The Baháʼí Faith is a world religion that was founded in the 19th century Middle East. Its founders and the majority of its early followers were of Iranian heritage, and it is widely regarded as the second-largest religion in Iran after Islam. Though most Baháʼís in Iran are of a Muslim background, the 19th century conversions of sizeable numbers of individuals from Judaism and Zoroastrianism in the country are also well documented.
The early history of the Baháʼí Faith in Iran covers the lives of these founders, their families, and their earliest prominent followers known by honorific designations such as the Letters of the Living and the Apostles of Baháʼu'lláh.
Since its inception the Baháʼí Faith has promoted democratically elected councils; the promotion of modern education as a priority within families (with emphasis on female education) and specific encouragement of women's equality with men. Iranian Baháʼís have created schools, agricultural cooperatives, and medical clinics across the country for themselves and others. Iran is also where the greatest persecution of Baháʼís has taken place—including the denial of education, arbitrary arrest, and killing. Iran's long history of state-sponsored persecution against Bábís and Baháʼís is well documented. The website "Archives of Baháʼí Persecution in Iran" has compiled thousands of documents, reports, testimonials, photos, and videos revealing proof of efforts to suppress and eliminate Baháʼís, particularly since the Iranian revolution of 1979.
From the nineteenth century onward, Bahá'ís in Iran sought to translate the teachings of Bahá'u'lláh and 'Abdu'l-Bahá into practical service that benefited not only their own community but also contributed to Iran's wider social development and modernization, despite recurring persecution and legal and social restrictions. Through elected consultative councils—later formalized as spiritual assemblies—they promoted collective decision-making, accountability, and broad participation, offering an alternative to both autocratic rule and clerical hierarchy while also shaping early approaches to constitutional and democratic ideas. Their initiatives addressed concrete needs such as education, health, and social welfare, including the establishment of modern schools and programs that expanded access to girls' education, public hygiene measures, vocational training, and charitable and economic enterprises that served the broader population. Iranian Bahá'ís also contributed significantly to the worldwide spread of the Faith through travel, pioneering, and participation in international teaching plans, providing volunteers and resources that helped establish and strengthen Bahá'í communities across the Middle East, Asia, Africa, Europe, and the Americas.
Origins and early years Central figures The Báb
Baháʼís trace the origin of their faith to 1844, when Siyyid 'Alí-Muhammad of Shiraz taught that he was a divine messenger with a mission to prepare for the imminent appearance of the "Promised One" of all religions. 'Alí-Muhammad was a direct descendant of Muhammad, born on 20 October 1819, and referred to himself as the "Báb", a religious title meaning "the Gate", indicating his position as a spiritual "gate to divine knowledge", and to a still greater God-sent educator whose imminent appearance he was preparing the way for. The bedrock of his theology was that a new era in human history had dawned, during which the oneness of all religions and their progressive nature as successive stages of guidance from the same Creator would become clear.
As the Báb's teachings spread thousands soon became followers. Islamic clergy began to stir up hostility towards the Báb and violence against his adherents (called Bábís). Insisting divine revelation had ended with Muhammad, Muslim clerics denounced the Báb's ideas as heretical, and also portrayed them as destabilizing for the best interests of the Shah of Persia. By manipulating support from fearful authorities, such clergy initiated a frenzy of persecution fueled by fanatical hatred rooted in religious prejudice. As killings began to spread around the country they ultimately resulted in wanton massacres of an estimated 20,000 Bábís. In a desperate bid to eradicate his faith, Persia's prime minister ordered the public execution of the Báb; it took place in Tabriz on 9 July 1850 before an estimated crowd of 10,000, in circumstances reported as miraculous by both Iranian eyewitnesses and foreign diplomats.Maj. Justin Sheil, British envoy to Persia, in his 22 July 1850 report to British Foreign Secretary Lord Palmerston, cited by Oppression against the faith in Iran has continued unabated ever since, up through the present day.
The Báb proclaimed he was the first of two "twin" manifestations of God sent by the Creator to prepare humanity for, and to usher in, its age of maturity when the human race as a whole will finally realize global unity. 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 next divine educator would appear soon after the Báb's own passing. 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."
