There was no "Three Kingdoms Unification".

 1. The manipulated "collective memory" Silla joined forces with Tang Dynasty forces to destroy Baekje in 660 and to destroy Pyongyang Castle in 668 and to end Goguryeo's resignation, establishing "Iltong Samhan" and "Samhan Integration." We often refer to this event as "three kingdoms unification," but this is the result of the contemporary concept of a nation or state built by modern and contemporary Korean history dating back 1400 and reflecting considerable problems. Incorrect terms inevitably call 'manipulation of collective memory'. History is a "collective and persistent memory shared between you and me," which leads to the "fabrication of collective memories" that Silla, Goguryeo, and Baekje were the same nation-state. Although Baekje and Goguryeo cannot be called national countries such as Silla, historical academia laid the same foundation for the map of the ancient Korean Peninsula and Manchuria established by the three kingdoms as the Korean people. These three countries clashed with each other, sometimes exchanged, and connected, and maintained vitality by nourishing 700 years of other social systems, although their relationship was closer than any other dynasty country. Given that the language is in common, the skin color is the same, or similar, the intimacy each of these three dynasties and their citizens feels toward each other may have certainly been more than that of other dynasties and their citizens. However, for that reason alone, the three kings, who have been playing separately for 700 years, cannot be called the same "ethnic." 2. We do not have the right to hold responsibility for the ancient times for why modern and contemporary forced Silla did not occupy all of Goguryeo's old land. We have no right to question why Silla brought in troops from the "two peoples" Tang Dynasty and destroyed Baekje and Goguryeo, the same "national states." Since Silla incorporated not all of Goguryeo's old land, but only part of the south of Pyongyang into its territory, it is as forced as King Gwanggaeto of Goguryeo argues that the so-called unification of the three kingdoms is "incomplete." It was Danjae Shin Chae-ho, who most fiercely advocated this insistence, who represents nationalist history. It cannot be denied that the colonial situation in Joseon at the time demanded such a monolithic history, and that it played a great role in the integration of the Korean people and promoting the spirit of independence. However, Danjae pointed out the wrong leg. This is because in the late 19th and early 20th centuries, he projected the virtual image or imaginary community of Joseon's "national" or Joseon's "national" into Silla, Goguryeo, and Baekje. In comparison, it was like taking the degree of long and short to the wrong standard. 3. "We live together, and we die when we disperse." After liberation, Danjae Private School has established itself as an unprecedented answer in North Korea. South Korea is also another variant of neo-nationalist history and intrinsic development theory that revived in the 70s under the so-called new nationalist history led by Son Jin-tae and Lee In-young, who dominated the Department of National History at Seoul National University. Look at what Son Jin-tae left right after liberation. Whatever it is, the signs of fascism emitted by the nation and the state block their noses and cover their eyes and close their mouths. Son Jin-tae says in Guksadae. "We live when we get together, and we die when we get apart." The fascist slogan of politician Rhee Syng-man is being transformed from history Son Jin-tae. Strictly speaking, there are no people in Son Jin-tae's history. There is only a symphony of the people, the state, and the people. Values such as the right to freedom suffocated by the slogan of totalism of "living together" under the banner of national revival and national development. Silla's so-called reunification of the Later Three Kingdoms, which succeeded Goguryeo because it attracted "two-ethnic troops" and destroyed its own people and achieved incomplete territorial unification, is establishing itself as a true unified country in Korean history. Trans-history is a continuous act and process that projects such a present even in the past that does not go beyond the times and space. This trans-history of the nation and state envisioned by 20th-century history called for manipulation of both collective memories, even though it was not anywhere on the Korean Peninsula and Manchuria established 1,500 years ago by the Three Kingdoms. Therefore, hyperhistory and collective memory manipulation are synonyms. The so-called unification of the Three Kingdoms by Silla was a hubby that did not exist and could not be done.
