Answer
The grand vizier, Saru Taqi, led Abbas II's regency, which was established after the death of Shah Suleiman in 1666. Saru Taqi's tenure as grand vizier was characterized by his efforts to reform the Safavid state, which had been weakened by the previous reign of Shah Suleiman. These reforms included efforts to improve the efficiency of the government, increase tax revenue, and strengthen the military.
