When was Hangul invented?
Origin of Hangul
The Korean alphabet is the native script of Korea, created in the mid fifteenth century by King Sejong,[1][2] as both a complement and an alternative to the logographic Sino-Korean hanja. Initially denounced by the educated class as eonmun (vernacular writing), it only became the primary Korean script following independence from Japan in the mid-20th century.[3]
Hangul
Indo-Arabic numerals are mixed in with the Korean alphabet, e.g. (22 March 2007).
