The Bahá'í Faith (aɪ/; Persian: بهائی Bahā'i) is a religion teaching the essential worth of all religions, and the unity and equality of all people. Established by Bahá'u'lláh in 1863, it initially grew in Iran and parts of the Middle East, where it has faced ongoing persecution since its inception. Currently it has between 5 and 7 million adherents, known as Bahá'ís, spread out into most of the world's countries and territories.[note 1]
It grew from the mid-19th-century Bábí religion, whose founder taught that God would soon send a prophet in the same way of Jesus or Muhammad. In 1863, after being banished from his native Iran, Bahá'u'lláh announced that he was this prophet. He was further exiled, spending over a decade in the prison city of Akka in OttomanPalestine. Following Bahá'u'lláh's death in 1892, leadership of the religion fell to his son `Abdu'l-Bahá (1844–1921), and later his great-grandson Shoghi Effendi (1897–1957). Bahá'ís around the world annually elect local, regional, and national Spiritual Assemblies that govern the affairs of the religion, and every five years the members of all National Spiritual Assemblies elect the Universal House of Justice, the nine-member supreme governing institution of the worldwide Bahá'í community, which sits in Haifa, Israel, near the Shrine of the Báb.
Bahá'í teachings are in some ways similar to other monotheistic faiths: God is considered single and all-powerful. However, Bahá'u'lláh taught that religion is orderly and progressively revealed by one God through Manifestations of God who are the founders of major world religions throughout history; Buddha, Jesus, and Muhammad being the most recent in the period before the Báb and Bahá'u'lláh. Bahá'ís regard the major religions as fundamentally unified in purpose, though varied in social practices and interpretations. There is a similar emphasis on the unity of all people, openly rejecting notions of racism and nationalism. At the heart of Bahá'í teachings is the goal of a unified world order that ensures the prosperity of all nations, races, creeds, and classes.
In English-language use, the word Bahá'í is used either as an adjective to refer to the Bahá'í Faith or as a term for a follower of Bahá'u'lláh. The word is not a noun meaning the religion as a whole. It is derived from the ArabicBahá‘ (بهاء), meaning "glory" or "splendor", although the word Bahá'í is actually Persian from the Arabic root (the í suffix is Persian).[note 2] The term "Bahaism" (or "Baha'ism") is still used, mainly in a pejorative sense.
