==== The birth of the first warrior class government ====
{{Further|Taira no kiyomori|Genpei War}}
[[File:Taira no Kiyomori Portrait by Fujiwara Tamenobu and Takenobu.png|thumb|left|[[Taira no Kiyomori]] was the first person born of the warrior class to rise to the highest rank of nobility and the first to establish a de facto samurai government.<ref name="nhkgenpei"/>]]
During the reigns of [[Emperor Shirakawa]] and [[Emperor Toba]], the [[Taira clan]] became {{nihongo3||国司|[[Kokushi (official)|Kokushi]]}}, or overseers of various regions, and accumulated wealth by taking samurai from various regions as their retainers. In the struggle to succeed Emperor Toba, former [[Emperor Sutoku]] and [[Emperor Go-Shirakawa]], each with his samurai class on his side, fought the [[Hōgen rebellion]], which was won by Emperor Go-Shirakawa, who had [[Taira no Kiyomori]] and [[Minamoto no Yoshitomo]] on his side. Later, Taira no Kiyomori defeated Minamoto no Yoshitomo in the [[Heiji rebellion]] and became the first samurai-born aristocratic class, eventually becoming {{nihongo3|Chancellor of the Realm|太政大臣|daijō-daijin}}, the highest position of the aristocratic class, and the Taira clan monopolized important positions at the imperial court and wielded power. The seizure of political power by Taira no Kiyomori was the first instance of the warrior class leading politics for the next 700 years.<ref name="nhkgenpei">{{cite web|url=https://www.nhk.or.jp/kokokoza/nihonshi/assets/memo/memo_0000000570.pdf|archive-url=https://web.archive.org/web/20240314105156/https://www.nhk.or.jp/kokokoza/nihonshi/assets/memo/memo_0000000570.pdf|script-title=ja:平氏政権の登場|language=ja|publisher=[[NHK]]|date=|archive-date=14 March 2024|access-date=14 March 2024}}</ref>

However, when Taira no Kiyomori used his power to have the child of his daughter [[Taira no Tokuko]] and [[Emperor Takakura]] installed as [[Emperor Antoku]], there was widespread opposition.
[[Prince Mochihito]], no longer able to assume the imperial throne, called upon the [[Minamoto clan]] to raise an army to defeat the Taira clan, and the [[Genpei War]] began. In the midst of the Genpei War, [[Minamoto no Yoshinaka]] expelled the Taira clan from Kyoto, and although initially welcomed by the hermit Emperor Go-Shirakawa, he became estranged and isolated due to the disorderly military discipline and lack of political power under his command. He staged a coup, overthrew the emperor's entourage, and became the first of the Minamoto clan to assume the office of {{nihongo3|shogun||Sei-i Taishōgun}}. In response, [[Minamoto no Yoritomo]] sent [[Minamoto no Noriyori]] and [[Minamoto no Yoshitsune]] to defeat Yoshinaka, who was killed within a year of becoming shogun. In 1185, the Taira clan was finally defeated in the [[Battle of Dan-no-ura]], and the Minamoto clan came to power.<ref name="nhkgenpei"/><ref name="sarai030422">{{cite web|url=https://serai.jp/hobby/history/1055058|archive-url=https://web.archive.org/web/20231201070617/https://serai.jp/hobby/history/1055058|script-title=ja:頼朝のライバル木曽義仲がた辿った生涯と人物像に迫る 源平合戦で活躍したその武略とは？|language=ja|publisher=[[Shogakukan]]|date=3 April 2022|archive-date=1 December 2023|access-date=13 March 2024}}</ref>
