Kyŏngguk taejŏn

Kyŏngguk taejŏn, name translated as the State Code or the National Code, 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, it had been a basis for over 500 years of Joseon politics.
The previous code of law was the Kyŏngje yukchŏn and its revised edition, Sogyukchŏn which were issued during the reign of the state founder, King Taejo.
The code was commissioned in 1458 by King Sejo. In 1467, the compilation of the entire book was finished and named Kyŏngguk taejŏn, but repeated revisions and supplements delayed the final publication. When Seongjong was crowned, a first revision began to be implemented in 1471 and is named Sinmyo taejŏn. It was then revised in 1474 and therefore named the Gabo taejŏn. A third version, the Eulsa taejŏn, was released in 1485, and was registered as the final version.
The existing edition is a reprint from 1613 which has been preserved in the Kyujanggak Institute for [Korean Studies].
