The Demon King and the Monks: Oda Nobunaga’s War on Buddhist Power

In the autumn of 1571, the Jesuit missionary Luís Fróis sat down to write a letter that practically vibrates with joy. A Buddhist monastery had just been burned to the ground. Somewhere between three and four thousand people, monks, laymen, women, children, scholars, had been killed in the conflagration. And Fróis, a man of the cloth, a servant of Christ, a representative of an institution that preached universal love, described the massacre as if it were the happiest news he had received since arriving in Japan.

He thanked God for it. He praised the omnipotence that had arranged it. He deliberately adjusted the date of the attack by a single day so that it would fall on the Feast of Saint Michael the Archangel, transforming a brutal military campaign into a providential act, an angel of God sweeping demonic forces out of the land.

The monastery was Enryakuji on Mount Hiei. The man who burned it was Oda Nobunaga. And the story of why a Jesuit missionary celebrated the destruction of one of the most ancient sacred sites in Asia tells you nearly everything you need to know about the extraordinary, violent, and deeply strange politics of religion in sixteenth-century Japan.

Chapter One

The Problem with Monks

To understand what Nobunaga did to Japanese Buddhism, you first have to understand what Japanese Buddhism had become by the time he arrived on the scene. And what it had become, by the mid-sixteenth century, was something far removed from what Siddhārtha Gautama would have recognized in his teachings.

The great Buddhist institutions of Japan, the Tendai school on Mount Hiei, the True Pure Land confederations scattered across the central provinces, the Shingon monks of Mount Kōya, the combative Nichiren fellowships in the capital, were not merely religious organisations in the way that a modern reader might understand the term. They were political states within a state. They maintained standing armies. They controlled enormous landholdings. They operated autonomous cities. They taxed trade routes, sheltered fugitives, and intervened in secular politics with the cheerful impunity of men who believed they had several hundred Buddhas and bodhisattvas on their side.

The warrior monks, the sōhei, were the most visible expression of this power. Dressed in robes and armed with naginata, bows, and, increasingly, firearms, they had been a feature of Japanese politics for centuries. The sōhei of Mount Hiei had a particular talent for marching on Kyoto whenever the imperial or shogunal court did something they disliked, carrying the sacred mikoshi of the Hie Shrine before them in the certain knowledge that no one would dare attack a procession bearing the vessel of a deity. It was, as political tactics go, magnificently cynical, a spiritual protection racket conducted at the point of a halberd.

Then there were the jinaimachi, the fortified temple-towns that Buddhist institutions operated as independent economic zones. These walled communities collected their own taxes, enforced their own laws, and answered to no secular authority. They were, in effect, theocratic city-states embedded in the feudal landscape, each one a small hole in the fabric of any daimyō’s sovereignty.

The toll barriers were another source of irritation. Buddhist monasteries had for centuries maintained sekisho, checkpoints along major trade routes where merchants were required to pay for the privilege of moving their goods through territory the monasteries claimed to protect. For a warlord with ambitions to unify the country and liberalise trade, these barriers were not just inconvenient. They were evidence that someone else still controlled the roads.

Oda Nobunaga looked at this landscape, the private armies, the autonomous towns, the economic strangleholds, the blithe interference in secular affairs, and saw not a religious establishment but a collection of rival governments. His ambition was to establish supreme secular authority over central Japan. Every institution that exercised independent power was, by definition, an obstacle. That many of these institutions happened to be religious was, from Nobunaga’s perspective, entirely irrelevant.

Chapter Two

A Man Who Believed in Nothing

Understanding Nobunaga’s war on Buddhist power requires grasping something essential about the man himself: he did not believe in anything.

This was not a private agnosticism politely maintained for the sake of appearances. Nobunaga’s irreligion was open, aggressive, and, to many of his contemporaries, genuinely shocking. According to both Jesuit and Japanese sources, he expressed frank disbelief in the existence of a Creator, the immortality of the soul, and any form of afterlife. Luís Fróis, who knew him personally and studied him with the avidity of a man taking notes on a particularly fascinating insect, compared his arrogance to that of Nebuchadnezzar. Nobunaga, Fróis reported, demanded veneration as the author of nature and the lord of the universe.

This was not metaphor. Nobunaga would, in the final years of his life, commission the construction of a temple at Azuchi dedicated to the worship of himself, complete with a sacred stone that he declared to be the physical embodiment of his divine essence. Visitors were promised wealth, health, children, and long life if they came to worship. Those who refused were threatened with perdition. He replaced the traditional Bon festival, the annual Buddhist ceremony honouring the ancestors, with an elaborate festival honouring himself. It was megalomania on a scale that even the sixteenth century found excessive.

