Sōma clan
During the Boshin War of 1868–69, the Sōma clan initially attempted to remain neutral as under Sōma Toshitane the domain was relatively small and had negligible military forces. However, following the defeat of the Tokugawa forces at the Battle of Toba–Fushimi in February 1868, he was pressured by his more powerful neighbors (including Iwakitaira Domain and Sendai Domain) into joining the Ōuetsu Reppan Dōmei. The Satchō Alliance forces advanced through the Hamadōri region and captured Nakamura Castle with only token resistance a few months later. His predecessor, Sōma Michitane, formally surrendered to the Meiji government; however, the domain was not punished, and Toshitane was restored as domain governor by the new government until the abolition of the han system in 1871.
