of a hybrid Legalist–Confucian doctrine. In the field of historical social and cultural studies, Emperor Wu is known for his religious innovations and patronage of the poetic and musical arts, including the development of the Imperial Music Bureau into a prestigious entity. It was also during his reign that cultural contact with western Eurasia was greatly increased, directly and indirectly.

During his reign, Emperor Wu led the Han dynasty through its greatest territorial expansion. At its height, the Empire's borders spanned from the Fergana Valley in the west, to northern Korea in the east, and to northern Vietnam in the south. Emperor Wu successfully repelled the nomadic Xiongnu from systematically raiding northern China, and dispatched his envoy Zhang Qian into the Western Regions in 139 BC to seek an alliance with the Greater Yuezhi and Kangju, which resulted in further diplomatic missions to Central Asia. Although historical records do not describe him as being aware of Buddhism, emphasizing rather his interest in shamanism, the cultural exchanges that occurred as a consequence of these embassies suggest that he received Buddhist statues from Central Asia, as depicted in the murals found in the Mogao Caves.

Since the 19th century, the United States government has participated and interfered, both overtly and covertly, in the replacement of many foreign governments. In the latter half of the 19th century, the U.S. government initiated actions for regime change mainly in Latin America and the southwest Pacific, including the Spanish–American and Philippine–American wars. At the onset of the 20th century, the United States shaped or installed governments in many countries around the world, including neighbors Hawaii, Panama, Honduras, Nicaragua, Mexico, Haiti, and the Dominican Republic.

During World War II, the U.S. helped overthrow many Nazi German or Imperial Japanese puppet regimes. Examples include regimes in the Philippines, Korea, East China, and parts of Europe. United States forces, together with the United Kingdom and Soviet Union, were also instrumental in collapsing Adolf Hitler's government in Germany and deposing Benito Mussolini in Italy.

A Study of History is a 12-volume universal history by the British historian Arnold J. Toynbee, published from 1934 to 1961. It received enormous popular attention but according to historian Richard J. Evans, "enjoyed only a brief vogue before disappearing into the obscurity in which it has languished". Toynbee's goal was to trace the development and decay of 19 or 21 world civilizations in the historical record, applying his model to each of these civilizations, detailing the stages through which they all pass: genesis, growth, time of troubles, universal state, and disintegration.

The 19 (or 21) major civilizations, as Toynbee sees them, are: Egyptian, Andean, Sumerian, Babylonic, Hittite, Minoan, Indic, Hindu, Syriac, Hellenic, Western, Orthodox Christian (having two branches: the main or Byzantine body and the Russian branch), Far Eastern (having two branches: the main or Chinese body and the Japanese-Korean branch), Islamic (having two branches which later merged: Arabic and Iranic), Mayan, Mexican and Yucatec. Moreover, there are three "abortive civilizations" (Abortive Far Western Christian, Abortive Far Eastern Christian, Abortive Scandinavian) and five "arrested civilizations" (Polynesian, Eskimo, Nomadic, Ottoman, Spartan), for a total of 27 or 29.

Printing in East Asia originated in China, evolving from ink rubbings made on paper or cloth from texts on stone tablets, used during the sixth century. A type of printing called mechanical woodblock printing on paper started in China during the 7th century in the Tang dynasty. The practice of woodblock printing soon spread throughout East Asia. As recorded in 1088 by Shen Kuo in his Dream Pool Essays, the Chinese artisan Bi Sheng invented an early form of movable type using clay and wood pieces arranged and organized for written Chinese characters. The earliest printed paper money with movable metal type to print the identifying code of the money was made in 1161 during the Song dynasty. In 1193, a book documented instructions on how to use the copper movable type. The use of metal movable type spread to Korea by the 13th century during the Goryeo period, with the world's oldest surviving printed book using moveable metal type being from 1377 in Korea.

From the 17th century to the 19th century in Japan, woodblock prints called ukiyo-e were mass-produced, which influenced European Japonisme and the Impressionists. The printing press became known in East Asia by the 16th century but was not adopted. Centuries later, mechanical printing presses combining some European influences were adopted, but then was replaced with newer laser printing systems designed in the 20th and 21st centuries.
