Do Goryeo and Goguryeo refer to the same country?

Now that Goguryeo and Goryeo are mentioned, many people will ignore the difference between them because the two names are similar. Some people even think that Goguryeo and Goryeo are the same place. In fact, Goguryeo and Goryeo are not the same at all. They are not the same nation. They are only similar in name because of their close names. ?

First of all, Goguryeo originated in the northeast of my country. Probably during the Yuan Dynasty of the Western Han Dynasty, Prince Zhu Meng of Fuyu failed in the domestic political struggle and went to Goguryeo County, Tujun to establish a country. This is how the country got its name. . Then Goguryeo gradually expanded and developed, and once became the largest force in the Liaodong region, and even the northern part of the Korean Peninsula was under its control. This is why Koreans say that Goguryeo belongs to them.

More than two hundred years after the demise of Goguryeo, the country of Goguryeo appeared on the Korean Peninsula. The founder of Goguryeo was Wang Jian. Although it was named "Later Goguryeo", it actually had nothing to do with Goguryeo. It was founded by the three Han people of Silla. At that time, Silla, a powerful country on the Korean peninsula, had gradually declined. Gongyi, the concubine of King Silla, established the post-Goguryeo Kingdom, which was in opposition to Silla and Baekje (later).

After the founding of the country, Goguryeo has been trying to provoke the Central Plains, and it was very disrespectful to the Central Plains emperors at that time. Goguryeo was once powerful, and Emperor Yang of the Sui Dynasty sent troops to conquer it many times. During the war, millions of people died. It directly shook the ruling class of the Sui Dynasty, and was later eliminated by Li Zhi. As mentioned above, the Tang Dynasty also set up counties in Goguryeo, but in the later period, in order to facilitate management, the residents here were immigrated. In places such as Jianghuai and Henan, there are also some Goguryeo who were not immigrated to these places. They later joined the Turkic tribes or entered Silla and other places. However, the number of these Goguryeo people was not large, so it can be considered that the Goguryeo people have already Integrated into the Central Plains system, they do not belong to any nation. The genes of the Goguryeo people are more complicated, including genes from the Han people in the Central Plains and Japanese genes, so it seems that Goguryeo and Goryeo are not the same nation.
