  • Lords of the East, Part 1

    Lords of the East, Part 1

    This post is coming out on Christmas Day, so Merry Christmas (if that’s your thing).

    We’ve taken a look at the Hojo before, their origins, and their founder, Hojo Soun, featured in a post I wrote a while back, which can be found here:

    The mon of the Hojo Clan.

    Soun – Rise of the Hojo

    In brief, the Hojo, as they became known, were originally called the Ise, and their founder, Soun, invaded Izu Province in 1493 before conquering Odawara in neighbouring Sagami Province in 1495. It was Soun’s son, Ujitsuna, who adopted the name and mon of the Hojo Clan, who had been the de facto rulers of Japan during the late Kamakura Shogunate.

    Exactly why he chose to change the clan’s identity is a matter of some debate, with the most obvious reason being the prestige the name brought, which would help to convince the clans that were ‘native’ to the area that the Ise (now the Hojo), who had originated elsewhere, belonged.

    The Hojo based themselves permanently at Odawara from around 1516, and it is from there that Ujitsuna, the second lord (or first, if you’re feeling pedantic about names), would rule. After Soun passed the rule to him in 1518, Ujitsuna set about quite literally making his mark on Sagami Province. He was something of a prolific builder and established or rebuilt several famous shrines that still stand today.

    After 1521, Ujitsuna also began to call himself the shugo (governor) of Sagami Province. Officially, he was never bestowed with this title by the Shogun, but by this point, it hardly mattered; no one in Kyoto was in a position to stop him, and Ujitsuna ruled as governor, in fact if not technically by law.

    It’s also around this time that the Ise Clan became the Hojo Clan. Traditionally, this was seen as just an arbitrary name change, seeking to attach the somewhat lowborn Ise to an illustrious name. More recent evidence suggests that it might not have been so cynical a move, with some sources suggesting that Ujitsuna’s wife, Yojuin, was a descendant of the Yokoi Clan, who were in turn descendants of the original Hojo.

    This would still be a pretty tenuous link on its own. Still, shortly after the name change, the Imperial Court rewarded the Hojo with the title of “Saikyo no Daibu“, the same title the original Hojo were bestowed with. We’ve discussed previously how, by this point, Imperial titles were worthless on their own but still carried considerable prestige. This title put the Hojo on the same rank (in the eyes of the court, anyway) as the nearby Imagawa, Takeda, and Uesugi Clans, families with undisputed lineage.

    Hojo Ujitsuna. It was his decision to rename his clan that led to the adoption of their famous name.

    All this suggests that the claim to the Hojo name might not have been all that spurious, but acceptance by the Imperial Court did not translate to being a member of the ‘club’, and certainly, in the case of the Uesugi (the Ogigayatsu Branch, at least), the Hojo were little more than upstarts.

    The Sengoku Period was a time when lineage no longer held the same meaning it once did. A clan with an impressive family tree could (and often did) find itself crushed by clans that, by comparison, had no real ancestry and might have once been subordinates. This phenomenon, called Gekokujo in Japanese (which means low overthrows high), was common across the realm in this period, and a clan like the newly dubbed Hojo would set about establishing its rule at the point of a sword.

    Ujitsuna was very much a man of his time, and by the mid 1520s, he had subdued all of Sagami Province (modern Kanagawa) and advanced into southern Musashi, the neighbouring province, close to the area of modern Tokyo. Faced with further advances by the Hojo and defection of lords in Western Musashi, the Ogigayatsu were forced to respond.

    In February 1524, a Hojo force of some 10,000 clashed with the Ogigayatsu at the Battle of Takanawahara. The battle was a decisive victory for the Hojo, with the Ogigayatsu forces retreating to Edo Castle (on the site of the modern Imperial Palace), only for it to fall shortly afterwards, forcing the Ogigayatsu to withdraw further north to another stronghold at Kawagoe.

