== Premodern history ==
[[Japan]] has been inhabited since the Upper Paleolithic period. The first written mention of the archipelago appears in a Chinese chronicle finished in the 2nd century. Between the 4th and 9th centuries, the various tribes of Japan unified under the Yamato emperor, with the Imperial Court based in Kyoto. Beginning in the 12th century, political power was held by a series of military dictators (''shōgun'') and feudal lords (''daimyō''), and enforced by a class of warrior nobility (
==== Azuchi-Momoyama period (1568-1603) ====
Toyotomi Hideyoshi and Oda Nobunaga, two prominent Japanese warlords, sought to reunify and strengthen Japan after the decline of the Ashikaga regime. After Nobunaga’s suicide in 1582, Hideyoshi completed the unification of Japan. He centralized many Japanese institutions, persecuted Christians, and modernized the economy. In the 1590s, Japan invaded Corea but ultimately failed.
In the aftermath of the [https://en.wikipedia.org/wiki/Sengoku_period Warring States era], one of Hideyoshi’s son’s regents, Tokugawa Ieyasu - the only former ally of the Oda clan in Hideyoshi’s inner circle - sought to unify Japan under his rule. After the Battle of Sekigahara, Tokugawa managed to consolidate his rule by 1603.
== Early Edo period (1603-1673) ==
The first seventy years of the Edo period were defined by [https://ja.wikipedia.org/wiki/%E6%AD%A6%E6%96%AD%E6%94%BF%E6%B2%BB martial rule] and the formation of the post-Hideyoshi political order in Japan. The state had extensive interactions with the Dutch, Chinese pirates, pro-Confucianists, and the Japanese Christian movement.
==== Early years and Sakoku ====
Line 15:
From 1633 to 1636, the Japanese state passed the Four Sakoku Ordinances: to ban Japanese migration, construct Desjima, limiting foreign maritime trade, and expulsion of Portuguese traders.
==== [https://en.wikipedia.org/wiki/Shimabara_Rebellion Shimabara Rebellion] (1637) ====
At the time, Japan had an estimated 300,000 Christians. Many of these Christians were peasant farmers and the lower classes, who embraced the faith in opposition to oppressive feudal lords. The Shimabara rebellion, led by the teenage convert Amakusa Shiro, erupted in southern Japan after a raise in taxes. After a few months, it was successfully suppressed with the murder of over 25,000 Catholics and conversions of several more. Many of these Catholics publicly abandoned the faith and became crypto-Christians.
==== Dutch influence in Japan ====
In 1641, the Dutch took over the former Portuguese trading post at Nagasaki. They created [https://en.wikipedia.org/wiki/Dejima Desjima island] in order to conduct trade with the Japanese. Over a period of time, the Japanese became deeply interested in Dutch culture and science, eventually creating the academic school of [https://en.wikipedia.org/wiki/Rangaku Rangaku] (蘭学, lit. Dutch studies).
==== The Keian Affair and the Jōō Massacre ====
In 1651 and 1652, two incidents occurred where rōnin attempted to overthrow the Tokugawa state. The [https://en.wikipedia.org/wiki/Keian_Uprising Keian Affair] largely failed and ended with the suicide of mastermind Yui Shōsetsu. A year later in 1652, Betsuki Shozaemon planned to kill government officials at a memorial service in Edo. A few officials were killed, including [https://en.wikipedia.org/wiki/Abe_Tadaaki Abe Tadaaki] and Kuzo Hiroyuki, before the assailants were put down. Chief advisor [https://en.wikipedia.org/wiki/Sakai_Tadakiyo Sakai Tadakiyo] was injured. It is theorized that security was inadequate in Edo that day due to the arrival of the Fukienese from China.
==== The Hirado Agreement ====
After the 1652 [https://zh.wikipedia.org/wiki/%E6%B1%9F%E4%B8%9C%E6%A1%A5 Battle of Chiangtung Bridge], Koxinga and the Fukien resistance were [[Wahhah Republic#Stabilization%20of%20the%20Qing%20periphery|defeated]] by the Qing. Many refugees fled to the [https://en.wikipedia.org/wiki/Ryukyu_Kingdom Loetsjoes], southeast Asia, and most notably, Japan. Koxinga himself settled in Hirado with permission from the Shogunate, after glorifying his own samurai ancestry through his Japanese mother. He went by the name Tagawa Seikō and became an active member of Japanese society while maintaining his Ming loyalist roots. Koxinga was granted freedom of movement in Kyushu for a month, before it being revoked due to security concerns - he was officially confined to the Hirado lordship thereafter.
