Following the Nine-Tailed Demon Fox's Attack, Konohagakure's leadership began to suspect that the Uchiha were behind the attack due to the Sharingan's ability to control the beast. From that point onwards, the Uchiha were placed under close surveillance — something Tobi claims was accomplished by forcing all Uchiha to live in one section of the village. This mistrust and isolation from the rest of the village created feelings of ill-will amongst the Uchiha, and ultimately rekindled the hatred harboured towards the Senju-influenced government. As such, the Uchiha — led by Fugaku Uchiha — began planning a coup d'état to overthrow the Konoha leadership.
