Mohammad Beg (Persian: محمد بیگ; died 1672), was a Muslim of Armenian origin, who served as the Grand Vizier of the Safavid king (shah) Abbas II (r. 1642–1666) from 1654 to 1661.
[1][2] Mohammad Beg is first mentioned in 1643, when he was appointed as the city prefect of New Julfa, a quarter in the Safavid capital of Isfahan, which was populated by Armenians.
[5][6] Mohammad Beg also had the empire more centralized by converting more land into the crown domain (Hamadan in 1654, Ardabil in 1656/7, Semnan in 1656/7 and Kerman in 1658).
[7][8][9] In 1661, Mohammad Beg, after having failed to diminish the power of his rivals, was forced to resign from the grand vizier office.
According to the French traveler Jean Chardin, Mohammad Beg had been poisoned by Suleiman's grand vizier Shaykh Ali Khan Zangana.
