I wrote an article about Yamatai country before, but this time I will investigate a little more deeply why Himiko made a tribute.
The reason is "to gain an advantage over the southern part of the Korean Peninsula to get iron", but apparently "the reason for tribute to the Korean Peninsula at that time" can be seen from the situation in China and the Korean Peninsula.
This time, " Relationship between Himiko and Wei I will write.
Mainland China during the Himiko era
It was the era of Himiko, that is, before 248 years.
In 239 (described as 238 in Wajinden), Himiko dispatched a lord named Nashime and his deputy ambassador, Ushiri, to Daifang-gun.
On the map of 237, Daifang-gun is in the position of "swallow" on this map. Lelang County in the north and Daifang County in the south.
Daifang-gun is under the direct control of Wei, located in the midwestern part of the Korean Peninsula, south of Lelang-gun, between 204 and 313. There is also a theory that it was like a colony.
This land called Daifang-gun is one of the areas controlled by the family after the independence of Gongsun Du, who was the taishou of Liaodong-gun during the Eastern Han era. Cao Cao laid the foundation for Wei It is believed that Gongsun Kang actually belonged to the country of Wei after Gongsun Kang was appointed to the person.
By the way, when you think of Cao Cao, you think of Sangokushi. However, Cao Cao did not live in the Three Kingdoms era.
It was a turbulent world that began with the peasant revolt and the Yellow Turban Rebellion in 184, but it was initially an era of group male division. After Cao Cao, who had the Han emperor in his hand from early on, took control of Zhongyuan (North China Plain in the Yellow River basin), Wei would be in a superior position after that.
Kure, which was established in the Yangtze River basin, and Shu, which was built in Yizhou, gradually gained strength in the form of almost simultaneous progress.
In the Romance of the Three Kingdoms, which we often hear, it is easy to make a mistake because Cao Cao of Wei, Son of Wu, and Liu Bei of Shu are the center of the story, but it was about 36 years after the Yellow Turban Rebellion that we actually entered the Three Kingdoms era. .. Cao Cao dies and his son Cao Pi Has succeeded, and it started after the emperor of the Han dynasty, the emperor Xian, handed over the throne.
In the midst of the Three Kingdoms era, Himiko sent a messenger in 239, but around 239, a little trouble occurred on the Korean Peninsula.
First, in 238, when Gongsun Yuan of Taishou, Liaodong-gun formed an alliance with Wu and planned independence, Sima Yi was dispatched from Wei and Gongsun Yuan was executed.
Himiko had been sending messengers until then, but there is a theory that he was blocked by Mr. Yan, but even so, this timing. It's natural to think that you knew most of the information. Information may have been collected based on the village of Wajin, who is said to have been in the southern part of the Korean Peninsula.
Then, three years later, in 242, a country adjacent to Daifang-gun called Goguryeo invaded Wei, and the conflict became apparent.
As you can see from the positional relationship between Goguryeo, Kure, and Daifang-gun, the Japanese archipelago, these three countries are in a very easy position to attack from Wakoku.
For this reason, Wei seems to have sent a gold seal to Wakoku with exceptional treatment (mainly a copper seal other than the gold seal of "King of Na Gold Seal"). (Photo from wikipedia)
