The Baha'i Faith is a monotheistic religion founded in the 19th century by Baha'u'llah 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. Baha'is believe in the importance of global peace, equality, and social justice. Central to the Baha'i Faith is the belief in progressive revelation, which means that God sends messengers, such as Jesus, Muhammad, and Baha'u'llah, to guide humanity. Baha'is follow the teachings of Baha'u'llah and strive to promote harmony among diverse cultures and religions.
