Hangul refers to the name of the Korean alphabet, and is being recognized as the most valuable cultural asset of Korean People and the most scientific alphabet in the world. Sejong, the 4th King of Joseon Dynasty created Hangul in 1443 and distributed it with the name of Hunminjeongeum in 1446.

It originally had 28 letters but four letters of "ㆍㆆㅿㆁ" are currently not used and only 24 letters are being used. First, Hangul is easy to learn. The epilogue of Jeong In-ji included in the Hunminjeongeum Manual says "Smart one will learn it before the morning and even stupid one can learn it in ten days".

Second, Hangul is a scientific alphabet imitated speech organs. Consonants imitated the shape of speech organs and vowels imitated sky (·), land (ㅡ) and human (ㅣ), and letters are made as systematic derivatives of these.
(ex : ㄱ ㅋ ㄲ, ㄷ ㅌ ㄸ, ㅏ ㅑ, ㅓ ㅕ, ㅗ ㅛ)

Third, Hangul is made in a unique way. Most of alphabets in the world became the ones of these days through going through complicated changes for a long time, or imitated or borrowed letters of other alphabets such as Japanese alphabet or English alphabet. However, Hangul was made by King Sejong in a unique way.

Fourth, the objective to create it, its creator and created time are clear. There are more than 3000 languages in the world these days, and only around 100 languages among them have their own alphabets and even these don't have the clear objective to be created, their creators and created time.

Fifth, Hangul serves as phonemes and syllables at the same time.

Sixth, Hangul can express various things. The Hunminjeongeum Manual says "Every sound including those of wind, birds, cocks, dogs and even foreign languages".
The total number of possible pronunciations which Hangul has reaches 12,768, making it as the alphabet with the most pronunciations in the world. UNESCO designated Hunminjeongeum as World Heritage at the 3rd International Advisory Meeting held from September 29 to October 1 in 1997, and has awarded King Sejong Prize on October 9th of every year to the one who most contributed to global literacy since 1990 in order to pay a tribute to King Sejong's efforts to stamp out illiteracy.?It was named as 'Hangul' in 1913 by Joo Si-kyeong in 1913.
