Secretly and Greatly

People agree that King Sejong, who was a great linguist himself, personally created Hangeul.

In addition to Hangeul being a very scientific and remarkable alphabet, it was also created in top secret so there have been various theories as to who created it. However, the historical records show repeatedly show that King Sejong directly created Hangeul. Many inventions and writings were created during King Sejong’s reign. Among all these achievements, the records specify he “personally” created Hangeul, and people agree that King Sejong, who was a great linguist himself, personally created Hangeul.

However, if we look into who helped King Sejong create Hangeul, we find that his sons were involved in the process. The crown prince, Prince Suyang and Prince Anpyeong were helped their father.

After creating Hangeul, Sejong had the books written in Chinese translated into Hangeul and distributed. Most of the people then were Buddhists, so King Sejong hoped to spread Hangeul by translating the Buddhist scriptures which most people were familiar with. In fact, it was King Sejong’s son Prince Suyang who was commanded to translate the Buddhist scriptures to Hangeul. The fact that the King’s own family was directly involved in creating Hangeul shows just how secretive the process was.
