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.
History of Korea
In 1392, General Yi Seong-gye established the Joseon dynasty (1392–1910) after a coup d'état that overthrew the Goryeo dynasty in 1388. King Sejong the Great (1418–1450) implemented numerous administrative, social, scientific, and economic reforms, established royal authority in the early years of the dynasty, and is attributed with creating Hangul, the Korean alphabet.
