Stephen Turnbull believes that ''Amagoisan'' describes the second invasion by Oda Nobunaga in 1581, specifically the force led by Gamō Hidesato along Tamataki route from Kōka.
There also is an extant constitution with an unclear provenance and no specific date or year. It was preserved in Kōka by the Yamanaka family but was attributed to Iga by the historian Ishida Yoshihito because it refers to a "self-governing league" - ''sokoku ikki'' -, which is what Iga referred to itself as.
Based on references within the document, Yoshihito deduced that it was composed between 1552 and 1568.
History
Formation
In 15th and 16th century Japan, Iga Province contained some 300-500 small estates and 700 castles and nearby Kōka, in
Ōmi Province, had some 53
clans

, their estates and families constantly engaged in low-level, small-scale feuds and squabbles within and between each region.
In Iga, fighting was constant from at least the late 13th century.
Bandits also frequently raided the local monasteries.

'' posed external threats to Iga. These threats and the banditry necessitated that the local ''
jizamurai'' (high-ranking peasant warriors) form an alliance and develop specialized combat, espionage, and
guerilla warfare skills in order to restore peace and order to the province.
The remoteness of the hill country in this part of Japan might also have encouraged the development of these skills.
Iga was surrounded by mountains and accessible mostly only by narrow paths that permitted only one horse-rider at a time. The militant mountain-monks, ''yama-bushi'', were also likely an influence as even the bandits in the area wore yellow scarfs that seem to have been copies of those worn by the mountain monks.
Reputedly, the units from these two regions often offered their services to nearby provinces as professionally trained, highly trained mercenaries.
Specifically, the Iga professionals were sought after for their skill at siege warfare, that is, ''shirotori'', which included night attacks and ambush. The legendary general
Kusunoki Masashige was said to have employed soldiers from Iga to infiltrate and reconnoiter Kyoto in the early 14th century.
Turnbull in 2007 argued that this market in mercenary work could have been a motivator for exaggerating the abilities of ninja. However, in 2017, Turnbull questions the existence of such a market at all, contending that, contrary to the mercenary narrative, political self-interest, including continued survival, could also have equally motivated the activities of Iga units in these provinces. The usages of the term ''shinobi'', specifically ''shinobi-mono'', later known as
ninjas, appearing in the late 1580s and early 1600s, referred to the soldiers from Iga and Kōka. The isolation in these two regions encouraged autonomy, and the communities began organizing into ''ikki'' - "revolts" or "leagues".
Late 15th century
By 1477 Iga was known for rejecting the authority of the military governors - ''
shugo'' - appointed by the shogun,
and by around 1500 they had formed an ''ikki'' - a "league".
Instead of a local ''daimyo'' from an aristocratic family replacing the ''shugo'', leadership remained divided among the ''jizamurai'' and they formed a league.
Records of their military unit, ''Iga-shū'', appear as early as June 1470, when they assisted the
Hatakeyama clan in an attack in the fields outside the
Negoro-ji in
Wakayama.
Another reference to the ''Iga-shū'' appears in 1482.
In October 1485, Iga ''kokujin'' – another term for ''jizamurai'' – helped the Hatakeyama defend Mizushi-castle in the neighboring
Yamato Province.
In 1487, the ninja from Iga and Kōka gained significant fame due to their actions at Magari, which is part of present-day
Rittō, Shiga.
Shogun
Ashikaga Yoshihisa, concerned about the aggressive landgrabs by the Kōka ''shugo'', Rokkaku Takayori, attacked Takayori. At Magari, Iga and Kōka ninja fought on the side of Takayori in exchange for Takayori recognizing their land ownership. The illness which prematurely killed Yoshihisa may have been at least hastened by, if not caused by wounds suffered during, the
guerilla tactics and night attacks by the Iga and Kōka units.
[; ; ; ] Iga troops again were involved with the Rokkaku in 1492.
Mid-16th century
By the mid-1500s, the services of ninja from Iga and Kōka were in high demand, in use by at least 37 areas. On December 15, 1541, the shogun in
Kyoto sent a letter to Iga's governor requesting that the province assist

Two days later, the armies inside Kasagi sallied out and were defeated, after which the ninjas dispersed.
On January 24, 1556, during the
Tsutsui siege of Takada Castle in
Yamato Province (the site of present-day Takada High School in
Yamatotakada, Nara), 11 Iga soldiers attacked the castle and both the castle and the nearby Jōkō-ji were set ablaze.

