According to "Geographies" in the Samguk sagi, Daegaya existed for about 520 years from the first king, Ijinasi (이진아시왕), to the last, Doseolji (도설지왕). Daegaya had sixteen kings from King Ijinasi to King Doseolji, but only five of those are known. The first king was Ijinasi, the ninth king Inoe, the sixteenth king Doseolji, and King Haji, whose generation is uncertain. King Haji (하지, 荷知) sent an embassy to Namje (南齊, in Southern Qi) in 479. According to Chinese records, he received a rank of the third order, one rank below Baekje and Silla.
Daegaya developed quickly and played a major role in the Gaya confederacy in the 5th century AD, partly because of its advanced steel-making craft, but its progress and that of the confederacy were limited by the neighboring kingdoms of Baekje and Silla, which were more fully developed as centralized political entities. Incidental historical records and archaeological findings indicate a highly stratified aristocratic society in Daegaya and the Gaya confederacy at this time.
King Haji allied with Baekje and Silla to attack Goguryeo in 481. Daegaya allied with Baekje to attack Silla (which, for Baekje, was in response to Silla's breach of their 120-year truce) at the battle of Gwansan Fortress in 554, but both Baekje and Gaya suffered heavy losses. This confrontation policy alienated the other member states of the Gaya confederation, and Daegaya lost its leadership of Gaya to Ara Gaya.
Daegaya fell to the armies of Silla under general Kim Isabu in 562; Silla, having already begun to absorb much of the Gaya confederacy, had invaded Daegaya as punishment for having allied with Baekje in 554.
Archaeologically confirmed remains include Ancient Tombs in Jisan-dong. its turned out to be the tombs of the ruling class of Daegaya.
Etymology of the name
The name Daegaya is suspected to be first used around the late Gaya Confederacy. The name itself were also used by Geumgwan Gaya during the early days of Gaya Confederacy.
Baekje or Paekche was a Korean kingdom located in southwestern Korea from 18 BC to 660 AD. It was one of the Three Kingdoms of Korea, together with Goguryeo and Silla. While the three kingdoms were in separate existence, Baekje had the highest population of approximately 3,800,000 people, which was much larger than that of Silla and similar to that of Goguryeo.
The Three Kingdoms of Korea or Samhan competed for hegemony over the Korean Peninsula during the ancient period of Korean history. During the Three Kingdoms period (Korean: 삼국시대), many states and statelets consolidated until, after Buyeo was annexed in 494 and Gaya was annexed in 562, only three remained on the Korean Peninsula: Goguryeo, Baekje and Silla. The "Korean Three Kingdoms" contributed to what would become Korea; and the Goguryeo, Baekje and Silla peoples became the Korean people.
Silla, was a Korean kingdom that existed between 57 BCE – 935 CE and was located on the southern and central parts of the Korean Peninsula. Silla, along with Baekje and Goguryeo, formed the Three Kingdoms of Korea. Silla had the lowest population of the three, approximately 850,000 people, significantly smaller than those of Baekje and Goguryeo.
Sabi (Korean: 사비) was the third and final capital of the Korean kingdom of Baekje, from 538 until Baekje’s fall in 660 CE. The site of Sabi is located in modern-day Buyeo County, South Chungcheong Province, in South Korea.
Kim is the most common surname in Korea. As of the 2015 South Korean census, there were 10,689,959 people by this name in South Korea or 21.5% of the population. Although the surname is always pronounced the same, dozens of different family clans use it. The clan system in Korea is unique from the surname systems of other countries. Kim is written as 김 in both North and South Korea. The hanja for Kim, 金, can also be transliterated as 금 which means 'gold, metal, iron'. While romanized as Kim by 99.3% of the population, other rare variant romanizations such as Gim, Ghim, and Kin make up the remaining 0.7%.
Kim Yu-sin was a Korean military general and politician in 7th-century Silla. He led the unification of the Korean Peninsula by Silla under the reign of King Muyeol and King Munmu. He is said to have been the great-grandchild of King Guhae of Geumgwan Gaya, the last ruler of the Geumgwan Gaya state. This would have given him a very high position in the Silla bone rank system, which governed the political and military status that a person could attain.
