However, Kamakura Shogunate / Edo Shogunate In the Kanto region administration like this, the influence reached the Tohoku region.
Prosperity of Mr. Fujiwara Oshu
From around the end of the Heian period, Oshu Fujiwara centered on the Kitakami River basin Hiraizumi, which has been registered as a World Heritage Site, will develop into the second largest city in Japan after Heiankyo. It is said that the goods were saved by collecting taxes on the territories of both Mutsu and Dewa and the customs villas.
However, Minamoto no Yoshitsune Minamoto no Yoritomo opened the Kamakura Shogunate for concealing Will be attacked and destroyed. After that, the samurai, mainly from the current Ibaraki prefecture, came to rule, and the territory of the Hojo clan was set.
From the Hojo Tokusou family, Mr. Ando Is Ezo Kanrei Dispatched as Tosaminato to control Hokkaido from the north Tohoku region ( Tosa Minato ), It has become one of Japan's leading cities with active trade. However, in the Muromachi period, due to a conflict with the Nanbu clan, he was chased from the Tsugaru region and moved to the Akita region, and its prosperity was lost.

Date Tanemune's breakthrough
During the time of the 11th head of the family, Date Mochimune, despite being located in the Tohoku region, away from Kyoto, he made donations to the Muromachi Shogunate and made many tributes to Tokyo. These efforts have paid off, and successive heads of the family have come to receive the name of the shogun. 14th head of the family, Tanemune Is 1517 Shogun Ashikaga Yoshitane I got a letter from.
While building a close relationship with the Shogunate, Tanemune Expansion of power through political marriage I was trying. He has adopted and adopted more than 10 of the 21 girls in the influential families of Oshu. However, these policies have complicated marital and stakeholder relationships and have also triggered conflicts.
1520 Tanemune married to Tanemune's younger sister Died, and Tanemune intervened in the battle for the family reign, but the Mogami generals rebelled and Date and Mogami confronted each other.
1522 Originally there was no guardianship in Mutsu, but from the Shogunate [ Mutsu Guardian ] Will be appointed. With this appointment of the Mutsu Province Guardian, the Osaki and Mogami clan's Oshu and Ushu tandai system virtually collapsed, and Date gained the cause of governing the Tohoku region.
In this way, Mogami, Soma, Ashina, Osaki, Kasai Date Tanemune who was able to subordinate the daimyo of Minami Ou and take control of the Tohoku region. 1533 to control the whole house To [ Kurakata no Rule ] Was established, and [ Building Diary ] And 1538 [ Money book ], Etc. Create a tax ledger.
In addition, we have enacted the Bunkokuho [Dust Collection], which covers Article 171.
Date Tanemune and Harumune vie for astronomical turmoil
Date Tanemune Due to the concentration of power and the conflict of opinions, the conflict with his firstborn, Date Harumune, intensifies.
Considering further territorial expansion, Tanemune proposed to send his third son, Date Sanemoto, to Mr. Uesugi for adoption, and the conflict between the father and son became decisive. 1542 Harumune attacked Tanemune aiming at the return route of falconry and was imprisoned in Nishiyama Castle.
However, Munecho Koyagawa Tanemune was rescued by Tanemune and prepared for a thorough fight with Harumune.
This internal conflict between the Date clan and his parents became a tumultuous event involving the Ou Daimyo. In the early stages, many daimyo joined Tanemune, and his father took the lead. In Mutsu, Mr. Osaki and Mr. Kurokawa of the Nara sect suppressed Mr. Rusu of the Haru sect, and in Dewa, Mr. Mogami and others almost controlled.
However, 1547 Then, there was a discord between Mr. Tamura and Mr. Ashina of the sect. When he started fighting, Ashina turned over to Harumunekata. As a result, the war situation began to tilt toward Harumune, and a series of defectors from the Harumune sect.
September 1548 Yoshiteru Ashikaga Following the arbitration of Tanemune, the reign of Tanemune retired and the reign of the family was handed over to Harumune. Is over.
Postwar processing of astronomical turbulence
1550 in Echigo due to the failure of the Uesugi family's adoption Uesugi Sadazane Died, Echigo guardian Uesugi was cut off, and guardian Nagao Keitora (Uesugi Kenshin) ruled Echigo It will be.
Due to the turbulence of the last 6 years, the power of Mr. Date, who was proud of the great power in the Tohoku region, will suddenly decline. Ashina, Soma, Mogami who were subordinate to Date Is independent taking advantage of the turbulence And expand the power. In particular, Ashina has grown into a daimyo that is on par with Date.
Also, Osaki / Kasai Then, the child of Tanemune who was sent to the adopted child was purged, and the house takeover plan ended in failure. Even within the Date clan, it took time to suppress the vassals of the Date clan, and the senior vassals took advantage of the turbulence to expand their power, becoming the largest power in the family and wielding power behind the scenes.