The youthful Lord of Hirado, Matsuura Shigenobu, was worried about Hirado’s economy due to Western trade being limited to Desjima. His father, the late Lord Takanobu, was a baptized Catholic and he noticed how the Fukianese community often syncretised Christian, folk, and Buddhist traditions. In the autumn of 1653, the Lord secretly confirmed an agreement with Koxinga and his close ally, the Italian Dominican missionary Vittorio Riccio (who lived in between Amoy, Desjima, and Hirado). The agreement, called the Verboten Collaboratie in Dutch, entailed:
Line 32:
# The Fukianese pirates would staff this endeavor.
# Covertly profiting from Corean trade in the Tsushima Domain, cooperating with collaborationist Dutch traders in Poesjan and Tsjedjoe.
# Covertly profiting from Loetsjoean trade, especially sulfur, in the Satsuma Domain, cooperating with the Fukianese [https://zh.wikipedia.org/wiki/%E9%84%AD%E5%BD%A9 Cheng Cai] who lived in Loetsjoe.
# While disobeying the [https://ja.wikipedia.org/wiki/%E6%85%B6%E5%AE%89%E5%BE%A1%E8%A7%A6%E6%9B%B8 Proclamation of Kei’an], smuggle in luxury goods for peasants such as alcohol.
This agreement was safe until the final months of 1654, when smuggling activities were found out by the Nagasaki secret police. Two Fukienese men, Vittorio Riccio, and seven Japanese men were arrested. Koxinga was not implicated and the Fukienese men were deported to Formosa as servants. The Japanese men received appropriate punishments, while Riccio was imprisoned near Nagasaki.
==== [https://ja.wikipedia.org/wiki/%E6%98%8E%E6%9A%A6 Meireki era] (1655-1658) ====
The Meireki era was defined by the Ōmura Rebellion, the [https://en.wikipedia.org/wiki/Great_fire_of_Meireki Great Fire of Edo], and a key shift in the balance of power in Japanese politics.
===== 8th of October Incident =====
In 1655, the Ōmura Lord [https://ja.wikipedia.org/wiki/%E5%A4%A7%E6%9D%91%E7%B4%94%E9%95%B7 Suminaga] exposed a group of several hidden Christians living on the shores of Ōmura Bay. The Lord, responsible for the imprisoned missionary Vittorio Riccio, had the local Magistrate sentence him to crucifixion for the crime of proselytization and illegal goods smuggling.
The execution of Riccio and 27 Japanese Catholics took place on the 8th of October, when the area was crowded due to the [https://en.wikipedia.org/wiki/Nagasaki_Kunchi Autumn Festival] in nearby Nagasaki. This day was intentionally chosen as a warning to the peasantry. Seconds after the execution, an arquebus fired three shots at the Lord and his family. The Lord’s 29-year-old brother [https://ja.wikipedia.org/wiki/%E7%9A%86%E5%B7%9D%E7%A7%80%E9%9A%86 Hidetaka Minagawa] was killed. Hidekata’s assassin was never found.
After word spread, agitation spread north to Hirado and south to Amakusa within days. Over the next three months, local domains engaged in skirmishes across Kyushu and arrested some 2,000 people. By 1656, it had morphed into a full-scale revolt that centered around the eponymous Ōmura Bay.
===== Ōmura Rebellion (1656-1658) =====
At the outset of the main insurgency, [https://en.wikipedia.org/wiki/Inoue_Masashige Inoue Masashige], Governor of Chikugo, led a sizable Tokugawa force towards the rebellion while intelligence director [https://ja.wikipedia.org/wiki/%E4%B8%AD%E6%A0%B9%E6%AD%A3%E7%9B%9B Masamori Nakane] dispatched agents to the region to quell local insurgencies. Intense battles lasted for a few months before sporadic and guerrilla warfare became more prevalent.
The conflict engulfed almost all of Kyushu, spilling over into Chūgoku, Shikoku, and even a few Corean and Loetsjoe islands. Around 45,000 people were killed or disappeared due to warfare.