Seong of Baekje was the 26th king of Baekje, one of the Three Kingdoms of Korea. He was a son of Muryeong of Baekje and is best known for making Buddhism the state religion, moving the national capital to Sabi, and reclaiming the center of the Korean Peninsula. His demise eventually came at the hands of an ally who betrayed him. The name Seong translates as 'The Holy.'
Gaya was a Korean confederacy of territorial polities in the Nakdong River basin of southern Korea, growing out of the Byeonhan confederacy of the Samhan period.
Geumgwan Gaya (43–532), also known as Bon-Gaya or Garakguk, was the ruling city-state of the Gaya confederacy during the Three Kingdoms period in Korea. It is believed to have been located around the modern-day city of Gimhae, Southern Gyeongsang province, near the mouth of the Nakdong River. Due to its geographic location, this kingdom played a dominant role in the regional affairs from the Byeonhan period onward to the end of the Gaya confederacy.
Ara Gaya, also known as Ana Gaya, Asiryangguk, and Anra, Alla, was a city-state kingdom in the part of Gaya confederacy, in modern-day Haman County of South Korea in the 6th century.
Goryeong Gaya was one of the lesser chiefdoms of the Gaya confederacy during the Three Kingdoms of Korea. It was centered in present-day Sangju, North Gyeongsang Province, South Korea. Legend indicates that it was founded by a King Taejo, to whom a tomb on Obong Mountain in Hamchang-eup, Sangju, is attributed.
Samhan, or Three Han, is the collective name of the Byeonhan, Jinhan, and Mahan confederacies that emerged in the first century BC during the Proto–Three Kingdoms of Korea, or Samhan, period. Located in the central and southern regions of the Korean Peninsula, the Samhan confederacies eventually merged and developed into the Baekje, Gaya, and Silla kingdoms. The name "Samhan" also refers to the Three Kingdoms of Korea.
Korea's military history spans thousands of years, beginning with the ancient nation of Gojoseon and continuing into the present day with the countries of North Korea and South Korea, and is notable for its many successful triumphs over invaders.
Jinheung of Silla was the 24th monarch of Silla, one of the Three Kingdoms of Korea.
Kim Mu-ryeok was a Silla general under King Jinheung in the mid-6th century. The events of his life are known solely through a brief account in the 12th-century chronicle Samguk Sagi. He was the second son of King Guhae, the last ruler of Geumgwan Gaya, who had joined his family with the true-bone elites of Silla. After his father's surrender in 532, Kim joined the Silla military at the high rank of gakgan. In 553, he led his army to seize the northeastern frontier of Baekje. After taking the area, Kim was made the military governor of Sinju. In 554, he met the Baekje armies at Gwansanseong Fortress, killing King Seong and four of his ministers, and taking some 29,000 prisoners.
Guhyeong of Geumgwan Gaya, also often Guhae was the tenth and final ruler of Geumgwan Gaya, a Gaya state of ancient Korea. He was the son of King Gyeomji and Queen Suk.
The Gaya Confederacy originated, as legend tells it, from a collection of folktales and accounts from Korean history. The legend explains that Gaya came from heaven by way of six eggs and hatched human men who would become Kings to the Gaya Kingdoms. All six Kings became rulers of the six different Gayas called Geumgwan Gaya, Daegaya, Seongsan Gaya, Ara Gaya, Goryeong Gaya, and Sogaya. Each of the Gaya states had their own unique culture and life. However, Geumgwna Gaya was the center of them all. Geumgwan Gaya consisted of nine villages and was integrated by King Suro of Gaya.
Yamato Japan and the Gaya Confederacy, which were located directly across the Korea Strait from one another, had very close diplomatic and commercial ties since prehistory until the conquest of Gaya by Silla in 562 AD.
Ijinasi or Naejinjuji (內珍朱智) was the founder and first king of Daegaya.
