The Iranian religion of Baha'i is a monotheistic faith founded in the 19th century by Bahá'u'lláh. It emphasizes the spiritual unity of all humankind and teaches that there is one God who has sent messengers to humanity throughout history, including Abraham, Moses, Jesus, Muhammad, and Bahá'u'lláh. Baha'i followers believe in the essential harmony of science and religion, and strive to create a global society of peace, justice, and unity.
