An early colour photograph of the Emir of Bukhara, Mohammed Alim Khan, in 1911, taken by Sergei Mikhailovich Prokudin-Gorskii as part of his work to document the Russian Empire from 1909 to 1915. Alim Khan, a direct descendant of Genghis Khan, was the last emir of the Manghit dynasty. He reigned from 1911 to 1920, fleeing to Afghanistan when the Bolsheviks annexed Bukhara and proclaimed the Bukharan People's Republic.
