Prime Minister of Iran Dr. Mohammad Mossadegh's Overthrow

In August 1953, the Shah finally agreed to Mossadegh's overthrow, after Roosevelt told that the U.S. would proceed with him or without him and formally dismissed the Prime Minister in a written decree, an act that had been made part of the constitution during the Constitution Assembly of 1949, convened under martial law, at which time the power of the monarchy was increased in various ways by the Shah himself. As a precautionary measure, he flew to Baghdad and from there hid safely in Rome. He actually signed two decrees, one dismissing Mosaddegh and the other nominating the CIA's choice, General Fazlollah Zahedi, as Prime Minister. These decrees, called Farmāns, were specifically written as dictated by Donald Wilber the CIA architect of the plan, which were designed as a major part of Wilber's strategy to give the impression of legitimacy to the secret coup, as can be read in the declassified plan itself which bears his name. Wilber was later given a letter of commendation by Alan Dulles, CIA head, for his work. It too is now declassified, and appears in Wilber's autobiography.[citation needed]
Tehran strongman Shaban Jafari played a major role in Mossadegh's overthrow.
Soon, massive protests, engineered by Roosevelt's team, took place across the city and elsewhere with tribesmen paid to be at the ready to assist the coup. Anti- and pro-monarchy protesters, both paid by Roosevelt,[ violently clashed in the streets, looting and burning mosques and newspapers, leaving almost 300 dead. The pro-monarchy leadership, chosen, hidden and finally unleashed at the right moment by the CIA team, led by retired army General and former Minister of Interior in Mosaddegh's cabinet, Fazlollah Zahedi joined with underground figures such as the Rashidian brothers and local strongman Shaban Jafari, to gain the upper hand on 19 August 1953 (28 Mordad). The military joined on cue: pro-Shah tank regiments stormed the capital and bombarded the prime minister's official residence, on Roosevelt's cue, according to his book. Mosaddegh managed to flee from the mob that set in to ransack his house, and, the following day, surrendered to General Zahedi, who was meanwhile set up by the CIA with makeshift headquarters at the Officers' Club. Mosaddegh was arrested at the Officers' Club and transferred to a military jail shortly after. On 22 August, the Shah returned from Rome.
Zahedi's new government soon reached an agreement with foreign oil companies to form a consortium and "restore the flow of Iranian oil to world markets in substantial quantities", giving the U.S. and Great Britain the lion's share of Iran's oil. In return, the U.S. massively funded the Shah's resulting government, including his army and secret police force, SAVAK, until the Shah's overthrow in 1979.
As soon as the coup succeeded, many of Mosaddegh's former associates and supporters were tried , imprisoned, and tortured. Some were sentenced to death and executed. The minister of Foreign Affairs and the closest associate of Mosaddegh, Hossein Fatemi, was executed by order of the Shah's military court. The order was carried out by firing squad on October 29, 1953
