Located 87.4km away from Ulleungdo Island, and formed entirely from volcanic rock, Dokdo is an isolated island off the east coast of Korea bearing a latitude of 37°14' north and a longitude of 131°52' east. Collectively, both Ulleungdo Island and Dokdo once belonged to a country named Usanguk. According to geographical records, Usanguk became part of the Silla Kingdom (57B.C. ~ 935 A.D.) in June of the 13th year that King Jijeung ruled Silla. Isabu (a general and politician of Silla) gained significant strength during this period to overtake Usanguk.In the Seongjong Memoir of the Joseon Dynasty, there are passages by Kim Jaju describing Dokdo, which was referred to as Sambongdo at the time. Dokdo was initially called 'Sambongdo', 'Gajido' or 'Usando', but the name was later changed to Dokdo in 1881. The name 'Dokdo' was first used in 1906 by the Headman of Ulleung County Sim Heungtaek. In 1914, Dokdo officially became an administrative district of the Gyeongsangbuk-do.After The Japanese Invasion of Korea in 1592, Japanese fishermen often came near Ulleungdo and Dokdo. Sukjong Sillok, the Annals of King Suk Jong (1674-1720), records that An Yong-bok went to Japan twice in order to protest against Japanese nationals trespassing into Korean territory. He asked the Japanese authorities to recognize Korea's sovereignty over these islands and to forbid Japanese nationals to sail to Dokdo.Dokdo is comprised of two main islands: Dongdo, or East Island which sits 98m above sea level, and Seodo, or West Island, which sits 168m above sea level, together with 36 smaller rock formations. Seperating Dongdo and Seodo is the Hyeongjegul Cave, together with Cheonsanggul Cave on Dongdo. Over time, other caves and topographic features of the island formed due to weathering and erosion.Japan acknowledged the value of Dokdo after the Russo-Japanese War of 1905. Japan unilaterally transferred Dokdo to Shimane Prefecture, Japan and renamed it "Dakesima". Several authorities in Japan have continuously declared their dominion, over the island, which led to diplomatic conflicts between Korea and Japan. Such conflicts have yet to be resolved.Presently there are security guards on Dokdo that protect several houses that were built onto the rocks as well as a small harbor.