Line 63:
===== Meireki Putsch =====
Many details of the Putsch were purged in later records, though commentaries and diary entries on the event do exist. Many samurai, rōnin, and disgruntled scholars conspired to overthrow the current ministerial administration in order to restore peace. It is said that the Lord of Wakayama and brother of the Shogun, [https://ja.wikipedia.org/wiki/%E5%BE%B3%E5%B7%9D%E9%A0%BC%E5%AE%A3 Tokugawa Yorinobu], played an important role in supporting the Putsch.
===== Great Fire of Edo =====
Line 69:
===== Sendai Disturbances =====
Hasekura Tsunenobu, grandson of [https://en.wikipedia.org/wiki/Hasekura_Tsunenaga Hasekura Tsunenaga], began stirring up civil disobedience against the Date clan in Sendai in 1658. The area had historically been the epicenter of Christianity in northern Japan. The Lord of Sendai, [https://en.wikipedia.org/wiki/Date_Tsunamune Date Tsunemune], was infamously a drunkard and unpopular among the aristocracy. His incompetence and indiscriminate persecutions of Christians and peasants allowed for the demonstrations to turn into a mutiny. The overpopulated and outdated bureaucracy of the Sendai domain sparked a series of intra-aristocrat conflicts. Eventually, [https://en.wikipedia.org/wiki/Tamura_Muneyoshi Tamura Muneyoshi] - relative of the Date clan - took control of Sendai in 1660 and maintained a version of the status quo until the ascension of the young lord Date Tsunamura in 1680.
===== Letter from Empress Anne Wang =====
The [[Wahhah Republic#Fate%20of%20the%20House%20of%20Zhu|now-Catholic Zhu family]] of the Ming, surviving in southwestern China, had sent a letter written by [https://en.wikipedia.org/wiki/Empress_Wang_(Southern_Ming) Empress Anne Wang] to the Chinese and Japanese Christians in Kyushu via an empathetic Cantonese trader in 1656 to request rescue before the imminent Qing conquest of Kunming.
In 1662 a contingent of Ming loyalists and Christians reached Kunming via the Loetsjoe kingdom and Macao. At that point, the only survivors were Empress Maria Ma and Crown Prince Constantine Zhu. Empress Anne had died mere weeks before their rescue. They were protected for a few years before eventually returning to mainland China under different names, concealing their identity until the late 18th century.
===== Documentation of events =====
The events of the Meireki era were documented well by [https://en.wikipedia.org/wiki/Hayashi_Razan Hayashi Razan], a Japanese Confucian philosopher. After his death in 1657, his son Hayashi Gaho and the wider Hayashi clan compiled a detailed account and analysis of the era’s events, which were used during the Kanbun Reforms.
==== The [https://en.wikipedia.org/wiki/Kanbun_(era) Kanbun] Reforms ====
After national order was restored in 1660, a series of edicts and policies were enacted during the twelve-year Kanbun era.
===== A cuius regio, eius religio system =====
Each Japanese family, part of a wider ''[https://en.wiktionary.org/wiki/%E9%96%A5#Japanese batsu]'', had to register with a local Buddhist temple since the start of the Tokugawa era - for purposes of administration and social control. In ordinances passed in 1663 and 1668, handpicked loyal domains with a (semi-)Christian aristocracy could allow for families to instead register with local churches. This allowed for churches to be centers of community life, for the public display of faith to become normalized, and for Christian institutions to assimilate into Japanese life under pressure from the local population. A majority of the domains and fiefdoms who chose to give churches such a position were located in Kyushu and the Tōhoku area. In Japanese, it was known as Shusō Hansō (主宗藩宗, lit. ''Lord’s faith, fief’s faith'').
===== Domains’ commercial rights =====
Line 91:
===== Social changes =====
Xenophobia and otherisation largely increased due to the Meireki era. The people of southern Kyushu were often referred to as the [https://en.wikipedia.org/wiki/Hayato_people Hayato], Japan’s own ‘southern barbarians’. Confucian scholars in the service of the Tokugawa state often commented on how uncivilized the Hayato were, and pointed to the Ōmura Rebellion as proof. As a result, numerous Confucian institutes were constructed in cities such as Fukuoka, Nagasaki, and Hinata.