    Ujitsuna, flush with victory, ordered a rapid advance and made rapid progress before a counterattack led by Ogigayatsu ally, Takeda Shingen (remember him?), defeated the Hojo at Iwatsuki in mid 1524, obliging Ujitsuna to seek peace. He would break the peace in early 1525, and despite some early success, the Ogigayatsu, allied with the Takeda, and united with their cousins on the Yamauchi Uesugi, proved to be too much for the Hojo. In September 1525, the Hojo were defeated at the Battle of Shirakobara. Although Edo Castle would hold out, by mid-1526 the Hojo had been driven out of Musashi Province altogether, with Tamanawa Castle on the border of Sagami Province coming under attack in November that year.

    The Hojo had their back to the wall, but the forces arrayed against them were a mishmash of different clans, with different goals. A lack of coordination meant that when the time came to attack Sagami in force, the attack was beaten back, with troops of the Satomi (allies of the Ogigayatsu) making it as far as Kamakura before being defeated. During their retreat, they burned the famous Tsurugaoka Hachimangu Shrine. This carried significant political consequences, and Ujitsuna was able to convince the Imperial Court and the Shogunate to censure his enemies.

    This official reprimand created enormous political pressure, and by the end of 1527, Ujitsuna had been able to make peace. Though it is difficult to predict what the outcome might have been otherwise, it is important to remember that Hojo territory faced enemies in three directions, and it is not improbable that, had peace not been agreed, then they may have been overwhelmed.

    This reprieve was not wasted by Ujitsuna, either. In 1530, when Takeda forces once again marched against Sagami, the Hojo dispatched a force to meet them. Though the Hojo would prove victorious in this campaign, the Ogigayatsu sought to take advantage of Ujitsuna’s distraction and sent an army of their own, hoping to trap the Hojo army between them and the Takeda.

    Standing in their way was Ozawa Castle, controlled by Ujitsuna’s son and heir, Ujiyasu. Sources say that the Hojo were outnumbered as much as 5 to 1, but on the night of July 6th, 1530, Ujiyasu launched a surprise attack on their camp, winning a decisive victory and returning momentum in the war to the Hojo.

    With this momentum, the Hojo were able to take advantage of the same division that had plagued their enemies a few years earlier. Ujitsuna identified the Satomi Clan (from modern Chiba) as a weak link and focused his attention on them, bribing several family members who were unhappy with the current leadership and seeking to incite a rebellion that the Hojo could exploit.

    The plot was discovered, however, and so the Hojo instead relied on good, old-fashioned, brute force, dispatching an army across what is now Tokyo Bay to Awa Province on the southern tip of the Boso Peninsula. Despite the plot’s failure and the execution of several conspirators, some members of the Satomi still rose up in support of the Hojo invasion. What followed was a series of victories as the Hojo-Satomi alliance took castle after castle, culminating in the Battle of Inukake in 1534, which saw the Hojo-Satomi defeat their rivals and replace the head of the Satomi Clan with a Hojo ally.

    Whilst the Hojo were victorious on their eastern flank, the western flank was secured by a long-term alliance with the Imagawa. You may remember that Hojo Soun had actually started out as a vassal of the Imagawa, and though the Hojo had since risen to a position of equality with their former masters, the relationship remained close.

    With the bulk of his forces busy against the Satomi, Ujitsuna requested his Imagawa ally, Ujiteru, invade Takeda territory to ensure they wouldn’t intervene. The Imagawa obliged and invaded Kai Province in July 1534; they were initially successful but soon became overextended and had to retreat to their home in Suruga. A Takeda counterattack was considered so dangerous that Ujitsuna withdrew forces from the West to face it. The Takeda, remembering their defeat at the hands of the Hojo a few years earlier, tried to lure Ujitsuna into an ambush in the narrow mountain passes of Kai, seeking revenge.

