Hangul supremacy
Hangul supremacy is the belief, most widespread in Korea, that the Hangul alphabet developed by King Sejong the Great's Hall of Worthies in 1443 is the simplest, most logical, most beautiful and most scientific of the world's writing systems. In its extreme form, the belief holds that Hangul is in fact best suited for the expression of sounds in all languages.
Origin of Hangul
Various fanciful speculations about the creation of Hangul were put to rest by the discovery in 1940 of the 1446 "Hunmin jeong-eum haerye" "Explanation of the "Hunmin Jeong-eum" with Examples". This document explains the design of the consonant letters according to articulatory phonetics and the vowel letters according to Confucian principles such as the "yin" and "yang" of vowel harmony (see below).
