Sejong the Great (세종대왕, Korean pronunciation: [se̞(ː)dzo̞ŋ de̞waŋ]; 15 May 1397 – 8 April 1450) was the fourth ruler of the Joseon Dynasty of Korea. He was the third son of King Taejong and Queen Wongyeong, and was designated as Crown Prince after his older brother, Grand Prince Yangnyeong, was stripped of his title. He ascended to the throne in 1418, but during the first four years of his reign, Taejong governed as regent and executed Sejong's father-in-law, Shim On, and his close associates.

Sejong reinforced Korean Confucian and Neo-Confucian policies, and enacted major legal amendments (공법; 貢法). He personally created and promulgated the Korean alphabet Hangul,[3][4] encouraged advancements of science and technology, and introduced measures to stimulate economic growth. He dispatched military campaigns to the north and instituted the Samin policy (사민정책; 徙民政策) to attract new settlers to the region. To the south, he helped subjugate Japanese pirates, during the Ōei Invasion. He is regarded as one of the greatest kings in the history of Korea.

After his father's death, he governed as the sole monarch from 1422 to 1450, although after 1439 he became increasingly ill,[5] and starting from 1442, his son, Crown Prince Yi Hyang (the future King Munjong), acted as regent.


Although the appellation "the Great" (대왕大王) was given posthumously to almost every ruler of Goryeo and Joseon, this title is usually associated with Gwanggaeto and Sejong.[citation needed]

Early life

Sejong was born as Yi Do on April 10, 1397,[6] with his birthday later adjusted to May 15, after Korea's adoption of the Gregorian calendar in 1896. 15 May is the officially recognized birthday of King Sejong, and is celebrated along with National Teachers Day in South Korea.[7]

Sejong was the third son of King Taejong.[8] When he was twelve, he became Grand Prince Chungnyeong (충녕대군). As a young prince, Sejong was favored by King Taejong over his two older brothers.

As the third son of Taejong, Sejong's ascension to the throne was unique. Taejong's eldest son, Yangnyeong (양녕대군), was named heir apparent in 1404. However, Yangnyeong's free spirited nature as well as his preference for hunting and leisure activities resulted in his removal from the position of heir apparent in June 1418. Though it is said that Yangnyeong abdicated in favor of his younger brother, there are no definitive records regarding Yangnyeong's removal. Taejong's second son Grand Prince Hyoryeong became a monk upon the elevation of his younger brother Sejong.[9]

Following the removal of Yangnyeong as heir apparent, Taejong moved quickly to secure his youngest son's position as heir apparent. The government was purged of officials who disagreed with the removal of Yangnyeong. In August 1418, Taejong abdicated in favour of Sejong. However, even in retirement Taejong continued to influence government policy. Sejong's surprising political skill and creativity did not become apparent until after Taejong's death in 1422.[9]

While making Hangul, Sejong slowly lost his sight. However, King Sejong continued to study and create Hangul, and until shortly before his death, he devoted himself to Hangul and passed away.



King Sejong reorganized the Korean government by appointing people from different social classes as civil servants.[citation needed] Furthermore, he performed official government events according to Confucianism, and he encouraged people to behave according to the teachings of Confucianism.[citation needed] As a result, Confucianism became the social norm of Korea at the time.[citation needed]

He suppressed Buddhism by banning outside Buddhist monks from entering Seoul and reduced the seven schools of Buddhism down to two, Seon and Gyo, drastically reducing the power and wealth of the Buddhist hierarchy.[10]

During the Goryeo dynasty, Buddhist monks wielded a strong influence in politics and the economy. With the dominant powers of the Joseon dynasty now being devout Confucianists who viewed Buddhism as a false philosophy, many officials accused the temples and monks of being corrupted by power and money. This strengthened the opposition to Buddhism within the Joseon government. One of the key factors to the suppression of Buddhism was Sejong's reform of the land system, where temple lands were seized and redistributed for development. Because of this, Buddhist temples and monks lost large amounts of economic influence and power.[11][12]

