Hanja in the context of Korean language

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.

Traditional Chinese characters are a standard set of Chinese character forms used to write Chinese languages. In Taiwan, the set of traditional characters is regulated by the Ministry of Education and standardized in the Standard Form of National Characters. These forms were predominant in written Chinese until the middle of the 20th century, when various countries that use Chinese characters began standardizing simplified sets of characters, often with characters that existed before as well-known variants of the predominant forms.

Simplified characters as codified by the People's Republic of China are predominantly used in mainland China, Malaysia, and Singapore. "Traditional" as such is a retronym applied to non-simplified character sets in the wake of widespread use of simplified characters. Traditional characters are commonly used in Taiwan, Hong Kong, and Macau, as well as in most overseas Chinese communities outside of Southeast Asia. As for non-Chinese languages written using Chinese characters, Japanese kanji include many simplified characters known as shinjitai standardized after World War II, sometimes distinct from their simplified Chinese counterparts. Korean hanja, still used to a certain extent in South Korea, remain virtually identical to traditional characters, with variations between the two forms largely stylistic.

The Yellow Sea (simplified Chinese: 黄海; traditional Chinese: 黃海; pinyin: Huáng Hǎi; Korean: 황해; Hanja: 黃海; RR: Hwanghae), also known as the North Sea, is a marginal sea of the Western Pacific Ocean located between mainland China and the Korean Peninsula, and can be considered the northwestern part of the East China Sea.

Jeju Island (Jeju and Korean: 제주도; Hanja: 濟州島; RR: Jejudo; pronounced [tɕeːdʑudo]) is South Korea's largest island, covering an area of 1,833.2 km (707.8 sq mi), which is 1.83% of the total area of the country. Alongside outlying islands, it is part of Jeju Province and makes up the majority of the province.

The island lies in the Korea Strait, 82.8 km (51.4 mi) south of the nearest point on the Korean Peninsula. The Jeju people are indigenous to the island, and it has been populated by modern humans since the early Neolithic period. The Jeju language is considered critically endangered by UNESCO. It is also one of the regions of Korea where Shamanism is most intact.

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 court music (Korean: 궁중음악; Hanja: 宮中音樂) comprises three main musical genres: aak, an imported form of Chinese ritual music; a pure Korean form called hyangak; and a combination of Chinese and Korean styles called dangak.

Korean court music and its historical origins can be traced back to the Three Kingdoms Period (57 BCE–668), the Unified Silla (668–935), Goryeo (918–1392) and Joseon dynasties (1392–1910). It was partly modelled on the court music of China, known as yayue. Korean court music also shows similarities with the court music of Japan, known as gagaku and of Vietnam, known as nhã nhạc, which also are also derivative of yayue.

The Chinese family of scripts includes writing systems used to write various East Asian languages, that ultimately descend from the oracle bone script invented in the Yellow River valley during the Shang dynasty. These include written Chinese itself, as well as adaptations of it for other languages, such as Japanese kanji, Korean hanja, Vietnamese chữ Hán and chữ Nôm, Zhuang sawndip, and Bai bowen. More divergent are the Tangut script, Khitan large script, Khitan small script and its offspring, the Jurchen script, as well as the Yi script, Sui script, and Geba syllabary, which were inspired by written Chinese but not descended directly from it. While written Chinese and many of its descendant scripts are logographic, others are phonetic, including the kana, Nüshu, and Lisu syllabaries, as well as the bopomofo semi-syllabary.

These scripts are written in various styles, principally seal script, clerical script, regular script, semi-cursive script, and cursive script. Adaptations range from the conservative, as in Korean, which used Chinese characters in their standard form with only a few local coinages, and relatively conservative Japanese, which has coined a few hundred new characters and used traditional character forms until the mid-20th century, to the extensive adaptations of Zhuang and Vietnamese, each coining over 10,000 new characters by Chinese formation principles, to the highly divergent Tangut script, which formed over 5,000 new characters by its own principles.

Koreanic is a compact language family consisting of the Korean and Jeju languages. The latter is often described as a dialect of Korean but is mutually unintelligible with mainland Korean varieties. Alexander Vovin has also suggested that the Yukjin dialect of the far northeast should be similarly distinguished.

Korean has been richly documented since the introduction of the Hangul alphabet in the 15th century. Earlier renditions of Korean using Chinese characters, however, are much more difficult to interpret.

A circuit (Chinese: 道; pinyin: dào or Chinese: 路; pinyin: lù) was a historical political division of China and is a historical and modern administrative unit in Japan. The primary level of administrative division of Korea under the Joseon and in modern North and South Korea employs the same Chinese character as the Chinese and Japanese divisions but, because of its relatively greater importance, is usually translated as province instead.

Pyongyang (Korean: 평양; Hancha: 平壤) is the capital and largest city of North Korea. Pyongyang is located on the Taedong River about 109 km (68 mi) upstream from its mouth on the Yellow Sea. According to the 2008 population census, it has a population of 3,255,288. Pyongyang is a directly administered city (직할시; 直轄市; chikhalsi) with a status equal to that of the North Korean provinces.

