Se-Jong is the 23rd pattern taught to ITF Taekwondo students (after So-San). It is one of the 5th-degree black belt forms used in ITF Taekwondo.
This form is named after Se Jong the Great, the Korean king who is credited with the development of the the Korean Hangul alphabet in 1443 C.E. The diagram for this form represents the king, while the 24 movements refer to the 24 letters of the Korean alphabet.