Stephen Turnbull, this account is full of errors, and accounts not derived from the ''Bansenshūkai'' do not mention ninja, let alone Tateoka Doshun, at all. Per the account,
Rokkaku Yoshikata was campaigning against an alleged rebel retainer, Dodo Oki-no-Kami Kuranosuke, and besieged him. After many days of unsuccessful siege, Yoshikata employed Doshun to aid him. Doshun led a team of 44 Iga ninja and 4 Kōka ninja who carried lanterns Doshun had made with replicas of Dodo's ''

'' (family crest). They entered the gates of the castle without opposition and then set fire to the castle. They escaped successfully and in the ensuing panic Yoshikata was able to capture the castle.
[; ] According to Turnbull, contrary to the account, Dodo in actuality was a retainer of the Rokkaku's enemies, the
Azai clan, and when Yoshikata invaded Northern Omi Province in 1559, Dodo was ordered by
Azai Nagamasa to hold Sawayama. The historian and travel writer
John Man, on the other hand, takes the account at face value and cites this as an example of the fame of the ninjas and of them offering their services for hire.
Around 1560, the confederacy drafted a constitution which included an outline for an alliance with Kōka.
Exactly how long the document was extent for, and how widely it applied to the villages of the region, is unknown.
In 1560, a highly influential leader within the confederacy, Shimotsuge no Kizaru, attacked Tōichi Castle (present-day
Kashihara, Nara), which was commanded by Hashio Shōjirō Tōkatsu. The general's residence was captured, forcing him to flee to Toyoda Castle with his retainer, Dōruku. A man named Ueda and four others were killed.
Conflict with Oda Nobunaga
The republic soon came in conflict with the rising power of
Oda Nobunaga

. In 1568, Nobunaga marched to Kyoto to install
Ashikaga Yoshiaki as shogun. The
Rokkaku clan in southern Ōmi Province allied with the
Miyoshi clan and backed Yoshiaki's nephew and rival,
Ashikaga Yoshihide, that the Miyoshi had installed in Kyoto. After
Rokkaku Jōtei and his sons were defeated during the invasion of
Kannonji Castle, they fled first to Kōka and then

. From there they staged a guerrilla war against Nobunaga, assisted by the Iga and Kōka ninja forces. The danger of harassment by this alliance made Nobunaga's control of southern Ōmi insecure, and in 1570 when Nobunaga retreated from the
Siege of Kanegasaki back to Kyoto he was forced to go along the north-west shore of
Lake Biwa rather than the more direct route through southern Ōmi.
''Jizamurai'' from Iga and Kōka assisted Jōtei and his sons in raids against Nobunaga, including setting fire to the village of Heso and the southern approaches of

.
On July 6, 1570, these alliance forces were moving down along the Yasugawa river when an army led by
Shibata Katsuie and
Sakuma Morimasa, generals for Nobunaga, intercepted them at the village of Ochikubo.
The alliance was defeated and 780 samurai from the Iga and Kōka ''ikki''s were killed, along with the father and son Mikumo Takanose and Mikumo Mizuhara. Stephen Turnbull estimates that 780 casualties must have been enormous for Iga and Kōka, since their armies likely were not very large, and indeed ''Shinchō Kōki'' makes no reference to that alliance for the next three years.
Around the same time, a monk named Sugitani Zenjūbō and who is presumed to have been a mercenary ninja assassin from either Iga or Kōka, ambushed Nobunaga, fired at him, but failed to successfully assassinate him. Turnbull states that Zenjūbō fired two shots at Nobunaga, both of which were absorbed by Nobunaga's armor.
Conversely,
John Man cites an interview with a local resident in Kōka City who contends that the monk was from Kōka and attempted only one shot, which missed narrowly missed Nobunaga and passed through his right sleeve. He was executed three years later.
In 1573, the shogun Yoshiaka attempted to thwart the power Nobunaga held over him and allied with the Rokkaku and the Kōka and Iga ''ikki''s.
Yoshiaki began constructing a castle next to Lake Biwa. The castle was half-finished and the garrison, which included Kōka and Iga troops, was small when Nobunaga attacked. The defenders fled and begged for mercy, and Nobunaga immediately demolished the castle. The same year, archers from Iga and Kōka assisted the
Ikkō-ikki against Nobunaga as he retreated from the
Second Siege of Nagashima. Yoshiaki continued his resistance to Nobunaga but in late summer, 1573, he was defeated and forced to surrender.
A later record states that in 1573 some ''Iga-shū'' supported Shibata Katsuie and other retainers of Nobunaga in defeating the
Azai clan in the
Siege of Odani Castle.
The following year, Nobunaga defeated Rokkaku and the Kōka ''ikki''. According to a document preserved by the Yamanaka family, on March 27, 1574, the remnants of the Kōka ''jizamurai'' surrendered to Nobunaga.
On May 3, Rokkaku Yoshikata, who had fled to Kōka, surrendered to Nobunaga.
Tenshō Iga War
The Iga ''ikki'' was destroyed in 1581 by Oda Nobunaga in the conclusion of the
Tenshō Iga War. The war began after the
Oda clan staged a coup on the territory of the
Kitabatake clan in the adjoining
Ise Province. The Kitabatake clan had recently commissioned a castle in the center of Iga, Maruyama, and with the Oda takeover, members of the Kitabatake family took refuge in Iga and sought aid from

