The Báb's declaration and the birth of Bábism
A Shiraz merchant calls himself the “Gate” — Baháʼí roots

On 23 May 1844 the young merchant Sayyid ʻAlí Muhammad declared himself the Báb, the “Gate” to the hidden imam. His movement spread fast across Iran and was harshly suppressed; the Báb himself was executed by firing squad in Tabriz in 1850. His follower Baháʼu'lláh, in Baghdad in 1863, founded a new religion — the Baháʼí Faith.
