Tanagura Domain

 was a "fudai" feudal domain under the Tokugawa shogunate of Edo period Japan. It is located in southern Mutsu Province, Honshū. The domain was centered at Tanagura Castle, located in what is now part of the town of Tanagura in Fukushima Prefecture.
History.
During the Sengoku period, Tanagura was an outpost of the Satake clan, who built the mountain-top Akadake Castle near what would later become Tanagura Castle. After the Satake were defeated and transferred to Dewa Province by Tokugawa Ieyasu, the area was awarded to Tachibana Muneshige. Following the Siege of Osaka, the domain was awarded to Niwa Nagashige, who was ordered to build a completely new castle by Shōgun Tokugawa Hidetada. The Niwa were followed by the Naitō clan, who continued to develop the castle and its surrounding castle town; however, under the Tokugawa shogunate the domain saw frequent changes of "daimyō". 
During the Bakumatsu period, Matsudaira Yasuhide was transferred to Kawagoe Domain, and Abe Masakiyo was transferred from neighbouring Shirakawa Domain. During the Boshin War, the domain was a member of the pro-Tokugawa Ōuetsu Reppan Dōmei, but fell to imperial forces in 1868 after only one day of fighting. In July 1871, with the abolition of the han system, Tanagura Domain briefly became Tanagura Prefecture, and was merged into the newly created Fukushima Prefecture. Under the new Meiji government, Abe Masakoto, the final "daimyō" of Tanagura Domain was given the "kazoku" peerage title of "shishaku" (viscount).
Bakumatsu period holdings.
As with most domains in the han system, Tanagura Domain consisted of several discontinuous territories calculated to provide the assigned "kokudaka", based on periodic cadastral surveys and projected agricultural yields.
