Before I talk about the biography of each Sengoku daimyo, I have to understand what the situation was like at that time, so this time I will investigate the country of Kai just before the Sengoku period.
Outbreak of Uesugi Zenshu's Ran
It was 1416 that the country of Kai was confused during the Muromachi period. Uesugi Zenshu's Ran is.
The predecessor Kanto Kanrei, Zenshu Uesugi, rebelled against Mr. Ashikaga Mochiuji of Kamakura.
Kamakura Koga was the secretary of Kamakura-fu, an organization that governs the 10 countries in the Kanto region at that time, and Kai Province was also included in the countries governed by Kamakura-fu. Therefore, the protection of Kai Province cannot be irrelevant.
The 13th head of the family, Nobumitsu Takeda , is the guardian of Kai Province. Was also a relative of Zenshu, so I will participate in the war as Zenshu. At that time, the relationship between Kamakura-fu and the Muromachi Shogunate was already bad, but Zenshu's relatives were Shogun Ashikaga Yoshimochi . I have a younger brother, " Ashikaga Yoshimochi ], My younger brother was carried.
Due to such circumstances, Uesugi Zenshu's Ran The Shogunate will also participate in. Of course, Kamakura-fu and the Shogunate could not be won by the former Kanto Kanrei alone, and the country of Kai would be in a state of absence of protection.
What have you been waiting for after the rebellion ...?
Among the forces in Kai, Yunao Henmi, a national based in the northwest, was involved in the turmoil of Zenshu Uesugi as Mr. Mochiuji of Kamakura Koga, so Mr. Mochiuji was seen as a guardian of Kai no Kuni. I recommend him.
The shogunate attached to Mr. Mochiuji of Kantō Kubō due to internal circumstances, and did not support Mr. Mochiuji himself. Rather, the shogunate was adopted by Mr. Anayama, who had been retired, and relegated and renamed Nobumitsu's younger brother, Manharu, and assigned him as a guardian as Nobumitsu Takeda.
Due to the Uesugi Zenshu turbulence, the Anayama family, who have Nobumoto's adoptive parents, and the Izumi family, who are recommended by Kamakura-fu, have gained power. Because he was a direct vassal of the Shogunate, " Kokujin in Kai had considerable influence ], Mr. Takeda's influence is relatively low.
If there is no guardian power, Shugodai (Mr. Atobe) will also aim for that authority.
Anyway, it seems that he was very confused (in addition to Anayama and Izumi, there are also forces such as Kurihara in the east, Kato, Oi, and Oyamada in the west. There are too many, so the figure below is omitted).
Mr. Ogasawara, who was the guardian of Shinano, is located between the Shogunate and Kamakura-fu, so he is often removed from the guardianship depending on the situation. It is said that he was relatively loyal to the Muromachi Shogunate and was supporting Nobumoto because of the Shogunate's life (By the way, Mr. Atobe's rise in Kai was dispatched by Mr. Ogasawara as a guardian. Begins).
Changes in the internal circumstances of Kai Province
It was 1465 that the inside of Kai Province changed a little. That. 16th head of the family, Nobumasa Takeda Succeeds in excluding Mr. Atobe of Shugodai.
I thought it would finally settle down a little 1467 From then on, the Onin War began, and the Ogasawara clan in Shinano, a neighboring country, also broke out in a family dispute. In addition, famine, plague, and riots occurred in quick succession. Influential people not only in Kai but also abroad will start to show their independence, and like other countries, Kai will enter into a state of turmoil.
Meanwhile, 1491 Nobutsuna, the firstborn of Nobutsuna, inherited the Takeda family's reign.
However, although Nobumasa should have handed over the family reign, he began to desire the inheritance of his second son, Aburakawa Nobuyoshi, and the Takeda family had to deal not only with the war in Kai but also with the internal conflict. lost. As in other regions, you will be in a mess when you try to outsmart your opponent by connecting with an outside influential person in an internal conflict.
As the battle continues in Kai, the pinch continues. Invaded by Mr. Imagawa from Suruga to Kai Province, Isemoriki (Hojo Soun) from Sagami Invaded by, the conflict at the border has continued frequently since then.
Once 1495 and 1498 Due to the large earthquake "Meio Earthquake" that occurred in the Nankai Trough, Takeda Nobutsuna and Nobutsuna / Nobue reconciled, but Nobutsuna's death was split again.
After all, it is Nobutora Takeda that Kai Province is united. I will wait until the success of.
Shingen Takeda I would like to write in another biography.
