Goryeosa  The Goryeosa, or History of Goryeo, is the main surviving history of Korea's Goryeo dynasty. It was composed nearly a century after the fall of Goryeo, during the reign of King Sejong. He 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, 46 of which consist of chronicles, 39 of geography, 2 of Chronological tables, 50 of Biographies, and 2 of lists.
