“A wise man can acquaint himself with them before the morning is over; a stupid man can learn them in the space of ten days.”
— Jeong Inji, scholar of the Joseon court, writing about Hangul in 1446
In the autumn of 1446, a royal proclamation changed the course of Korean history. King Sejong the Great of the Joseon dynasty officially promulgated a new writing system — one he had personally overseen the creation of — that would eventually become one of the most celebrated alphabets in the world. That system was Hangul, and its story is one of deliberate innovation, political courage, and a rare royal commitment to the everyday people of a kingdom.
Today, Hangul stands as the official writing system of both South Korea and North Korea. It is celebrated not only for its practical elegance but for the remarkable circumstances of its creation: a sitting monarch, in the fifteenth century, who decided that his people deserved a script of their own.

Why Did King Sejong Create Hangul?
To understand the significance of Hangul, it helps to understand what came before it. For centuries, educated Koreans wrote using Classical Chinese characters, known as Hanja. This was the language of scholarship, government, and the elite. But Classical Chinese bore little relationship to the spoken Korean language, and mastering it required years of intensive study — a luxury available only to aristocratic men of the ruling yangban class.
The vast majority of Joseon’s population — farmers, artisans, merchants, and women of all classes — were effectively locked out of literacy. They could not read royal proclamations, legal documents, or even basic written instructions. King Sejong, who ruled from 1418 to 1450, saw this as a profound injustice and a practical obstacle to good governance.
According to the preface of the Hunminjeongeum, the document that accompanied the new script’s release, Sejong stated directly that the people of Joseon had much they wished to express but lacked the means to do so in writing. His stated purpose was compassionate and clear: to give every person in his kingdom the ability to communicate their thoughts in written form.
It is worth noting that this motivation also had a political dimension. A more literate populace could better understand royal decrees and Confucian moral teachings — but whatever the mix of motives, the practical result was transformative.
The Science Behind the Script: How Hangul Was Designed
What makes Hangul extraordinary among the world’s writing systems is that it was consciously engineered. Most scripts evolved organically over centuries. Hangul was designed from first principles by Sejong and a group of royal scholars, likely working within the Hall of Worthies (Jiphyeonjeon), a royal research institute that Sejong had established earlier in his reign.
The consonant letters were designed to reflect the shape of the mouth, tongue, and throat when producing each sound. The letter for the sound “g” (ㄱ), for example, was said to represent the shape of the tongue pressing against the back of the throat. The letter for “n” (ㄴ) represents the tongue touching the upper palate. This featural design — where the visual form of a letter encodes phonetic information — is unique among the world’s major scripts and has fascinated linguists for generations.
The vowel letters were based on a philosophical framework drawn from traditional East Asian cosmology, representing heaven (a dot), earth (a horizontal line), and humanity (a vertical line). From these three basic elements, all ten primary vowel letters were constructed.
Rather than writing letters in a simple horizontal line as in the Latin alphabet, Hangul groups its letters into syllabic blocks. A single syllable is written as a cluster of two to four letters arranged into a square space, giving Korean text its distinctive visual rhythm. This system allows readers to identify syllable boundaries at a glance — a significant aid to reading speed and comprehension.
“Hangul is perhaps the most scientific writing system in the world — a script deliberately engineered to match the sounds of a language with a clarity and consistency that most alphabets never achieve.”

Opposition, Adoption, and the Long Road to Recognition
Sejong’s creation was not universally welcomed. Significant opposition came from conservative scholars and officials of the yangban class. The scholar Choe Manri led a faction that argued, in a formal petition to the king, that creating a new script separate from Chinese characters was culturally inappropriate and would distance Korea from the Chinese civilisational tradition that underpinned Joseon’s own legitimacy.
Sejong largely dismissed these objections and proceeded with the promulgation. Yet the resistance was not without lasting effect. For centuries after its introduction, Hangul was treated as a secondary script — used in vernacular literature, personal letters, and texts aimed at women and commoners, while Classical Chinese remained the language of officialdom and high culture. Elite men who wrote in Hangul sometimes risked social ridicule.
The script was known by various names over the centuries, including eonmun (vernacular writing). The name “Hangul” itself — meaning roughly “great script” or “Korean script” — was popularised only in the early twentieth century by the linguist and nationalist scholar Ju Sigyeong.
It was during the late nineteenth and early twentieth centuries that Hangul finally came into its own. As Korea confronted colonialism and modernisation, intellectuals and reformers embraced Hangul as a symbol of national identity. Under Japanese colonial rule (1910–1945), the Japanese administration attempted at various points to suppress the Korean language and script entirely. This repression had the paradoxical effect of intensifying Korean attachment to Hangul as an expression of cultural survival and resistance.
After liberation in 1945, Hangul was adopted as the sole official script of the newly independent Korean states. In South Korea, Hangul Day is celebrated on 9 October each year, marking the anniversary of the promulgation of the Hunminjeongeum in 1446.
3 Reasons Why Hangul Remains Remarkable Today
1. One of the Highest Literacy Rates in the World
South Korea consistently ranks among the world’s most literate nations, with literacy rates exceeding 97 percent. Linguists and education researchers frequently credit the logical simplicity of Hangul as a contributing factor. Unlike English, where spelling and pronunciation frequently diverge, or Chinese, which requires memorising thousands of individual characters, Hangul can be learned to a functional reading level by most adults in a matter of days or weeks.
2. A Rare Documented Origin
Most writing systems evolved over millennia, and their origins are reconstructed by scholars through archaeology and linguistic analysis. Hangul is one of the very few major writing systems in the world whose creator, date of creation, and design philosophy are all documented in historical records. The Hunminjeongeum manuscript, explaining both the letters and the reasoning behind them, survives to this day. The original text of the Hunminjeongeum Haerye — the explanatory commentary — was designated a UNESCO Memory of the World in 1997.
3. A Living Symbol of Korean Identity
Hangul is not merely a practical tool for communication. It carries enormous cultural weight as a symbol of Korean identity, ingenuity, and resilience. Its image appears on national monuments, currency, and public art. The story of its creation — a king who chose his people’s ability to read and write over the approval of his own court — continues to resonate as a founding narrative of Korean civilisation.
