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
During the 15th and 16th centuries, Joseon enjoyed many benevolent rulers who promoted education and science. Most notable among them was Sejong the Great (r. 1418–50), who personally created and promulgated Hangul, the Korean alphabet. This golden age saw great cultural and scientific advancements, including in printing, meteorological observation, astronomy, calendar science, ceramics, military technology, geography, cartography, medicine, and agricultural technology, some of which were unrivaled elsewhere.
