Ali al-Ridha
As of 1921, Urmia was also called, "Urumia" and "Urmi". During the Pahlavi Dynasty (1925–1979), the city was called "Rezaiyeh" () after Reza Shah, the dynasty's founder, whose name ultimately derives from the Islamic concept of "rida" via the Eighth Imam in Twelver Shia Islam, Ali al-Ridha.
