During the 1868 Battle of Toba–Fushimi, the master of Yodo changed his allegiance from the Shogunate to Imperial forces, going as far as closing his gate and refusing protection to the retreating army of the shōgunTokugawa Yoshinobu.
History
In 1623, Matsudaira Sadatsuna entered the domain with 35,000 koku from the Kakegawa Domain in Totomi, and the Yodo domain was established. This was built to replace the Fushimi domain, which was abolished the previous year, to protect Kyoto. Sadatsuna worked hard to build Yodo Castle (this Yodo Castle is said to have been at a different location than Yodo Old Castle, which is known as the former residence of Yodo-dono, the birth mother of Toyotomi Hideyori). Sadatsuna was transferred to the Mino Ogaki domain in March 1633 (Kanei 10).
In his place, Nagai Naomasa from the Shimousa-Koga domain entered with 100,000 koku. Naomasa solidified the foundations of the domain's government by organizing vassals, developing the castle town, and constructing the Kizugawa River to prevent flooding. Naomasa retired on February 28, 1658 and handed over the headship of his family to his son Nagai Naomasa. At this time, Shosei distributed his territory to his younger brothers, so he inherited a territory of 73,600 koku. For example, his sixth son, Naonobu, had knowledge of 3,000 koku and built the Funabashi Jinya. Shosei was then transferred to the Tango-Miyazu domain on February 25, 1669.
In his place, Ishikawa Noriyuki from the Ise-Kameyama Domain came in with 60,000 koku. Noriyuki retired on February 25, 1706, and his successor, Yoshitaka Ishikawa, died on September 2, 1710. His successor, Ishikawa Sokei, was transferred to the Bitchu-Matsuyama Domain on February 15, 1711.
In his place, Matsudaira Mitsuhiro from the Mino Kano domain came in with 60,000 koku. Mitsuhiro died on September 4, 1717, and his successor, Koji Toda, was transferred to the Shima-Toba domain on November 1, 1717.
