Meet Prince Babak Qajar

His son Moḥammad ʿAlī Shāh (reigned 1907–09), with the aid of Russia, attempted to rescind the constitution and abolish parliamentary government. In so doing he aroused such opposition that he was deposed in 1909, the throne being taken by his son. Aḥmad Shāh (reigned 1909–25), who succeeded to the throne at age 11, proved to be pleasure-loving, effete, and incompetent and was unable to preserve the integrity of Iran or the fate of his dynasty.
