Goryeosa
The Goryeosa or History of Goryeo is the principal surviving history of Korea's Goryeo Dynasty. It was composed nearly a century after the fall of Goryeo, during the reign of King Sejong. The king ordered a committee of scholars led by Kim Jongseo and Jeong Inji to compile it, based on primary and secondary sources that are no longer extant.
The Goryeo-sa, written using Hanja script, consists of 139 volumes, of which 46 consist of chronicles, 39 of geography, 2 of Chronological tables, 50 of Biographies, and 2 of lists.
