The History of Hangeul

In ancient times the people of Korea do not have the letter itself, so must use a letter of china. Because the letter of china is very difficult, Korean people can not express what he wants to be expressed through writing. King Kim Sejong (1397-1450) who ruled the Choson dynasty (1392-1897) deeply regrets it, so he thought to create a new letter to his people. In the year 1443 created 28 letter Hangeul, which consists of 17 consonants and 11 vowels.
However, current commonly used letters are 40 letters, which consist of 14 single consonants, 5 consonant combination, 10 single-vowel and 11 vowel combination.
