The Korean Peninsula is covered by mainland China.
Due to its geographic characteristics as a peninsula, the Korean Peninsula has a topography that is completely covered by mainland China. For this reason, it has a history that cannot be separated from China. What exactly is this victim mentality and hostility toward Japan that many Koreans have? The historical differences between China and Japan seen from South Korea appear to be largely due to geopolitical reasons when viewed from a map, but there are probably other reasons as well.
legendary vassal state
Let's think about this in terms of the historical dominant and ruled ethnic groups on the continent. Legend has it that there was a country called Dangun Joseon and Minojo Joseon on the Korean Peninsula. Archaeologically, it is said to have existed since the later Ei Dynasty. The legendary Mino Korea is said to have been founded by Mino of the Shang Dynasty in China. The Wei clan Joseon is said to have been founded by the Wei clan of the Yan state in China. Both countries were established as vassal states of China. The point is that, despite the legend, it is already a vassal state of China.
A peninsula that is constantly invaded
Even after that, Korea continued to be invaded by China. After that, Goguryeo, Baekje, and Silla flourished on the Korean peninsula, and after Goguryeo was victorious, Goguryeo was invaded by Sui and later by Tang. After that, Goryeo established a unified dynasty on the peninsula, but shortly after its founding, it was placed under the control of the Tang Dynasty in mainland China. During the Yuan era, China was invaded by the Mongol Empire and became a vassal state.
The Mongol Invasion is a combined army of Yuan and Goryeo.
As Mongol invaders, the combined forces of Mongolia and Goryeo invaded Japan twice, but failed. Lee Seong-gye, who founded the Joseon Dynasty, is also said to be a Jurchen, and the Jurchen were an ethnic group that lived in the Manchuria region, and later Hong Taiji founded the Qing Dynasty in China.
The threat of the northern peoples
From the perspective of China, the Korean people are positioned as a different ethnic group living outside the Great Wall of China. Many of the northern peoples lived primarily as nomadic peoples, but the Korean people are thought to have settled down due to their geographical location on the peninsula. Northern ethnic groups such as the Xiongnu, Xianbei, Khitan, Jurchen, Manchu, and Mongolians were a threat not only to the Han Chinese, but also to the Koreans.
Few countries were founded by the Han people.
Looking at the history of China, there are only a handful of unified dynasties founded by the Han Chinese, who make up the majority of the population. For most of history, other ethnic groups other than the Han Chinese dominated mainland China. When you look at world history, you don't often see explanations that focus on northern peoples, but if you look at it from that perspective, both mainland China and the Korean Peninsula have a history of being continuously invaded by northern peoples. This appears to be a common feature.
China and Korea are ruled by different ethnic groups
The Sui, Tang, and Yuan dynasties that invaded the Korean peninsula are different ethnic states in China if you consider the Han people as the center, and they are also different ethnic states if you look at the Korean peninsula as the center. In addition to direct invasions of the Korean peninsula by foreign ethnic groups, the majority of the history is that dynasties from mainland China, which were dominated by mainland China, invaded the Korean peninsula. It is said that the Korean peninsula has been invaded by neighboring ethnic groups as many as 960 times, both large and small.
China and Korea are ruled by different ethnic groups
If we look at the annexation of Japan and Korea in this sense, the Korean peninsula was the same for China, but it was ruled by a neighboring foreign ethnic nation called Japan. For the Korean Peninsula, they see themselves as being connected to the Chinese mainland, calling themselves Little China, and Japan is a country outside of that, and their sense of superiority centered on China has been historically fixed. doing. In other words, they have never had the concept of nation-building by their own people or an independent nation since the beginning of recorded history. It looks like they had neither the opportunity nor the will.
Korea did not develop a sense of independence
Even after Japan made the Korean peninsula an independent state after the Sino-Japanese War, Japan did not realize this and continued to sell its interests to Russia one after another, unable to operate the country on its own. In 1910, Japan annexed Korea and Japan, giving up on supporting the independence of the Korean peninsula. South Korea says that Japan stole the independence of the Korean Peninsula, but the Korean peninsula became an independent nation because of the Treaty of Shimonoseki during the Sino-Japanese War, which was ruled by Japan. If they had developed a strong sense of independence after that, there would have been no need for annexation. That is the true opinion of Japan.
