The Báb's declaration of His station was made in the city of Shiraz in what is now Iran. He almost immediately attracted a large following, which governmental and religious authorities found threatening. Some 20,000 of His followers were killed, and the Báb Himself was executed by firing squad in 1850 in the northern Iranian city of Tabriz.
His remains are entombed in Haifa, Israel, in a beautiful, golden-domed shrine surrounded by gardens on the side of Mount Carmel. The house in Shiraz, Iran, where the Báb first made His announcement, had been preserved as a Baha'i holy site, but in 1979, it was destroyed by a mob aided by revolutionary guards.
The Bahá'í calendar dates from 1844, with the year 169 B.E. (Bahá'í era) now under way. The Declaration of the Báb is one of nine holy days during the year on which Bahá'ís suspend work. For the people who are now Bahá'ís, it was the birth of their religion. Bahá'í communities around the world celebrate the anniversary with special devotional programs and gatherings on the evening of May 22. Believers suspend work, and children and youth take off from school.
