Baha'u'llah was a Persian religious leader and the founder of the Baha'i Faith. He taught that humanity is one single race and believed in the unity of all religions, proclaiming that all major religions come from the same God and that their basic teachings are compatible. Baha'u'llah spent much of his later life imprisoned or exiled for his teachings by the Ottoman Empire and died as a prisoner in Ottoman Palestine in 1892.
