The Bahá'í faith is considered to be one of the youngest religious sects in the world. Starting in the 19th century the Bahá'í follow the teachings of Bahá'u'lláh, himself a follower of the prophecies of Mirza Ali Muhammad, known as the Bab. The central theme of Bahá'u'lláh's message is that humanity is one single race and that the day has come for its unification in one global society. The Bahá'í believe that Bahá'u'lláh was the next manifestation of God following Zoroaster, Buddha, Jesus and Mohammed.
