It is said that "tiger father has no dog", but this statement seems a little inappropriate to use on Oda Nobunaga; I don't know if it is because Oda Nobunaga has exhausted the luck of the Oda clan, and the sons who have been born have died early, and the rest are not out, such as the one to be said next, it is simply a waste, and it is a waste of Oda Nobunaga's back road for him.
This son was Oda Nobunaga's second son, Oda Nobunaga, and although there was a male in his name, Oda Nobunaga was clearly a sinister and cunning man; although he was the second son, Oda Nobunaga still had a lot of affection for this son, so when attacking the Kitahata family, Oda Nobunaga was used as the heir of Kitahata Kufu and married the daughter of Kitahata Kushi as a condition for harmony.
This Kitabata family was the overlord of the Ise Kingdom, which was one of the thirteen great powers of Japan at that time, with a territory of about 600,000 stones high, and it was close to the Gyeonggi region, with developed agriculture, forestry and aquaculture, and the country was rich and strong; it can be seen that Oda Nobunaga arranged Oda Nobuo in this way, that is, he hoped that Oda Nobuo would become the gatekeeper of the Oda clan in the future.
At first, Oda Nobuo did the same, and after inheriting the Hokusaka family governor, he not only killed his father-in-law Kita hata and Hokuba Ichimon, but also forced his wife Chiyo Gozen to commit suicide, and the Kita hata clan was severed, and Oda Nobuo has since completely gained the power of the Kita family and become the overlord of the Ise kingdom.
But Oda Nobuo's military prowess disappointed Oda Nobunaga; why? Because Oda Nobuo was not satisfied with the power of the Ise Kingdom, he attacked the Iga Kingdom without Oda Nobunaga's permission. Although the Iga kingdom and the Ise kingdom are next to each other, the difference in national strength is extremely large, and the Iga kunishi is about 100,000 stones high, that is to say, the difference in strength between the two sides is as much as six times.
Although this Iga Kingdom was small, it was not weak at all, because the Iga Stream of the two major ninja schools was in the Iga Kingdom, so when Oda Nobuo attacked strongly, the Iga Stream ninjas rarely united together to resist Oda Nobuo's army with the rest of the Iga Kingdom; and the Iga people were fierce, not only the land was all bastioned, but also the whole people were soldiers, so Oda Nobuo was defeated and defeated.
Although Oda Nobunaga reprimanded him, as a father, he still chose to stand up for his son, and for a while, the Oda family's large armies gathered near the Iga Kingdom and invaded the Iga Kingdom from all directions, this time the leading generals in addition to Oda Nobunaga, there were also famous generals such as Takikawa Kazuyoshi and Kabuo Clan, although the Iga Kingdom was brave, it was a small country after all, and eventually perished.
After Oda Nobunaga's death at Honnō-ji Temple, he was appointed protector of the third mage Oda Hidenobu, but when Toyotomi Hideyoshi fought with Shibata Katsuya, he sided with Toyotomi Hideyoshi and attacked his younger brother Oda Nobutaka, who was at Gifu Castle because of a dispute over his heirs, and later committed suicide after Oda Nobuhito surrendered, which was one of the stupidest decisions Oda Nobuo made in his life.
The second stupid decision he made was that after the demise of the Shibata Katsuya, he did not choose to defect to Toyotomi Hideyoshi in time, but instead opposed to Toyotomi Hideyoshi, whose power was rapidly expanding; if he had turned to Toyotomi Hideyoshi at that time, with Toyotomi Hideyoshi's generosity, he might have gained a lot.
But he was not useless, for example, after he knew that he was not a rival of Toyotomi Hideyoshi, he found his father's best ally, Tokugawa Ieyasu, and Tokugawa Ieyasu was indeed willing to help him; because Oda Nobuo and Tokugawa Ieyasu's alliance had a tactical advantage, and therefore matched to Toyotomi Hideyoshi, who had overwhelming combat strength, the war became a stalemate.
As a result, the confused Oda Nobuo made the third stupid decision in his life; the situation of the war was originally favorable to the combined forces of Oda Nobuo and Tokugawa Ieyasu, but in the end Oda Nobuo privately accepted the terms of the peace talks offered to him by Toyotomi Hideyoshi, betrayed Tokugawa Ieyasu and made peace with Toyotomi Hideyoshi, thus ending the war. When it was really a strength to pit allies, the most iron brother of his father's life, Tokugawa Ieyasu had a word of suffering.
Toyotomi Hideyoshi did not embarrass him, but later after the Kyushu Conquest, he was appointed as the Minister of the Interior; but this brain cramped again, after the Odawara War, the Hojo clan was destroyed, and Toyotomi Hideyoshi was already dominating Japan; Toyotomi Hideyoshi began to make personnel adjustments, and Oda Nobuo was transferred to Suruga Kingdom, which was the headquarters of the former Imakawa clan, but was not as rich as The Ise Kingdom, so Oda Nobuo refused.
Toyotomi Hideyoshi was furious, thinking that he was "killing chickens for monkeys" with this brainless guy, so he was stripped of his fiefdom and forced to leave his home and live under house arrest from then on; it was not until Toyotomi Hideyoshi prepared to attack Korea that he was pardoned and given several territories; at the same time, his eldest son, Oda Hideo, was also summoned and given 50,000 stones on Echizen Kameyama.
After all, Toyotomi Hideyoshi is still a person who remembers the old favor, and he was indeed not kind at the beginning, because he did not want to change the title, he cut people to the end, which was really too cruel. Years of house arrest have finally made Oda Nobuo a little smarter, and during the Sekigahara War, he helped both sides, on the one hand, supporting Ishida Sansei's actions, but on the other hand, he sent Kiuchi intelligence to Tokugawa Ieyasu.
Later, he served as an official in the Toyotomi family, but left Toyotomi Hideyoshi during the Osaka Winter Front and moved from Osaka to Kyoto; Tokugawa Ieyasu was also confused about what he had done, and the resentment in his heart for him had long since dissipated during the years when he was under house arrest, and perhaps thanked him; perhaps out of gratitude for the Oda Nobunaga who had helped him a lot, the Tokugawa family awarded him 20,000 stones to Ueno Kuni and 30,000 stones to Yamato Kuni.
At this time, the elderly Oda Nobuo was also very alive, and he did not bother to return to the fiefdom, directly spent the rest of his life in the bustling city of Kyoto, and never participated in political affairs, studying tea art and song and dance drama all day, and thus became a celebrity in Kyoto at that time; because of this, when the Tokugawa family cleaned up the lords of the domain, he did not bother to move him, and there was no reason to move him, and finally his two sons became the lords of the domain, which was also a good ending.
