Kyà Ângguk taejà Ân (), 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 (Yukyo), it had been a basis for over 500 years of Joseon politics.
The previous code of law was the Kyà Ângje yukchà Ân (; Six Codes of Governance) and its revised edition, Sogyukchà Ân (, Amended Six Codes of Governance) which were issued during the reign of the state founder, King Taejo.
The code was commissioned in 1458 by King Sejo. In 1467 (Sejo 13), the compilation of the entire book was finished and named Kyà Ângguk taejà Ân, 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 taejà Ân (). It was then revised in 1474 and therefore named the Kabo taejà Ân (). A third version, the à ¬lsa taejà Ân (), was released in 1485 (Seongjong 32), 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.
