did not recognize Baháʼu'lláh, Subh-i-Azal remained their leader until his death in 1912, and Azali successorship remains disputed. Baháʼí sources report that 11 of the 18 "witnesses" appointed by Subh-i-Azal to oversee the Bábí community became Baháʼís, as his son did. The man allegedly appointed by Subh-i-Azal to succeed him, Hadíy-i-Dawlat-Abádí, later publicly recanted his faith in the Báb and Subh-i-Azal. Baháʼu'llah emerged more successful and nearly all of the Báb's followers abandoned Subh-i-Azal and became Baháʼís. Today Baháʼís have several million followers, while estimates of the number of Azalís are generally around one thousand in Iran, and any organization of theirs seems to have ceased to exist. Commemorations in the Baháʼí Faith In the Baháʼí calendar the events of the birth, declaration and death of the Báb are commemorated by Baháʼí communities on a yearly basis. At the centennial of the declaration of the Báb to Mulla Husayn in May 1944, the Baháʼís had a viewing of the portrait of the Báb during the celebrations held at the Baháʼí House of Worship (Wilmette, Illinois). Speaking at the event were Dorothy Beecher Baker, Horace Holley, and others. The notion of "twin Manifestations of God" is a concept fundamental to Baháʼí belief, describing the relationship between the Báb and Baháʼu'lláh. Both are considered Manifestations of God in their own right, having each founded separate religions (Bábism and the Baháʼí Faith) and revealed their own holy scriptures. To Baháʼís, however, the missions of the Báb and Baháʼu'lláh are inextricably linked: The Báb's mission was to prepare the way for the coming of Him whom God shall make manifest, who eventually appeared in the person of Baháʼu'lláh. Both the Báb and Baháʼu'lláh are revered as central figures of the Baháʼí Faith. A parallel is made between Baháʼu'lláh and the Báb as between Jesus and John the Baptist. Impact Abdu'l Baha summarises the Báb's impact: "Alone, He undertook a task that can scarcely be conceived... This illustrious Being arose with such power as to shake the foundations of the religious laws, customs, manners, morals, and habits of Persia, and instituted a new law, faith, and rel igion." He has been to compared to Martin Luther The Bábí movement had a major impact on religious and social thought in 19th century Iran. Christopher de Bellaigue, writing about the Enlightenment period in the Islamic world, wrote, Writings The Báb affirms that the verses revealed by a
