Nicholas II, Czar of Russia, was forced to sign a document of abdication on March 16, 1917, after being brought down by political unrest and widespread starvation stemming from Russia’s staggering losses in WWI. The czar, his wife Alexandra, their four daughters and son Alexis, heir to the throne, were held prisoner by the Bolsheviks for several months at Tsarskoye Selo palace near Petrograd. This photograph shows Nicholas II under guard in the park at Tsarskoye Selo. In August 1917, the family was transported to distant Siberia to prevent any attempt to restore them to the throne. In July 1918, the entire royal family was executed by local Bolsheviks.