1564 , Date Terumune Was handed over from his father, Harumune.
However, the real power is Nakano parent and child who became the most powerful person in the house due to the retired father and the astronomical disturbance. Was held by. Therefore, 1570 to control the whole house. On the suspicion of rebellion at the time of Mune Nakano, he dropped his castle, Komatsu Castle, and succeeded in expulsion of Nakano's parents and children. At this time, Morimune Koyagawa, Munetoshi Shiraishi, Munetada Miyauchi were uncooperative with Terumune. Was punished.
In the same year, when a parent-child quarrel began with his wife's parents, Mogami, he sided with his father, Yoshimori, but his wife, Yoshihime, urged him to withdraw, so he pulled a soldier.
Terumune, who rejected Nakano's parents and children, succeeded in taking control of the whole family.
Terumune wipes out personnel affairs Yoshinao Oniwa Was selected as a rating role, and Motonobu Endo was a vassal of Mr. Nakano, the enemy. In anticipation of his talent, he took charge of diplomacy. The Terumune administration, centered on these two names, took over Harumune's policy and developed a wide range of diplomatic activities while maintaining a relationship with Ashina.
1575 In addition, the influential person at that time [ Oda Nobunaga Send a hawk to Hojo Ujimasa and Shibata Katsuie I also exchanged letters frequently with them to build a friendly relationship.
1578 Kenshin Uesugi Died, and when the house turmoil occurred, Terumune entrusted Mr. Soma to Watari Motomune and arrived at Uesugi Kagetora's side to participate in the war. However, Kagekatsu Uesugi won, and Ashina and the Date Army had no good points.
On the other hand, in the Soma battle, the battlefield was not good because Soma Moritane and Soma Moritane, who were good at the war, struggled. 1579 Kiyoaki Tamura 1582 , trying to cut down Mr. Soma by marrying his daughter, Megohime, to Masamune. Succeeded in the strategy of Kosai Castle owner, Tamenobu Sato.
1583 Finally, when the important issue, Marumori Castle, was regained, he reconciled with Mr. Soma, almost recovered the 11 counties of the sphere of influence since Tanemune, and had a great influence on Southern Tohoku.
Date Masamune's inheritance and two-headed system
1584 , Ashina Moritaka Terumune becomes the guardian of Moritaka's child, who is only one month old, when he is murdered by his vassals from the entanglement of lust. With this as a trigger, he handed over the family to Masamune and moved to Tateyama Castle with an eye on Echigo's intervention.
At this time, Terumune 41 years old, Masamune 18 years old It was that.
The retreat at the age of 41, which is still in full swing, is a two-headed system by the father of the former head and the son of the current head. It becomes a political system in. Governance under this system should be in the same direction for both of them, but once they disagree, it will lead to a house turmoil.
A person from Masamune couldn't be a decoration for his father, and he changed his foreign policy immediately after he inherited the family. Dissolve the alliance with Ashina who has maintained a friendly relationship until now And 1585 Invades Aizu.
There was a reason for this, because the Ouchi Sadatsuna, who followed the Date clan, disobeyed Masamune.
Masamune shoots the fixed rope and at the same time attacks Yoshitsugu Hatakeyama, who was supporting him. Yoshitsugu offers peace to the Date clan, but suddenly abducts Terumune, who was acting as an intermediary for negotiations.
Masamune, who was taken hostage by his father, started a counterattack. In the process of this attack, he shot and killed Yoshitsugu Hatakeyama with his father, Terumune, and at least went to Hatakeyama territory with that momentum. This action buys the antipathy of Ashina and Satake, and strengthens the conflict with Masamune.
Masamune calls it a mourning battle for his father and surrounds Hatakeyama's Nihonmatsu Castle, but with Satake at the top, Minamiokuba Union 30,000 large troops to rescue. The Date Army, which was overwhelmingly inferior in number, quickly rushed and retreated.
Even though it was a constant era after the conflict, it seems that the actions of shooting and killing the enemy with his father seemed to be overkill for the surrounding daimyo. In dramas, Terumune decided to [ shoot with me ], But this is a creation.
According to one theory, it was a planned rebellion by Masamune, who did not meet in foreign policy in a two-headed regime with his father. The truth is unknown, but the two-headed system that Date Terumune was thinking of will come to an end.
1586 In addition, Nihonmatsu Castle will be surrounded again as a revenge. In July, under the mediation of Mr. Soma, peace will be established on the condition that Mr. Hatakeyama surrenders the castle. As a result, Nihonmatsu territory became the territory of the Date clan.
After that, peace was reached again with the lords of the South Ou Union, including Mr. Satake, and peace came to the Tohoku region again, but it did not last so long.
I would like to write Date Masamune in the biography of this continuation and details, so I will write it in detail there.
