Many years ago, kimchi was merely regarded as a salted vegetable. Yet, throughout the 12th century, with the addition of several spices and seasonings, it grew steadily in popularity. It wasn't until the 18th century that hot red pepper was finally used as one of the major ingredients for making kimchi. In fact, the very same kimchi as we know it today has retained the same qualities and cooking preparations that prevailed ever since it was first introduced.
