The Báb (born ʻAlí-Muḥammad; /ˈæli moʊˈhæməd/; Persian: علیمحمد; 20 October 1819 – 9 July 1850) was an Iranian religious leader who founded Bábism, and is also one of the central figures of the Baháʼí Faith. The Báb gradually and progressively revealed his claim in his extensive writings to be a Manifestation of God, of a status as great as Moses, Jesus, and Muhammad, receiving revelations as profound as the Torah, Gospel, and Quran. This new revelation, he claimed, would release the creative energies and capacities necessary for the establishment of global unity and peace.
He referred to himself by the traditional Muslim title "Báb" (meaning the gate) although it was apparent from the context that he intended by this term a spiritual claim very different from any which had previously been associated with it. He proclaimed that the central purpose of his mission was to prepare for the coming of a spiritual luminary greater than himself — the promised one of the world's great religions; he referred to this promised deliverer as "he whom God will make manifest". The Báb was the "gateway" to this messianic figure, whose message would be carried throughout the world.
