Yoshitsura Isshiki

Japanese: 一色義貫 - いっしき・よしつら

Year of death: May 15, 12th year of Eikyo (June 14, 1440)
Year of birth: 1400
A military commander in the Muromachi period. Son of Isshiki Mitsunori. First named Yoshinori. Served as Hyobu Shoyu, Sakyo no Daifu, and Shuri no Daifu. At the age of 10, he succeeded the position of Shugo of three provinces, Wakasa (Fukui Prefecture), Mikawa (Aichi Prefecture), and Tango (Kyoto Prefecture), after his father's death. He served as the head of the Samurai Department for seven years from 1414, and in 1419 was appointed commander-in-chief of the army to subjugate the Kitabatake clan in Ise (Mie Prefecture). His success in the central political world was due in large part to the support of senior vassals such as the Mikata and Nobunaga clans. In 1430, during the procession accompanying the Shogun Ashikaga Yoshinori's congratulations on his appointment as Udaisho (right general), he strongly desired to lead the vanguard, but this was not accepted and he was placed second. Yoshitsune considered this a "disgrace to his family" and did not participate on the day, claiming to be ill, and even indicated his readiness to fight and commit seppuku if the assassins came. In the end, he was not punished, and was subsequently appointed as the head of the Samurai Office, but in the 12th year of the same year, during a campaign in Yamato (Nara Prefecture), he was assassinated by Takeda Nobuhide, who received secret orders from Yoshinori. Although the position of Tango Shugo among his remaining territories was inherited by his nephew, Norichika, the influence of the Isshiki clan declined significantly thereafter. <References> Obama City History/General History Volume 1

没年：永享12.5.15(1440.6.14)
生年：応永7(1400)
室町時代の武将。一色満範の子。初名義範。兵部少輔,左京大夫,修理大夫。父の死により10歳で若狭(福井県)・三河(愛知県)・丹後(京都府)の3カ国守護職を継ぐ。応永21(1414)年から7年間侍所頭人を務めたのをはじめ,同22年には伊勢(三重県)北畠氏討伐軍の総大将に任じられるなど中央政界で活躍できたのは,三方氏,延永氏ら重臣の支えに負うところが大きい。永享2(1430)年,将軍足利義教の右大将拝賀式の供奉行列に際しては先陣を務めることを強く望むが容れられず,2番目に配された。これを「家の恥辱」とした義貫は当日,病気と称して参加せず,討手が来れば一戦交えて切腹する覚悟まで示した。結局処罰はなく,その後も侍所頭人に任じられたりしているが,同12年の大和(奈良県)出陣中,義教の密命を受けた武田信栄により謀殺された。遺領のうち丹後守護職などは甥の教親に継承されたものの,以後一色氏の威勢は著しく衰えることになる。<参考文献>『小浜市史/通史編』上
