The Bahá'í Faith is a monotheistic religion founded in the 19th century by Bahá'u'lláh in Persia, now Iran. It emphasizes the unity of all religions and the oneness of humanity, teaching that all major world religions come from the same divine source. Followers believe in the importance of global peace, justice, and equality. Central to the Bahá'í Faith is the belief in progressive revelation, which means that God sends messengers, such as Moses, Jesus, Muhammad, and Bahá'u'lláh, to guide humanity. The faith encourages community building, education, and service to others, aiming to create a harmonious and just society.
