Akatsuki

Akatsuki was originally founded by Yahiko during the Third Great Shinobi World War and consisted of Amegakure ninja that wished to create peace for their home country, which acted as a battleground for three of the Five Great Shinobi Countries. Yahiko insisted that his and the rest of Akatsuki's actions were meant only to aid Nagato in bringing world peace, though Konan claimed that it was Yahiko's charisma that held the group together and spurred them on. Madara Uchiha alleges that it was his encouragement which lead to Yahiko forming the organization, and thus credits himself as the group's creator.

In its early days, Akatsuki gained fame and recognition in Amegakure, drawing the attention of Hanzō, a world-renowned ninja and leader of the country. Hanzō, believing that the group was becoming a threat to his rule, approached the organization and falsely claimed that he wanted to use them as the axis to negotiate peace between Konohagakure, Iwagakure, and Sunagakure. However, Hanzō betrayed Akatsuki and, working together with Danzō Shimura of Konohagakure's ANBU, kidnapped Konan and orchestrated Yahiko's death. After synchronizing with the Demonic Statue of the Outer Path and attempted to exact revenge on Yahiko's killers, Nagato inherited leadership of the organization and prompted a civil war, eventually killing Hanzō and gaining victory and control of Amegakure.

Following the Third Great Shinobi World War, Akatsuki became a mercenary group for hire and Nagato presumably began taking direction from Madara, who acted as the organization's collaborator and benefactor. In times of peace most of the ninja villages, rather than increasing their own armaments, employed Akatsuki to fight in wars, spy on enemies, or carry out assassinations. The Fourth Raikage claims that only Kumogakure has never used Akatsuki's services, and during this time it became widely believed that Akatsuki was founded and based in Kirigakure, perhaps due to Madara's influence over the Fourth Mizukage. Eventually, Akatsuki would begin capturing the tailed beasts, in the process antagonizing many of its former clients.

Events relating to Akatsuki before the start of Part II have only been given in pieces. Sasori and Orochimaru were partners for a time and were apparently very effective. Kakuzu had a number of partners that he killed in fits of rage. For this reason he was partnered with Hidan shortly before the start of Part II, Hidan's immortality meaning there would not need to be constant replacements. Itachi Uchiha apparently joined before carrying out the Uchiha clan massacre for which he defected from Konohagakure, though his membership seems to have come with the stipulation that Akatsuki could make no direct movements against Konoha. When Itachi joined, Orochimaru attempted to steal his body in order to gain the Sharingan. This failed and he was forced to defect. Deidara was recruited to replace Orochimaru as Sasori's partner, but because Orochimaru took his Akatsuki ring with him he could not also replace Orochimaru's position. Akatsuki also captured two tailed beasts before Part II, which in the anime are indicated to have been the Five-Tails and the Seven-Tails.

Akatsuki becomes much more active in Part II. At its start they assault Sunagakure to capture the One-Tail, but Sasori is killed. Madara, disguised as "Tobi", replaces him. Next are the Two-Tails and Three-Tails, though Hidan and Kakuzu are lost during an unrelated scuffle with Konoha ninja. After obtaining the Four-Tails, Deidara dies during his fight with Sasuke Uchiha, who soon afterwards causes Itachi's death too. Madara soon afterwards convinces Sasuke to work with Akatsuki. Although Akatsuki lost five members at this point, Madara claims it was worth it in order to gain Sasuke's loyalty. Despite this, their diminished numbers force Akatsuki to become more drastic in their efforts.

In the anime, Nagato goes to capture the Six-Tails (the beast having been caught at some earlier point in the manga). He and Konan are then sent to Konoha to capture the Nine-Tails. Konoha is destroyed, but they fail in their assignment; Nagato dying and Konan leaving the organization. At the same time, Sasuke and his team are tasked with capturing the Eight-Tails, but they too fail to complete the assignment. Akatsuki's actions finally provoke a response from the ninja villages, who hold a Kage Summit to discuss what should be done. Madara, wishing to accelerate his plans, infiltrates the meeting and declares war against the great nations, promising to use the seven tailed beasts Akatsuki has already captured as weapons. The villages and their associated countries form a Shinobi Alliance to combat Akatsuki, beginning the Fourth Great Shinobi World War.

In preparation for the war, Kisame Hoshigaki infiltrates Kumogakure to gather intel on the Shinobi Alliance, as well as to learn the location of the two remaining tailed beasts. He dies in the process, but not before sending what he has learned to Madara. Madara, meanwhile, goes to Amegakure to retrieve Nagato's body and the Rinnegan, as well as kill Konan. Kabuto Yakushi, a new ally of the organization, then captures Yamato, allowing him to strengthen an army of 100,000 white Zetsus.^[1] After Kabuto uses Summoning: Impure World Resurrection to supplement Akatsuki's numbers with ninja famous during their lives, Akatsuki marches off for war.
