The Bahá'í Faith (Persian: بهائیت‎ Bahá'iyyat, Arabic: بهائية‎‎ Bahá'iyya /bəˈhaɪ/) is a monotheistic religion which emphasizes the spiritual unity of all humankind. Three core principles establish a basis for Bahá'í teachings and doctrine: the unity of God, that there is only one God who is the source of all creation; the unity of religion, that all major religions have the same spiritual source and come from the same God; and the unity of humanity, that all humans have been created equal, and the unity in diversity, that diversity of race and culture are seen as worthy of appreciation and acceptance. According to the Bahá'í Faith's teachings, the human purpose is to learn to know and to love God through such methods as prayer, reflection and being of service to humanity.

The Bahá'í Faith was founded by Bahá'u'lláh in 19th-century Persia. Bahá'u'lláh was exiled for his teachings from Persia to the Ottoman Empire and died while officially still a prisoner. After Bahá'u'lláh's death, under the leadership of his son, `Abdu'l-Bahá, the religion spread from its Persian and Ottoman roots, and gained a footing in Europe and America, and was consolidated in Iran, where it suffers intense persecution. After the death of `Abdu'l-Bahá, the leadership of the Bahá'í community entered a new phase, evolving from a single individual to an administrative order with both elected bodies and appointed individuals. There are probably more than 5 million Bahá'ís around the world in more than 200 countries and territories.

Beliefs
Three core principles establish a basis for Bahá'í teachings and doctrine: the unity of God, the unity of religion, and the unity of humanity. From these postulates stems the belief that God periodically reveals his will through divine messengers, whose purpose is to transform the character of humankind and to develop, within those who respond, moral and spiritual qualities. Religion is thus seen as orderly, unified, and progressive from age to age.

God
The Bahá'í writings describe a single, personal, inaccessible, omniscient, omnipresent, imperishable, and almighty God who is the creator of all things in the universe. The existence of God and the universe is thought to be eternal, without a beginning or end. Though inaccessible directly, God is nevertheless seen as conscious of creation, with a will and purpose that is expressed through messengers termed Manifestations of God.

Bahá'í teachings state that God is too great for humans to fully comprehend, or to create a complete and accurate image of, by themselves. Therefore, human understanding of God is achieved through his revelations via his Manifestations. In the Bahá'í religion, God is often referred to by titles and attributes (for example, the All-Powerful, or the All-Loving), and there is a substantial emphasis on monotheism; such doctrines as the Trinity are seen as compromising, if not contradicting, the Bahá'í view that God is single and has no equal. The Bahá'í teachings state that the attributes which are applied to God are used to translate Godliness into human terms and also to help individuals concentrate on their own attributes in worshipping God to develop their potentialities on their spiritual path. According to the Bahá'í teachings the human purpose is to learn to know and love God through such methods as prayer, reflection, and being of service to others.

Religion
Bahá'í notions of progressive religious revelation result in their accepting the validity of the well known religions of the world, whose founders and central figures are seen as Manifestations of God. Religious history is interpreted as a series of dispensations, where each manifestation brings a somewhat broader and more advanced revelation that is rendered as a text of scripture and passed on through history with greater or lesser reliability but at least true in substance, suited for the time and place in which it was expressed. Specific religious social teachings (for example, the direction of prayer, or dietary restrictions) may be revoked by a subsequent manifestation so that a more appropriate requirement for the time and place may be established. Conversely, certain general principles (for example, neighbourliness, or charity) are seen to be universal and consistent. In Bahá'í belief, this process of progressive revelation will not end; however, it is believed to be cyclical. Bahá'ís do not expect a new manifestation of God to appear within 1000 years of Bahá'u'lláh's revelation.

Bahá'í beliefs are sometimes described as syncretic combinations of earlier religious beliefs. Bahá'ís, however, assert that their religion is a distinct tradition with its own scriptures, teachings, laws, and history. While the religion was initially seen as a sect of Islam, most religious specialists now see it as an independent religion, with its religious background in Shi'a Islam being seen as analogous to the Jewish context in which Christianity was established. Muslim institutions and clergy, both Sunni and Shia, consider Bahá'ís to be deserters or apostates from Islam, which has led to Bahá'ís being persecuted. Bahá'ís describe their faith as an independent world religion, differing from the other traditions in its relative age and in the appropriateness of Bahá'u'lláh's teachings to the modern context. Bahá'u'lláh is believed to have fulfilled the messianic expectations of these precursor faiths.