But this was later. In the 1560s and early 1570s, Nobunaga did not hate Buddhism as a system of belief. He hated it as a system of power. The monks of Mount Hiei had sheltered his enemies, the Asai and Asakura clans, providing them with sanctuary when Nobunaga was trying to destroy them. The Ikkō-ikki had declared him an enemy of the Buddhist Law and mobilised tens of thousands of armed believers to fight him. The Nichiren preachers stirred up riots and public confrontations in his cities.

Nobunaga’s response to these provocations would be, by any measure, disproportionate. But proportionality was never part of his responses.

Chapter Three

Fire on the Mountain

The Tendai monastery of Enryakuji sat on top of Mount Hiei like a crown on the head of the capital. Founded in 788 by the monk Saichō, it had been the beating heart of Japanese Buddhism for nearly eight centuries, a vast complex of roughly four hundred temples, libraries, dormitories, and halls of prayer, spread across the forested summit overlooking Kyoto. Generation after generation of Japan’s intellectual elite had trained there. Emperors had patronised it. Shōguns had feared it.

By 1571, the relationship between Nobunaga and Enryakuji had passed beyond repair. The mountain’s monks had repeatedly harboured the Asai and Asakura, providing the coalition that was trying to crush Nobunaga with a sanctuary he could not touch, or so they believed. For a monastery that had spent centuries reminding secular rulers of its sacred inviolability, the calculation was straightforward: no one had ever dared to attack Mount Hiei. No one would.

On September 30, 1571, Nobunaga attacked. The attack was not a raid. It was a systematic operation, conducted over several days, designed to eliminate Enryakuji as a functioning institution. The troops began by burning the towns at the base, the commercial settlements that served the monastery and housed its lay dependants. Then they advanced upward through the forested slopes, torching everything they found. The main complex on the summit fell on the thirtieth. The Yokawa section, a satellite cluster of temples on the mountain’s northeastern slope, was destroyed the following day. The fires reportedly burned for four days before Nobunaga withdrew his troops around October 8.

Estimated casualties range from three to four thousand dead. Among them were approximately fifteen hundred monks, but the killing was indiscriminate. Women, children, and scholars who had sought refuge in the monastery, trusting in the same sacred inviolability that the monks themselves had counted on, died alongside the clerics. Fróis, who described the complex as the “university of Hieizan”, noted the destruction of every hall of prayer, every pagoda, every cloister, every rectory, every chapel. Nothing was spared.

The shockwave was immediate and, in Japanese society, nearly universal. Court noble Yamashina Tokitsugu recorded his horror in his diary, calling the destruction of Enryakuji an assault on the Buddhist Law itself. Another courtier wrote in evident disbelief that such a thing was simply not what a secular ruler ought to be doing. Takeda Shingen, the formidable daimyō of Kai province, denounced Nobunaga’s action as the most heinous of sacrilegious crimes, a violation of buppō-ōbō, the ancient principle that the Buddhist Law and the imperial state existed in mutual dependence. Shingen positioned himself as an avenger of the native deities, marching toward the capital in 1573 with promises to rebuild the monastery and restore the shrines of Sakamoto.

Even Nobunaga’s own vassals had tried to stop it. Akechi Mitsuhide and Sakuma Nobumori, senior commanders, men whose obedience was otherwise total, had advised against the attack and pleaded for the lives of the non-combatants. Nobunaga ignored them entirely.

But in the converted churches and cramped residences of the Jesuit mission, the reaction was ecstatic. The missionaries viewed Mount Hiei’s monks as the most formidable obstacle to the spread of Christianity in Japan, which, to be fair, they were. Fróis’s deliberate misdating of the attack to coincide with the Feast of Saint Michael was a masterstroke of propaganda, reframing a secular massacre as a cosmic battle between heaven and hell. Nobunaga was cast as a scourge sent by God, a pagan instrument of divine will sweeping the demonic bonzes from the land.

It was, theologically speaking, an extremely convenient interpretation. It also had the advantage of not requiring Fróis to engage with the moral implications of what had actually happened.

Chapter Four

The Longest War

The burning of Mount Hiei was a single, devastating strike against a single institution. The war against the Ikkō-ikki was something else entirely: a decade-long campaign of grinding attrition against the most formidable religious-military organisation in Japan.