Baháʼu'lláh
Husayn ʻAlí Núrí was one of the earliest and most active followers of the Báb. He first became known by the title "Baháʼu'lláh" (meaning "the Glory of God") among Bábís. Born on 12 November 1817 in Tehran, Baháʼu'lláh's father was a wealthy government minister who traced his ancestry to monarchs of the great Sasanian Empire. As the initial pogrom against Bábís spread across Iran, Baháʼu'lláh was spared due to his acknowledged public reputation for devoted service to the poor and the prestige of his family. However that ended when two disturbed youths, obsessed with the execution of the Báb which they blamed on the reigning monarch, attempted to assassinate Naser al-Din Shah on 15 August 1852. Though investigations showed the 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. Because of his prominence in support of the Bábí cause, Baháʼu'lláh was arrested and incarcerated in the notorious Síyáh-Chál of Tehran, where he was bound in heavy chains that left life-long scars. When Baháʼu'lláh did not quickly perish as had been expected, his food was poisoned—which impaired his health for years. Baháʼu'lláh was kept in 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. When it was proven beyond any doubt that Baháʼu'lláh was absolutely innocent of any wrongdoing, the Shah finally agreed to free him but decreed Baháʼu'lláh would be forever banished from Iran. Dispossessed of his extensive properties and wealth, in the exceptionally severe winter of January 1853 Baháʼu'lláh with family members undertook a three-month journey to Baghdad, thus beginning what became exile for the rest of his life in territories of the Ottoman Empire.
From Baghdad, Baháʼu'lláh dispatched communications and teachers to inspire and revive the persecuted followers of the Báb in Iran. In 1863, on the eve of departing for Constantinople (now Istanbul) at the invitation of Ottoman authorities, Baháʼu'lláh declared, to the many Bábís who had followed him to Iraq, that he was the Promised One foretold by the Bab—a revelation which had come to him in visions that mark the beginning of his mission in 1852 while chained in the dungeon of Tehran. Following malicious misrepresentations by the Persian ambassador to the Ottoman court, less than four months after arriving in Constantinople Baháʼu'lláh was banished by Sultan Abdulaziz to Adrianople (now Edirne); then in 1868 he was moved as an Ottoman prisoner to their penal colony in ʻAkká (now Acre, in modern Israel).
First in Constantinople, then in Adrianople and 'Akka, Baháʼu'lláh publicly proclaimed his mission as a messenger of God in missives directed to major religious and secular rulers of the time, including Czar Alexander II, Napoleon III, Pope Pius IX, and Queen Victoria. Throughout the remainder of Baháʼu'lláh's life most Bábís became his followers, and adherents became known as Baháʼís. Over the three decades in which Baháʼu'lláh revealed his teachings it became clear how they fulfilled and augmented the prophetic intent of the Báb in stating his message would become "a world religion centering on the principle of the oneness of humankind." Baháʼu'lláh's large body of writings, in both Persian and Arabic, are equivalent to more than 100 volumes. Currently translated into at least 800 languages, Baháʼu'lláh's writings form the foundation upon which the worldwide Baháʼí community now stands in virtually every country on earth.
Towards the end of his life, the strict harsh confinement ordered for Baháʼu'lláh was gradually relaxed by authorities in 'Akka who came to greatly admire him, and he was allowed to live in a home nearby, while still officially a prisoner of that city. Baháʼu'lláh passed in 1892, and his resting place at Bahjí is globally regarded by Baháʼís as a place of pilgrimage. At the time of Baháʼu'lláh's passing, the Baháʼí Faith had members in 13 countries of Asia and Africa. Under the leadership of his son ʻAbdu'l-Bahá, the faith gained a footing in Europe and America, and was further consolidated in Iran—though it continued all the while to suffer intense persecution there.
ʻAbdu'l-Bahá The eldest son of Baháʼu'lláh and his wife Navvab was born in Tehran on 23 May 1844, he was named 'Abbas after his paternal grandfather. Because Baháʼu'lláh commonly referred to him as "the Master", most Baháʼís used that term for him until Baháʼu'lláh's passing. After that, he was best known as ʻAbdu'l-Bahá, which means the "servant of Bahá"—a designation he requested Baháʼís use when referring to him, as a constant reminder of his servitude to Baháʼu'lláh and to his cause. In Baháʼu'lláh's written Will he directed all believers to faithfully turn to ʻAbdu'l-Bahá as Head of the Baháʼí Faith, as the Centre of the Covenant of Baháʼu'lláh, and as the sole authoritative Interpreter of his writings.
