King Sejong created Hangul so that ordinary people could easily read and write. This post explains why Hangul was created, the scientific principles behind its design, and how it developed into the writing system used today.
📌 What Is Hangul and Why Is It Easy to Learn?
- Hangul is the Korean writing system created by King Sejong in 1443 to help ordinary people read and write.
- It is considered one of the most scientific writing systems because its letters are based on how sounds are formed.
- Today, Hangul is easy to learn, and many learners can start reading Korean within a few hours.
If you are wondering what Hangul is or why it is considered one of the easiest writing systems in the world, the answer lies in its simple and logical design.
For beginners, this means you can start reading Korean much faster than you might expect, even without prior knowledge.
The Creator of Hangul – King Sejong
Hangul was created by King Sejong, the fourth ruler of the Joseon Dynasty. Before Hangul, Chinese characters were mainly used in Joseon, a system that was difficult for ordinary people to learn. King Sejong was deeply concerned that common people could not express their thoughts through writing, and in response, he designed a new writing system in 1443. It was officially proclaimed in 1446 under the name Hunminjeongeum.
Hunminjeongeum means “the correct sounds for instructing the people.” As the name suggests, the script had a clear and practical purpose—to serve the people. King Sejong led its creation, while scholars of the Hall of Worthies helped organize and refine the system.
King Sejong is remembered as a ruler who sought equality in language based on his deep care for the people. The creation of Hangul remains a highly original achievement in the history of writing systems, as it was designed for all members of society rather than a privileged few.
I also remember memorizing parts of Hunminjeongeum during high school for entrance exams. At the time, I did not think deeply about its meaning, but looking back, learning the background of a writing system created by a king for his people feels like a truly meaningful experience.
Many people ask, “Is Hangul really easy to learn?” The answer is yes, and its scientific design is the reason why.
Principles of Its Design
Hangul is not merely a writing system but one designed with a scientific structure that reflects both phonetic principles and philosophical concepts. The consonants were shaped after the forms of speech organs, while the vowels were based on the traditional East Asian philosophy of heaven (ㆍ), earth (ㅡ), and human (ㅣ).
For example, the consonant ‘ㄱ’ represents the shape of the tongue blocking the throat, while ‘ㅁ’ reflects the form of closed lips. In this way, Hangul visually represents how sounds are produced, making it a highly systematic writing system.
Even today, the principles behind Hangul’s creation are often cited by linguists as a representative example of scientific script design and continue to be the subject of ongoing research.
Hangul Through History
To understand why Hangul is still widely used today, it is important to look at how it survived and developed through history.
After its proclamation, Hunminjeongeum initially faced difficulty gaining widespread use within a society dominated by the elite and government officials. Chinese characters remained the primary script of official domains, making it challenging for the new writing system to take hold quickly. Nevertheless, Hangul gradually spread into everyday life under various names.
In the early twentieth century, linguists such as Ju Si-gyeong began using the term “Hangul” and actively promoted systematic research and dissemination. During the Japanese colonial period, the use of Hangul was restricted and suppressed, yet efforts to preserve the language continued among the people.
After Korea’s liberation, Hangul was adopted as the official writing system of South Korea and became the script used by the majority of the population. It continued to develop alongside rules for spelling, spacing, and foreign word transcription. In 1997, the Hunminjeongeum Haerye was registered as a UNESCO Memory of the World, and every year on October 9, South Korea commemorates Hangul Day to honor its value and legacy.
In South Korea, October 9 is observed as Hangul Day,
a national day that commemorates the creation and proclamation of Hangul.
Rather than a festive celebration, the day often serves
as a moment to reflect on the role of language in everyday life.
It highlights the original intention behind Hangul—to provide
ordinary people with access to reading and writing—
and reminds modern society of the value of clear,
inclusive communication.
As I worked on this article, I found myself reflecting on how long Hangul has been a part of our lives. While growing up, I naturally used slang and expressions unique to my generation, but today, language seems to change and fade more quickly than ever. I try to limit slang and abbreviations around my children, yet I often catch myself slipping into old habits.
In the past, I did not fully realize how meaningful it was to have our own unique writing system. Now, seeing people around the world learning Hangul highlights how its structure and value are being recognized beyond national borders.
The Korean drama Tree with Deep Roots presents the story of Hangul’s creation from a compelling perspective. By blending historical events with imagination, the series offers a deeper look into the challenges and decisions King Sejong faced while creating the script. The drama is available on major streaming platforms.
Did King Sejong ever imagine that the writing system he created would one day be used around the world? The fact that Hangul continues to thrive today speaks clearly to the significance of his choice.
