**Spoilers ahead!**

> When Black Zetsu impaled Madara, he transfered Kaguya's will into Madara. By
> this process, Kaguya was revived by using Madara's body as the host vessel.
> And yes, it was planned from beginning by Zetsu.

Black Zetsu's history:

> He was created by Kaguya and served only her. He acted as if he was Madara's
> creation, so he could facilitate the revival of his "mother", aka Kaguya. To
> do this, he planned the activation of Infinite Tsukuyomi by influencing
> Madara and the Akatsuki.