Human Beings
The Bahá'í writings state that human beings have a "rational soul", and that this provides the species with a unique capacity to recognize God's station and humanity's relationship with its creator. Every human is seen to have a duty to recognize God through His messengers, and to conform to their teachings. Through recognition and obedience, service to humanity and regular prayer and spiritual practice, the Bahá'í writings state that the soul becomes closer to God, the spiritual ideal in Bahá'í belief. When a human dies, the soul passes into the next world, where its spiritual development in the physical world becomes a basis for judgment and advancement in the spiritual world. Heaven and Hell are taught to be spiritual states of nearness or distance from God that describe relationships in this world and the next, and not physical places of reward and punishment achieved after death.

The Bahá'í writings emphasize the essential equality of human beings, and the abolition of prejudice. Humanity is seen as essentially one, though highly varied; its diversity of race and culture are seen as worthy of appreciation and acceptance. Doctrines of racism, nationalism, caste, social class, and gender-based hierarchy are seen as artificial impediments to unity. The Bahá'í teachings state that the unification of humanity is the paramount issue in the religious and political conditions of the present world.

Teachings

Summary
Shoghi Effendi, the appointed head of the religion from 1921 to 1957, wrote the following summary of what he considered to be the distinguishing principles of Bahá'u'lláh's teachings, which, he said, together with the laws and ordinances of the Kitáb-i-Aqdas constitute the bedrock of the Bahá'í Faith:

    The independent search after truth, unfettered by superstition or tradition; the oneness of the entire human race, the pivotal principle and fundamental doctrine of the Faith; the basic unity of all religions; the condemnation of all forms of prejudice, whether religious, racial, class or national; the harmony which must exist between religion and science; the equality of men and women, the two wings on which the bird of human kind is able to soar; the introduction of compulsory education; the adoption of a universal auxiliary language; the abolition of the extremes of wealth and poverty; the institution of a world tribunal for the adjudication of disputes between nations; the exaltation of work, performed in the spirit of service, to the rank of worship; the glorification of justice as the ruling principle in human society, and of religion as a bulwark for the protection of all peoples and nations; and the establishment of a permanent and universal peace as the supreme goal of all mankind—these stand out as the essential elements [which Bahá'u'lláh proclaimed]

Social Principles
The following principles are frequently listed as a quick summary of the Bahá'í teachings. They are derived from transcripts of speeches given by `Abdu'l-Bahá during his tour of Europe and North America in 1912. The list is not authoritative and a variety of such lists circulate.

•     Unity of God
•     Unity of religion
•     Unity of humanity
•     Unity in diversity
•     Equality between men and women
•     Elimination of all forms of prejudice
•     World peace and a New world order
•     Harmony of religion and science
•     Independent investigation of truth
•     Principle of Ever-Advancing Civilization
•     Universal compulsory education
•     Universal auxiliary language
•     Obedience to government and non-involvement in partisan politics unless submission to law amounts to a denial of Faith.
•     Elimination of extremes of wealth and poverty

With specific regard to the pursuit of world peace, Bahá'u'lláh prescribed a world-embracing collective security arrangement as necessary for the establishment of a lasting peace.

Mystical Teachings
Although the Bahá'í teachings have a strong emphasis on social and ethical issues, there exist a number of foundational texts that have been described as mystical. The Seven Valleys is considered Bahá'u'lláh's "greatest mystical composition." It was written to a follower of Sufism, in the style of  `Attar, The Persian Muslim poet, and sets forth the stages of the soul's journey towards God. It was first translated into English in 1906, becoming one of the earliest available books of Bahá'u'lláh to the West. The Hidden Words is another book written by Bahá'u'lláh during the same period, containing 153 short passages in which Bahá'u'lláh claims to have taken the basic essence of certain spiritual truths and written them in brief form.

Covenant
The Bahá'í teachings speak of both a "Greater Covenant", being universal and endless, and a "Lesser Covenant", being unique to each religious dispensation. The Lesser Covenant is viewed as an agreement between a Messenger of God and his followers and includes social practices and the continuation of authority in the religion. At this time Bahá'ís view Bahá'u'lláh's revelation as a binding lesser covenant for his followers; in the Bahá'í writings being firm in the covenant is considered a virtue to work toward. The Greater Covenant is viewed as a more enduring agreement between God and humanity, where a Manifestation of God is expected to come to humanity about every thousand years, at times of turmoil and uncertainty. With unity as an essential teaching of the religion, Bahá'ís follow an administration they believe is divinely ordained, and therefore see attempts to create schisms and divisions as efforts that are contrary to the teachings of Bahá'u'lláh. Schisms have occurred over the succession of authority, but any Bahá'í divisions have had relatively little success and have failed to attract a sizeable following. The followers of such divisions are regarded as Covenant-breakers and shunned, essentially excommunicated.
