Mohammad Reza Pahlavi, commonly referred to in the Western world as Mohammad Reza Shah, or just simply The Shah, was the last monarch of Iran. He began ruling the Imperial State of Iran after succeeding his father Reza Shah in 1941 and remained in power until he was overthrown by the 1979 Iranian Revolution, which abolished the country's monarchy and established the Islamic Republic of Iran. In 1967, he took up the title Shahanshah and held several others, including Aryamehr and Bozorg Arteshtaran.

Mohammad Mosaddegh was an Iranian politician, author, and lawyer who served as the 30th Prime Minister of Iran from 1951 to 1953, elected by the 16th Majlis. He was a member of the Iranian parliament from 1923, and served through a contentious 1952 election into the 17th Iranian Majlis, until his government was overthrown in the 1953 Iranian coup d'état aided by the intelligence agencies of the United Kingdom (MI6) and the United States (CIA), led by Kermit Roosevelt Jr. His National Front was suppressed from the 1954 election.
