The Bronze Age on the Korean Peninsula was around the 15th century B.C.

 The Bronze Age on the Korean Peninsula eventually collapsed as the Korean archaeological conventional wisdom of around the 10th century BC rose to around the 15th century BC, much earlier than this in various parts of the country. As a result, not only the ancient history of Korean history, which does not have a documentary record of the time, but also the ancient history, which begins with the History of the Three Kingdoms, has a new turning point. In addition, these results are evaluated as a major event in Korean history compared to the excavation of Pungnaptoseong Fortress or the discovery of manuscripts of the Hwarang Century. Until now, the Korean archaeological community has considered that the southern central and southern parts of the Korean Peninsula entered the Bronze Age of using patterned earthenware at the earliest around the 10th century of B.C., and the current national history textbooks are the same. However, the results of various chronological measurements of Bronze Age ruins and relics recently identified in the submerged area of the Namgang Dam in Jinju, Gangwon-do, and Jeollanam-do adjacent to North Korea are appearing around the 15th century of B.C. beyond this conventional wisdom. What is even more surprising is that the highly developed Bronze Age itself, including dolmens and non-wave-shaped bronze swords, which are representative tombs of the Bronze Age, has been confirmed to be in or before the 10th century of B.C. These results prove that the claim that the opening of the Bronze Age on the Korean Peninsula was right before the excavation of Dangunneung Tomb in 1993 was around the 20th century of B.C. and that the South Korean academic community, which had rejected it, was completely defeated. The recently investigated submerged area of the Jinju Namgang River is coming out around the 15th century of the B.C., with various Bronze Age ruins and relics identified here well beyond the 10th century of the B.C. In the case of the remains of Okbang excavated by the Seonmun University investigation team among the submerged areas of the Namgang River, the National Research Institute of Cultural Heritage's radioactive carbon dating results showed that it was B.C.1590-1310 and B.C.1620-1400, respectively. These results were similar in other Namgang submerged areas, with two charcoal excavated from Bronze Age residences excavated by Konkuk University Museum also found to have surpassed the 10th century B.C. 1420-B.C. 1100 and B.C. 1400-B.C. 1100 BC. In the case of Gangwon-do, the Bronze Age is rising further than the Namgang River basin. In the case of Gangneung Gyo-dong Residential Area 1, the date was found to be 1878-1521, and the other two residential maps were found to be around the 15th century of B.C. In addition, the only Bronze Age ruins in Joyang-dong, Sokcho, where bronze axes were excavated in South Korea, were also found to be B.C. 1206 - B.C. 830, and the remains of Bangnae-ri, Gangneung, which was measured by Nagoya University in Japan, were also B.C. 14th century at the earliest. In addition, as a result of requesting a foreign laboratory to measure carbon dating on a Bronze Age residential map in Juknae-ri, Suncheon, Jeollanam-do, which was discovered by the Chosun University Museum, the results were B.C. 15th to 16th centuries. What is noteworthy here is that these solidarity measures did not come from one specific research institute, but were obtained by commissioning various domestic and foreign institutions. This is increasing the reliability of these chronological measures. In addition to the ruins of the house site, the occurrence of dolmens and bronze is also rising. The dolmen ruins in Birae-dong, Daejeon, where the bifa-shaped bronze bronze dagger was excavated, and the ruins in Joyang-dong, Sokcho, where bronze axes were found, were dating from the 9th to 10th centuries BC. Given that these non-wave-shaped bronze axes are relics of great casting technology among bronze, it became clear that the crude level of bronze ware, which preceded them in the Korean Peninsula, appeared earlier than this. Cho Yoo-jeon, director of the National Research Institute of Cultural Heritage, said, "Until the prehistoric remains of the Namgang River came out, we estimated that it was around 400-500 B.C.," adding, "Archeology breaks down theories after sleeping, and the Bronze Age is also entering a new stage."
