About Bahá'u'lláh Mirza Husayn Ali Nuri
Bahá'u'lláh was born on 12 November 1817, in Tehran, the capital of Persia (Iran) and was the founder of the Baha'i Faith, which is the youngest of the world's independent monotheistic religions--- Baha'i emphasizes the spiritual unity of all humankind.
Bahá'u'lláh's can allegedly be traced back to Abraham through Abraham's wife Keturah, to Zoroaster and to Yazdigird III, the last king of the Sassanid Empire, and also to Jesse father of King David.
Religious history, according to the Bahá'í Faith, is seen to have unfolded through a series of divine messengers such as Abraham, the Buddha, Jesus, Muhammad and most recently the Bahá'u'lláh. Thus humanity is understood to be in a process of collective evolution, and the need of the present time is for the gradual establishment of unity on a global scale leading to peace and justice for all mankind.
Baha'u'llah's mother was Khadíjih Khánum and his father was Mírzá Buzurg. Bahá'u'lláh's father, Mírzá Buzurg, served as vizier to Imám-Virdi Mírzá, the twelfth son of Fat′h Ali Shah Qajar. Mírzá Buzurg was later appointed governor of Burujird and Lorestan, a position that he was stripped of during a government purge when Muhammad Shah came to power.
After the death of his father, Bahá'u'lláh was asked to take a government post by the new vizier Haji Mirza Aqasi, but declined.
Bahá'u'lláh was married three times. He married his first wife Ásíyih Khánum, the daughter of a nobleman, in Tehran in 1835, when he was 18 and she was 15. She was given the title of The Most Exalted Leaf and Navváb.
His second marriage was to his widowed cousin Fátimih Khánum, in Tehran in 1849 when she was 21 and he was 32. She was known as Mahd-i-
His third marriage to Gawhar Khánum occurred in Baghdad sometime before 1863.
Bahá'u'lláh declared Ásíyih Khánum his "perpetual consort in all the worlds of God", and her son
Abdu'l-Bahá as his vicar. He had 14 children, ten sons and four daughters, of which five sons predeceased him.
Bahá'ís regard Ásíyih Khánum and her children Mírzá Mihdí, Bahiyyih Khánum and 'Abdu'l-Bahá to be the Bahá'í holy family.
