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.
Sungkyunkwan
The primary written language of Sungkyunkwan was hanja. Although hangul was invented in 1443, it did not become the primary language of study because the literary elite believed that the difficult hanja was more sophisticated. Hangul was invented to solve the widespread illiteracy of the common people at the time, but it was considered a threat by many in the upper class to their status as literary scholars, leading them to resist its implementation. As a result, hanja remained the written language used at Sungkyunkwan requiring anyone who wished to rise to the top levels of the government to be capable of reading and writing the characters.
