What day was Tsar Nicolas killed?
Execution of the Romanov family
night of 16–17 July 1918
The Russian Imperial Romanov family (Tsar Nicholas II, his wife Tsarina Alexandra and their five children Olga, Tatiana, Maria, Anastasia, and Alexei) and all those who chose to accompany them into imprisonment—notably Eugene Botkin, Anna Demidova, Alexei Trupp and Ivan Kharitonov, according to the conclusion of the investigator Sokolov, were shot and bayoneted to death[1][2] in Yekaterinburg on the night of 16–17 July 1918.[3] According to the official state version in the USSR, former Tsar Nicholas Romanov, along with members of his family and retinue, was executed by firing squad, by order of the Ural Regional Soviet, due to the threat of the city being occupied by Whites (Czechoslovak Legion)[4][5]. By the assumption of a number of researchers, this was done according to instructions by Lenin, Yakov Sverdlov and Felix Dzerzhinsky. Their bodies were then taken to the Koptyaki forest where they were stripped and mutilated.[6][2]  In 1919, White Army investigation (of Sokolov) failed to find the gravesite, concluding that the imperial family's remains had been cremated at the mineshaft called Ganina Yama, since evidence of fire was found.[7]. In 1979 and 2007, the remains of the bodies were found in two unmarked graves in a field called Porosenkov Log.[8]
