Korea's alphabet, created by King Sejong in 1443 and announced in 1446 so ordinary people could read and write.
See it on the Korean History map →What happened
Before Hangul (한글), Koreans wrote in Chinese characters, which only the elite mastered. Sejong's Hunminjeongeum (훈민정음), 'Correct Sounds for Instructing the People,' had 28 letters; 24 are used today. Basic consonants picture the mouth and tongue making each sound; vowels combine a dot (heaven), a flat line (earth) and an upright line (person). Letters stack into syllable blocks. The 1446 Haerye ('explanations and examples') lays out the design. The elite kept writing Chinese; Hangul spread through women's letters, novels, and later missionary and nationalist printing.
Why it matters
It is one of very few scripts with a known creator and stated design logic, and it underlies Korea's near-universal literacy. South Korea marks Hangul Day on October 9.
How we know
The Hunminjeongeum Haerye, found in Andong in 1940 and listed by UNESCO in 1997, and the annals' entry for late 1443 announcing the new letters.
Still debated
The Haerye's mouth-shape explanation is accepted, but whether the Mongol 'Phags-pa script also inspired some letter shapes is debated.
Connections (5)
▸King Sejong the Great created Hangul (Hunminjeongeum)Well documented
The connection
Troubled that commoners could not read laws or write their grievances, Sejong designed a phonetic alphabet, announced in late 1443 and issued in 1446 as the Hunminjeongeum. His preface says he made 28 letters so everyone could learn them easily and use them daily.
When and how
1443–1446 in Hanyang (Seoul), worked out largely in private by Sejong, apparently with help from his children and a few scholars.
How we know
The annals say the king 'personally created' the 28 letters, and his preface opens the 1446 Haerye.
Debates and open questions
How much Sejong designed himself versus with helpers is debated; most scholars now credit him as the main creator.
▸Hall of Worthies (Jiphyeonjeon) may have helped devise Hangul (Hunminjeongeum)Debated
The connection
Hall of Worthies scholars, including Jeong In-ji, Seong Sam-mun and Sin Suk-ju, wrote the Haerye's explanations and examples and researched Chinese sound systems, even consulting an exiled Ming scholar in Liaodong. Whether they helped design the letters, or mainly explained and spread them, is the open question.
When and how
1443–1446 in Hanyang (Seoul); eight scholars led by Jeong In-ji wrote the Haerye; Sin Suk-ju and Seong Sam-mun made research trips to Liaodong.
How sure are we?
Their names appear in the Haerye's postface. But the annals credit the king alone, and the Hall's deputy head, Choe Man-ri, opposed the letters.
Debates and open questions
Older textbooks credited the Hall jointly; many scholars now see Sejong as designer and the Hall as editors and promoters. Opinions still differ.
▸Hangul (Hunminjeongeum) was resisted by many in Yangban aristocracy and the class orderWell documented
The connection
In 1444 Choe Man-ri and other Hall of Worthies scholars petitioned against the new letters, arguing that leaving Chinese characters would make Korea 'barbarian' and weaken learning. Most yangban kept writing in Chinese; Hangul, then commonly called eonmun ('vernacular script'), stayed secondary in official life until 1894.
When and how
Early 1444 in Hanyang (Seoul); Choe Man-ri and six other scholars signed; Sejong rebuked them and jailed them for a day.
How we know
The full text of Choe Man-ri's petition and Sejong's reply are in the Sejong sillok.
Debates and open questions
Resistance was not total: kings and yangban men used Hangul privately, especially writing to women. How widely it was read before 1900 is debated.
▸Hangul (Hunminjeongeum) was used throughout the newspaper of Independence ClubWell documented
The connection
Elites had long written in Classical Chinese and looked down on Hangul. The Independent, launched in April 1896 by Seo Jae-pil and closely tied to the Independence Club, printed its Korean pages entirely in Hangul and put spaces between words, so ordinary readers, including women, could follow the news.
When and how
Seoul, from April 7, 1896; Seo Jae-pil, with the young Hangul scholar Ju Si-gyeong working on the paper.
How we know
Surviving issues of The Independent; its first-issue date, April 7, is now Newspaper Day in South Korea.
Debates and open questions
How many people actually read it (circulation reached perhaps 3,000, each copy passed around) and how far it spread Hangul literacy beyond Seoul are uncertain.
▸Hangul (Hunminjeongeum) was pushed out of schools under Japanese colonial rule of KoreaWell documented
The connection
Colonial schools first taught Korean as a subject alongside Japanese. The 1938 education ordinance made Korean optional, and by the early 1940s it had vanished from classes; speaking it at school could bring punishment. In 1942 police arrested members of the Korean Language Society, who had standardized Hangul spelling in 1933 and were compiling a dictionary.
When and how
Korean schools from 1938, under Governor-General Minami Jiro; the Korean Language Society case began in October 1942, with members tried in Hamheung and two dying in prison.
How we know
Education ordinances of 1911, 1922, 1938 and 1943, school curricula, court records of the Language Society case, and memoirs of former students.
Debates and open questions
Colonial authorities also issued Hangul spelling rules, and Korean-language papers flourished in the 1920s–30s, so historians weigh late suppression against earlier tolerance.