In 1427, Sejong also ordered a decree against the Huihui (Korean Muslim) community that had held special status and stipends since the Yuan dynasty. The Huihui were forced to abandon their headgear, to close down their "ceremonial hall" (mosque in the city of Kaesong) and worship like everyone else. No further mention of Muslims exist during the era of the Joseon.[13]

Economic Influence

In the early years of the Joseon Dynasty Korea's economy was based on a barter system with cloth, grain, and cotton being the most common forms of currency. In 1423 under King Sejong’s rule the government attempted to develop a national currency modeled off of the Chinese Kaiyuan Tongbao. The Joseon Dynasty’s Joseon Tongbo was a bronze coin, backed by a silver standard, with 150 coins being equal to 600 grams of silver. Production of the Joseon Tongbo ceased in 1425 as they were expensive to produce, with the exchange rate falling to less than the intrinsic value of the coin.[14]

He collaborated closely with the Chinese Ming Dynasty. In relationship with Jurchen people, he installed 10 military posts, 4 counties and 6 garrisons (hangul: 사군육진 hanja: 四郡六鎭), in the northern part of the Korean Peninsula.

He opened three ports to trade with Japan. However, he also launched the Ōei Invasion to crush Japanese pirates (Wokou) in the East China Sea.


King Sejong was an effective military planner. He created various military regulations to strengthen the safety of his kingdom,[15] supported the advancement of Korean military technology, including cannon development. Different kinds of mortars and fire arrows were tested as well as the use of gunpowder.[citation needed]

In May 1419, King Sejong, under the advice and guidance of his father Taejong, embarked upon the Gihae Eastern Expedition, the ultimate goal of this military expedition to remove the nuisance of Japanese pirates who had been operating out of Tsushima Island. During the expedition, 245 Japanese were killed, and another 110 were captured in combat, while 180 Korean soldiers were killed. 146 Chinese and 8 Korean kidnapped were liberated by this expedition. In September 1419 a truce was made and the Korean army returned to Korea, but the Treaty of Gyehae was signed in 1443, in which the Daimyo of Tsushima promised to pay tribute to the King of Joseon; in return, the Joseon court rewarded the Sō clan with preferential rights regarding trade between Japan and Korea.[16]

In 1433, Sejong sent Kim Jongseo (hangul: 김종서, hanja: 金宗瑞), a prominent general, north to destroy the Jurchens (later known as the Manchus). Kim's military campaign captured several castles, pushed north, and expanded Korean territory, to the Songhua River.[17][18][19] 4 counties and 6 garrisons were established to safeguard the people from the Jurchens.

Science, technology, and agriculture

In 1420 King Sejong's love for science lead him to create an institute within Gyeongbokgung palace known as the (집현전 Jade Hall) or Hall of Worthies. The institute was responsible for conducting scientific research with the purpose of advancing Korean technology. The Hall of Worthies was meant to be a collection of Korea's best and brightest thinkers, with the government offering grants and scholarships to encourage young scholars to attend.[20][21]

Sejong promoted the sciences.[22][23] He wanted to help farmers so he decided to create a farmer's handbook. The book—the Nongsa jikseol (hangul: 농사직설, hanja: 農事直說)—contained information about the different farming techniques that he told scientists to gather in different regions of Korea.[24] These techniques were needed in order to maintain the newly adopted methods of intensive, continuous cultivation in Korean agriculture.[24]

One of his close associates was the great Korean inventor Jang Yeong-sil (hangul: 장영실, hanja: 蔣英實). Jang was naturally a creative and smart thinker as a young person. Sejong noticed Jang's skill and immediately called him to his court in Seoul. Upon giving Jang a government position and funding for his inventions, officials protested, believing a person from the lower classes should not rise to power among nobles. Sejong instead believed Jang merited support because of his ability. Jang created new significant designs for water clocks, armillary spheres, and sundials.[25]

In 1442, Jang made one of the world's first standardized rain gauges named Cheugugi.[26] This model has not survived, since the oldest existing Korean rain gauge is one made in 1770, during the reign period of King Yeongjo. According to the Daily Records of the Royal Secretariat (hangul: 승정원일기;hanja: 承政院日記), King Yeongjo wanted to revive the glorious times of King Sejong the Great, and so read chronicles of Sejong's era. When he came across mention of a rain gauge, King Yeongjo ordered a reproduction. Since there is a mark of the Qing Dynasty ruler Qianlong (r. 1735–1796) of China, dated 1770,[27] this Korean-designed rain gauge is sometimes misunderstood as having been imported from China.

