Have you heard about “King Sejong the Great” and “Hangeul”?

King Sejong the Great (May 7, 1397 – May 18, 1450, who was the fourth king of the Joseon Dynasty of Korea) profoundly impacted Korean history with his introduction of hangeul, the native phonetic alphabet system for the Korean language.

Before the creation of Hangul, only members of the highest class were literate (hanja was typically used to write Korean by using adapted Chinese characters, while Hanmun was sometimes used to write court documents in classical Chinese). One would have to learn the quite complex hanja characters in order to read and write Korean. Further, despite modifications to the Chinese characters, hanja could prove cumbersome when transcribing the Korean language, due to considerable differences in grammar and sentence order.
King Sejong presided over the introduction of the 28-letter Korean alphabet, with the explicit goal being that Koreans from all classes would read and write. He also attempted to establish a cultural identity for his people through its unique script. While creating the alphabet, King Sejong encountered opposition of courtiers. First published in 1446, anyone could learn Hangul in a matter of days. Persons previously unfamiliar with Hangul can typically pronounce Korean script accurately after only a few hours study.

Each hangul letter is based on a simplified diagram of the patterns made by the mouth, tongue and teeth when making the sound related to the character. Morphemes are built by writing the characters in syllabic blocks. The blocks of letters are then strung together linearly.

There was a drama called “뿌리 깊은 나무” which was about King Sejong and the origin of Hangeul. This drama won “The best Korean drama award”. I would like to recommend it if you are a huge Korean drama fan.
