In June Amin-ad-daulah was made prime minister (vizir azim) and given more extended powers, and in August raised to the dignity of grand vizier (sadr azim).
By Muzaffar-ud-Din Shah, Mahommed Ali Mirza (his successor) and the grand vizir, on the 3oth of December 1906, deals with the rescript of the 5th of August, states the powers and duties of the national council and makes provision for the regulation of its general procedure by the council itself.
The executive government is carried on under a cabinet composed of seven or eight vizirs (ministers), of whom one, besides holding a portfolio, is vizir azam, prime minister.
Until 1906 the shah was assisted in the task of government by the sadr azam (grand vizir), a number of vizirs, ministers or heads of departments somewhat on European lines, and a grand council of state, composed of some ministers and other members nominated by the shah himself as occasion required.
The ministers were not responsible to the Crown in a way that ministers of a European government are: they rarely took any initiative, and generally referred their affairs to the grand vizir or to the shah for final decision.
