How did Korea get its name?

It's simple. It turns out that their place is "the land of three Koreas", and Koreans call themselves "descendants of three Koreas". Naturally named himself Korea:

The ancient inhabitants of the southern part of the Korean Peninsula include Mahan, Chen Han and Han Ge. The name "Three Han Dynasties" first appeared in China's history book "The Biography of the Later Han Dynasties". During the Three Kingdoms period in China, the three Han nationalities were still in the stage of tribal alliance. At that time, there were more than 65438+ households in Mahan, which were divided into 54 tribes and dominated the three Han nationalities. Ma has six tribal groups, which are divided into 12. Han Ge, located in the south of Chen Han, is a place where Chen Han people live in compact communities, also known as Chen Ge. The population of Chen Han and Han Ge is * * * 45,000, and they are divided into 12 tribes respectively. The leader of the Sanhan tribe was originally Mahan. Sanhan is engaged in rice planting, sericulture and weaving. Each of the three Koreas has its own leader, the greatest of which calls himself Chen Hezhi, followed by Yi Jie, Xian Duan, the corps commander, Gui He Fan? Wait a minute. After the end of the 2nd century BC, due to the decline of the latter two counties, Mahanai people developed northward. Around A.D., Kudarabe unified the ministries, and at the beginning of the 4th century, it seized the land of Fang Jun and formed the Baekje State. Chen and North Korea were unified into Silla by the Ministry. After the 5th century, the territory of the Six-country Gaya Alliance developed by Han Ge gradually narrowed and merged into Baekje and Silla respectively. In 660, the land of the Three Kingdoms was unified by Silla.

Now Koreans (including Koreans and Koreans) call themselves "descendants of three Koreans" or "descendants of three Koreans" (referred to as "Koreans" for short), which is precisely because of this. This is similar to the truth that China people call themselves "descendants of the Chinese people".