The Tokugawa government also intensified their patronage of the [https://en.wikipedia.org/wiki/Edo_neo-Confucianism Shushi school] of Neo-Confucianism, which they used to justify their centralization and reformist measures. The Hayashi family, devout Confucians, became increasingly influential in Tokugawa society and led the implementation of Confucian practices in everyday life.
== Late Edo period (1673-1754) ==
The last eighty years of the Edo period was defined by the introduction of [https://ja.wikipedia.org/wiki/%E6%96%87%E6%B2%BB%E6%94%BF%E6%B2%BB civil governance], Dutch and Russian incursions into Japanese politics, and the 1754 succession crisis. The two most notable imperial eras of the period were [https://en.wikipedia.org/wiki/Genroku Genroku] and [https://en.wikipedia.org/wiki/Ky%C5%8Dh%C5%8D Kyōho].
==== Takeshima dispute ====
The islands of [https://ja.wikipedia.org/wiki/%E9%AC%B1%E9%99%B5%E5%B3%B6#%E5%90%8D%E7%A7%B0 Takeshima] and [https://ja.wikipedia.org/wiki/%E7%AB%B9%E5%B3%B6#%E6%97%A5%E6%9C%AC%E3%81%A7%E3%81%AE%E5%90%8D%E7%A7%B0 Matsushima], both uninhabited since 1438, became a major focus of Corea-Japan relations in the late 17th century. Japanese from [https://en.wikipedia.org/wiki/Oki_District,_Shimane Oki] entered into a serious dispute with Corean fishermen in the 1690s, when they abducted two Coreans and brought them to Japan to protest their fishing rights. Petrus Hoekstra, a VOC employee in Poesjan, reported the diplomatic dispute to officials in Desjima in 1694 and advocated Dutch intervention.
After several aristocrats and sailors under the Lord of Tottori ignored a Tokugawa ban on fishing near Takeshima, Hoekstra wrote to a Poesjan magistrate, saying that “...the audacious Japanese attitude is an insult to the nation… the Wa-djin must be disciplined…”. When negotiations resumed in 1696 through the [https://en.wikipedia.org/wiki/S%C5%8D_clan Lord of Tsushima], an Dutch ship accompanying the Corean delegation intentionally veered off course, heading towards the Matsushima and Oki isles.
The Dutch ship, manned by Petrus Hoekstra, fired upon Japanese sailors as they headed towards Takeshima ([https://en.wikipedia.org/wiki/Ulleungdo Oelloeng-to]) and threatened to personally report the Tottori estate for disobedience against the Shogun. A Japanese sailor from Oki was captured and brought back to Corea, where he later was coerced to testify to the corruption in the Tottori domain. As a result, the Tottori domain was placed under the authority of the Lord of Tottori’s rival, the [https://ja.wikipedia.org/wiki/%E6%B1%A0%E7%94%B0%E7%B6%B1%E6%94%BF Lord of Okayama], due to the former being incompetent and having no children to succeed him.
==== The Dutch Rush ====
Line 113:
The Dutch established a trading colony, similar in nature to Macao, in the Corean port city of Poesjan in 1710. Explorers employed by Russia saw an opportunity in this and launched an expedition in 1739, establishing a basic commercial relationship. A Japanese studies school was founded in Irkutsk, and was staffed by descendants of Japanese fishermen.
In the economically declining [https://en.wikipedia.org/wiki/Dewa_Province Dewa province], the [https://en.wikipedia.org/wiki/Yonezawa_Domain Yonezawa] and [https://en.wikipedia.org/wiki/Sh%C5%8Dnai_Domain Shōnai] domains, ruled by the Uesugi and Sakai respectively, competed for a head start in Russian trade relations. Both fought over the key port of [https://en.wikipedia.org/wiki/Sakata,_Yamagata#History Sakata]. The Lord of Yonezawa won militarily, but failed to establish relations with the Russians due to infighting and corruption in the Uesugi family. [https://ja.wikipedia.org/wiki/%E6%A3%AE%E5%88%A9%E7%9C%9F#%E5%8F%B0%E9%A0%AD Mori Toshima], a guard employed by the Uesugi, defected to the Sakai family and offered his skills. The Lord of Shōnai’s relatives in Obama offered to lend him the port of Maizuru, which was granted to the Sakai in 1666.