The Ikkō-ikki, literally, “single-minded leagues”, were confederations of the True Pure Land Buddhist sect, the Jōdo Shinshū. They were not a monastic order in the conventional sense. Their membership was drawn primarily from the laity: farmers, merchants, local warriors, and townspeople who were bound together by fanatical devotion to Amida Buddha and absolute obedience to their chief priest. The sect’s headquarters, the Ishiyama Honganji in Osaka, was not a serene mountaintop retreat but a heavily fortified temple-fortress, surrounded by fifty-one defensive outposts and protected by expansive mud flats that made a direct assault almost suicidally difficult.

The man at the centre of this apparatus was Kennyo Kōsa, the eleventh chief priest of the Honganji. Kennyo was part religious leader, part military strategist, and part political impresario. He had initially pursued a cautious policy of accommodation with Nobunaga, but in October 1570, after Nobunaga attacked several of his daimyō allies, Kennyo made a decision that would commit his followers to ten years of catastrophic warfare.

He branded Nobunaga the “enemy of the Buddhist Law”, hōteki, and issued a general call to arms.

The power of this declaration can hardly be overstated. Kennyo was not merely asking his followers to fight. He was promising them that death in battle against Nobunaga was a guaranteed path to paradise. The Pure Land doctrine taught that salvation came through faith in Amida Buddha’s vow to save all sentient beings. Kennyo weaponised this theology, declaring that those who died fighting the enemy of the Law would be reborn immediately in Amida’s Western Paradise. Those who refused to fight would be excommunicated, kanki, and condemned to hell.

The result was an army motivated by something far more powerful than feudal obligation or territorial ambition. The Ikkō monto fought with the fanaticism of believers who genuinely did not fear death, because death, in the cause of the Law, was not a loss but a promotion. Nobunaga had faced samurai armies, peasant levies, and warrior monks. He had never faced anything quite like this.

Kennyo also proved to be a gifted coalition-builder. He assembled a sprawling anti-Nobunaga league that drew in the Asakura, the Asai, the Takeda, and the Mōri clans, creating a multi-front war that stretched Nobunaga’s resources to their limits. The Honganji’s alliance with the Mōri clan was particularly dangerous: the Mōri controlled the Inland Sea, and their fleet could resupply the Honganji by water, making a simple land siege ineffective.

The war unfolded across multiple theatres and a full decade. Its three bloodiest chapters, the Nagashima campaigns, the Echizen massacres, and the siege of the Honganji itself, reveal the escalating brutality with which Nobunaga approached a conflict that refused, year after year, to end.

Chapter Five

Nagashima, or the Education of a Warlord

The Nagashima fortress complex in Ise province was one of the Ikkō-ikki’s most formidable strongholds, a cluster of fortified positions set in the marshy delta of the Nagara and Kiso rivers, where the terrain itself was a defensive weapon. Getting an army to the walls meant crossing waterlogged ground that swallowed horses and broke formations. The defenders knew every path through the marshes. The attackers did not.

Nobunaga tried three times.

The first campaign, in 1571, was a humiliation. His forces advanced into the delta and found themselves outmanoeuvred on terrain they did not understand by defenders who fought with the fury of the devout. Nobunaga was forced to retreat with heavy losses. It was one of the few outright defeats of his career.

The second campaign, in 1573, produced no better result. Nobunaga brought more men and applied more pressure, but the Nagashima fortifications held. The monto simply would not break. The inconclusive result was, for a warlord of Nobunaga’s temperament, worse than a defeat, it was an embarrassment, evidence that a collection of peasant zealots and provincial warriors could defy the most powerful military machine in Japan.

The third campaign, in August 1574, was Nobunaga’s answer to two years of frustration, and it was terrible.

He encircled the fortress complex completely, by land and by sea, cutting off every avenue of supply and every route of escape. Then he waited. Starvation took hold inside the walls. When the defenders were sufficiently weakened, Nobunaga’s troops set fire to the fortified positions. The resulting conflagration consumed tens of thousands of people. Those who survived the flames and attempted to surrender were not accepted. Approximately 12,250 prisoners were executed in the aftermath.

The third Nagashima campaign established a pattern that would define Nobunaga’s approach to the Ikkō-ikki for the remainder of the war: not conquest, but annihilation. Traditional warfare between daimyō was conducted with the understanding that the losers would submit, the winners would accept the submission, and life would continue under new management. Nobunaga fought the Ikkō-ikki with the aim of destroying them. He was not trying to win their surrender. He was trying to ensure there was no one left to surrender.

