Prestigious Imagawa
When the Muromachi Shogunate was established, Ashikaga Takauji and Naoyoshi When Takauji was in conflict, the Suruga Imagawa family was attached to Takauji, and the Inaba Imagawa family was attached to Naoyoshi.
Yoshimitsu Ashikaga In his place, he was suspected of initiating a dispute between the Kantō Kubō and the shogun family, was alienated from the central political world, and was deprived of half the guardianship of Totomi. However, it was later decided to hand over the Totomi Peninsula to Mr. Shiba.
Mr. Imagawa's reign of the family
Yoshitada Imagawa during the Onin War When he died, his firstborn, the Ryuomaru faction, and his younger brother, the Oshika Norimitsu faction, confronted each other over the family reign. At this time, Hojo Soun (Ise Somizu) , who is Yoshitada's uncle. Will enter the mediation and will take this place.
At this time, Hojo Soun said, [ Norimitsu Oshika will act as the reign of the family until Ryuomaru grows up . ], And both sides agreed, but even when Ryuomaru was 17 years old, Norimitsu did not try to give up the family. So, in 1487, Hojo Soun attacked Sunpu Castle and purged the Oshika Norimitsumon.
Ryuomaru, who played a genpuku with the success of Sakumo, is Imagawa Ujichika . It manages the operation of the territory next door. The Imagawa and Hojo families cooperated with each other, such as sending reinforcements to the battle of Soun in the Kanto region without forgetting the grace of Hojo Soun.
Ryuomaru's mother is Hojo Soun's younger sister, and it is said that this intermediary play was realized when her younger sister, Kitagawa-dono, worked on Soun.
Imagawa Kana Mokuroku
The Bunkokuho enacted by Mr. Imagawa was enacted by his parents in 1526 [ Kana Mokuroku ] And his child, Yoshimoto [ Kana Mokuroku added ] Is a combination of both [ Imagawa Kana Mokuroku ].
1526 At that time, Ujichika was in bed, and it was characterized by the opinions of his wife and vassals who wanted to stabilize the administration rather than the house law. The content is judgment criteria such as proceedings regarding land, etc. rather than retaining the power of the Sengoku daimyo. The feature is that the color is strong.
In addition, 1553 Yoshimoto Imagawa Will be added to all 21 articles, Kana Mokuroku added Has been enacted and added to conflicts and inheritance between vassals. In particular, he denied the non-protection mandated by the Muromachi Shogunate and willing to completely shift from a guardian daimyo to a warring lord . Is the feature.
It also includes provisions such as protection for dependents, and some are similar to the current social security system.
Imagawa Ujichika and the rise of Hojo Soun
Originally, Mr. Imagawa had served as a guardian in Totomi, but he remained robbed by Mr. Shiba.
This recapture of Totomi was a long-cherished wish of his father, Yoshitada, and his parents, who became the head of the family, often marched on Totomi to fulfill their long-cherished wish.
Mainly, it was Mr. Imagawa's vassal who led the soldiers to Totomi Hojo Soun (at that time Somizu Ise) So, 1494 By that time he had expanded his power to the central part of Totomi. 1501-1504 In, he attacked Mr. Matsudaira of Mikawa Iwazu Castle, and his parents also cooperated in the expedition for the advancement of Sayaun into the Kanto region, and fought together the turbulence of longevity.
Since 1509, Sakumo has ceased to be active as the Imagawa family, and it seems that he has achieved independence, and Sakumo's advance into the Kanto region will begin in earnest.
Shogun Ashikaga Yoshitane When Ujichika regained his post as a shogun, his parents supported the shogun and officially appointed him as a Totomi guardian from the shogunate. And got the cause of Totomi rule. Still, the conflict with Mr. Shiba will intensify.
1516 At the same time, Sadatsuna Okouchi of Hamamatsu Castle betrayed, and Imagawa Ujichika surrounded the castle and surrendered it.
As a result, Totomi was settled.
1515 On the side of the people of the western part of Kai, the guardian Nobutora Takeda Temporarily occupied Katsuyama Castle. 1517 When the Kokujin surrendered to Nobutora Takeda, he concluded a consensus and pulled soldiers, but the confrontation with Mr. Takeda continued until the Koshun Alliance was formed.
After 1518, Imagawa Ujichika, who had the entire Totomi territory as a territory, focused on domestic affairs, conducted land inspections, developed Abe Kanayama, and strengthened his financial strength. By marrying Jukei-ni, who was from a public family, the culture of Kyoto was introduced into his territory, and his parents themselves enjoyed waka poems and renga.
The appearance of Yoshimoto Imagawa
Imagawa Ujichika Yoshimoto, who was born as the fifth son of Imagawa Ujiteru, has already succeeded Ujiteru . He was sent to the Buddhist gate at the age of four. After that, he was recalled to Ujiteru and returned to Shunfu, but in 1536, Ujiteru and Hikogoro, who had the right to succeed, died one after another.
Hanakura Ran in a family battle between Yoshimoto and his half-brother When he won the position of the head of the Imagawa clan, he set up a control system centered on the vassals who showed loyalty to himself.
Yoshimoto is Nobutora Takeda , who has been in conflict since the time of Imagawa Ujiteru. Takeda and Koshun Alliance Was tied. It was the opponent of the Shun-so alliance Hojo Ujitsu who disagreed with this alliance. As a result, the relationship with Mr. Hojo deteriorated, and he was forced to advance to the eastern part of Suruga.
