The Baháʼí Faith (; Persian: بهائی Bahāʼi) is a new religion teaching the essential worth of all religions and the unity of all people. Established by Baháʼu'lláh in the 19th century, it initially developed in Persia and parts of the Middle East, where it has faced ongoing persecution since its inception. The religion is estimated to have over five million adherents, known as Baháʼís, spread throughout most of the world's countries and territories.The religion has three central figures: the Báb (1819–1850), considered a herald who taught that God would soon send a prophet in the same way of Jesus or Muhammad and who was executed by Iranian authorities in 1850; Baháʼu'lláh (1817–1892), who claimed to be that prophet in 1863 and faced exile and imprisonment for most of his life; and his son, ʻAbdu'l-Bahá (1844–1921), who was released from confinement in 1908 and made teaching trips to Europe and the United States. After ʻAbdu'l-Bahá's death in 1921, leadership of the religion fell to his grandson Shoghi Effendi (1897–1957). Baháʼís annually elect local, regional, and national Spiritual Assemblies that govern the religion's affairs. 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 Baháʼí community that is located in Haifa, Israel, near the Shrine of the Báb.
According to the Baháʼí teachings, God is single and all-powerful. Baháʼu'lláh taught that religion is revealed in an orderly and progressive way by Manifestations of God, who are the founders of major world religions throughout history; Buddha, Jesus, and Muhammad are noted as the most recent of these before the Báb and Baháʼu'lláh. Baháʼís regard the major religions as fundamentally unified in purpose, though varied in social practices and interpretations. The Baháʼí Faith stresses the unity of all people, explicitly rejecting racism and nationalism. At the heart of Baháʼí teachings is the goal of a unified world order that ensures the prosperity of all nations, races, creeds, and classes.Letters written by Baháʼu'lláh to various people, including some heads of state, have been collected and assembled into a canon of Baháʼí scripture. This includes works by his son ʻAbdu'l-Bahá, and the Báb, who is regarded as Baháʼu'lláh's forerunner. Prominent among Baháʼí literature are the Kitáb-i-Aqdas, the Kitáb-i-Íqán, Some Answered Questions, and The Dawn-Breakers.
