When does madara Uchiha die?

Answer 1

Madara was thought to have been killed while fighting the First Hokage, Hashirama Senju. But he survived, and retreated to plan revenge. He linked himself with the Gedou, the statue of the outer path, as a life support system. He also found himself a disciple, Obito Uchiha. When he'd taught Obito everything he needed to know, he disconnected himself from the statue and died. He intended for himself to be resurrected properly by Nagato, at the moment however he has been revived by the impure world resurrection jutsu.
