He went to the East in his youth and returned convinced that he was the Mahdi and that he was destined to reform Islam. He was a rigorist and purist in doctrine and morality. Believing in a mystical concept of the oneness of God, Ibn Tumart fought violently the anthropomorphism then current. He became increasingly fanatical, until he finally preached a holy war against Muslims who disagreed with him. He was esteemed as a man of compelling personality and of great sagacity.