Chapter Six

The Killing Fields of Echizen

In 1574, the Ikkō-ikki had seized control of Echizen province, overthrowing the secular administration and establishing a theocratic government under sect leadership. For Nobunaga, this was an intolerable provocation, an entire province lost to a religious insurrection.

He waited. In June 1575, he won the Battle of Nagashino against the Takeda clan, deploying massed volley fire from ranks of matchlock-armed ashigaru, a tactical innovation that shattered the Takeda cavalry and demonstrated to every warlord in Japan that the age of the mounted charge was over. With the Takeda threat neutralised, Nobunaga turned his full attention to Echizen.

In August 1575, his forces poured into the province. What followed was not a military campaign in any conventional sense. It was a manhunt. The Ikkō monto, recognising that pitched battle against Nobunaga’s armies was suicide, dispersed into the mountains and valleys of Echizen’s rugged interior. Nobunaga’s troops followed them. Through every mountain path, every remote valley, every village where the sectarians had sought refuge, the soldiers pursued and killed.

The casualty figures are staggering even by the standards of the era: between thirty and forty thousand Ikkō monto were killed in the Echizen operations. These were not soldiers in the conventional sense. Many were farmers, townspeople, women, and children, the entire civilian population of a religious movement being exterminated.

Chapter Seven

The Fortress on the Mud Flats

The epicentre of the Ikkō-ikki war was always the Ishiyama Honganji itself. Every campaign Nobunaga fought against the sect’s regional fortresses was, in strategic terms, a preliminary operation, an effort to isolate the central stronghold from its sources of supply and reinforcement before the final reckoning. That final reckoning took ten years.

The Honganji was a fortress of extraordinary strength. Its position on the site that would later become Osaka Castle, surrounded by rivers and mud flats, made it nearly impervious to direct assault. The garrison numbered up to fifteen thousand defenders, and among them were the Saiga tepposhu, matchlock specialists from Kii province who were among the finest gunners in Japan. Their fire was devastating. Frontal attacks against the Honganji were not battles but execution grounds.

Nobunaga’s strategy was blockade. He established a ring of forts around Osaka and attempted to starve the Honganji into submission. The plan was sound in theory. In practice, the Mōri clan’s navy rendered it irrelevant. In August 1576, at the First Battle of Kizugawaguchi, a Mōri fleet of seven to eight hundred ships smashed through Nobunaga’s blockading vessels with incendiary weapons and resupplied the temple-fortress with food, ammunition, and reinforcements.

Nobunaga’s response was one of the most audacious technological innovations of the Sengoku period. He ordered his naval commander, Kuki Yoshitaka, to construct a squadron of massive iron-plated warships, ōatakebune, armed with heavy cannons. These were, in effect, the first armoured warships in Japanese history, floating fortresses designed to be invulnerable to the fire ships and incendiary tactics that had destroyed the first blockade fleet.

In December 1578, at the Second Battle of Kizugawaguchi, Kuki Yoshitaka’s ironclads met a Mōri fleet of six hundred vessels and annihilated it. The iron plating deflected the Mōri’s incendiary projectiles. The heavy cannon tore through wooden hulls at ranges the Mōri could not match. The supply line to the Honganji was permanently severed.

Starved of provisions, watching his daimyō allies fall one by one to Nobunaga’s expanding campaigns, Kennyo finally capitulated in April 1580. The surrender was mediated by the imperial court, a face-saving mechanism that allowed the chief priest to yield without the appearance of total submission. Kennyo agreed to vacate Osaka. His son, Kyōnyo, held out for a few more months out of stubborn defiance before evacuating in August. As the Honganji was handed over, it burned, whether by accident or by the departing garrison’s hand, the sources disagree.

The decade-long war was over. The most powerful religious confederation in Japan had been dismantled. The site where the Honganji had stood would soon be occupied by a different fortress, built by a different man: Toyotomi Hideyoshi’s Osaka Castle, the greatest military engineering project in Japanese history, raised on the ashes of a Buddhist republic.

Chapter Eight

Settling Scores

The destruction of Enryakuji and the Ikkō-ikki were the centrepieces of Nobunaga’s war on Buddhist power, but they were not its totality. Nobunaga’s hostility extended to any religious institution that crossed him, regardless of sect, and his definition of “crossing him” was extraordinarily broad.

