Prime minister After returning to Iran, he became an interpreter for
Naser al-Din Shah. Later he served as Finance Minister, then as Governor, and for a short time as Prime Minister during the period of the
Constitutional Revolution of Iran in the reign of
Mohammed Ali Shah Qajar in 1907. However, under pressure from some parliamentarians he resigned. Because he failed to ask Mohammed Ali Shah for his permission before resigning, the latter had him arrested. Naser al-Molk was released from prison only after an intervention by the British ambassador. Seeing his life threatened, he fled to England.
Regent He did not return to Iran until after the fall of Mohammed Ali Shah in the summer of 1909 where he was installed as Regent for the infant
Ahmad Shah Qajar and assumed the office of prime minister once again for a short time. He held the office of Regent until Ahmad Shah came of age in 1914. In a deep political character analysis of Naser al-Molk, the American treasurer-general of Persia
William Morgan Shuster suggested that he showed a lack of strong leadership in his office. ==Life in England==
