What Is the History of Hangul in Brief?
The history of Hangul is the story of a script that was invented quickly and adopted slowly. Five dates carry the whole story:
- 1443: King Sejong completes the 28-letter alphabet.
- 1446: the alphabet is promulgated with the book Hunminjeongeum (훈민정음, "the correct sounds for instructing the people").
- 1894: the Gabo reforms make Korean script the basis of government documents.
- 1933: the Korean Language Society publishes the Unified Hangul Spelling System, which still shapes modern spelling.
- 1948: South Korea's law on exclusive use of Hangul sets Hangul as the script for official documents.
If the title is new to you, read what the name Hunminjeongeum means first. The timeline below adds the events between these dates.
Hangul History Timeline: 1443 to Today
| Year | Event | Why it matters |
|---|---|---|
| 1443 | Sejong completes the alphabet (late in the 12th lunar month) | Creation date; the basis of North Korea's alphabet day |
| 1444 | Scholar Choe Malli petitions against the script | First recorded elite opposition |
| 1446 | Promulgation and the explanatory Haerye edition | Design principles written down; basis of the 9 October date |
| 1504 | King Yeonsangun restricts teaching and use of Hangul after anonymous Hangul posters criticise him | The best-known royal suppression |
| 1527 | Choe Sejin's Hunmong jahoe lists letter names close to today's | Origin of names such as 기역 and 니은 |
| 1894 | Gabo reform decree: Korean script as the basis of official documents | Hangul becomes official |
| c. 1912 | Linguist Ju Si-gyeong popularises the name 한글 | The script gets its modern name |
| 1926 | First celebration of Hangul Day, as Gagyanal | Start of the national commemoration |
| 1933 | Unified Hangul Spelling System | Modern spelling standard; obsolete letters dropped |
| 1940 | The Haerye copy is found in Andong | Design explanations confirmed |
| 1948 | Law on the exclusive use of Hangul | Hangul as the official script of South Korea |

The table shows a gap of more than 400 years between invention and official status, and the people behind the invention are the natural place to start.
Who Invented Hangul?
King Sejong (세종, reigned 1418–1450) invented Hangul, and records from his reign credit the script to the king himself. Scholars around him, especially those of the Hall of Worthies (집현전, Jiphyeonjeon), wrote the 1446 explanatory book and helped spread the script. How much each side contributed is a contested point: some historians stress Sejong's personal authorship, others give the scholars a larger role.
The short answer is King Sejong, but the full story of who invented Hangul and why includes the scholars around him.
Who Invented Hangul? Covers Sejong's motives, the Hall of Worthies, the 1444 opposition and the competing views on authorship.
How Was Hangul Designed?
Hangul was designed on two principles explained in the Hunminjeongeum Haerye: consonants picture the speech organs, and vowels combine three symbols for heaven (a dot), earth (a flat line) and human (an upright line). Extra strokes then mark stronger sounds, so ㄱ becomes ㅋ. This design makes Hangul a featural alphabet, a script whose letter shapes show features of sounds.
Read how the letters were designed from the shapes of the mouth and the ideas of heaven, earth and human.

How Did Koreans Write before Hangul?
Before Hangul, educated Koreans wrote Classical Chinese and used Chinese characters to represent Korean words and grammar in systems called idu, hyangchal and gugyeol. These systems needed years of character study, so reading and writing stayed with a small educated class.
To see why a new script was needed, start with how Korean was written before Hangul using Chinese characters.

From Restricted Script to Official Alphabet
Hangul spread for four centuries outside official writing, in letters, translated Buddhist and Confucian texts, popular novels and women's writing, while government and scholarship stayed in Chinese characters. It took more than 400 years to reach the moment when Hangul became the official script in 1894, followed by the spelling standard of 1933 and South Korea's 1948 law.
When Hangul Became Official Follows the script from Yeonsangun's 1504 restrictions to the Gabo reforms, the colonial period and the post-1945 script policies of both Koreas.
Hangul Day in South and North Korea
Koreans celebrate the alphabet every year on Hangul Day on 9 October in South Korea, the anniversary of the 1446 promulgation converted to the modern calendar. North Korea marks Chosŏn'gŭl Day on 15 January instead, a date linked to the creation of the script in 1443–1444.

