Kyŏngguk taejŏn (Korean: 경국대전; Hanja: 經國大典), name translated as the State Code[1] or the National Code,[2] is a code of law that comprises all the laws, customs and decrees of the late Goryeo to early Joseon periods in Korea.
Sorted according to the relevant ministries (Yukyo), it had been a basis for over 500 years of Joseon politics.
In 1467 (Sejo 13), the compilation of the entire book was finished and named Kyŏngguk taejŏn, but repeated revisions and supplements have delayed the final publication.
When Seongjong was crowned, a first revision began to be implemented in 1471 and is named Sinmyo taejŏn (신묘대전; 辛卯大典).
It was then revised in 1474 and therefore named the Gabo taejŏn (갑오대전; 甲午大典).
