Ø±ÙˆØØ´ شاد, Bahá'u'lláh.  Born MÃrzá Ḥusayn-`Alà Núrà in Persia in 1817, Bahá'u'lláh’s teachings focus on the unity of God and mankind, with the hopeful mission of spiritually unifying the entire planet through the eventual eradication of racism and nationalism.  Needless to say (alas, alas), he was imprisoned by the Ottomans and his followers have been persecuted and sometimes executed for their beliefs (particularly in Iran, but also in other predominately Muslim countries, where the Bahá'à faith is considered an apostasy from Islam).  Bahá'u'lláh died on this date in 1892 at the age of 74.