The Four Letters Hangul Lost
The original set had 28 letters, including four letters that are no longer used: the vowel ㆍ (arae-a) and the consonants ㅿ, ㆆ and ㆁ. Sound changes made them unnecessary, and the 1933 spelling system dropped ㆍ, the last survivor, which leaves 24 basic letters today.

Where Should You Start Reading?
Start with the page that matches your goal:
- You want the core story in 10 minutes: read Who Invented Hangul?
- You are learning the letters: read How Hangul Was Designed, because the stroke families make 14 consonants easier to memorise.
- You are curious why Korea needed an alphabet: read How Korean Was Written Before Hangul.
- You are planning around 9 October: read Hangul Day.
- You saw a strange dot in an old sign: read Obsolete Hangul Letters.
Is the History Useful for Learning the Letters?
Yes, for one part in particular: the design history. Knowing that ㄱ pictures the tongue root and that ㅋ adds one stroke for a stronger sound turns memorisation into logic. The dates and politics are interesting context but do not help you read. Ready to use this history?

Writing in Korea over Time: Comparison
| Feature | Classical Chinese and idu | Mixed script (국한문 혼용) | Hangul only (한글 전용) |
|---|---|---|---|
| Main period | before 1446 to 1894 (official use) | 1894 to the late 20th century | late 20th century to today (South); from about 1949 (North) |
| Letters needed | thousands of characters | 24 letters plus common Hanja | 24 letters |
| Who could read it | a small educated class | readers with secondary schooling | almost everyone |
| Typical text | royal records, official documents | newspapers, laws, textbooks | today's books, signs, the internet |
| Example of "school" | 學校 | 學校 inside a Hangul sentence | 학교 |
Honest limit: this hub summarises; dates such as Ju Si-gyeong's first use of 한글 and North Korea's exact date basis are reported differently in different sources, and the child pages note those disagreements. The history of Hangul is still being researched, especially the authorship question. To start learning the letters themselves, return to the Korean alphabet hub.
Frequently Asked Questions
Is Hangul older than the English alphabet?
No. The Latin alphabet used for English is more than 2,500 years old and descends from older Greek and Phoenician scripts, while Hangul dates from 1443. Hangul is unusual for a different reason: it is one of very few scripts whose creator, date and design principles are recorded in a document from the time of its invention.
Why did Korean scholars oppose Hangul?
Many officials saw Classical Chinese as the language of learning and diplomacy. In 1444 the scholar Choe Malli submitted a memorial arguing that a separate script would separate Korea from Chinese civilisation and weaken scholarship. Elite writing stayed mostly in Chinese characters for centuries, while Hangul spread through letters, songs, religious texts and women's writing.
Where can you see the original Hunminjeongeum?
The surviving 1446 Haerye edition found in Andong in 1940 is held by the Kansong Art Museum in Seoul and is a designated National Treasure (listed as No. 70 before South Korea dropped heritage numbers in 2021). It is shown only occasionally. The National Hangeul Museum in Seoul displays facsimiles and explains the book's contents in its permanent exhibition.
Did Japan ban Hangul during the colonial period?
Japanese colonial rule (1910–1945) did not issue one single ban on Hangul, but it steadily restricted Korean. Korean-language teaching was cut back from 1938, major Korean newspapers were closed in 1940, and members of the Korean Language Society were arrested in 1942 while compiling a dictionary.
How long did it take for Hangul to replace Hanja?
About 500 years. Hangul was promulgated in 1446 but became the basis of official documents only in 1894. Newspapers and books used mixed Hangul and Hanja through most of the 20th century. Today South Korean everyday writing is almost entirely in Hangul, while North Korea dropped Hanja from general use around 1949.
