Hunminjeongeum

Hunminjeongeum (lit. The Correct/Proper Sounds for the Instruction of the People) is a document describing an entirely new and native script for the Korean language. The script was initially named after the publication, but later came to be known as hangul. It was created so that the common people illiterate in hanja could accurately and easily read and write the Korean language. Its supposed publication date, October 9, 1446, is now Hangul Day in South Korea.
