Russian Constituent Assembly
Victor Ardashev, a first cousin of Vladimir Lenin, was a member of the Constitutional Democratic Party from Verkhoturye, Perm Governorate. After the dispersion of the Russian Constituent Assembly, he published a critical proclamation and was murdered (under pretext of attempts to escape) by Yakov Yurovsky in February 1918. Incidentally, the same Yurovsky was the chief executioner of the last Russian Emperor Nicholas II.