    Ujitsuna was apparently aware of the strategy, however, and dispatched a force to outflank the Takeda, turning the ambushers into the ambushed at the Battle of Yamanaka on September 19th, 1535. The defeat was so severe for the Takeda that the road into Kai province now lay open, and Ujitsuna apparently intended to crush the Takeda once and for all and take the whole of Kai Province for himself.

    This invasion was eventually called off as the Ogigayatsu proved to be a more pressing concern, and over the next few years, the geopolitical situation would shift considerably. In 1536, Imagawa Ujiteru died suddenly, aged just 21 or 22. He left no heirs, and so the clan quickly descended into civil war. At about the same time, famine and an epidemic broke out in Kai Province, severely weakening the Takeda.

    The Imagawa civil war was won by Yoshitomo, Ujiteru’s younger brother, but the devastation in Suruga left the clan severely weakened, and they sought peace with the Takeda, who, suffering their own calamities, quickly agreed, with Yoshitomo marrying Takeda Shingen’s daughter to establish a new alliance. Ujitsuna recognised that his alliance presented an intolerable risk to his western frontier and resolved to do something about it.

    In early 1537, Ujitsuna led 10,000 men into Suruga Province, winning a series of crushing victories over the Imagawa and decisively bringing an end to decades of close relations. Fearing overextension, however, Ujitsuna limited his conquests to the territory east of the Fuji River, and a truce was declared shortly afterwards, which was convenient, as the death of the Ogigayatsu lord left the clan in disarray and presented a golden opportunity for further Hojo expansion, but we’ll talk about that next time.

  • Soun – Rise of the Hojo

    Soun – Rise of the Hojo

    The mon of the Hojo, and Later Hojo clans.

    Late 15th-century Japan was a chaotic place, but as we all know by now, chaos also presents opportunity. As central authority declined, local clans would move to fill the void. Some of these clans would fall almost as quickly as they had risen, others would continue to survive in one form or another throughout the Sengoku Period, and a select few would go on to be truly great.

    The focus of this post is one of them, the Hojo (hence the title). Right away, I want to be clear that this Hojo and the Hojo we looked at previously (the ones who were regents during the Mongol Invasions) were not related, despite the same name and mon. Sometimes, this second Hojo Clan is called the “Later” Hojo (Go-Hojo) in Japanese, but for our purposes, we’ll just call them the Hojo and hope you remember the distinction.

    Adding to our confusion, the founder of the clan, Hojo Soun, wasn’t actually called that. He was a member of the Ise Clan, and it was his son, the second “Lord” Hojo, who adopted the name and mon. Again, while it is technically more accurate to refer to this founder as Ise Souzui, we’ll call him Hojo Soun, because a) that’s the name he’s best remembered by, and b) it’ll get confusing if we keep changing his name.

    Hojo Soun, who wasn’t called Hojo Soun, during his lifetime.

    Side Note: Name changes were common in Japanese culture, with someone’s birth name rarely being the name they are recorded by historically. When you factor in nicknames, titles, honorifics, etc, you have individuals who may have gone by any number of names. Up until now (and continuing after this), I have always called historical characters by their most commonly used name, just in case you were wondering.

    The man who would become Hojo Soun is the subject of considerable mythologising. In the pre-modern period, it was widely assumed that he had been a poor samurai who had risen to a position of power by sheer force of will, pulling himself up by the proverbial bootstraps.

    20th-century scholarship has shed more light on his origins, however. He was a member of the Ise Clan, as we mentioned previously, and was born either in Kyoto or Ibara, in modern Okayama Prefecture. His family were not at the highest ranks, but they were administrators for the Shogun, meaning that they were often close to the centre of power and were certainly not the impoverished provincial family of later myth and legend.

    Soun’s exact origins are still a little unclear (we’re not even 100% sure what year he was born, though 1456 is considered most likely), but his rise to power came during the chaotic violence of the Onin War. As we looked at previously, one of the ancillary conflicts was in the Kanto, where Ashikaga Shigeuji and the Uesugi Clan clashed violently. Officially, Shigeuji was a rebel against the Shogunate, and the Uesugi were loyal servants, although in reality, neither side paid much attention to the capital.

