Iranian monarchism is the advocacy of restoring the constitutional monarchy in Iran, which was abolished after the 1979 Revolution.
Iran first became a constitutional monarchy in 1905, but underwent a period of autocracy during the years 1925-1941, after which the Iranian National Assembly was restored to power. 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. In practice, however, his position was largely ceremonial, similar to that of Queen Elizabeth II.
In March 15, 1951, the National Assembly, led by Prime Minister Hossein Ala, unanimously voted to nationalize the oil industry, which at the time was dominated by the Anglo-Iranian Oil Company (now BP). In 1953, the British MI6 and American CIA orchestrated a coup against Mohammed Mossadegh's government. Agents fueled rumors that the republican-minded Mossadegh was planning on abolishing the monarchy and declaring himself President of a new Republic of Iran, leading to a pro-monarchist backlash from the public and leading to a successful result in the coup against the prime minister.
The Shah, who had gone into exile during the coup, returned to Iran and named General Fazlollah Zahedi as the new prime minister. Many contemporary sources attribute the coup, or counter coup, entirely to the U.S. American CIA (CIA Coup) and agents of the British MI6 who are reported to have organized and paid for it. These sources point to many other coups in which the CIA was instrumental, such as those in Congo (1964), Chile (1973), and Algeria (1991). Monarchists, however, argue that the counter-coup was in fact a popular uprising, and that the foreign intelligence agencies' undeniable involvement was peripheral. At least some historians argue the coup could not have taken place without both CIA organizing and Iranian support.
