The Uchiha Clan (うちは一族, Uchiha Ichizoku) is one of the four noble clans of Konohagakure, reputed to be the village’s strongest because of their Sharingan and natural battle prowess. After helping found Konoha decades ago, the Uchiha grew increasingly isolated from the village’s affairs, culminating in most of their deaths during the Uchiha Clan Downfall. Few Uchiha now survive into the present day.

The Uchiha are descendants of Indra Ōtsutsuki, the elder son of Hagoromo Ōtsutsuki. Through Indra, the Uchiha inherited Hagoromo’s “eyes”, granting them powerful spiritual energy and chakra. As part of the so-called “Curse of Hatred” first displayed by Indra, Uchiha are subject to powerful emotions: these emotions typically start as love for a friend or family member that then become overpowering hatred when the object of their love is lost. This loss, whether actually experienced or merely threatened, awakens an Uchiha’s Sharingan. It is due to the Sharingan that the Uchiha have received much of their fame and notoriety.
