In the Baha'i faith, today is one of the nine holy days, the Birth of Bahá'u'lláh, who is the founder of the faith. He was born in Tehran on November 12, 1817, named Mírzá Ḥusayn-`Alí Núrí . He is considered one of God's messengers and he fulfillment of eschatological hopes of Christianity, Islam, and some other religions. As this site indicates, "Bahá'u'lláh taught that humanity is one single race and that the age has come for its unification in a global society. He taught that "there is only one God, that all of the world’s religions are from God, and that now is the time for humanity to recognize its oneness and unite." His claim to divine revelation resulted in persecution and imprisonment by the Persian and Ottoman authorities, and his eventual 24-year confinement in the prison city of `Akka, Palestine (present-day Israel), where he died [in 1892]. He wrote many religious works, most notably the Kitáb-i-Aqdas, the Kitáb-i-Íqán and Hidden Words."
