Ikoma Incident - Ikoma Incident

A family turmoil occurred in the Ikoma family, lords of Takamatsu Domain in Sanuki Province (Kagawa Prefecture). The fourth lord, Takatoshi, inherited the family headship at a young age, so his maternal grandfather, Todo Takatora, served as his guardian. Senior vassals Maeno Sukezaemon and Ishizaki Wakasa gained favor with Takatora, ousted the national elder Ikoma Shogen, and seized power as Edo elders. Furthermore, they took advantage of the fact that Takatoshi's wife was the daughter of the Shogunate elder councilor Doi Toshikatsu, and ran the country as they pleased in Toshikatsu's name. In response to this, his son Tatewaki, who succeeded Shogen after his death, filed a complaint against Maeno and Ishizaki for their tyranny in 19 articles and filed a lawsuit against the Shogunate in 1637 (Kan'ei 14). After several investigations at the Hyojosho (council of judges), the Ikoma clan's land was confiscated, and Takatoshi was transferred to Yajima in Dewa Province (Akita Prefecture) with a fief of 10,000 koku. Maeno and Ishizaki were forced to commit seppuku, and their allies were sentenced to death. In contrast, Obito was made the custodian of the Matsue domain, and the case was settled with light punishment for the opponents.

讃岐(さぬき)国（香川県）高松藩主生駒家で起こった御家(おいえ)騒動。4代藩主高俊(たかとし)は幼少で家督相続をしたため、外祖父藤堂高虎(とうどうたかとら)が後見役を務めていた。重臣前野助左衛門、石崎若狭(わかさ)は高虎に取り入り、国家老の生駒将監(しょうげん)を排し江戸家老として権力を握った。さらに、高俊の内室が幕府老中土井利勝(どいとしかつ)の娘であることを利用し、利勝の名のもとに国政をほしいままに行うに至った。これに対し、将監没後に跡を継いだ子帯刀(たてわき)は、前野、石崎の横暴を19か条にしたため1637年（寛永14）幕府に訴えた。評定所(ひょうじょうしょ)で何回かにわたる吟味の結果、生駒氏は領地没収され、高俊は出羽(でわ)国（秋田県）矢島1万石に転封された。前野、石崎は切腹、その一党は死罪に処された。これに対し帯刀は松江藩領預(あずけ)となるなど、反対派は軽い処分で事件は落着した。
