Bahá'u'lláh is the Founder of the Bahá'í Faith and the latest in the line of Divine Messengers sent by God to guide humanity.
The Báb is the Herald of the Bahá'í Faith. He prepared the way for Bahá'u'lláh and taught that a greater Messenger would soon appear.
'Abdu'l-Bahá was the eldest son of Bahá'u'lláh and the appointed Interpreter of His teachings. His example of service and love is central to Bahá'í life.
