The Báb was a 19th-century religious leader in Persia, known for founding the Bábí faith. Born as Siyyid `Ali Muhammad in 1819, he claimed to be a messenger of God and announced the coming of a new prophet. His teachings emphasized the unity of all religions and the importance of social justice. The Báb's movement attracted many followers, but it also faced severe persecution from the Persian authorities. In 1850, he was executed, but his teachings laid the groundwork for the later development of the Bahá'í Faith, which emerged under the leadership of Bahá'u'lláh, the Báb's successor.