. In 1579
Oda Nobukatsu launched an invasion to take the unfinished castle in Maruyama and subjugate Iga.
The campaign proved disastrous for Nobukatsu, who had underestimated the mix of peasants and local warriors: the effectiveness of their tactics, their strategic advantage conveyed by their knowledge of the local terrain, and their capacity for organization and
mobilization.
[; ] The historian
Stephen Turnbull summarized the defeat as "one of the greatest triumphs of unconventional warfare over traditional samurai tactics in the whole of Japanese history."
Nobunaga was enraged at his son and told him that his biggest mistake was not to use ninjas in his assault on Iga.
In 1580, Iga counter-attacked by covertly infiltrating
Sakaibe Castle.
In the middle of the night, they crossed the wet moat from the south and were the first to arrive at each entrance. According to the narrator of the incident, Ichiborō, to enter the castle was an "event without parallel."
In 1581, ninja were sent out on an
espionage mission, holding captives for ransom in order to accomplish the mission.
The resistance by Iga was not left unpunished. Nobunaga personally led a much larger army of 40,000-60,000 on a second invasion in 1581, guided by two samurai from northeast Iga and attacking from seven sides.
Troops from Kōka are mentioned among Nobunaga's forces, indicating that its surrender in 1574 had forced it to terminate the alliance with Iga and instead oppose that confederacy.
This time the invasion was successful. The guns and cannon employed by Nobunaga crushed the earth-and-wood fortresses of Iga.
Last stands were made at Hajiyama, near Ueno, and at Kashiwara Castle, near Maruyama. After some initial success in defending themselves, the forces at Hajiyama were then trapped inside the complex of fortifications and temples as they were set on fire. Takino Jurobei commanded the final stand at Kashiwara.
When defeat was imminent, he surrendered the fort and he, his officers, and half the population of the castle fled.
Because of Iga's fierce resistance in this and the prior invasion, the political and social structures that it had created were destroyed, and most of the temple, forts, and villages in Iga burned.
Some ninja fled to the mountains of
Kii Province, while many others took shelter in
Mikawa Province, where they served
Tokugawa Ieyasu.
Sporadic guerrilla resistance continued for years and was ended when Tokugawa integrated the Iga forces into his military as auxiliaries.
A castle was constructed in Ueno in 1585 by Tsutsui Sadatsugu.
It was severely damaged by a storm in 1612, and then gradually abandoned. It was reconstructed in 1935.
Subsequent ninja activities
Purported Tokugawa escape through Iga
Many of the Iga and Kōka ninja offered their services to Tokugawa Ieyasu after
Oda Nobunaga was assassinated In June 1582.
Specifically, it was reported by Edo period traditional records that
Hattori Hanzō, a Tokugawa vassal from Iga, negotiated with Iga ninjas to hire them as guards to help Tokugawa escape to
Kii Province and avoid capture by
Nobunaga's assassin.
The local Kōka and Iga ninjas under Hanzo who allegedly helped Ieyasu to travel into safety consisted of 300 soldiers.
Modern Japanese historians such as Tatsuo Fujita have expressed doubts about the credibility of story regarding Hattori Hanzō's ninja helping Ieyasu, given that the story does not appear until the 18th century during the rule of
Tokugawa Yoshimune.
Edo period activities
Ninja activities continued in Iga into the 17th century, servicing the Tokugawa shogunate.
Fujibayashi Yasutake, a member of the Fujibayashi family which was a prominent ruling family in Iga, composed the ''
Bansenshūkai'', an anthology he alleged contained the collective knowledge of ninja skills and history in Iga and Kōka, in 1676.