Hyakusaiji, a prominent Tendai temple in Ōmi province, offers a representative case study in the mechanics of Nobunaga’s wrath. In 1568, Nobunaga had actually favoured the temple, granting it tax exemptions and designating it as his personal patron temple, kigansho. The relationship was cordial. And then, in the spring of 1573, Hyakusaiji answered a call to arms from the exiled Shōgun Ashikaga Yoshiaki and the Rokkaku clan, joining a military campaign against the man who had been its patron.

The response was swift and total. On May 12, 1573, Nobunaga’s forces burned every building in the complex to the ground. There was no negotiation, no opportunity to reconsider, no appeal to the temple’s long history or its previous relationship with the warlord. Hyakusaiji had sided with his enemies. Hyakusaiji ceased to exist.

In the fall of 1581, Nobunaga mobilised one hundred and thirty-seven thousand troops against Mount Kōya, the Shingon monastery complex that was to esoteric Buddhism what Mount Hiei had been to the Tendai school. The mountain was defended by approximately thirty-six thousand warriors. As a prelude to the planned assault, Nobunaga ordered the execution of 1,383 hijiri, itinerant holy men associated with the mountain who wandered the provinces collecting alms and spreading the faith. Only Nobunaga’s assassination the following year prevented Mount Kōya from sharing Enryakuji’s fate.

The most haunting of these secondary campaigns came in April 1582, just two months before Nobunaga’s own death. The Zen temple of Senrinji in Kai province had provided sanctuary to Rokkaku Yoshisuke, an ally of the Takeda clan, and to former vassals of the deposed Shōgun. Nobunaga ordered his troops to surround the temple and set it ablaze. Approximately 150 to 180 priests were driven inside and burned alive. Among them was the temple’s chief priest, Kaisen Jōki, who, according to the sources, sat in calm meditation as the flames consumed the building around him, offering a single observation as his epitaph: for those who have extinguished their minds, even fire itself is cool.

The Azuchi Religious Debate of June 1579, covered in detail in a separate article in this series, extended Nobunaga’s campaign of suppression into the realm of theological theatre. By rigging a formal disputation between the Nichiren and Jōdo schools, Nobunaga humiliated the Nichiren sect, executed three men, and forced thirteen surviving dignitaries to sign a blood oath renouncing their defining practices. It was the bureaucratic complement to his military operations: where the armies destroyed the institutions’ physical power, the debate destroyed their public credibility.

Chapter Nine

Dismantling the Machine

Nobunaga understood, and this was what separated him from a merely violent man, that Buddhist institutional power rested on economic foundations as much as military ones. An army of warrior monks could be defeated in the field. The wealth that recruited, armed, and fed that army required a different kind of assault.

His economic campaign against the Buddhist establishment was as systematic as his military one. He confiscated the vast landed estates, shōen, that had sustained temples and monasteries for centuries, redistributing the income to loyal vassals who owed their wealth entirely to Nobunaga’s patronage. He stripped temples of their shugo fu’nyū rights, the traditional privilege of receiving a share of provincial tax revenues. He abolished the network of toll barriers that Buddhist institutions had maintained along major trade routes, a reform that served the dual purpose of undermining monastic revenue and liberalising commerce, since the rakuichi-rakuza free-market policies that followed were enormously popular with the merchant class.

The autonomous temple-towns and gate-front towns, the jinaimachi and monzenmachi that had operated as independent economic centres under Buddhist control, were brought under direct secular administration. Their walls were torn down. Their courts were dissolved. Their residents became subjects of the secular state, taxed and governed like everyone else.

The cumulative effect was devastating. Even institutions that survived Nobunaga’s military campaigns emerged economically gutted, stripped of the revenue streams that had sustained their independence for centuries. A monastery without land, without toll income, without tax privileges, and without its own town was a monastery that depended on the goodwill of the secular power.

Chapter Ten

The Useful Christians

Into this landscape of burning temples and broken monasteries walked the Jesuits, and they found it wonderfully congenial.

Nobunaga’s relationship with Christianity is explored at length in the articles on the 1579 Azuchi Debate and the Christian Century, but its relevance to his war on Buddhism cannot be left unmentioned, because the two campaigns were, in Nobunaga’s strategic calculus, complementary instruments of the same policy.

