Matsuyama Castle
was founded in 1647 for Sakai Tadatsune, the third son of Sakai Tadakatsu, who was assigned 20,000 "koku" of new rice lands in Akumi District. The third "daimyō", Sakai Tadayoshi served as "wakadoshiyori", and was awarded an additional 5000 "koku" in Kōzuke Province. He also built the Dewa-Matsuyama Castle, from which his successors continued to rule until the Meiji Restoration. During the Boshin War, the domain sided with the Ōuetsu Reppan Dōmei, for which it was punished by the Meiji government with the loss of 2500 "koku". It was renamed in 1869, and was abolished with all the other domains in 1871. The final "daimyō", Sakai Tadamasa subsequently received the "kazoku" peerage title of "shishaku" (viscount).