In 1434 Jang Yeong-sil tasked by King Sejong invented the Gabinja (갑인자, 甲寅字) printing press. The printing press was said to be twice as fast as the previous model and composed copper-zinc and lead-tin alloys.[28]

Sejong also wanted to reform the Korean calendar system, which was at the time based upon the longitude of the Chinese capital.[24] Sejong had his astronomers create a calendar with the Joseon capital of Seoul as the primary meridian.[24] This new system allowed Korean astronomers to accurately predict the timing of solar and lunar eclipses.[24][29]

In the realm of traditional Korean medicine, two important treatises were written during his reign. These were the Hyangyak jipseongbang and the Euibang yuchwi, which historian Kim Yongsik says represents "Koreans' efforts to develop their own system of medical knowledge, distinct from that of China."[24]


In 1426, Sejong the Great enacted a law that granted government nobi women 100 days of maternity leave after childbirth, which, in 1430, was lengthened by one month before childbirth. In 1434, Sejong also granted the husbands 30 days of paternity leave.[30]

In order to provide equality and fairness in taxation for the common people, Sejong the Great issued a royal decree to administer a nationwide public opinion poll regarding a new tax system called Gongbeop in 1430. Over the course of 5 months, the poll surveyed 172,806 people, of which approximately 57% responded with approval for the proposed reform.[31][32]

Sejong depended on the agricultural produce of Joseon's farmers, so he allowed them to pay more or less tax according to fluctuations of economic prosperity or hard times.[citation needed] Because of this, farmers could worry less about tax quotas and work instead at surviving and selling their crops. Once the palace had a significant surplus of food, King Sejong then distributed food to poor peasants or farmers who needed it.[citation needed]


In 1429 Nongsa-jikseol (hangul: 농사직설, hanja: 農事直說, "Explanations of Agriculture") was compiled. It was the first book about Korean farming, dealing with agricultural subjects such as planting, harvesting, and soil treatment.

Sejong was also a writer. He composed the famous Yongbi Eocheon Ga ("Songs of Flying Dragons", 1445), Seokbo Sangjeol ("Episodes from the Life of Buddha", July 1447), Worin Cheon-gang Jigok ("Songs of the Moon Shining on a Thousand Rivers", July 1447), and the reference Dongguk Jeong-un ("Dictionary of Proper Sino-Korean Pronunciation", September 1447).

Contributions to the Arts

One of Sejong’s closest friends and mentors was the 15th century Korean musician Bak Yeon. Together they composed over two hundred musical arrangements. Sejong’s independent musical compositions include the Chongdaeop (Great Achievements), Potaepyong (Preservation of Peace), Pongraeui (Phoenix), and Yominrak (A Joy to Share with the People). Yominrak continues to be a standard piece played by modern traditional Korean orchestras, while Chongdaeop and Potaepyong are played at memorial ceremonies honoring the Kings of the Joseon Dynasty today.[33]

In 1418 under the reign of King Sejong, Koreanscholars developed the (편경 編磬) Pyeongyeong, a lithophone modeled off of the Chinese Bianqing. The Pyeongyeong is a percussion instrument consisting of two rows of 8 pumice slabs hung on a decorative wooden frame with a 16-tone range and struck with an Ox Horn mallet. The Pyeongyeong was manufactured using pumice mined from the Kyonggi Province and used primarily for ceremonial rights.[34][35]

Hunmin Jeongeum Eonhae

King Sejong the Great profoundly affected Korean history with his personal creation and introduction of hangul, the native phonetic writing system for the Korean language.[4][36] Although it is widely assumed that King Sejong ordered the Hall of Worthies to invent Hangul, contemporary records such as the Veritable Records of King Sejong and Jeong Inji's preface to the Hunminjeongeum Haerye emphasize that he invented it himself.[37]

