During the years 1941 to 1953, Iran remained a constitutional monarchy and active parliamentary democracy with Shah Mohammad Reza Pahlavi retaining extensive legal executive powers.
[3][4] Afterwards, the era of constitutional monarchy gradually came to an end as the Shah increasingly exercised his executive powers unilaterally, thus leading towards the development of autocracy.
Under increasing international pressure, particularly from President Jimmy Carter of the United States, the Shah pushed forward major democratic reforms in the late 1970s, designed to gradually restore the constitutional monarchy as it had originally been.
Based in Paris, France, with other military officials of the Imperial Armed Forces and Prince Shahriar Shafiq, he established Azadegan, a paramilitary resistance intended to help restore the constitutional monarchy.
Fearing a growing counter-revolution, Prince Shahriar was assassinated in Paris in December 1979 by Khomeinist agents, which was a major setback for the monarchist resistance.
Despite a number of successful operations which garnered international media attention in 1980 and 1981, the outbreak of war between Iran and Iraq officially brought any hope for counter-revolution to an end.
