- 26 October 1919 – 27 July 1980), also known as Mohammad Reza Shah ), was the last Shah of Iran from 16 September 1941 until his overthrow by the Iranian Revolution on 11 February 1979. Mohammad Reza Shah took the title Shahanshah on 26 October 1967. He was the second and last monarch of the House of Pahlavi. Mohammad Reza Shah Pahlavi held several other titles, including that of Aryamehr and Bozorg Arteshtaran . His dream of what he referred to as a "Great Civilisation" in Iran led to a rapid industrial and military modernisation, as well as economic and social reforms
Mohammad Reza gradually lost support from the Shi'a clergy of Iran as well as the working class, particularly due to his strong policy of modernisation, laïcité, conflict with the traditional class of merchants known as bazaari, relations with Israel, and corruption issues surrounding himself, his family, and the ruling elite. Various additional controversial policies were enacted, including the banning of the communist Tudeh Party and a general suppression of political dissent by Iran's intelligence agency, SAVAK. According to official statistics, Iran had as many as 2,200 political prisoners in 1978, a number which multiplied rapidly as a result of the revolution.
Several other factors contributed to strong opposition to the Shah amongst certain groups within Iran, the most significant of which were US and UK support for his regime, clashes with Islamists and increased communist activity. By 1979, political unrest had transformed into a revolution which, on 17 January, forced him to leave Iran. Soon thereafter, the Iranian monarchy was formally abolished, and Iran was declared an Islamic republic led by Ruhollah Khomeini. Facing likely execution should he return to Iran, he died in exile in Egypt, whose president, Anwar Sadat, had granted him asylum. Due to his status as the last Shah of Iran, he is often known as simply "The Shah".
