executed by firing squad in Tabriz at the age of 30. In his teachings the Báb identifies himself as the first of two Manifestations of God whom the Creator was sending to usher in the enduring peace that is to signify humanity’s attainment of maturity—when all people will live in unity as one human family. Baháʼís hold that the Báb's teachings lay the groundwork "for the eventual establishment of a society characterized by the unity of nations, fellowship of religions, equal rights of all people, and a compassionate, consultative, tolerant, democratic, moral world order". Woven throughout the Báb's teachings are references to "Him whom God shall make manifest", the great Promised One for whom he was preparing the way. In numerous prophesies the Báb stated that the next divine educator would appear shortly after his own expected martyrdom. In one of his major works, the Báb stated: "Well is it with him who fixeth his gaze upon the Order of Baháʼu'lláh, and rendereth thanks unto his Lord." Arrest and imprisonment Events leading up to and after the execution of the Báb were tumultuous for Bábís. As Muslim leaders incited fanatic mobs to violence against them, many Bábís—while refusing to take offensive steps against attackers—did take actions to defend themselves, but commonly ended-up being slaughtered. On 15 August 1852, two Bábí youth—in deep despair over the killings of the Báb and his leading disciples—made an ill-conceived attempt to assassinate the Iranian king whom they blamed for these tragedies. As Nasiri'd-Din Shah passed along a public road the two blocked the monarch to fire birdshot at him. The king escaped serious injury, but the incident led to an outburst of persecution against Bábís far exceeding past events. Though investigations found the offending pair acted alone, a "reign of terror" was unleashed, killing at least 10,000 Bábís that same year as government ministers vied with one another to collectively punish known or suspected Bábís, including Bahá’u’lláh. Well known for his support of the Bábí cause, Baháʼu'lláh was arrested and incarcerated in the subterranean Síyáh-Chál of Tehran, where he was bound in heavy chains that left life-long scars. Baháʼu'lláh was confined to that dungeon for four months, as the mother of the Shah and authorities seeking to curry favor with the king sought ways to justify executing him. Revelation During imprisonment in the Síyáh-Chál Bahá’u’lláh relates he had several mystical experiences in which he
