Summary
1. Usan was a kingdom that ruled Ulleungdo and Usando (Dokdo).
2. General Isabu annexed Usan to Silla in 512, as recorded in History of the Three Kingdoms.
3. The Annals of King Sejong Geographical Records states, “Usan and Mureungdo are close enough that the other is visible on a clear day.”
4. New and Expanded Complete Conspectus of the Territory of the Eastern Country contains detailed descriptions about Ulleungdo and Usando in the Gangwon-do, Uljin County section. Thus, Korean historical records show the two islands as being Korean territory.
Teacher Notes
Numerous historical sources indicate the Korean sovereignty over Dokdo. As seen in Dokdo Chronicle, Dokdo’s history can be traced back to the Silla era. In most historical texts, Dokdo is mentioned together with Ulleungdo. From the Goryeo period through the Joseon period, Dokdo’s sovereignty can be verified through the larger number of references in extant historical documents. Primary sources that preserve Dokdo records include History of the Three Kingdoms, History of Goryeo, The Annals of King Sejong Geographical Records, New and Expanded Complete Conspectus of the Territory of the Eastern Kingdom, Compilation of Reference Documents on the Eastern Country, Essentials of Governance, and other texts.