1755 marked the year in which Russian merchants began routinely trading in Maizuru, threatening Dutch monopolies. The Russo-Japanese Trading Company (RYT) formed in 1756. The Lord of Shōnai also owned the trading post of [https://en.wikipedia.org/wiki/Teshio,_Hokkaido Teshio] in northwestern Ezo, which became a port of call for Russian traders.
==== Kyōho Reforms ====
Shogun [https://en.wikipedia.org/wiki/Tokugawa_Yoshimune Tokugawa Yoshimune] introduced a series of separate reforms and policies starting in 1716 in order to restore the financial well-being of the state and consolidate Tokugawa supremacy. Several controls and restrictions were imposed on Japanese society in an effort to increase tsū (sophistication). Yoshimune’s former regent, the Lord of Owari [https://en.wikipedia.org/wiki/Tokugawa_Yoshimichi Tokugawa Yoshimichi], actively criticized the shogunate’s new reforms, creating an intense polarization in the court and undermining the authority of the Shogun.
===== Disastrous taxation reform =====
Increasing revenue in the traditional manner had failed due to the absence of new land surveys and weakening of shogunal authority in the countryside, leading to thousands of koku being unreported to the state. In the government, two factions emerged with differing opinions on raising revenue: one advocating land reclamation with the help of the Dutch, while the other supporting a more income-based tax system (''komononari''). The Shogun eventually decided on an income-based tax system after strong Confucian opposition to utilizing Dutch technological knowledge.
This attempted reform led to extensive peasant revolts, led by village leaders. A policy where if the lords donated an additional 2% of taxes to the state, they would be able to live in their domains for half the year instead of residing in the capital every day. Domain officials had to travel to Osaka or Edo to exchange rice for money in order to pay taxes, creating a financial crisis and a shortage of coins.
Line 132:
==== Hōreki Coup ====
The domains of the cadet branches of the Tokugawa family - the Owari, Kii, and Mito - were valued at 1.6 million koku. The current Shogun was from the Kii family. The Owari and Mito branches, embarrassed and dissatisfied with his rule, collaborated to overthrow him and install [https://ja.wikipedia.org/wiki/%E5%BE%B3%E5%B7%9D%E5%AE%97%E6%98%A5#%E7%B5%8C%E6%AD%B4 Tokugawa Muneharu] of the Owari family as Shogun with [https://en.wikipedia.org/wiki/Mito_Domain#Mito_School Mito Confucianism] as the state ideology.
In 1750, the Mito-Owari coalition successfully deposed Shogun Yoshimune. Yoshimune died shortly after. Shogun Muneharu declared and implemented the articles of his political manifesto, the ''[https://escholarship.org/uc/item/4nn6p372#page=66 Onchi seiyō]''. However, huge budget deficits arose and decimated widespread efforts at reform. Four years later in 1754, Tokugawa Yoshimune was assassinated with no male heir. His death is considered as the end of true Tokugawa rule. Despite his short rule, Muneharu’s ideas and policies were the basis for the establishment of modern Japan.
== Maruoka-Odawara period (1754-1809) ==
Line 140:
==== Meiwa Restoration ====
A series of disturbances plagued Japan after the diminution of shogunal power in the 1750s and 1760s. A riot broke out on Nakasendo highway due to high taxes, amassing 250,000 peasants. Several fires broke out in Edo and Osaka, while hordes of samurai and merchant guilds vied for supremacy. The Lord of Niigita was overthrown and a [https://ja.wikipedia.org/wiki/%E6%96%B0%E6%BD%9F%E6%98%8E%E5%92%8C%E9%A8%92%E5%8B%95#%E8%97%A9%E3%81%A8%E3%81%AE%E5%AF%BE%E7%AB%8B peasant republic] ruled the domain for several months.
Several samurai, lords, & scholars, dissatisfied with the current state of the nation, conspired with the powerful [https://en.wikipedia.org/wiki/Empress_Go-Sakuramachi Empress Go-Sakuramachi] to gradually restore de facto imperial rule on the islands. The movement was supported by the proto-nationalist Mito School of Confucianism, the [https://en.wikipedia.org/wiki/Komagawa_Kaishin-ry%C5%AB#The_Meiwa_incident Komagawa martial arts school], and several merchant and peasant associations.
