Pyotr_Voykov--Alexandra_Feodorovna_(Alix_of_Hesse)

Pyotr Lazarevich Voykov (Russian: Пётр Лазаревич Войков; Ukrainian: Петро Лазарович Войков, romanized: Petro Lazarovych Voikov; party aliases: Пётрусь and Интеллигент, or Piotrus and Intelligent) (August 13 [O.S. August 1] 1888 – June 7, 1927) was a Ukrainian Bolshevik revolutionary and Soviet diplomat known as one of the participants in the decision to execute the former Russian Emperor Nicholas II and his family members.
Minister Plenipotentiary of the Soviet Union to the Polish Republic (1924–1927), he was assassinated in Warsaw by a White émigré. The use of Voykov's name in toponymy in modern Russia has been a cause of notable controversy.