    One of the other clans in the Kanto at this time was the Imagawa, who remained loyal to the interests of the Shogun. In 1476, the head of the Imagawa was killed in battle, and his heir was just a boy (Ujichika). Factions quickly formed within the clan seeking to assert rival claims to leadership.

    With the clan fracturing and external rivals seeking to take advantage, Soun, who was the brother of Lady Kitagawa, Ujichika’s mother, is said to have arrived at the Imagawa home in Suruga Province (in modern Shizuoka) to negotiate a peaceful settlement at the request of his sister. An agreement was reached in which the cousin of the previous leader (Norimitsu) would stand in as acting leader until the young boy came of age, whilst the rival factions were convinced (or compelled) to withdraw.

    It is debated exactly what role Soun played in this negotiation. It is noted that he was very young (perhaps 20 or 21) to be a negotiator, and his name doesn’t appear in any official government records. The withdrawal of rival forces is also suggested to have been a reaction to problems elsewhere (the Uesugi faced rebellion at home, for example) and not a result of Soun’s negotiating prowess. While peace was certainly achieved within the Imagawa Clan, it is entirely possible that Soun’s role in achieving it was minimal, or perhaps even a later fabrication.

    The first ‘official’ records of Soun come from the period of 1481-87, when he is recorded as a subordinate to the Shogun, presumably taking some role in the administrative affairs of the government. It is also speculated that Soun’s later departure for Suruga Province was motivated by legal troubles surrounding unpaid debts. Again, the exact nature of this problem isn’t clear, but there was certainly a legal case involving Soun and one of his creditors dated to this period, although the outcome is apparently lost.

    In 1487, the previous agreement that had led to peace within the Imagawa Clan broke down. Norimitsu, who had been chosen to stand as ‘regent’ during the minority of Imagawa Ujichika, refused to step down. Although Soun’s role in the initial negotiation is debated, he certainly returned to Suruga Province around this time to force a settlement, apparently with the approval (or possibly at the direct order) of the Shogun and at the request, once again, of his sister, Lady Kitagawa.

    Norimitsu had once been able to call on the support of external clans, but the political situation in the Kanto had changed in the decade since the original settlement, and that support no longer existed. Soun based himself at Ishiwaki Castle (in modern Yaizu, Shizuoka) and gathered supporters of Ujichika to his banner.

    In late 1487, Soun led an attack on Norimitsu and his supporters, defeating them in a short, sharp campaign that ended with Norimitsu’s suicide and Ujichika’s confirmation as leader of the Imagawa Clan. Soun was rewarded for his actions, but the exact location of his new lands is disputed, with several possible locations including the aforementioned Ishiwaki Castle.

    Though the exact location of his base isn’t known for sure, Soun certainly remained in Suruga Province in the immediate aftermath of his success, acting as a protector for the young Ujichika. It is also suggested that during this period he acquired or was rewarded with estates in Izu Province, though again, that isn’t recorded with certainty.

    Soun’s actions following this are murky; he appears to have returned to the direct service of the Shogun in around 1491, though he seems to have remained physically in Suruga Province. In 1493, the Meio Coup changed Soun’s situation considerably, although again the exact circumstances are open to speculation.

    What is certain is that Soun would lead an attack into neighbouring Izu Province that would eventually see him take control of the entire province. Some sources suggest that Soun was acting on the orders of Hosokawa Masatomo, the instigator of the Meio Coup; others indicate that Soun was acting on his own initiative. The situation in the Kanto was already volatile, and the coup in Kyoto had only made things worse, giving Soun a chance to improve his fortunes.

    Soun’s actual conquest of Izu is subject to considerable mythologising, with some stories telling us that he spied on the province in person, posing as a pilgrim to the area’s many hot springs, whilst others say that he was welcomed as a liberator and kept his army under tight control, preventing any pillaging. Soun is also supposed to have secured the province in under 30 days, launching a surprise attack on the residence of the previous lord of Izu, and either killing him or forcing him to commit suicide.

