Мохаммед Реза Пехлеви
In the twentieth century, the Shah of Persia, Mohammad Reza Pahlavi, officially adopted the title "Šāhanšāh" and, in western languages, the rendering "Emperor". He also styled his wife "Shahbānu" ("Empress"). Mohammad Reza Pahlavi was the last Shah, as the Iranian monarchy was abolished after the 1979 Iranian Revolution.
