Republic of Ezo

History

On January 27, 1869, the independent "Republic of Ezo" was proclaimed, with its government structure based on the United States. Suffrage was limited to the samurai class. Votes were cast through open ballots and resulted in the election of Enomoto Takeaki as sosai, an office variously translated as president or director-general, and Matsudaira Tarō as fuku-sosai (vice-president or assistant governor-general). Some cabinet members were elected by the troops as well; Arai Ikunosuke was chosen as kaigun-bugyō (Navy minister) and Ōtori Keisuke as rikugun-bugyō (Army minister). This was the first election ever held in Japan, where a feudal structure under an Emperor with military warlords was the norm. Through Hakodate magistrate Nagai Naoyuki, attempts were made to reach out to foreign legations present in Hakodate to obtain international diplomatic recognition. Notably, due to the United States' involvement through Commodore Matthew Perry's expedition to forcefully end Japan's 220-year-old policy of isolation and open ports to American trade, the Western world had limited interest in supporting a breakaway state over the new Meiji government, which offered more stability and potential cooperation.

On the same day, a celebration of the Ezo territory all-island settlement (Ezo territory declaration ceremony) was held, proclaiming the establishment of a provisional government with Enomoto as president.

The treasury included 180,000 gold ryō coins Enomoto retrieved from Osaka Castle following shōgun Tokugawa Yoshinobu's precipitous departure after the Battle of Toba–Fushimi in early 1868.

During the winter of 1868–1869, the defences around the southern peninsula of Hakodate were enhanced, with the star fortress of Goryōkaku at the centre. The land force was organised under a joint Franco-Japanese command, commander-in-chief Ōtori Keisuke being seconded by the French captain Jules Brunet. The troops were divided into four brigades, each commanded by a French officer (Arthur Fortant, Jean Marlin, André Cazeneuve and François Bouffier). Each brigade was in turn divided into two battalions, and these into four companies.

Brunet demanded (and received) a signed personal pledge of loyalty from all officers and insisted they assimilate French ideas. An anonymous French officer wrote that Brunet had taken charge of everything:

... customs, municipality, fortifications, army; everything passed through his hands. The simple Japanese are puppets whom he manipulates with great skill... he has carried out a veritable 1789 French Revolution in this brave new Japan; the election of leaders and the determination of rank by merit and not birth—these are fabulous things for this country, and he has been able to do things very well, considering the seriousness of the situation...

Defeat by Imperial forces and aftermath

Imperial troops soon consolidated their hold on mainland Japan, and in April 1869 dispatched a fleet and an infantry force of 7,000 men to Hokkaido. The Imperial forces progressed swiftly, won the Battle of Hakodate, and surrounded the fortress at Goryōkaku. Enomoto surrendered on June 26, 1869, turning the Goryōkaku over to Satsuma staff officer Kuroda Kiyotaka on June 27, 1869. Kuroda is said to have been deeply impressed by Enomoto's dedication in combat and is remembered as the one who spared the latter's life from execution. On September 20 of the same year, the island was given its present name, Hokkaido (Hokkaidō, literally "Northern Sea Region").

Enomoto was sentenced to a brief prison sentence, but was freed in 1872 and accepted a post as a government official in the newly renamed Hokkaido Land Agency. He later became ambassador to Russia and held several ministerial positions in the Meiji Government

The rebels' French allies, some of them wounded, sailed from Hakodate on 9 June aboard the French vessel Coëtlogon to Yokohama, where Cazeneuve was admitted to the local naval hospital. Their leader Jules Brunet returned to France in September 1869. He was suspended from active duty in the French army in October, and was later put on trial but received only a light sentence of minor loss in seniority. In February 1870 Brunet was recalled to service, and back as a captain fought in the Franco-Prussian War later that year. In 1871, Arthur Fortant, Jean Marlin, and François Bouffier signed an employment contract with professor Harada Ichido (father of Harada Naojirō) and returned to Japan as civilians to teach at the military school of Osaka.

Perspectives

While later history texts were to refer to May 1869 as being when Enomoto accepted Emperor Meiji's rule, the Imperial rule was never in question for the Ezo Republic, as made evident by part of Enomoto's message to the Daijō-kan (太政官, Dajōkan) at the time of his arrival in Hakodate:

The farmers and merchants are unmolested, and live without fear, going their own way, and sympathising with us; so that already we have been able to bring some land into cultivation. We pray that this portion of the Empire may be conferred upon our late lord, Tokugawa Kamenosuke; and in that case, we shall repay your beneficence by our faithful guardianship of the northern gate.

Thus from Enomoto's perspective, the efforts to establish a government in Hokkaido were not only for the sake of providing for the Tokugawa clan on the one hand (burdened as it was with an enormous amount of redundant retainers and employees) but also as developing Ezo for the sake of defence for the rest of Japan, something which had been a topic of concern for some time. Recent scholarship has noted that for centuries, Ezo was not considered a part of Japan the same way that the other "main" islands of modern Japan were, so the creation of the Ezo Republic, in a contemporary mindset, was not an act of secession, but rather of "bringing" the sociopolitical entity of "Japan" formally to the island of Hokkaido.
