Ikeda Incident - Ikeda Incident

In 1640 (Kan'ei 17), a family dispute occurred within the household of Ikeda Teruzumi, a fudai feudal lord and feudal lord of the Yamazaki domain in Harima province (Hyogo prefecture) with a stipend of over 68,000 koku. In 1615 (Genwa 1), the Ikeda clan of the Harima Himeji domain split into three branch domains: Yamazaki (Ikeda Teruzumi, 38,000 koku), Ako (Ikeda Masatsuna, 35,000 koku), and Hirafuku (Ikeda Teruoki, 25,000 koku). Of these, the Masatsuna family died out without an heir in 1627 (Kan'ei 4), and the Teruoki family went insane in 1645 (Shoho 2) and was stripped of their title. In 1631 (Kan'ei 8), Terusumi was granted an additional 30,000 koku in Masatsuna's former territory of Sayo County in Harima, giving him a total of 68,000 koku. However, Terusumi favored a newcomer, Ogawa Shirouemon, and caused a dispute with his elder retainer, Igi Iori. Igi and over 100 others fled the domain, and the shogunate intervened to punish both factions. Terusumi was demoted and entrusted to his clan's Inaba Tottori domain, where he received 10,000 koku as compensation for his patience.

1640年（寛永17）播磨(はりま)国（兵庫県）山崎藩6万8000石余の領主、譜代(ふだい)大名池田輝澄(てるずみ)の家中に起こった御家騒動。1615年（元和1）播磨姫路(ひめじ)藩池田氏は山崎（池田輝澄、3万8000石）、赤穂(あこう)〔池田政綱(まさつな)、3万5000石〕、平福(ひらふく)〔池田輝興(てるおき)、2万5000石〕の3支藩に分かれた。このうち、政綱家は1627年（寛永4）嗣子(しし)なく断絶、輝興家は1645年（正保2）狂気して改易となった。輝澄は1631年（寛永8）政綱の旧領播磨佐用(さよ)郡の3万石余の加増を得て6万8000石を領有した。しかるに輝澄は新参の小河(おがわ)四郎右衛門を重用し、家老伊木伊織(いぎいおり)と紛議を起こした。伊木ら100余人は脱藩するに至り、幕府はこれに介入して両派を処罰するとともに、輝澄は改易、一族の因幡(いなば)鳥取藩に預けられ、その堪忍(かんにん)分として因幡鹿野(しかの)1万石を得た。