Several domains de jure recognized and revered imperial rule by 1759, yet de facto operated independently. The imperial court only had true power in the Three Cities (Osaka, Kyoto, and Edo), which had newly appointed civilian administrations enacting policies in accordance with Mito Confucianism and the benevolent ideology of Tokugawa Muneharu. Imperial rule was nominally recognized until 1803, when the Sakai shogunate murdered the sitting Emperor.
==== Satsuma loses the Loetsjoe ====
A [https://zh.wikipedia.org/wiki/%E5%B0%9A%E7%A9%86%E7%8E%8B 1771 tsunami] devastated the [https://en.wikipedia.org/wiki/Ryukyu_Kingdom Loetsjoe kingdom], an island monarchy subject to China and the [https://en.wikipedia.org/wiki/Satsuma_Domain Lord of Satsuma] simultaneously. Several officials in [[Tauland|Dutch Formosa]] privately encouraged interference and annexation of the Loetsjoe kingdom in order to prevent piracy (as many pirates sought refuge in Okinawa), control key shipping lanes, and to control the sulfur trade. From 1772, Dutch ships began to obstruct Loetsjoean shipping lanes. During a Dutch embassy to the capital of [https://en.wikipedia.org/wiki/Shuri,_Okinawa Sjoeri] in 1775, a Dutch official was forcibly installed in [https://en.wikipedia.org/wiki/Yaeyama_Islands Jema County] to ‘assist with reconstruction’ after the tsunami.
The Dutch launched an invasion in 1779, first taking Jema County and the city of Ishigatsjie. By the end of the year, [https://en.wikipedia.org/wiki/I%C5%8Dtorishima King Shō Boku] accepted an EIC protectorate. Many senior officials were ousted from their positions and were replaced by Loetsjoean traitors, Coreans, and Dutchmen. The sulfur-producing island of Torishima was annexed directly by Formosa. In 1783, the native [https://zh.wikipedia.org/wiki/%E7%90%89%E7%90%83%E7%A7%91%E5%BE%8B Criminal Code] was reformed and replaced with a legal system fusing Loetsjoean, Chinese, and Dutch law.
In response, the Satsuma domain launched expeditions against the Formosans over the next few decades, all of which failed to bring Loetsjoe back under their rule. The Satsuma had previously relied on the sugar industry in the Amami islands, trade route profits, and other forms of maritime business. By 1800, their annual revenue was 400,000 koku - a 45% decrease from 1750. As a consequence, the Lords increased revenue by sponsoring Confucian institutes in Kagoshima and establishing tea and sweet potato plantations. A large number of samurai and peasants also illegally emigrated overseas and were employed by the Dutch East India Company.
==== Lake Kusuri Ainu revolt ====
Ainu began fleeing south to Kunashir and the Apasiri area in 1770, when Russia began taking over fishing grounds in the northern Kurils. The sudden influx of Russian traders and the northern Ainu to Ezo created tensions on the island. The [https://en.wikipedia.org/wiki/Matsumae_clan Matsumae clan], responsible for most of Ezo, alerted the officials in Edo of a possible Russian naval invasion. The economic and social strain put on the Ainu culminated in a revolt in 1773, starting in the lakeside village of [https://ja.wikipedia.org/wiki/%E5%BC%9F%E5%AD%90%E5%B1%88%E7%94%BA#%E7%94%BA%E5%90%8D%E3%81%AE%E7%94%B1%E6%9D%A5 Tescaca] and fueled by 3,000 Ainu soldiers. Russian mercenaries were hired by Ainu chieftains, bringing with them European military techniques.
Eventually in 1775, the Tokugawa central administration decided to directly rule Ezo in place of indirect rule via the Matsumae clan. Thousands of Japanese soldiers contained the rebellion and the Russian mercenaries to the rural north of Ezo, massacring or expelling Ainu populations in the south. As the Matsumae lost their power, they started to look for allies elsewhere. They became friendly towards the Russians and their various Japanese allies - such as the rising Sakai clan.
