History

Warring States Period

Before the hidden-village system, shinobi operated as mercenary clans hired to fight one another. The Senju and Uchiha were the two strongest clans, and the practice of opposing clients hiring each against the other turned them into hereditary enemies. 31

Hashirama Senju and Uchiha Madara ended this pattern by uniting their clans, sweeping through the Warring States Period, and establishing the “one country, one village” system. Konohagakure was the first product of this order. 31

Despite the village system, the great nations continued to fight through proxy battlefields. Smaller countries such as the Land of Hot Water, Land of Fields, and Land of Rain were repeatedly used to keep war away from the great nations’ homelands. 43 54

Uchiha Mirai's Reforms and Unification

During and after the Third Shinobi World War, Uchiha Mirai restored the Uchiha Clan’s standing, defeated major rival leaders, overthrew Hiruzen Sarutobi and Danzō Shimura, and reformed Konohagakure. His reforms elevated ninja from tools of the nobility to a class above royalty and aristocracy. 162

Mirai publicly argued that separate nations, unequal resources, and national barriers made lasting peace impossible. He proposed the Great Unification plan: a single empire that would centrally allocate resources across the Shinobi World. 163

After the Lands of Fire, Wind, Water, Lightning, and Earth submitted to him, Mirai established the Divine Nation. He became its Emperor, while the Five Kage retained authority as regional administrators. 190 240

The Land of Iron was destroyed after resisting Divine Nation expansion, ending the samurai’s place as an independent political force in the Shinobi World. 197

Interstellar Era

The Divine Nation eventually expanded across the entire Shinobi World, ending large-scale ninja warfare and transforming the world into a modernized society. 272

When the Ōtsutsuki Clan attacked, Uchiha Mirai led a ten-thousand-man Divine Nation Ninja Army through spatial portals to the clan’s homeworld. The campaign culminated in Mirai’s pursuit and destruction of Ōtsutsuki Shibai, as well as the annihilation of the Ōtsutsuki Clan. 335 336 338 340

After the war, Mirai repaired the damaged cosmic space and dispatched a Vanguard Army to explore the universe. The Shinobi World became the main base and sacred land of an expanding human civilization. 340 344

Chakra and Ancient Origins

Origin of Chakra

Chakra originated with Kaguya Ōtsutsuki rather than Hagoromo Ōtsutsuki, the Sage of Six Paths. Hagoromo later founded the Ninja Sect and spread chakra among its followers, creating the foundation of shinobi society. 191 192

Kaguya and Isshiki Ōtsutsuki arrived from another planet and planted the Divine Tree. Kaguya consumed its fruit, while the Divine Tree later transformed into the Ten-Tails during her conflict with Hagoromo and Hamura. 190 192

Hagoromo became the first jinchūriki by sealing the Ten-Tails within himself. Before his death, he divided its chakra into the nine Tailed Beasts and sealed the Ten-Tails’ husk on the moon. 185 192

Bloodlines and Historical Conflict

The Hyuga Clan descends from Hamura Ōtsutsuki. 192

The Uchiha Clan descends from Indra, Hagoromo’s elder son, while the Senju Clan descends from Asura, his younger son. The Uzumaki and Kaguya Clans also carry these bloodlines to varying degrees. 254

Black Zetsu manipulated conflicts among shinobi clans for generations in an effort to revive Kaguya through the Infinite Tsukuyomi. 254

Natural Energy Cultivation

Before Kaguya’s arrival, powerful creatures in the Shinobi World cultivated Natural Energy rather than chakra. Their pursuit centered on immortality and enlightenment, and the strongest surviving traditions became the Three Great Sage Lands. 341

Mount Myōboku, Ryūchi Cave, and Snake Forest survived because they existed in separate dimensions. After the Ōtsutsuki Clan’s defeat, Uchiha Mirai permitted the Sages to reopen their inheritances and move freely throughout the Shinobi World. 341

Society and Development

Universal Ninja Training

Historically, ninjutsu and secret techniques were expensive, restricted resources passed through clans, disciples, or official exchanges. 197

Uchiha Mirai ordered the Chakra Refining Method and Natural Mental Power Cultivation Method distributed throughout the Shinobi World, allowing ordinary people to develop chakra and mental power. 197 198

• Chakra is formed from physical energy and mental power. 196
• The cultivation methods improved the number and quality of shinobi across the Divine Nation. 198
• Ordinary citizens received access to chakra refinement and mental cultivation, though not necessarily to combat techniques or secret arts. 304

Chakra Collection System

Uchiha Mirai used Imprinted Tsukuyomi and Yachihoko to place marks on chakra users across the Shinobi World. The marks collect part of each user’s chakra, which is then stored for the artificial creation of Six Paths-level shinobi. 301

• The initial collection drew roughly one-third of the chakra from users across the world without lasting bodily harm. 301
• Nearly one million chakra users could provide chakra comparable to a complete Nine-Tails every three days. 301
• A decade later, approximately ten million people could refine chakra, allowing Mirai to collect chakra equivalent to a Ten-Tails in a single day if necessary. 304

Technology and Infrastructure

The Divine Nation developed extensive infrastructure and scientific ninja technology under Uchiha Mirai’s rule. 228 239

• Transportation — Trams, rail lines, cars, ships, and airplanes became widespread. 228 239 304
• Information technology — Research expanded into computers, software, games, and online video. 228 237 304
• Scientific Ninja Tools — Chakra-storage materials, chakra armor, and related equipment reshaped ninja combat and enabled the mass-production plan for Six Paths-level powerhouses. 300
• Interplanetary development — Intelligent puppets mine resources on multiple planets and return materials for chakra storage, energy refinement, and treasure production. 334

Major Threats

• Ōtsutsuki Clan — Extraterrestrial beings whose pursuit of Chakra Fruits and planetary energy placed the Shinobi World at risk of extinction. 190 334
• Kara Organization — An organization connected to Isshiki Ōtsutsuki that infiltrated smaller countries, spread a religion in the Land of Snow, and pursued biological and technological power. 319 320 324
• Black Zetsu — Kaguya’s will, which manipulated shinobi history to restore her through the Infinite Tsukuyomi. 254
• Mōryō — An immortal destructive monster whose release threatened the Land of Demons and the wider Shinobi World. 277 278
• The Ōtsutsuki invasion — The final large-scale external threat, ended when Uchiha Mirai defeated Ōtsutsuki Shibai and destroyed the clan. 338 340

Trivia

• The Shinobi World’s former political order treated ninjas as low-status tools, while the Divine Nation elevated them above the traditional nobility. 130 162
• The Nine Tailed Beasts are fragments of the Ten-Tails’ chakra rather than separate primordial creatures. 185 192
• The Dragon Vein originated from the power of an ancient human from the Land of Rou’s royal lineage, who transformed his energy into the underground Dragon Vein before death. 341
