Hajji Mohammad Hossein Isfahani

Hajji Mohammad Hossein Isfahani (; 1758–1823) was an architect and political leader in Isfahan during the rule of Fath-Ali Shah Qajar, the second shah of Qajar Iran.

Biography He was born in Isfahan, Iran. In 1795 or 1796 he was named governor (beglarbegi) of Isfahan, Qom, and Kashan. In this role, Mohammad Hossein invested heavily in agriculture, which increased his own wealth and contributed to Isfahan's economic revival. In 1806, he was appointed mostowfi ol-mamalek, given the title Amin ol-Dowleh, and his son, Abd ol-Hossein Khan Isfahani succeeded him as beglarbegi. In 1809, Mohammad Hossein presented the Peacock Throne to the shah at the shah's marriage to Tavus Khanum Taj ol-Dowleh. In 1813, he was given the title Nizam ol-Dowleh. In 1818, Mirza Shafi Mazandarani died and Mohammad Hossein was appointed to the position of sadr-e a'zam which he held until his death in 1823.

Mohammad Hossein was close to Scottish diplomat John Macdonald Kinneir, whose reports play an important role in our understanding of Mohammad Hossein's career and building. Mohammad Hossein's term as governor led to the Qajar era's most extensive renovation and construction projects in Isfahan. He renovated the Jameh Mosque and the Madrasa-e Abdallah. He built three madrasas, including Sadr Madrasa, built a new palace, renovated many bazaars, restored and expanded the canal system, and enclosed slums. He removed the famous clock in Naqsh-e Jahan Square, rebuilt parts of the Safavid Haft Dast palace and renovated the Bagh-e Angurestan, the Hasht Behesht, and the Talar-e Tavila. He also built a new avenue through the Khaju quarter, Chahar Bagh-e Chinarsu (aka Bagh-e Now and Bagh-e Sadri). He also constructed the royal garden, Emarat-e Sadr (aka Emarat-e Now). Mohammad Hossein was not universally praised, Rostam al-Hokama considered him an "uneducated parvenu" and claimed that Mohammad Hossein and his brothers had stolen the possessions and royal insignia of Jafar Khan Zand when Zand fled to Shiraz in 1785.

Mohammad Hossein's son, Mohammad Ibrahim Khan Nazir ol-Dowleh, married one of the Fath Ali Shah's daughters (Khadijeh Soltan Begom, "Esmat-ed-Dowleh) and Khan's daughter married Hossein Ali Mirza Farmanfarma, governor of Shiraz. Khan died on 19 October 1823.
