The so-called "butterfly effect" refers to an originally insignificant thing, but the result has caused a huge impact; although many people find it incredible, or far-fetched, but in history, this kind of thing is often happening, history, always inadvertently, by a small person or a small thing to change.
And here is the thing to say, this happened in Japan during the Sengoku period, originally just a very ordinary war, but it led to the fall of Oda Nobunaga at the peak of the period. In fact, this also begins with the deeds of a small family, which is the Hatano clan, the overlord of the Tanba kingdom.
After the "Ying Ren Rebellion", Hatano Hidenaga, the patriarch of the Hatano clan, was appointed as the guardian of the Tanba Kingdom for his merits, and Hatano Hidenaga's son Hatano Ueno Uedō was a brave and resourceful figure, who expelled the Guardian of the Tanba Kingdom during his reign, Naito Kunitada, thus dominating the country, and then presided over the construction of Yakami Castle, one of the ten strong castles of japan's Warring States period, as a residence castle, declaring to the world the wealth of Hatano's family's strength, material resources and financial resources.
The third generation of the Hatano family, Hatano Harutsu, although a weak and faint person, the fourth generation of the family lord Hatano Hideharu was a male lord; for some reason, this Wave Tano Hideharu looked down on Oda Nobunaga, or hated Oda Nobunaga, although he submitted to Oda Nobunaga after Oda Nobunaga successfully "went to Luo", but immediately betrayed Oda Nobunaga after the general Ashikaga Yoshiaki launched the "Nobunaga Siege Network".
However, Hideharu Hatano overestimated the strength of the "Nobunaga Encirclement Network" and underestimated the ability of Oda Nobunaga, and after six years, Oda Nobunaga not only broke the "Nobunaga Encirclement Network", but also increased in strength by leaps and bounds; after that, Oda Nobunaga began to liquidate those who had been his enemies, and the Hatano clan of The Tanba Kingdom was naturally among them, and because of the importance of the geographical location of the Tanba Kingdom, it was the focus of Oda Nobunaga.
But what Oda Nobunaga did not expect was that the powerful Asakura clan, Asai clan, Honganji clan, Miyoshi clan, Rokkaku clan, and even the Takeda clan and Uesugi clan all submitted or perished, but the poor and weak Hatano clan resisted tenaciously. At that time, it was Mitsuhide Who was in charge of attacking the Tanba Kingdom, who thought that it would be easy to attack the Tanba Diet, but did not expect that Hatano Hideharu used the terrain of The Tanbota Mountains to fight cage battles and guerrilla warfare with the Oda Army.
This caused great losses on the side of Wise Mitsuhide and the slow progress, which annoyed Oda Nobunaga, so he dispatched Niwa Nagahide and Ikeda Tsuneyuki from to cooperate with Wise Mitsuhide's actions, but the results were still not ideal; Oda Nobunaga had no choice but to give Wise Mitsuhide a one-year ultimatum, and Wise Mitsuhide had no choice but to turn to Hashiba Hideyoshi (Toyotomi Hideyoshi), who was good at intrigue and trickery.
The Tanba Kingdom was only a small country, and its territory was about 260,000 stones, which was only 70,000 or 8,000 troops at most, but at this time, Oda Nobunaga gathered more than 50,000 soldiers in the Danbo Kingdom, so Hatano Hideharu decided to shrink his forces and concentrate on defending Yakami Castle. These eight upper castles are really worthy of being a fortified city built by Hatano Ugetsu with the strength of the country, even if the enemy is several times or even ten times more than himself, it is still impregnable.
Even Hashiba Hideyoshi was poor in the face of such a strong castle, and had no choice but to adopt the tactic of encircling and not attacking, trying to trap the hellish forces in the city; time was rising, time was like an arrow, and more than a year had passed; the year that Oda Nobunaga had set, Mitsuhide was very anxious, and he hoped more than anyone that Hatano Hideharu would surrender quickly, so he also sent his mother into the city as a hostage.
In fact, there was a shortage of food in the city, and Hatano Hideharu saw that Mitsuhide was so sincere, so he decided to surrender, and went to Azuchi Castle with his brother Hatano Hideyoshi to apologize to Oda Nobunaga, Oda Nobunaga promised that they would still be the daimyō of Tanba Domain; but before long, Oda Nobunaga thought more and more, and it was clear that Hatano Hideharu had betrayed himself and wasted so much of his time and material resources, so he sent someone to kill Hatano Hideharu and his family.
The destruction of the Hatano clan made the courtiers loyal to the Hatano clan angry, believing that Mitsuhide had deceived them, so they brutally killed Mitsuhide's mother. Although Mitsuhide later killed all the gang, he still could not calm the hateful heart of Mitsuhide, he felt that Oda Nobunaga did not keep his word, resulting in the killing of his mother, the so-called revenge of killing his mother, not sharing the heavens.
It was from this moment that the seed of hatred was deeply buried in the heart of Mitsuhide Akira, and this seed, under the irrigation of other factors, eventually grew into a towering tree, triggering the "Change of Honnoji Temple"; "Honnoji Change" was definitely a major event that affected the Japanese Sengoku and the history of Japan, and the ambitious Oda Nobunaga, who was at the peak of his time, died in the rebellion of his subordinate Mitsuhide Akira.