During
Ieyasu's campaigns to unite Japan under his authority, many ninja from Iga and Kōka contributed their skills. After the establishment of the Tokugawa shogunate, many ninja turned to farming in Iga and Kōka, while others went on to serve as castle guards. Those who served at the forefront of battles for Ieyasu were granted residential land in the vicinity of

Government and military organization
The Iga ''ikki'' functioned as a province-wide ''sō'', that is, individual villages banded together, similar to a
European medieval commune. Typically, including in Iga, the leadership of ''sō'' consisted of ''kokujin'' (the ''jizamurai'') and the ''dogō'' (villagers) and lesser farmers.
Pierre Souyri argues that the inhabitants of Iga and Kōka formed these collectives not out of a commitment to a particular ideology but out of necessity. The defeated ''jizamurai'' who took refuge in the area trained the local inhabitants and together they desperately fought to maintain their social status and autonomy. By 1477 Iga was known for rejecting the authority of the ''shugo.''
In times of military crisis, the ''shugo'' would sometimes temporarily exercise his powers in nearby
Yamato Province, which normally was under autonomous rule by
Kōfuku-ji via the authority of the
Fujiwara clan. Around the year 1560, a constitutional document was drawn up for Iga outlining principles of self-defense and participation of villages based on
voluntary association.
[; ; ] It also detailed an alliance and
defense pact with Kōka.
Eleven points were laid out in the constitution:
# The first article required the village collective, the ''sokoku'', to join as one to resist the invading armies from any other domain.
# The second article stipulated that whenever an alert is sent signaling that an enemy is spotted at a gate, all the villages should ring every bell, and every member should take up defensive positions and encamp with food, weapons, and shields.
# The third article
conscripted every person from age 17 through 50. For prolonged campaigns, article three called for a rotation system to be set up. Commanders were to be appointed in every village and area. The elders of the collective were to pray at the temples for prosperity of the province, and the young participants partake in the camps.
# Article 4 required the ''hikan'' (
retainers or servants) to swear loyalty to their lord regardless of the situation of the land.
# Article 5 granted permission for even ''
ashigaru'' (peasant infantry) to capture enemy castles and stated that ''ashigaru'' who successfully capture a castle in an enemy land would be promoted to
samurai.
# Article 6 laid out severe penalties for treason. If any member of the collective let in an invading army, or shared intelligence with any enemy, their entire clan would be annihilated. Any member of the collective who shared intelligence regarding someone's treason as outlined above would be generously rewarded.
# Article 7 forbade any ''ashigaru'' or samurai from serving the
Miyoshi clan.
# Article 8 stated that any member who refused to pay the ''Yumi Hanjo'' tax (presumably a war fund), they and their father, sons, and brothers would be ineligible for benefits from the fund for 10 years, and would be excluded from using the ''Yado Okuri'' or ''Mukae'' transport relay stations.
# The ninth article prohibited disorderly conduct or violence for anyone positioned in a village or camp within the borders of the alliance.
# Article 10 forbade the collective from hiring any ''
rōnin'' who formerly served in the military from
Yamato Province, due to that province's long-standing attacks against the collective.
# The eleventh article called for an alliance with Kōka
To coordinate the Iga–Kōka alliance, the respective confederacies frequently held "field meetings" along their border to discuss issues of governance and cooperation.
This co-operation within and between Iga and Kōka was in tension with constant petty feuds in each of the regions that helped contribute to the development of the leagues in the first place.
Leadership of the confederation was hierarchical: Military bands formed around the leadership of a lord.
They thus were composed of both peasants and ''jizamurai'', but the latter trained and oversaw the former''.''
The ninjas were divided between high and low classes and only the upper-class ninja were given the prestigious missions.
Though these class divisions were well-established, social mobility was possible as peasants who distinguished themselves in battle could be promoted to samurai.
Each band comprised from 100 to 300 men.
Even though the ''sō'' was embedded within a feudal hierarchy, it had

tendencies and the possibility of social mobility through promotion meant that class differences could be overcome. Informers and traitors were severely punished by confiscation of their property followed by beheading.
Overseeing the entire confederation was

elders among the ''jizamurai.'' John Man and Vladimir V. Maltsev claim that this council consisted of 66 members with a headquarters at the Buddhist temple, Heirakuji, in
Ueno (located at the present-day site of
Iga Ueno Castle).
This "parliament" of Iga also met in various locations throughout the province. Conversely,

argues that the bands of clans overseeing different portions of territory were overseen by 12 leaders known as ''hyojo-shu''.
According to the latter work, important decisions made by the ''hyojo-shu'' were circulated in writing among the various bands and representatives of those bands would pledge loyalty in various written forms, such as ''renbanjo'' joint agreements or ''kishomon'' pledges to gods.
The lords within Iga were highly independent. While they might have constantly negotiated master-subordinate relationships with ''daimyo'', they might also have independently worked as mercenaries on occasion.

