On the evening of May 22, Baha'is throughout the world commemorate the Declaration of the Bab, which took place in this room (pictured) in the Persian city of Shiraz in 1844.

"His life is one of the most magnificent examples of courage which it has been the privilege of mankind to behold,” French writer A.L.M. Nicolas said of the Báb (“gate” in Arabic).

The Báb—born Siyyid `Alí-Muhammad in Shiraz, Persia (now Iran)—announced on May 22, 1844, that He was the bearer of a Divine Revelation which would prepare humanity for the advent of the Promised One of all religions.
