1046 After the demise of the Shang Dynasty, Ji Zi, an aristocrat of the Shang Dynasty, was established in the Liao River Basin by the Zhou Dynasty, and was known as Jizi Korea in history. During the Warring States Period, due to Yan's eastward expedition, North Korea was forced to flee to the Korean Peninsula. In the early years of the Western Han Dynasty, Wei Man Korea replaced Jizi Korea, which was destroyed by Emperor Wudi of the Han Dynasty in 108, and four counties of the Han Dynasty were established and merged into the territory of the Central Plains Dynasty.
However, the Han dynasty's rule over the south-central part of the Korean peninsula was not stable. In the later period of the Three Kingdoms, Koguryo, which rose in the northeast of China, expanded to the northern part of the Korean Peninsula and confronted Baekje and Silla in the south, until Koguryo was eliminated in the Tang Dynasty in 668. After Koguryo's death, the Tang Dynasty ruled the northern and western parts of the Korean peninsula, and Silla in the east took the opportunity to sit on the big island. After a short post-Three Kingdoms period, in 9 18, Wang Jian established the Koryo dynasty, known as Wang Koryo in history.
1392, Li Chenggui overthrew Korea and established Lee Korea, which was named by Zhu Yuanzhang, the Ming emperor, and the name of "Korea" was finally finalized. For more than 2,000 years, the Korean peninsula was either conquered by the Central Plains Dynasty or was a vassal of the Central Plains Dynasty. In the Ming and Qing dynasties, it was even called the first vassal state. It can be said that its status is very "prominent" and it enjoys the right to take precedence over the Central Plains dynasty.
However, the prominence of the "first slave" is not what South Korea wants, because since the end of World War II, South Korea has caught up with the east wind of industrial transfer in developed countries, become one of the four little dragons in Asia, and become the only developed country in Asia together with Japan.
Without a glorious history corresponding to it, how can we achieve such long-term development achievements? In addition, China's economic development level is not as good as South Korea's for a long time, which makes it more difficult for South Korea to accept the history of a vassal state for thousands of years. Today's South Korea, like Japan, is a veritable small country, but it is also used to adding the word "big" before the country name. This is not an echo of Japanese colonialism, but an intuitive expression of South Korea's territorial ambitions.
Although it has always been the sweet potato country of the Central Plains Dynasty, the Central Plains Dynasty has always been quite loyal to North Korea. Zhu Yuanzhang also allocated a large area east of the Yalu River to North Korea, which had no territorial claim to the Korean Peninsula in essence. However, Japan, which faces North Korea across the sea, does not think so. 1868 After the Meiji Restoration, Japan expanded rapidly to the East Asian continent, with South Korea in the south of the Korean Peninsula bearing the brunt.
