This paper examines the medieval Islamic worldview in historical and geographic writings about East Asia in the tenth century, particularly two books, Murūj al-Dhahab and Kitāb al-Tanbīh wa-al-Ishrāf, by al-Masʿūdī about Korean history. This article explores the conceptual elements in the texts about Silla to reconstruct the integration process of the foundation of the Islamic world history. The thesis’ approaches the application of the synthesis of previous written knowledge from different ancient civilizations and the contemporary field data collected by the time’s Muslim network over the world. Additionally, this research refers to the period dynamics among East Asian countries and their foreign relations with the Islamic world.
The main argument is that the Islamic world created Korean history to meet Islamic theology. Particularly, al-Masʿūdī set the origin of the Silla people from Yaphet, the son of Gomer in the Bible. Also, he designated the seventh nation consisting of the people of Silla and China. He regarded the Chinese and Silla people were derived from one of the seven primal civilizations.
