Gyeongguk daejeon

Gyeongguk daejeon (translated as the State Code or the National Code ) is a code of law that comprises all the laws, customs and decrees released since the late Goryeo Dynasty to the early Joseon Dynasty. Sorted according to the relevant Ministries (Yukyo), it had been a basis for over 500 years of Joseon Dynasty politics.

The previous code of law was the Gyeongje yukjeon, Six Codes of Governance ) and its revised edition, Sokyukjeon (, Amended Six Codes of Governance ) which were issued during the reign of the state founder, King Taejo.

The new compilation started in 1460 (Sejo 6). In 1467 (Sejo 13), the compilation of the entire book was finished and named Gyeongguk Daejeon, 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 Daejeon. It was then revised in 1474 and therefore named the Gabo Daejeon. A third version, the Eulsa Daejeon, was released in 1485 (Seongjong 32), and was registered as the final version.