and
voluntary government allowed Iga the stability to reap profits from its mercenary market while remaining effectively
stateless. In most of Japan after the Onin War, the loss of centralized power and the ensuing banditry, peasant uprisings, and feuds between and predatory taxation and raids by local ''daimyō'' resulted in insecure property rights, thin markets, and greatly weakened provision of public goods. In Iga and Kōka, this economic situation offered a lucrative mercenary market. Conventionally in economics, a formal state is deemed necessary to protect complex trade arrangements. However, Maltsev hypothesizes that in the chaotic and violent environment of the Sengoku period, state formation was cost-prohibitive and potentially hazardous to Iga.
Instead, the model of private government practiced by various ''ikki'' was much more attractive. Particularly as outlined in the c. 1560 constitution, the ban on violent altercations within the alliance and defensive measures against external invasion secured military protection, and the provision of relay stations and a war fund secured economic productivity.
Maltsev claims that the requirement and expectation of certain behaviors delineated in the constitution and the enumerated penalties, combined with a relatively homogenous identity in the mountainous region, constrained abusive behaviors. And the voluntary nature of the confederacy resulted in a

of government.
Okuse Heishichirō, the writer who in the mid-20th century greatly contributed to the development of ninja myth, outlined a three-tiered social structure in Iga. At the top were ''jōnin'', the head families. Depending on their wealth, the comparable rank of a ''jonin'' could range from that of a minor ''daimyō'' to a ''jizamurai'' village headman.
[; ] Below the ''jonin'' were the ''chunin'', the family's executive officers and leaders.
Turnbull in his 2003 and 2007 books on the ninja speculates that the famous commander
Tateoka Doshun was an intermediate-ranking Iga ninja during the Sengoku period. He is also known as Igasaki DoshunJoel Levy , ''Ninja: The Shadow Warrior'' or . Stephen K. Hayes, ''The Mystic Arts of the Ninja''
In 1558, during the siege of Sawayama, Tateoka D ...
was of this rank.
[; ] Below them were the ''genin'', the agents typically sent out on missions.
However, in Turnbull's 2017 revisionist work he notes the source for these terms, the ''Bansenshūkai'', lists these as skills rather than social rank. Thus, Turnbull argues, this ranking system could be of Okuse's own invention.
The documented ruling families were the Hattori and their cadet branches of Momochi and Fujibayashi.
Some of the most famous ninja commanders came from these families, namely the legendary figures
Momochi Sandayu, Fujibayashi Nagato no Kami, and
Hattori Hanzō, all three of whom Okuse labeled ''jōnin''.
John Man lists them as officers of Takino Jurobei. According to the ''Bansenshūkai'', the Momochi oversaw southern Iga, the Fujibayashi northeastern Iga, and the Hattori, western Iga.
During the fall of Iga to Nobunaga, Sandayu either perished or escaped and went into hiding.
Some other important kin groups which Iga units organized themselves around were the Kitakata-clan, Fukuchi-clan and Hioki-clan.
At the local level, individual villages formed ''dōmyōsō'' ("leagues of villages").

forms of
shugendō, a syncretism of
Shinto and
Buddhism – specifically,
Tendai and the
Shingon school of
Tantric Buddhism – was the prevalent religion.
The Buddha statues dating back to the
Heian period are still displayed in the present-day. The Fujibayashi clan worshipped at the Tejikara-jinja Shinto shrine.
Fujibayashi Nagato no Kami was known for his specialty in fire practices at the site, which are commemorated in the present-day with fireworks.
The Hattori clan was associated with Aekuni Shrine and is thought to have originated the Kurondo Matsuri in which participants dress entirely in black.
The ''Iga-shū'' sometimes facilitated important ceremonial events: The funeral of Shinsei, the founder of the Tendai sect Tendaishinsei-shu, in 1495 was mainly held by influential samurai from Iga, and in 1580 Iga ''jizamurai'' held a festival at
Aekuni Shrine, the
Ichinomiya for the Province, attended by Kanemi Yoshida, a priest from
Yoshida Shrine in Kyoto.