    The reality seems to have been a protracted campaign, with Soun trying to capture the leader of the province in a rapid advance, but failing to do so, leading to a drawn-out war that would not be finally resolved until 1498, though the historical record does seem to suggest that Soun’s victory was more or less guaranteed after around 1495.

    Despite his conquest of Izu, Soun remained a nominal vassal of the Imagawa Clan and took an active part in their campaigns in the Kanto. He would campaign on their behalf in Kai Province, and in Sagami (modern-day Yamanashi and Kanagawa Prefectures), famously capturing Odawara Castle in late 1495. The legends tell us that Soun captured the mighty fortress through trickery, convincing the lord to go hunting and then taking the castle while he was away. Modern scholars suggest that a large earthquake that year undermined the fortifications of Odawara and made holding it untenable.

    In the short term, Soun would continue to support the Imagawa Clan, but as time went on, he began to take on an increasingly independent appearance, as his power grew, and the Imagawa found themselves distracted by events elsewhere. In 1507, the Eisho Disturbance (which led to the Hosokawa Rebellion we talked about previously) ended what little remained of Shogunate influence in the Kanto, and with the Imagawa distracted (or by some accounts, overstretched), Soun was able to extend his direct control of Sagami and Izu Provinces.

    Soun would clash with the Miura Clan of Sagami, who were in turn supported by the Ogigayatsu branch of the Uesugi Clan. Soun would advance on Edo Castle (on the site of the modern Imperial Palace in Tokyo) in early 1510, but a counterattack by the Miura and Ogigayatsu would drive him back as far as his base at Odawara.

    Soun would survive this crisis, and the destruction of the Miura Clan is said to have become the singular focus of his later life. Starting in the summer of 1512, Soun would make steady advances against the Miura, driving them out of Sagami Province, and defeating supporting attacks from the Ogigayatsu, until, by July 1516, the Miura had been bottled up in the eponymous Miura Peninsula (in modern Kanagawa Prefecture) before being destroyed with the capture of their final fortress at Misaki Castle.

    Soun would engage in several further campaigns, even crossing into modern Chiba, but in 1518, he handed control of the clan over to his son, Ujitsuna, before passing away in August the following year.

    Hojo Ujitsuna, who would adopt the name and symbol of the Hojo after his father’s death.

    Though Soun himself would never take the name Hojo, his actions secured the dominance of his clan in the Kanto region for most of the 16th Century. Though they would never be completely unchallenged, the clan would eventually rise to become masters of the area around modern Tokyo, until they eventually fell foul of Toyotomi Hideyoshi’s campaigns to unite the realm, with their mighty fortress at Odawara being taken, and the clan destroyed in 1590.

    In many ways, Soun is the archetype of what would become known as a “Sengoku Daimyo”, a kind of warlord who was not content with simply fighting with his neighbours, but worked to improve the lands he ruled. In 1506, Soun ordered a land survey in Sagami Province, the first of its kind in this new era, and he would introduce sweeping reforms to law and justice in his territories that would serve as inspiration for generations of Samurai that followed him, and in some cases, formed the basis for the legal system in place during the Edo Period, and even into more modern times.

  • The Power in the Provinces Part One

    The Power in the Provinces Part One

    We’ve spent a lot of time talking about the breakdown of Shogunate power during the 15th Century. We’ve also discussed the three most powerful clans that were located closest to Kyoto during the Onin War. The Hosokawa, Yamana, and Hatakeyama Clans all played leading roles in the fighting, and in the aftermath, all three were seriously weakened.

    But what about the provinces? We’ve only spoken in very broad terms about what was going on out there, mostly because, to focus on it would require posts that resemble small novels, and keeping track of all those names and places is a task that is beyond most of us.