==== Kansei Reunification ====
Sakai Tadamichi, Lord of [https://en.wikipedia.org/wiki/Obama_Domain Obama] and prominent member of the [https://en.wikipedia.org/wiki/Sakai_clan Sakai clan], rose to prominence as the [https://en.wikipedia.org/wiki/Tair%C5%8D Tairō] in the imperial court in 1779. After the disaster that followed the [https://en.wikipedia.org/wiki/Great_Tenmei_famine Tenmei famine], several clans allied with the Sakai in order to reunify Japan. The [https://en.wikipedia.org/wiki/Matsumae_clan Matsumae], [https://en.wikipedia.org/wiki/Mito_Domain Mito], [https://en.wikipedia.org/wiki/Sendai_Domain Date], [https://en.wikipedia.org/wiki/Sayama_Domain Sayama], [https://en.wikipedia.org/wiki/Satsuma_Domain Shimazu] and [https://en.wikipedia.org/wiki/Hirado_Domain Matsuura] - were the earliest to form an alliance with the Sakai by 1785, and would eventually become the new state’s ''[https://en.wikipedia.org/wiki/Fudai_daimy%C5%8D fudai]''. Notably, Russian merchants and most Japanese Christian lords supported this coalition.
The Dutch, on the other hand, opposed the reunification of Japan and took measures to provide for their allies in Japan, such as the [https://en.wikipedia.org/wiki/Uesugi_clan Uyesugi], [https://en.wikipedia.org/wiki/Matsudaira_clan Matsudaira], most crucially the uber-wealthy [https://en.wikipedia.org/wiki/Hosokawa_clan Hosokawa clan]. Hosokawa Toshitsune, of the Kumamoto lordship, became the archrival of Sakai Tadamichi and claimed the position of Shogun for himself, based on the Hosokawa’s direct descent from [https://en.wikipedia.org/wiki/Seiwa_Genji Emperor Seiwa].
In 1795, the Netherlands was invaded by [[France]] in the [[History of Europe#French%20Revolution%20and%20the%20Augustine%20Wars%20(1780s-1814)|Augustine Wars]] and subsequently lost their ability to project power in eastern Asia. Subsequently, the Sakai coalition hired Russian mercenaries, Yellow Sea pirates, and hordes of discontented rōnin to push for the unification of Japan under their rule. Several notable battles include the [https://en.wikipedia.org/wiki/Takashima,_Shiga Battle of Takashima], the Second [https://en.wikipedia.org/wiki/Nara_(city) Siege of Nara], the [https://en.wikipedia.org/wiki/Arakawa_River_(Uetsu) Battle of Arakawa River], and the collective [https://en.wikipedia.org/wiki/Hizen_Province Battles of Hishu].
Eventually in 1808, the Sakai had established their influence over most of Japan. However, the Tokugawa clan still maintained power in [https://en.wikipedia.org/wiki/Oshima_Province Oshima] after expelling the Matsumae clan from their historic territories. Northern Ezo was ruled by Ainu chiefs with small enclaves ruled by Japanese lords. Several fiefs in central and western Japan also held out, protecting their own territories as well as Desjima.
By 1809, the Sakai were able to establish order in the cities of Edo, Osaka, and Kyoto. The Emperor had also recognized Sakai Tadamichi as the new Shogun. The Tairō, rebranded in Western records as the ‘Prime Minister of Japan’, was occupied by the Shogun’s cousin, Sakai Chikatsu.
== Kumohama period (1809-1895) ==
The era’s name (meaning ‘cloud beach’) was taken from the coastal [https://en.wikipedia.org/wiki/Obama_Castle_(Wakasa_Province) Unpin Castle], which belonged to the Lord of Obama of the Sakai clan.
==== Terms of unification ====
==== Russian betrayal & Ainu separatism ====
The [https://ja.wikipedia.org/wiki/%E5%B0%8F%E7%94%B0%E5%8E%9F%E8%97%A9#%E5%A4%A7%E4%B9%85%E4%BF%9D%E5%AE%B6_2 Odawara domain] was still in a state of rebellion in 1809, being ruled by the Matsudaira-loyalist Okubo clan. A Russian flotilla under Admiral Gunin Ermilov approached the [https://en.wikipedia.org/wiki/Izu_Province Idzu peninsula] in order to expel the Okubo from the province. Russia had established a small post in Itō in 1744 exclusively for shipbuilding purposes. After the Okuba samurai were expelled from Idzu, Admiral Ermilov did not leave the peninsula when the Shogun ordered him to. The Sakai clan were in debt to Russian merchants and had refused to pay them back instantaneously.
A few months later, the Imperial Russian Navy seized the ports of Maizuru and Teshio as well, which they had been trading at since 1755.
