The Báb was the founder of Bábi Faith, and one of the central figures of the Baháʼí Faith. He was a merchant from Shiraz in Qajar Iran who, in 1844 at the age of 25, began the Bábi Faith. In the next six years, he 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.

Zoroaster, also known as Zarathustra, was a religious reformer and the spiritual founder of Zoroastrianism. In the second millennium BC he founded the first documented monotheistic religion in the world and also had an impact on Heraclitus, Plato, Pythagoras, and the Abrahamic religions, including Judaism, Christianity, and Islam. Zoroastrians believe that he was a prophet who transmitted God's messages and founded a religious movement that challenged the existing traditions of ancient Iranian religion, while in the minority Ahmadiyya branch of Islam and in the Baháʼí Faith, he is also considered a prophet. He was a native speaker of Avestan and lived in the eastern part of the Iranian plateau, but his exact birthplace is uncertain.
