October 20th is Birth of the Báb

Siyyid `Alí Muḥammad Shírází (/ˈseɪ.jədˈæ.liː.moʊˈhæ.məd.ʃiˈrɑːzi/, Persian: سيد علی ‌محمد شیرازی‎‎; October 20, 1819 – July 9, 1850) was the founder of Bábism, and one of three central figures of the Bahá'í Faith. He was a merchant from Shiraz, Persia who, at the age of twenty-four (on the evening of May 22, 1844), claimed to be an inspired interpreter of the Qur'an within the Shaykhi school of Twelver Shi'ism. He made bolder claims as time passed, and in 1847, during a trial in Tabriz, asserted a claim to be the Shi'i 'promised one' or Qá'im (or Mahdi). After his declaration he took the title of Báb (/ˈbɑːb/, Arabic: باب‎) meaning "Gate" or "Door". He composed numerous letters and books in which he stated his messianic claims and defined his teachings, which constituted a new sharí'ah or religious law. His movement eventually acquired thousands of supporters, was opposed by Iran's Shi'i clergy, and was suppressed by the Iranian government, leading to the persecution and killing of between two and three thousand of his followers, called Bábís. In 1850, at the age of thirty, the Báb was shot by a firing squad in Tabriz.

Bahá'ís claim that the Báb was also the spiritual return of Elijah and John the Baptist, that he was the saoshyant referred to in the Zoroastrian scriptures, and that he was the forerunner of their own religion. Bahá'u'lláh, the founder of the Bahá'í Faith, was a follower of the Báb and claimed to be the fulfillment of his promise that God would send another messenger.
