A/N: I DO NOT OWN HARRY POTTER, THAT GOES TO J.K ROWLING, I DO NOT OWN NARUTO EITHER, AS THAT GOES TO KISHIMOTO. THE ONLY THING THAT I OWN ARE MY OC, MY MADE UP JUTSUS, THE PLOT AND HER CLAN INFORMATION.
During the Warring States Period, ninja were organised into small mercenary clans that knew nothing but battle. The two strongest of these clans were the Senju and the Uchiha, who had warred against each other for their entire histories. Eventually, intending to end the constant bloodshed, Hashirama Senju used his position as leader of his clan to broker a truce with the Uchiha clan through their leader, Madara Uchiha his childhood friend . Thus the Senju, the Uchiha, and their respective affiliated clans formed the first shinobi village: Konohagakure—a name invented by Madara himself. Other villages would soon start forming, following Konoha's example and essentially ending the Warring States Period.
Konoha as it appeared shortly after its founding.
Hashirama used his Wood Release abilities to produce much of the village's infrastructure. This ability and his ideals were two of the reasons he was chosen to become the village's leader: the Hokage. Madara, however, feared that the Senju would oppress his clan and attempted to gather support to overthrow Hashirama. No Uchiha would help, forcing him to take on Hashirama by himself. Madara was ultimately defeated at what would be called the Valley Of The End and he was believed to have died. As a result of the battle, Konoha came into possession of the Nine-Tails. To contain its enormous power, the village began its trend of sealing the beast within the Uzumaki, a clan that the Senju and thus the rest of Konoha had close ties with.
At some point, Hashirama came to bind most Tailed Beasts of the Land and sold them to other villages during the First Shinobi World War, to promote peace and tranquility. However, this peace was short-lived. Hashirama died during the war, shortly after the village began to flourish, and the mantle of Hokage was passed onto his brother, Tobirama Senju, who became the Second Hokage. Tobirama would later be killed by during the same war, but appointed as Third Hokage shortly before his death. Years later, during the Second Shinobi World War, Hiruzen led Konoha's forces against Iwa and Suna, using Amegakure as their battleground. Ame's leader, Hanzo, also fought Konoha a number of times, and during one of these battles gave Hiruzen's students - Jiraiya, Tsunade, Ichika, Orochimaru and - the title of Shinnin. During the Third Shinobi World War, Konoha fought the ninja of Iwagakure across Kusagakure. Konoha was almost defeated, but Minato Namikaze and his team helped turn the war back in their favor.
After the end of the Third Shinobi World War, Hiruzen chose Minato to replace him as Yondaime Hokage. Soon after Minato took office, however, a Masked Man kidnapped Minato's wife, the current Nine-Tails Jinchuuriki, Kushina Uzumaki after she had given birth to their son Naruto Uzumaki and removed it from her body, which he then used to attack Konoha. Minato was able to defeat the man, but the Nine-Tails proved more difficult. Left with few options, Minato and Kushina gave their lives to seal the Nine-Tails into the body of their newborn son. Many ninja died defending the village, and most survivors blamed Naruto for the Nine-Tails' actions. Hiruzen, Hokage again, outlawed all mention of the Nine-Tails so that future generations would not hate Naruto as their parents did.
The Hyūga Affair (日向の件, Hyūga no Ken)—as the incident is known nowadays in Kumogakure — happened nine years prior to the start of the series, while Kumogakure and Konohagakure were at war. In an attempt to put an end to the fighting, they agreed to a peace treaty to be signed on the date which coincided with Hinata Hyūga's third birthday. The treaty was soon revealed to might be nothing more than a cover when the person who was the Head Ninja Of Kumogakure at the time—who was in Konoha to sign the treaty—attempted to kidnap Hinata in order to obtain the Byakugan and its secrets. The shinobi was killed in his attempt by Hinata's father, Hiashi Hyūga.
Konoha's leadership believed an Uchiha was responsible for the Nine-Tailed Demon Fox's attack, and as such cut off the Uchiha from much of the village's affairs. Angered by this mistreatment, many of the Uchiha began plotting a coup d'état that would wrest control of Konoha. However, some Uchiha saw the dangers from such a venture. One such figure was Itachi Uchiha, who became a spy for Konoha's leadership. After peace talks failed, Danzo Shimura ordered Itachi to wipe out his clan in exchange for being allowed to spare his younger brother, Sasuke Uchiha. Itachi, with assistance from , did as instructed, but staged events to seem as though he acted alone and for selfish purposes so that Sasuke would someday take vengeance against him for what he did to their family.
Konoha is the site of the Chuunin Exams. During the exams' final stage the village is invaded by Otogakure and Sunagakure ninja, an attempt to end the peace and prosperity that Konoha alone has enjoyed since the Third Shinobi World War. The invaders are repelled, but Konoha suffers heavy casualties, including Hiruzen. Although Tsunade quickly replaces him as Fifth Hokage, recovery for the rest of Konoha's military forces is slow. The village is understaffed, leaving it unable to properly respond to events occurring in the interim such as Sasuke Uchiha's defection.
More than three years after the failed Konoha Crush, the Six Paths of Pein of Akatsuki attack Konoha in an effort to capture Naruto. Konoha's forces have some success while fighting the Peins individually, but can do nothing to stop the village's destruction by Pein's Shinra Tensei. Naruto returns to Konoha shortly afterwards and defeats Pein before confronting Nagato Uzumaki, the man behind Pein. After Naruto convinces him that his actions were wrong, Nagato gives his life to revive everyone that died during the invasion. Tsunade is left in a coma from exhausting herself in protecting Konoha from Pain, causing Danzo Shimura to temporarily take office as her replacement. Danzō oversees the start of the village's lengthy rebuilding process and deals with the immediate aftermath of Pein's attack. The villagers decided to rebuilt their village in the same place instead of a new area as they felt Konoha is where the Hokage Rock is.
Because of Akatsuki's growing aggression, the ninja villages decide to form Allied Shinobi Forces an to oppose Akatsuki in the Fourth Shinobi World War. Danzō is killed shortly after the Alliance is agreed upon, but Tsunade wakes from her coma in time to start overseeing the war efforts. Despite still being under construction, Konoha is used as a haven for refugees fleeing countries where much of the fighting is expected to take place. By the time the war is won, most of the village has been restored. As a result of the war, Konoha's population suffered greatly, but it gradually recovered.
Hermione closed the book she found in the library taking all the information in. Ninjas? Kunoichi? WARS?! It was all too much to take in, she wanted to learn more. Looking at the author of the book she saw one Nakano Nakamura. Maybe she should ask the Librarian for more books by this woman, at least she's assuming that she's a female, seeing that the name is a bit feminine in her eyes. Hermione put the book away and went to the Gryffindor dorm rooms seeing as it was close to curfew. She closed her eyes and went to sleep.
 'San' means 'Three', 'Shin' means 'Four'
