South Korea marked the anniversary of the promulgation of Hangeul more than five centuries ago on Thursday with various events highlighting the history and value of the Korean alphabet.
Considered one of the simplest and most logical language writing systems in the world, Hangeul was invented by King Sejong of the Joseon Dynasty (1392-1910) in 1443 and promulgated three years later to replace an older writing system based on the Chinese script.
