He became the son-in-law of the oil merchant Naraya, and began to enter and leave the Saito family in Mino through business, and his vassal Hidehiro Nagai I became friends with. Hidehiro loved Shogoro and succeeded him as the adopted child of his vassal, Saburo Nishimura Saemon, Kankuro Nishimura . I collected it as.
Hidehiro Nagai When he died in a battle, his firstborn, Nagahiro, succeeded the family and became Saito's chief vassal.
From that time on, Kankuro Nishimura Has emerged in the Nagai family, and Nagahiro, who bought that talent, is the guardian Yoritake Toki . I brought Kankuro to.

At this time, I received the surname Nagai [ Shinzaemon Nagai ].
He made an outstanding performance in the battle for Toki's family, 1525 . He defeated his firstborn, Toki Yoritake, and greatly contributed to his appointment as a guardian of Yorinari.
The appearance of Dosan Saito and the unification of Mino
1533 In the document of that time, in collaboration with Lieutenant Shinzaemon Nagai, [ Norihide Fujiwara ] Name is written.
This is Dosan Saito, and it will appear around this time. According to the study, at the same time, his father, Lieutenant Shinzaemon, disappeared, and it is believed that Dosan inherited the will of his father.

Exile Toki Yorinari and Yoritsugu to Owari, effectively dominating Mino. In this way, Dosan was able to take control of Mino, which he had longed for, and became a Sengoku daimyo.
It is easy to understand by looking at the figure.
Alliance with Mr. Oda and Marriage of Nobunaga
Toki Yorinari exiled from Mino Is Owari's Oda Nobuhide I relied on Mino to launch repeated attacks on Mino.
Also, Asakura Takakage in Echizen Yorizumi Toki who was under the patronage of In cooperation with Saito Dosan Is in trouble. In this capture, Yorinari succeeded in seizing Ibi Northern Castle in the northwest of Mino. To do.

At this time, his daughter, Nohime, was Oda Nobuhide's firstborn, Nobunaga . By marrying him, Dosan was able to avoid a conflict with Mr. Oda. The marriage of the Saito and Oda families is Masahide Hirate , who is also Nobunaga's grandfather. It seems that it was largely due to the work of.
There is a famous anecdote at Shotokuji Temple where Dosan and his son-in-law Nobunaga met for the first time, but in this behavior of Nobunaga, Dosan himself said that my vassals would eventually become Nobunaga's servants. that's right. In historical fact, it's exactly what Dosan says.
After the meeting with Nobunaga, with the support of the Oda clan, 1552 Toki Yorinari of the Northern Castle Is banished to Owari again and Mino is settled.
Saito Yoshitatsu's coup d'etat and Dosan's death
Yoshitatsu Saito Her mother, Miyoshino, was originally a concubine of Toki Yorinari and later became a concubine of Dosan Saito. It was rumored that Yoshitatsu was a child of Toki Yorinari because Miyoshino was born soon after he married Dosan.
In the Saito family, the repulsion of Toki's old vassals was strong, and Dosan himself was having a hard time. So 1554 Yoshitatsu became the owner of Inabayama Castle in order to hand over his reign to Yoshitatsu and to accommodate Toki's old vassals.
However, this retreat was only a form, and the real authority was in Dosan, and since he loved Yoshitatsu's younger brother, Seishitsu's child, Dosan treated Yoshitatsu as incompetent and eventually abolished it. It seems that he was even thinking about getting angry.
Yoshitatsu, who was dissatisfied with Dosan's behavior, was 1555 . To his uncle Michitoshi Nagai And murdered and decided to subdue Saito Dosan. At this time, the later Mino Triumvirate, Ujiie Naotomo, Inaba Yoshimichi, Ando Morinari The former Toki clan's vassals were on the side of Yoshitatsu, so Dosan requested Oda Nobunaga for reinforcements.

His son-in-law, Nobunaga Oda, hurriedly sent out reinforcements in a pinch of his son-in-law, but Dosan was killed in time.
The Saito family after that
After the battle, Yoshitatsu Saito Has put together Mino Province, which has been confused by the civil war for many years, and succeeded in putting together the Saito clan, which could not be realized by the Dosan administration, while adopting a collegial system by the shukuro in the domestic affairs.
After Dosan's death, Kita Omi's Azai Hisamasa We will try to expand the power of the battle, but at this timing, Nobunaga Oda's invasion of Mino became fierce and we could not expand the power. Unlike Dosan, Yoshitatsu was a good organizer of the Saito family, but died in 1561 at the young age of 35.
After that, Tatsuoki Saito However, due to the invasion of the Oda clan and the outflow of old vassals, 1567 The Saito family as a warring lord will be destroyed in the battle of Mt. Inaba.
