Quotation - "Hangul was promulgated by the fourth king of the Joseon Dynasty, Sejong the Great. … The project was completed in late December 1443 or January 1444, and described in 1446 in a document titled Hunmin Jeongeum ("The Proper Sounds for the Education of the People"), after which the alphabet itself was named. … Various speculations about the creation process were put to rest by the discovery in 1940 of the 1446 Hunmin Jeong-eum Haerye ("Hunmin Jeong-eum Explanation and Examples"). This document explains the design of the consonant letters according to articulatory phonetics and the vowel letters according to the principles of Yin and Yang and vowel harmony."
