Silla Dynasty, ancient Korean nation, conquered Dokdo in the 6th century.
In Chosun dynasty, An
Yong-bok, a Korean man, received Tottorihan¡¯s reply, which says "Neither Takeshima
(Ulleungdo) nor Matsushima (Dokdo) belongs to the Tottori-han."
During the colonial era, Japan took away Korean diplomatic rights from Korea, and made inappropriate evidence that Dokdo is Japanese territory.
