Declaration of the Báb
The Declaration of the Báb, occurring on May 23, 1844, in Shiraz, Persia, marks the moment Siyyid ‘Alí-Muhammad announced He was a Messenger of God and the Herald of a new era, specifically to prepare the way for Bahá'u'lláh. This event launched the Bábí Faith and is celebrated as one of nine holy days in the Bahá'í calendar.
