The Qajar dynasty was overthrown in 1925, replaced by the Pahlavi dynasty. Both reigning members of this dynasty, Reza Shah Pahlavi (r. 1925–1941) and Mohammad Reza Pahlavi (r. 1941–1979), before they too were overthrown as part of the Iranian revolution in 1979, used the title of "Shahanshah". Although Mohammad Reza Pahlavi had reigned as "Shah" for twenty-six years by then, he only took the title of "Shahanshah" on 26 October 1967 in a lavish coronation ceremony held in Tehran. He said that he chose to wait until this moment to assume the title because in his own opinion he "did not deserve it" up until then; he is also recorded as saying that there was "no honour in being Emperor of a poor country" (which he viewed Iran as being until that time). The current head of the exiled house of Pahlavi, Reza Pahlavi II, symbolically declared himself "Shahanshah" at the age of 21 after the death of his father in 1980.
