Amanollah Khan Zia' os-Soltan (also Amanollah Khan Donboli "Nazer ol-Ayaleh" "Zia' os-Soltan") was an Iranian aristocrat and politician at Qajar court during the time of Mozaffar ad-Din Shah, Mohammad Ali Shah and Ahmad Shah Qajar and hero of the Persian Constitutional Revolution.
Amanollah Khan was born 1863 at Tabriz, died on 11 February 1931 by cancer in Hamburg when on a visit to see medical specialists, and was buried there at the Iranian-Muslim department of Ohlsdorf Cemetery. He was the son of Safar Khan from the Donboli family, who ruled as hereditary Khans the cities of Tabriz and Khoy. A wealthy big landowner Amanollah Khan held possession of half the city of Tabriz and large landed properties at Alamdar in the Iranian province of Azerbaijan (Iran).
This was also the reason he was sometimes called Tabrizi (meaning "from Tabriz"), because family names were unknown in Iran of that time. Later Mozaffar ad-Din Shah gave him the noble title "Zia' os-Soltan" (lit. "Splendour of the Sovereign") for his merits in affairs of state, by which he became popular. Firstly he married in 1897 Princess Shazdeh Khanom Malekeh-Afagh Bahman-Qajar, granddaughter of Prince Bahman Mirza Qajar, by whom he got his two children, the Shahzadehs Nosrat ol-Molouk Khanom Bahman and Abol Qassem Bahman. After her death in 1917 he married secondly in 1923 a rich landlady from Damghan, Turkan Aqa Khanom but without any issue.
In the time when Crown Prince Mozaffar ad-Din Mirza was heir apparent of Persia and had his seat of power in Tabriz, Amanollah Khan held the administrative post of Nazer ol-Ayaleh (lit. "Warden of the Province"). When in 1896 the new shah proclaimed Mozaffar ad-Din Shah (r. 1896-1906) took up residence at Tehran, Amanollah Khan came with the so-called Turki-fraction from Tabriz to Tehran, arose at court to the imperial entourage and was awarded with the title of "Zia' os-Soltan" by the shah. With his marriage to a Qajar princess - a cousin to the shah - Zia' os-Soltan was close related to the Imperial house. The family lived in the 1903 newly electric illuminated Tehran district of Cheragh-Bargh (lit. "electric light"), at the Khiyaban-e Cheragh Bargh ("Avenue Electric Light"). Thus, some sources also gave Zia' os-Soltan the sobriquet Cheragh-Barghi (lit. "Coming from Tcheragh-Bargh").
