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
Although several of the basic concepts of the Korean alphabet were inherited from Indic phonology through the ’Phags-pa script, such as the relationships among the homorganic consonants and, of course, the alphabetic principle itself, Chinese phonology played a major role. Besides the grouping of letters into syllables, in functional imitation of Chinese characters, according to Ledyard it was Chinese phonology, not Indic, that determined which five consonants were basic, and were therefore to be retained from ’Phags-pa. These included the plain stop letters, ꡂ "g" for ㄱ "g" , ꡊ "d" for ㄷ "d" , and ꡎ "b" for ㅂ "b" , which were basic to Chinese theory, but which represented voiced consonants in the Indic languages and were not basic in the Indic tradition. The other two letters were the plain sibilant ꡛ "s" for ㅈ "j" (ㅈ was pronounced in the fifteenth century, as it still is in North Korea) and the liquid ꡙ "l" for ㄹ "l" .
