Rare photos of "military exercises" during the Qajar era

The occupation of Iran during World War I (1914–18) by Russian, British, and Ottoman troops was a blow from which Aḥmad Shāh never effectively recovered. With a coup d’état in February 1921, Reza Khan (ruled as Reza Shah Pahlavi, 1925–41) became the preeminent political personality in Iran; Aḥmad Shāh was formally deposed by the majlis (national consultative assembly) in October 1925 while he was absent in Europe, and that assembly declared the rule of the Qājār dynasty to be terminated.