Nobunaga first met Luís Fróis in 1569, on the drawbridge of the newly constructed Nijō Castle in Kyoto. The warlord appeared wearing a tiger or leopard skin, surrounded by a bodyguard fierce enough to intimidate even a man who had spent years in the courts of Goa and Malacca. The two bonded quickly over their shared contempt for the Buddhist clergy. Nobunaga treated the Jesuit with a familiarity and intimacy that shocked his own retainers, men who lived in daily terror of their lord’s capricious temper, entertaining him with chamber music and, on one occasion, a performance by a dancing dwarf.

Nobunaga admired things about the Jesuits that were immediately useful to his purposes. Their strict self-discipline and personal austerity stood in stark contrast to the worldly, arms-bearing Buddhist bonzes, and Nobunaga was not above pointing this out in public. When Buddhist monks petitioned the Emperor to have Fróis expelled from Kyoto, Nobunaga intervened personally, humiliating the petitioners and reinforcing his protection of the foreign mission. The message was unmistakable: the Christians were under his protection, and anyone who interfered with them was interfering with him.

But the patronage was transactional, not theological. Nobunaga promoted Christianity precisely because it was useful as a counterweight to militant Buddhism. The Jesuits taught a doctrine of passivity, hierarchical obedience, and acceptance of suffering, qualities that made their converts the opposite of the armed religious leagues Nobunaga was fighting to destroy. Every church he permitted, every letter-patent he issued guaranteeing the Jesuits’ freedom to preach, was a calculated provocation against the Buddhist establishment. The Christians were useful because they were foreign, because they owed nothing to Japan’s existing religious power structures, and because their mere presence in Nobunaga’s domains was a daily reminder to every monk in Japan of who held the real power.

The Jesuits, for their part, understood the transaction perfectly and embraced it with enthusiasm. Because they viewed Japanese Buddhism as a creation of the Devil, a sinister mimicry of Christianity designed to enslave the nation, they regarded Nobunaga’s massacres of Buddhist monks not as atrocities but as acts of divine providence. The destruction of Mount Hiei was celebrated as a heavenly intervention. The decade-long war against the Ikkō-ikki was interpreted as God clearing the path for the Gospel. The tens of thousands of dead were, in the Jesuit telling, casualties of a cosmic war between truth and darkness.

Chapter Eleven

The Living God of Azuchi

In the final years of his life, Nobunaga’s megalomania reached an altitude that alarmed even his admirers. Having spent a decade destroying every independent religious authority in central Japan, he moved to fill the vacuum with the only deity he considered worthy of worship: himself.

Near his magnificent castle at Azuchi, the first great stone castle in Japanese history, a seven-storey tower sheathed in gold and decorated with paintings by Kanō Eitoku, Nobunaga ordered the construction of a temple called Sōken-ji. He gathered some of the most celebrated Buddhist icons from across Japan and placed them inside. Then he placed something above them all: a sacred stone, a shintai, the kind of object traditionally understood to house the essence of a deity. Nobunaga declared that this stone represented himself. He was, in his own proclamation, greater than any kami or Buddha.

An inscription at the temple promised extraordinary rewards to the faithful. The rich would grow richer. The poor would find fortune. The childless would gain descendants. The sick would be healed. Those who worshipped would live to a hundred years in perfect peace. Those who refused were threatened with perdition in this life and the next. Nobunaga declared his birthday a solemn national holiday, commanding men and women of all classes to make pilgrimage to Sōken-ji.

During the Bon festival, the most important Buddhist ceremony in the calendar, the annual celebration honouring the ancestral dead, Nobunaga replaced the customary religious observances with a spectacular illumination glorifying himself. Lanterns, fires, festivities, all centred on his veneration rather than the spirits of the departed. It was a direct assault not merely on Buddhist institutional power but on the devotional life of the entire population.

Whether Nobunaga genuinely believed himself divine, or whether the self-deification was the logical endpoint of a political strategy designed to concentrate all authority, spiritual as well as temporal, in a single person is a question the sources cannot conclusively answer. What can be said is that his contemporaries, both Japanese and European, took the claim at face value. Fróis described it with a mixture of fascination and horror. Japanese diarists recorded it with bewilderment. No secular ruler in Japanese history had ever attempted anything like it.

The experiment lasted less than two years. On the morning of June 21, 1582, Nobunaga was staying at the Honnōji temple in Kyoto with a minimal guard when his vassal Akechi Mitsuhide surrounded the building with thirteen thousand troops. Nobunaga, realising escape was impossible, retreated into the burning temple and died. The living god of Azuchi had lasted exactly forty-eight years.
