The Bahá'í Faith (Persian: Bahā'i ; بهائی) 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, coupled with 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 imprisoned and exiled from Persia to the Ottoman Empire because of his association with the Babi movement. He was still officially under house arrest at the time of his death, more than forty years later. Under the leadership of his son, `Abdu'l-Bahá, the religion gained a footing in Europe and America, but it still suffers intense persecution where it originated, in present-day Iran. 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. It is estimated that there are more than 5 million Bahá'ís around the world in more than 200 countries and territories.