    In the interests of keeping things moving, then, I have generally neglected to go into much detail; however, since we’re now at the beginning of the Sengoku Jidai, a period of civil war lasting 120 years, we need to take a moment to look at who the main players are now that the Onin War is over.

    Central Japan

    Central Japan, corresponding mostly to the modern Kansai region, was the political and cultural heart of the nation.

    We’ve spent a lot of time looking at this region recently, so this is just a quick overview of who is still on the field in this part of Japan.

    The Hatakeyama Clan had been one of the main players, but a serious succession dispute fractured the clan and eventually led to the Onin War, as the Hosokawa and Yamana Clans supported rival claimants in a feud that would spiral out of control.

    By the end of the 15th Century, the Hosokawa remained largely in control of Kyoto, but they were already in decline. They would remain powerful, but a succession dispute (yes, another one) would divide the clan in the early 16th Century, and they’d never recover.

    The Yamana Clan had been badly mauled by the Onin War, and from a position as one of Japan’s mightiest clans, they’d eventually lose everything but a single province, which they’d manage to hold until the end of the 16th century, when some poor political decisions would see them forfeit even that.

    The Hatakeyama, for their part, were fragmented repeatedly throughout the late 15th Century, and they’d never recover their former power. However, some descendants would hold positions of power in Kyoto until the 1580s, when they’d run afoul of Oda Nobunaga, a name you should remember.

    Eastern Japan

    Eastern Japan, centred on the Kanto. Although home to Tokyo today, in the 15th Century it was Kamakura that was the centre of power in the region.

    The power in Eastern Japan was centred mostly around the Kanto Plain, with the political capital at Kamakura. In the period preceding the Ashikaga Shogunate, Kamakura had been the de facto capital of Japan, and even after the new Shogunate relocated to Kyoto, Kamakura remained the regional capital, and holding it was a prize in itself.

    The Kanto region was the source of a lot of trouble for the Ashikaga Shoguns, as there was the legacy of the previous Shogunate to contend with, and the strong, often semi-independent Kamakura Kubo to contend with. The kubo was the head of the local government, and they often openly defied the Shogun, who had to rely on the fickle loyalty of other powerful clans in the region to enforce his will.

    The Uesugi

    The dominant power in the Kanto in the 15th Century was arguably the Uesugi Clan. Like many others, the clan claimed descent from the illustrious Fujiwara Clan, and various members of the family would become shugo in and around the Kanto. Their most important role, however, was that of Kanto Kanrei, the Shogun’s deputy in the Kanto, a position that was supposed to complement that of the kubo, but in reality, often served as a check on Kamakura’s power, and frequently, a direct rival.

    Like most clans at this time, the Uesugi were divided into branches, three in this case, that were just as likely to fight as support each other. This infighting predated the Onin War, but the outbreak of general civil war saw the destruction of one branch, and the serious weakening of the other two, so much so that, in the early 16th Century, the Uesugi would lose their position in the Kanto to another rising power, the Hojo.

    The Uesugi would survive, however, and continue to play a major role in the Sengoku Jidai. The clan’s most famous son is arguably Uesugi Kenshin, who would engage in a rivalry with fellow warlord Takeda Shingen that became the stuff of legend. Mythology aside, Kenshin would die without heirs, and a succession crisis would severely weaken the clan.

    Uesugi Kenshin became a Samurai legend, but his death would leave the Uesugi in a weak position.

    Although they would survive, they chose the losing side in the final battles of the Sengoku Jidai and would end up in Yonezawa Domain, in modern Yamagata Prefecture, where they would actually prosper until the abolition of the Domains in the 19th Century.

    The clan endured into the modern day. The current head is Uesugi Kuninori, who was a professor at the Institute of Space and Astronautical Science until he retired in 2006.

    The Hojo

    The Mon of the Hojo Clan, and the later Hojo clan, who took the name and emblem for their own.

