Editing Sengoku period (section)

== Background ==
During this period, although the [[Emperor of Japan]] was officially the ruler of the state and every lord swore loyalty to him, he was largely a marginalized, ceremonial, and religious figure who delegated power to the ''[[Shogun|shōgun]]'', a noble who was roughly equivalent to a [[Military dictatorship|military dictator]].

From 1346 to 1358, during the [[Nanboku-cho period]], the Ashikaga shogunate gradually expanded the authority of the {{nihongo3||守護|[[Shugo]]}}, the local military and police officials established by the [[Kamakura shogunate]], giving the ''Shugo'' jurisdiction over land disputes between {{nihongo3||御家人|[[gokenin]]}} and allowing the ''Shugo'' to receive half of all taxes from the areas they controlled. The ''Shugo'' shared their newfound wealth with the local samurai, creating a hierarchical relationship between the ''Shugo'' and the samurai, and the first early {{nihongo3|feudal lords|大名|[[daimyo]]}}, called {{nihongo3||守護大名|shugo daimyo}}, appeared.<ref name="shugosen">{{cite web|url=https://www.touken-world.jp/history/history-important-word/shugodaimyo-sengokubusho/|archive-url=https://web.archive.org/web/20240317181933/https://www.touken-world.jp/history/history-important-word/shugodaimyo-sengokubusho/|script-title=ja:守護大名と戦国武将|language=ja|publisher=The Japanese Sword Museum Nagoya Touken World|date=|archive-date=17 March 2024|access-date=17 March 2024}}</ref>

In 1428, [[Ashikaga Yoshimochi]], the fourth shogun, was ill and the question of his succession arose. [[Ashikaga Yoshikazu]], the 5th shogun, died of illness at the age of 19, so the 6th shogun was chosen from among Yoshimochi's four brothers, and to ensure fairness, a lottery was held. The sixth shogun was [[Ashikaga Yoshinori]]. But he was not educated to be a shogun, and his temperamental and despotic behavior caused resentment. [[Akamatsu Mitsusuke]] assassinated him during the [[:ja:嘉吉の乱|Kakitsu Rebellion]]. This led to instability in the Ashikaga shogunate system. The shogunate gradually lost influence and control over the ''daimyo''.<ref name="kyoto260523">{{cite web|url=https://www2.city.kyoto.lg.jp/somu/rekishi/fm/nenpyou/htmlsheet/toshi14.html|archive-url=https://web.archive.org/web/20230526102155/https://www2.city.kyoto.lg.jp/somu/rekishi/fm/nenpyou/htmlsheet/toshi14.html|script-title=ja:応仁・文明の乱|language=ja|publisher=Kyoto City|date=|archive-date=26 May 2023|access-date=14 March 2024}}</ref><ref name="nagoyaka">{{cite web|url=https://www.touken-world.jp/history/history-important-word/kakitsu-no-ran/|archive-url=https://web.archive.org/web/20240314154053/https://www.touken-world.jp/history/history-important-word/kakitsu-no-ran/|script-title=ja:嘉吉の乱|language=ja|publisher=The Nagoya Japanese Sword Museum Nagoya Touken World|date=|archive-date=14 March 2024|access-date=14 March 2024}}</ref>