I hope to regain the eastern part of Suruga with Mr. Takeda's reinforcements, but I could not regain the eastern part of Suruga due to the anti-Imagawa faction of Mr. Horikoshi and Mr. Ii. In addition, Owari's Oda Nobuhide should be revenge. Invades the eastern part of Mikawa, and Yoshimoto defeats Mikawa, but is defeated before the Oda army.
1541 Nobutora Takeda was banished to Harunobu, and when Harunobu succeeded his family, Nobutora was entrusted to the Imagawa clan. Harunobu will later become Takeda Shingen, but the alliance will continue and 1545 In the Siege of Takato, we are sending reinforcements to the Takeda army.
At that time, Mr. Hojo died, and Mr. Ujiyasu succeeded the family, but the relationship between Mr. Imagawa and Mr. Hojo remained poor. Yoshimoto Imagawa teamed up with Norimasa Uesugi, the Kanto governor, to counter Hojo Ujiyasu 1545 I attacked Mr. Hojo.
Furthermore, Harunobu Takeda (Shingen) At the same time as the Imakawa Allied Forces marched in the direction of the eastern part of the river, the Uesugi family and Ashikaga Haruuji Surrounds Kawagoe Castle in the Kanto region with 80,000 troops and is in a difficult situation. Therefore, Hojo Ujiyasu asked Harunobu Takeda to act as an intermediary and applied for a consensus on the condition that he would return the Kato that he had stolen from Mr. Imagawa.
After a consensus was reached, Hojo Ujiyasu was able to concentrate on the Kanto area and win the battle at Kawagoe Castle.
In the direction of Mikawa in the west, Hirotada Matsudaira returned to the Imagawa family and Inu Chiyo (Motoyasu Matsudaira) was welcomed as a hostage. However, Yasumitsu Toda of Mikawa, who was escorting Inu Chiyo, betrayed and sent a hostage to his nemesis, the Oda clan. With this event, Nobunaga Oda and Ieyasu Tokugawa I get acquainted when I was young.
1548 Nobuhide Oda has progressed to Mikawa, but thanks to the activities of the Imagawa clan Sessai Choro and his senior vassal, Yasunori Asahina, he has succeeded in expelling the Oda clan from Mikawa. As a result, the Imagawa family is Mikawa / Totomi / Suruga . It has come to rule the territory of 690,000 stones in the three countries of.
1549 When Hirotada Matsudaira of Okazaki Castle died, he effectively controlled Okazaki Castle, where the castle owner was absent, and the former territory of the Matsudaira family was also controlled by the Imagawa family. At the same time, he succeeded in attacking the remaining Mikawa territory of the Oda clan and capturing Nobuhiro Oda. I applied for the exchange of the captured Nobuhiro and the sent dog Chiyo, succeeded in regaining Mr. Matsudaira's firstborn, and succeeded in capturing the hearts of the Matsudaira family's vassals.
1551 In addition, when Nobuhide Oda died, Yoshimoto Imagawa began to capture Owari in earnest.
First of all, in order to mourn his patronage, he marries his daughter to Takeda Shingen's firstborn, Yoshinobu. In addition, his firstborn, Imagawa Ujizane, was made to have the daughter of Hojo Ujiyasu, and Koso Shun Trilateral Alliance Was established.
On the domestic affairs side, we conducted a territorial inspection and wrote the Imagawa Kana Mokuroku earlier. In addition, the old relationship between the Shogunate as a guardian daimyo and the Imagawa family was cut off.
1558 By that time, it is said that Yoshimoto himself retired after handing over his reign to Ujizane, which is considered to be a stepping stone to move to Tokyo. Then, in June 1560, Yoshimoto himself led a large army and invaded Owari, Battle of Okehazama . Begins.
Imagawa's decline and afterwards
Yoshimoto Imagawa in the Battle of Okehazama Was defeated, and Ujizane succeeded the Imagawa family.
Taking advantage of the turmoil of the battle, at Okazaki Castle in Mikawa, Matsudaira Motoyasu However, he became independent from the Imagawa clan and caused a turmoil in the territory controlled by Imagawa, and the people of Mikawa also separated one after another. Ujizane also goes out on his own and launches a conquest battle, but suffers a great defeat to the Matsudaira army and loses control of Mikawa.
The Imagawa clan continued to have bad luck, and a firstborn alliance was formed with Shingen Takeda's firstborn, Yoshinobu, but 1565 . The rebellion of Yoshinobu was discovered, and Reisho-in was repatriated to Mr. Imagawa, and the alliance deteriorated.
Takeda Yoshinobu Due to the abandonment of the fourth son, Katsuyori Suwa Was the mark, and Oda Nobunaga's adopted daughter was greeted in the concubine, and gradually began to show a hostile attitude with the Imagawa family.
1568 Finally, Shingen Takeda is Ieyasu Tokugawa (Motoyasu Matsudaira) Formed an alliance with and started invading the Imagawa territory, Suruga. Mr. Hojo joined Mr. Imagawa in the invasion of Suruga by Shingen Takeda, and the Koso Alliance also collapsed.
Imagawa Ujizane, who was driven into Totomi by cutting Mikawa and Suruga from the east and west in a blink of an eye, surrendered the last fort Kakegawa Castle to Ishikawa Ienari of the Tokugawa family, and with Asahina Yasutomo to Odawara. P>
In this way, Mr. Imagawa as a Sengoku daimyo will be destroyed in just eight years from the battle between Okehazama.
Imagawa Ujizane, who relied on Hojo, will live until 1615 under the patronage of Ieyasu Tokugawa. Imagawa Ujizane's firstborn, Naofusa, is a Koke * of the Shogunate. Hidetada / Iemitsu / Ietsuna For three generations, he worked hard to negotiate with the imperial court.
