|Known Members:||Uchiha Clan Ancestor|
The Uchiha Clan descended from the elder of the two sons entrusted by the Sage of the Six Paths with his power and will. When it came time for the Sage to choose a successor, he questioned the two on what course of action they would follow to bring order to the world. The elder believed that might was the way to bring peace, while the younger believed love was the way. The Sage favored the ideal of the younger brother, and therefore designated the younger as his successor, causing the elder to be filled with jealously and hatefulness. From the younger son descended the Senju Clan who would be the eternal rivals of the Uchiha.
Before the Founding of the Hidden Villages
Before the founding of the ninja villages, the Uchiha were one of the mercenary clans for hire. Because of their Sharingan, the Uchiha Clan came to be known as one of the two strongest clans, the second being the Senju Clan. Madara Uchiha was particularly powerful, and, upon attaining the Mangekyo Sharingan, he took control of the clan. Under his leadership the Uchiha grew stronger, conquering whatever clans they came upon, such that, whenever the Uchiha Clan was hire for a job, the opposing side would hire the Senju Clan. Senju Kalamu was a one of the strongest in the clan and aided in many of thier victories.
The Senju Clan, grew tired of the endless fighting, and approached the Uchiha clan with a peace treaty. Madara feared that an alliance would lead the Uchiha to ruin, but his clan disagreed, and he was forced to accept. The two clans came together to form Konoha, with Hashirama Senju, leader of the Senju Clan, being selected as Hokage. Madara believed that this was proof that the Uchiha would be made subservient to the Senju, but his clan saw this only as his attempt to rekindle the flames of war. They turned their backs on him, and he defected. Following Madara's betrayal, the Second Hokage gave the Uchiha control of the Leaf Police Force as a sign of trust. According to Madara, this was really just a way of keeping the Uchiha in check and out of Konoha's governing affairs. Over the years, some Uchiha, such as Setsuna, have figured out this motive's true meaning, and tried to rebel against the village as Madara did, but they found that it was too late to make a difference, as the Senju had already completely suppressed the Uchiha.
Years later, after the Nine-Tails' Attack on Konoha, Konoha began to suspect that an Uchiha was behind the attack. Madara claimed that the Uchiha were relocated to a corner of the village so that they could be more easily monitored. The Uchiha interpreted this as confirmation of what Madara had warned them of years earlier, and began to plan overthrowing the village. One Uchiha, Itachi, disagreed with the coup d'état, and informed Konoha's leadership of what the Uchiha were up to. The Third Hokage, Hiruzen Sarutobi, tried to negotiate for a more peaceful approach. This failed, and to prevent an uprising that would create another war, Itachi was ordered to wipe out the Uchiha. Itachi spared only one Uchiha: his younger brother, Sasuke and their baby sister. Sasuke would spend the next few years trying to avenge their family by killing Itachi, something Itachi had planned for from the very beginning.
