Holy Martyrdom Of the Imperial Royal Martyrs of Russia
Leon Trotsky -- one of Lenin's closest colleagues -- had revealed years earlier that Lenin and Sverdlov had together made the decision to put the Tsar and his family to death. Recalling a conversation in 1918, Trotsky wrote:
My next visit to Moscow took place after the [temporary] fall of Ekaterinburg [to anti-Communist forces]. Speaking with Sverdlov, I asked in passing: "Oh yes, and where is the Tsar?"
"Finished," he replied. "He has been shot."
"And where is the family?"
"The family along with him."
"All of them?," I asked, apparently with a trace of surprise.
"All of them," replied Sverdlov. "What about it?" He was waiting to see my reaction. I made no reply.
"And who made the decision?," I asked.
"We decided it here. Ilyich [Lenin] believed that we shouldn't leave the Whites a live banner to rally around, especially under the present difficult circumstances."
I asked no further questions and considered the matter closed. (The Jewish Role in the Bolshevik Revolution and Russia's Early Soviet Regime)
