Hasan Ali Mansur (‎; 13 April 1923 – 26 January 1965) was an Iranian politician who served as Prime Minister from 1964 to 1965. He served during the White Revolution of the Shah Mohammad Reza Pahlavi and was assassinated by a member of the Fada'iyan-e Islam. Early life and education Hassan Ali was born in Tehran on 13 April 1923 to Prime Minister Ali Mansur (Mansour-al-Molk) and daughter of Zahir-ol-Molk Raiss. He received primary education in Tehran and graduated from Firooz-Bahram High School. During the World War II era, he entered Law School at the University of Tehran and graduated with a degree in political science. Career In the post World War II era, Mansour started his political career by entering the foreign ministry and completed several internal and foreign assignments including tours of Germany and France. In the 1950s, this thirty-year-old was twice appointed chief of prime minister's office, first for a brief period because of change in government, and second lasted for 2 years. In 1957, Prime Minister Manuchehr Eghbal appointed him as chairman of the economics council and vice prime minister. He also held the positions of minister of labor, and minister of trade. Prime minister Asadollah Alam appointed him as chairman of "Bimeh Iran" insurance company. The Progressive Party or "Kanoon Motaraghion" was founded by Mansour to conduct economic policy research as well as the launching pad for his future prime ministership. In 1962 Mansour ran for the 21st Majlis and was elected as the second representative from Tehran, after Abdollah Riazi, speaker of the Majlis. A few dozen of his party members were also elected to Majlis, with the exception of Hoveyda and Kashefian who were more interested in executive branch. Mansour then expanded his power base by forming a coalition and founded "IRAN NOVIN" party with a majority of 175 out of 230 deputies, and was elected the Majority Leader of Parliament. After Alam resigned his premiership in 1964, Mohammad Reza Pahlavi appointed Mansur prime minister and his cabinet was announced on 7 March. He introduced many young new faces, such as Amir Abbas Hoveyda, Jamshid Amuzegar, Ataollah Khosravani, Nahavandi, Alinaghi Alikhani, Manouchehr Rohani, and many other Iran Novin members. Since most of his cabinet were young and American/European educated, Mansour had pro-American tendencies in his politics and enjoyed the support of American government. Clearly the Shah now felt more comfortable working with people