Pyongyang is one of the oldest cities in Korea. It was the capital of two ancient Korean kingdoms, Gojoseon and Goguryeo, and served as the secondary capital of Goryeo. Following the establishment of North Korea in 1948, Pyongyang became its de facto capital. The city was again devastated during the Korean War, but was quickly rebuilt after the war with Soviet assistance.

Old Chosŏn, also known as Gojoseon (Korean: 고조선; Hanja: 古朝鮮; RR: Gojoseon; MR: Kojosŏn) and its contemporary name Joseon (Korean: 조선; Hanja: 朝鮮; RR: Joseon; MR: Chosŏn), was the first kingdom on the Korean Peninsula. According to Korean mythology, the kingdom was established by the legendary king Tan'gun. Old Chosŏn possessed the most advanced culture in the Korean Peninsula at the time and was an important marker in the progression towards the more centralized states of later periods. The addition of Go (고; 古), meaning "old" or "ancient", is used in historiography to distinguish the kingdom from the Joseon dynasty, founded in 1392 CE.

According to the Memorabilia of the Three Kingdoms, Old Chosŏn was established in 2333 BCE by Tan'gun, who was said to be born from the heavenly prince Hwanung and a bear-woman, Ungnyeo. While Tan'gun is a mythological figure of whose existence no concrete evidence has been found, some interpret his legend as reflections of the sociocultural situations involving the kingdom's early development. Regardless, the account of Tan'gun has played an important role in the development of Korean identity. Today, the founding date of Old Chosŏn is officially celebrated as National Foundation Day in North and South Korea.

Goryeo (Korean: 고려; Hanja: 高麗; MR: Koryŏ; pronounced [ko.ɾjʌ]; Middle Korean: 고ᇢ롕〮, romanized: kwòwlyéy) was a Korean state founded in 918, during a time of national division called the Later Three Kingdoms period, that unified and ruled the Korean Peninsula until the establishment of Joseon in 1392. Goryeo achieved what has been called a "true national unification" by Korean historians as it not only unified the Later Three Kingdoms but also incorporated much of the ruling class of the northern kingdom of Balhae, who had origins in Goguryeo of the earlier Three Kingdoms of Korea. According to Korean historians, it was during the Goryeo period that the individual identities of Goguryeo, Baekje and Silla were successfully merged into a single entity that became the basis of the modern-day Korean identity. The name "Korea" is derived from the name of Goryeo, also romanized as Koryŏ, which was first used in the early 5th century by Goguryeo; Goryeo was a successor state to Later Goguryeo and Goguryeo.

Goryeo was established in 918 when general Wang Kŏn, after rising under the erratic Taebong ruler Kung Ye, was chosen by fellow generals to replace him and restore stability. Throughout its existence, Goryeo, alongside Unified Silla, was known to be the "Golden Age of Buddhism" in Korea. As the state religion, Buddhism achieved its highest level of influence in Korean history, with 70 temples in the capital alone in the 11th century. Commerce flourished in Goryeo, with merchants coming from as far as the Middle East. The capital in modern-day Kaesong, North Korea was a center of trade and industry. Goryeo was a period of great achievements in Korean art and culture.

The Korean Armistice Agreement (Korean: 한국정전협정; Hanja: 韓國停戰協定) is an armistice that brought about a cessation of hostilities of the Korean War. It was signed by United States Army Lieutenant General William Harrison Jr. and General Mark W. Clark representing the United Nations Command (UNC), North Korea leader Kim Il Sung and General Nam Il representing the Korean People's Army (KPA), and Peng Dehuai representing the Chinese People's Volunteer Army (PVA). The armistice was signed on 27 July 1953, and was designed to "ensure a complete cessation of hostilities and of all acts of armed force in Korea until a final peaceful settlement is achieved."

During the 1954 Geneva Conference in Switzerland, Chinese Premier and foreign minister Zhou Enlai suggested that a peace treaty should be implemented on the Korean peninsula. However, the US secretary of state, John Foster Dulles, did not accommodate this attempt to achieve such a treaty. A final peace settlement has never been achieved. The signed armistice established the Korean Demilitarized Zone (DMZ), the de facto new border between the two nations, put into force a ceasefire, and finalized repatriation of prisoners of war. The DMZ runs close to the 38th parallel and has separated North and South Korea since the Korean Armistice Agreement was signed in 1953.

The following is a list of major islands of South Korea, the Republic of Korea, arranged by body of water and then by province.

South Korea is mostly surrounded by water and has 2,413 kilometres (1,499 mi) of coast line along three seas; to the west is the Yellow Sea (called Sohae Korean: 서해; Hanja: 西海; in South Korea, literally means west sea), to the south is the East China Sea, and to the east is the East Sea (Sea of Japan) (called Donghae Korean: 동해; Hanja: 東海; in South Korea, literally means east sea). Geographically, South Korea's landmass is approximately 100,032 square kilometres (38,623 sq mi).