    The Hojo Clan, or more accurately the Go-Hojo, or Later Hojo, were relative latecomers to the scene. Although they would lay claim to illustrious ancestry (which was the style at the time), their progenitor was Ise Sozui (better known as Hojo Soun), who, despite being revered as the ancestor of the clan, never used the name Hojo himself. Traditionally, Soun was believed to have been a Ronin (masterless samurai) who rose to power seemingly out of nowhere in the aftermath of the Onin War.

    More recent scholarship, however, seems to indicate that Soun’s family, the Ise Clan, had a much longer history and would serve in the Shogun’s government in Kyoto before relocating to the Kanto later.

    Soun arguably deserves a post of his own, but the short version is that, he was originally in the service of the Imagawa Clan, another power in the region, before raising an army of his own and taking Izu Province for himself, establishing his base at Odawara Castle, which he took in 1494, some say, after tricking the previous owners, convincing them to leave on a hunting trip, and arranging their murders.

    It was his son, Ujitsuna, who renamed the clan to Hojo. You may remember that it was the Hojo Clan who acted as regents for the Kamakura Shoguns, rising to such power that they were effectively masters of Japan, before being overthrown by the Ashikaga.

    This new Hojo Clan was no relation to these regents, hence why they are referred to as the “Later” Hojo. Ujitsuna, apparently attempting to add some prestige to his family, adopted the name and mon (family crest) of the former Hojo, and everyone just went with it.

    Hojo Ujitsuna, who understood that there was power in a recognisable name.

    Ujitsuna wasn’t just savvy with brand recognition, however. Throughout the first half of the 16th century, he would guide the Hojo to become the predominant power in the Kanto. He would challenge and eventually drive out the Uesugi, taking control of their castle at Edo, which would eventually become the Imperial Palace in modern Tokyo.

    Throughout the Sengoku Period, the Hojo would continue to be masters of the Kanto, eventually becoming one of the greatest powers in the late 16th century, before they were eventually defeated by Toyotomi Hideyoshi in 1590. A branch of the family would survive as the lord of Sayama Domain (near modern Osaka) until the 19th century, and members of this family would continue playing a role in Japanese politics into the 20th century.

    The Takeda

    The Mon of the Takeda

    The Takeda also claimed descent from the Minamoto Clan, and from the earliest days of the Kamakura Shogunate in the 12th Century, they had established their power base in Kai Province (modern day Yamanashi Prefecture). Though they were a relatively minor player (one amongst many, you might say), the Takeda would develop a difficult relationship with the Uesugi Clan.

    When the Uesugi rose up against the Kamakura Kubo in 1416 (the Zenshu Rebellion), some members of the Takeda sided with the Uesugi, whilst others remained loyal to the government. The Uesugi were eventually defeated, but there was now bad blood between the Takeda and Uesugi that would last for another 120 years.

    The best known Takeda was certainly Takeda Harunobu, better known to history as Takeda Shingen. He is widely regarded as one of the best leaders of the Sengoku Period; indeed, some scholars have speculated that, had it not been for his sudden death in 1573, we might now be talking about Shingen as one of the great unifiers of Japan.

    Takeda Harunobu, better known as Shingen. Arguably one of the Sengoku Period’s best leaders, his sudden death brought an end to his ambition and seriously weakened the Takeda Clan.

    Alas, it wasn’t to be. Shingen was succeeded by his far less capable son, Katsuyori, who would lead the Takeda to disaster at the Battle of Nagashino in 1575, and the clan would cease to have any meaningful power after a final campaign led by Oda Nobunaga in 1582.

    Much like other major clans of the era, the Takeda Clan would live on in much reduced straits, eventually becoming direct vassals of the Tokugawa Shoguns, receiving a stipend of just 500 Koku a year. For reference, a Daimyo (great lord) could only claim that rank if he controlled lands worth 10,000 Koku a year or more. The Takeda had once controlled lands that were estimated to produce 1.2 million Koku, which gives you some idea of how far they had fallen.

    The Rest

    There are still several other regions to cover, and many more clans, but we’ll cover them next time.
