Akashi Domain

A domain located in Akashi County, Harima Province (Hyogo Prefecture). During the Tenbun period (1532-1555), the local lord Akashi Nagayuki's Edakichi Castle was known on the plateau west of the Akashi River, and during the Tensho period (1573-1592), Bessho Yoshichika built Funage Castle on the plains below Shimotsuke. Both were called Akashi Castle. Around the time of Hashiba (Toyotomi) Hideyoshi's (Hashiba Toyotomi) capture of Miki Castle (Bessho Nagaharu) while advancing to subjugate Harima, Hachisuka Masakatsu, who was on Hideyoshi's side, temporarily lived in Funage Castle in 1576 (Tensho 4), and Takayama Ukon in 1578. After the Battle of Sekigahara in 1600 (Keicho 5), Ikeda Terumasa ruled over the entire Harima Province with 520,000 koku of rice. In the same year, Kuroda Nagaoki became the lord of Funakami Castle, but then moved to Akizuki in Chikuzen, where Yukisuke's surviving son, Yoriyuki, took over as a subsidiary castle for Terumasa.

The Ikeda clan of Himeji in Harima Province was transferred to Tottori in 1617 (Genwa 3) during the reign of Mitsumasa, and Honda Tadamasa ruled over the area west of Kako and Innami. On the other hand, Tokugawa Ieyasu's grandson Ogasawara Tadazane was appointed to the Akashi and Miki counties with a fief of 100,000 koku from Matsumoto in Shinano Province, and initially lived in Funakami Castle. The following year, in 1618, he was ordered to build Akashi Castle on Hitomaruyama. After that, Toda Yasunao was appointed to the fief in 1633 (Kan'ei 10), Okubo Tadamoto in 1639, and Matsudaira Tadakuni in 1649 (Keian 2). All three families had a fief of 70,000 koku, but Tadakuni's heir, Shishi Nobuyuki, divided 5,000 koku among his younger brothers. After that, Honda Masatoshi, who came to power in 1679 (Enpo 7), had a fief of 60,000 koku. Masatoshi tried to develop new fields on the Yamate Plateau, but was found to be unkind by the inspectors, and in 1682 (Tenwa 2) he was transferred to Iwase County in Oshu with a new fief of 10,000 koku. In his place, Matsudaira Naoaki, a branch of the Echizen family, came from Echizen Ono and settled there. In 1839 (Tenpo 10), he was given an additional 20,000 koku, giving him a total of 80,000 koku, and his fief extended to the three counties of Akashi, Miki, and Sayo, until the abolition of the feudal domains and establishment of prefectures in the Meiji period (1871).

播磨(はりま)国（兵庫県）明石郡に置かれた藩。天文(てんぶん)期（1532～1555）には明石川西の台地に国人(こくじん)明石長行(ながゆき)の枝吉城が知られ、天正(てんしょう)期（1573～1592）に別所吉親(べっしょよしちか)が下手の平地に舟上(ふなげ)城を築いた。ともに明石城といわれた。この舟上城は、播磨平定に陣を進める羽柴(はしば)（豊臣(とよとみ)）秀吉の三木(みき)城（別所長治(ながはる)）攻略に前後して、1576年（天正4）秀吉方の蜂須賀正勝(はちすかまさかつ)、1578年高山右近(うこん)が一時居城とした。1600年（慶長5）関ヶ原の戦い後、池田輝政(てるまさ)が播磨一国52万石を領知した。同年黒田長興(ながおき)が舟上城主になったが、改めて筑前(ちくぜん)秋月に転じ、ここには輝政の支城として、兄之助(ゆきすけ)の遺子由之(よりゆき)が入った。

　播磨国姫路の池田氏が1617年（元和3）光政(みつまさ)の代に鳥取に転封し、本多忠政(ただまさ)が加古(かこ)、印南(いなみ)以西を領知した。他方、明石、三木両郡10万石には徳川家康の外孫小笠原忠真(おがさわらただざね)が信濃(しなの)国松本から入封して、初め舟上城におり、翌1618年命ぜられて人丸(ひとまる)山に明石城を築いた。以後は1633年（寛永10）戸田康直(やすなお)、1639年大久保忠職(ただもと)、1649年（慶安2）松平忠国(ただくに)が入封。3家とも領知7万石で、ただ忠国の嗣子(しし)信之(のぶゆき)が弟に5000石を分知した。その後1679年（延宝7）に入った本多政利(まさとし)から本高6万石になる。政利は山手台地の新田開発に努めたが、巡見使に不仁を指摘され、1682年（天和2）奥州岩瀬郡に新知1万石で遷(うつ)された。かわって越前(えちぜん)家支流の松平直明(なおあき)が越前大野より入って定着した。1839年（天保10）2万石加増で計8万石、領知は明石、三木、佐用(さよ)3郡にわたり、明治の廃藩置県（1871）に及んだ。
