The Ōuetsu Reppan Dōmei (奥羽越列藩同盟?) "Alliance of the domains of Mutsu (陸奥), Dewa (出羽) and Echigo (越後)", Northern Alliance (北部同盟 Hokubu Doumei?) or Oh-U-Etsu (奥羽越, Oh-shu (奥州), U-shu (羽州) and Etsu-shu (越州)) Confederation of Allied Domains (列藩同盟) was a Japanese military-political coalition established and disestablished over the course of several months in early to mid-1868 during the Boshin War (戊辰戦争). Its flag was either a white interwoven five-pointed star on a black field, or a black interwoven five-pointed star on a white field.
Sometimes referred to as the "Northern Alliance" (北部同盟) or "Reppan Domei" (列藩同盟), it centered around the Sendai (仙台藩), Yonezawa (米沢藩), and Nihonmatsu (二本松藩) domains, and drew together nearly all domains from the provinces of Mutsu (陸奥国) and Dewa (出羽国), several domains of northern Echigo Province (越後国), and even the Matsumae domain (松前藩) of Ezo (蝦夷地) (modern-day Hokkaidō (北海道)). Headquartered at Shiroishi Castle (白石城), the alliance's nominal head was Prince Kitashirakawa Yoshihisa (北白川宮能久親王), the onetime abbot of Kan'eiji Temple (寛永寺) in Edo (江戸) who fled north following the Satsuma-Chōshū (薩長) takeover of the city, who declared himself "Emperor Tobu" (東武皇帝), with Date Yoshikuni (伊達慶邦) of Sendai and Uesugi Narinori (上杉斉憲) of Yonezawa as the head of the Alliance. Although heteroclitic in nature, the Alliance formed of a combination of modern and traditional forces, and mobilized a total of about 50,000 soldiers. Though the alliance did its best to support the Aizu domain (会津藩), Aizu was not formally part of the alliance "Kaisho Alliance" (会庄同盟); neither was Shōnai (庄内藩).
While the alliance was a bold, innovative step that combined the military forces of several dozen domains, it was unable to fully act as a single, cohesive unit, and with the fall of Sendai and Aizu, it effectively collapsed.
