Hangeul Proclamation Day in South Korea: Origin & History

• The Problem: Before the 15th century, the Korean language was written using complex classical Chinese characters (Hanja). Learning thousands of intricate characters required immense time and resources, meaning only the elite aristocrats were literate. The vast majority of common citizens could not read or write.

• The Invention: Driven by a desire to democratize literacy, King Sejong the Great and his royal assembly of scholars (the Hall of Worthies or Jiphyeonjeon) developed a purely phonetic alphabet in 1443.

• The Proclamation: In 1446, King Sejong officially published and promulgated the script under the document titled Hunminjeongeum, which translates to “The Correct Sounds for the Instruction of the People”.