Before the creation of Hangul, people in Korea (known as Joseon at the time) primarily wrote using Classical Chinese alongside phonetic writing systems based on Chinese script that predated Hangul by hundreds of years, including idu, hyangchal, gugyeol, and gakpil.[38][39][40][41] However, due to the fundamental differences between the Korean and Chinese languages,[42] and the large number of characters that needed to be learned, there was much difficulty in learning how to write using Chinese characters for the lower classes, who often lacked the privilege of education. To assuage this problem, King Sejong created the unique alphabet known as Hangul to promote literacy among the common people.[43] His intention was to establish a cultural identity for Korea through its unique script.[citation needed]

Hangul was completed in 1443 and published in 1446 along with a 33-page manual titled Hunmin Jeong-eum, explaining what the letters are as well as the philosophical theories and motives behind them.[44] The Hunmin Jeong-eum purported that anyone could learn Hangul in a matter of days. People previously unfamiliar with Hangul can typically pronounce Korean script accurately after only a few hours of study.

King Sejong faced backlash from the noble class as many disapproved of the idea of a common language, with some openly opposing its creation. Many within the noble class believed that giving the peasants the ability to read and write would allow them to find and abuse loopholes within the law. Others felt that Hangul would threaten their families’ positions in court by creating a larger pool of civil servants. The Korean elite continued to use Chinese Hanja long after Sejong’s death in 1450.[45] Hangul was often treated with contempt by those in power and received criticism in the form of nicknames, including Eonmun (meaning Vulgar Script), Amkeul (meaning Woman’s Script), and Ahaekkeul (meaning Children’s Script).

Despite this, Hangul gained popularity among women and fiction writers. In 1504 the study and publication of Hangul was banned by King Yeonsangun.[46] The spread and preservation of Hangul can be largely attributed to three main factors, books published for women, its use by Buddhist monks,[47] and the introduction of Christianity in Korea in 1602.[48] Hangul was brought into the mainstream of Korean culture in the 16th century, due to a renaissance in Korean literature and poetry. Hangul continued to gain popularity well into the 17th century, and gained wider use after a period of Korean Nationalism in the 19th century. In 1849 Hangul was adopted as Korea’s national writing system, and saw its first use in official government documents. After the annexation of Korea by Japanese forces Hangul was outlawed again until the liberation of Korea in 1945.[49][50]

Sejong was blinded years later by diabetes complications that eventually took his life in 1450.[citation needed] He was buried at the Yeong Mausoleum (영릉; 英陵). His successor was his first son, Munjong. Sejong judged that his sickly son, Munjong, was unlikely to live long and on his deathbed asked the Hall of Worthies scholars to look after his young grandson, Danjong.[citation needed] As predicted, Munjong died two years after his succession, and political stability enjoyed under Sejong disintegrated when Danjong became the sixth king of Joseon at the age of twelve.[citation needed] Eventually, Sejong's second son, Sejo, usurped the throne from Danjong in 1455. When the six martyred ministers were implicated in a plot to restore Danjong to throne, Sejo abolished the Hall of Worthies, and executed Danjong and several ministers who served during Sejong's reign.[citation needed]

Statue and museum exhibit

Main article: Statue of King Sejong (Gwanghwamun)

A 9.5-meter-high (31 ft) bronze statue of King Sejong was placed in 2009 on a concrete pedestal on the boulevard of Gwanghwamun Square and directly in front of the Sejong Center for the Performing Arts in Seoul.[65] The sculptor was Kim Young-won.[66] The pedestal contains one of several entrances to the 3,200 square meter, underground museum exhibit entitled "The Story of King Sejong".[67][68] It was dedicated on Hangul Day in celebration of the 563rd anniversary of the invention of the Korean alphabet by King Sejong.[69]

Namesake from Sejong

The street Sejongno and the Sejong Centre for the Performing Arts, both located in central Seoul, are named after King Sejong.[70]

In early 2007, the Republic of Korea government decided to create a special administrative district from part of the present South Chungcheong Province, near what is presently Daejeon. The district was named Sejong Special Autonomous City.
