The Third Shinobi World War (第三次忍界大戦, Daisanji Ninkai Taisen) is the third of the four shinobi wars that involved the majority of the shinobi villages. It takes place more than ten years prior to the beginning of the series and has been rarely shown in the series outside the Kakashi Gaiden. Because of a decline in national power, the reign of the Five Great Countries was crumbling. Along their borders, skirmishes with smaller nations broke out all the time. The prolonged war gradually spread its fires far and wide, until at last it developed into the Third Shinobi World War. This war turned into an unprecedented war of attrition, tormenting all nations with a shortage of war potential. Not even excluding a great power like Konoha, very young children, some of whom were barely out of the Academy were thrown unto the battlefield, eventually losing their short lives during the war.

War

Konohagakure and Iwagakure fought across Kusagakure after the latter had infiltrated it in order to lay siege to the border of the Land of Fire. It was not until the destruction of the Kannabi Bridge that the war began turning in Konoha's favour. Iwagakure was also known to have been fighting Kumogakure with various skirmishes between the two villages. Sunagakure also participated in the war. Kumogakure was also seemingly a part of this war, with at least Konohagakure clashing with shinobi from this village, specifically Minato and A. These two villages finally made peace after the Hyūga Affair. This is also the war in which Third Raikage died and where the Fourth Raikage was appointed. Kirigakure also partook in the war against Konohagakure and made Rin Nohara into the jinchūriki of the Three-Tails. Rin then chose to die by Kakashi's hands, rather than being used as a tool to destroy her own village. The shinobi were adamant in retrieving Rin's body and not allowing it to fall into enemy hands at all costs. They were however stopped by a grief-fuelled Obito Uchiha who unbeknownst to his team-mates had actually survived the landslide that had supposedly killed him with Obito mercilessly slaughtering all the shinobi in sight. Some time after this, Madara Uchiha would pass away, but not before passing his plans onto Obito to fulfil until the time of his resurrection. Ao from Kirigakure also defeated a member of the Hyūga clan and took the member's Byakugan for his own right eye socket. In the anime, both Third Tsuchikage and Third Hokage had grown weary of sacrificing more lives to ongoing stalemate and finalised a peace treaty over the objection of war hawks in their respective villages. However, Ōnoki was more relunctant to accept the peace treaty, only accepting it after Minato single-handedly stopped an invasion consisting of a thousand Iwa shinobi.

Effects

Minato Namikaze was a key factor in Konoha winning the war, gaining the moniker of Konoha's Yellow Flash (木ノ葉の黄色い閃光, Konoha no Kiiroi Senkō) and being named Konoha's Fourth Hokage (四代目火影, Yondaime Hokage; Literally meaning "Fourth Fire Shadow") at the war's conclusion. Kakashi Hatake, Minato's student, gained a Sharingan in his left eye from his team-mate, Obito Uchiha during the mission to destroy the Kannabi Bridge. He would go on to become renown as Copy Ninja Kakashi (コピー忍者のカカシ, Kopī Ninja no Kakashi). Itachi Uchiha was traumatised by the violence of the war and grew to seek peace at any cost because of it: an experience that would shape the rest of his life.

Sasori earned fame as Sasori of the Red Sand (赤砂のサソリ, Akasuna no Sasori), due to his ingenious puppets dyeing the sand red with his enemies' blood. At some point however, Sasori left the village after secretly turning the Third Kazekage into one of his human puppets, leading to the appointment of the Fourth Kazekage after a long but futile search for the Third by Sunagakure. The Battle of Kikyō Pass, where Kabuto Yakushi was said to have been found orphaned (although this was later revealed to be a cover), took place in this war.

In Amegakure, Yahiko, Nagato, Konan, and many other shinobi formed a group that eventually fought the rule of Hanzō. Initially, they were merely preaching peace for Amegakure. They were supported and even invited to negotiate peace by Hanzō himself. In the anime, they unknowingly disrupted Danzō's attempt to disrupt a ceasefire between Konohagakure and Iwagakure. After Danzō used his men's corpses to frame Akatsuki of murdering his village's shinobi, Hanzō came to fear that they were power hungry and would usurp his power. He betrayed them and called in the assistance of Danzō and his Root Anbu while holding Konan hostage. The confrontation between the two sides led to Yahiko committing suicide, choosing to do so for the sake of Nagato. Left devastated, Nagato responded by summoning the Demonic Statue of the Outer Path which slaughtered all of the Amegakure and Root shinobi who had been instructed to kill Nagato. Nagato also attempted to kill Hanzō who fled. This incident failed to suppress the group and led to a civil war with Nagato becoming the new leader of Akatsuki. The resulting civil war split Amegakure and ultimately resulted in the complete and utter annihilation of Hanzō's faction with Hanzō himself eventually dying at the hands of Pain/Yahiko.

In Kirigakure, Ao gained a Byakugan as a spoil of war from a Hyūga clan member he defeated. This allowed him to see through the hypnosis that controlled the Fourth Mizukage.

Furthermore, Hiruzen decided to step down as Hokage while letting Minato rule in his steed instead of listening to Danzō and promoting Orochimaru.
