Grand Duke Sergei Alexandrovich of Russia
Between 1891 and 1905, Grand Duke Sergei served as Governor General of Moscow. His reputation was tarnished as he was partially blamed for the Khodynka Tragedy, which, during the festivities following the coronation of Emperor NicholasII, resulted in thousands of deaths. As a Governor of Moscow, Grand Duke Sergei was responsible for the expulsion of Moscow's 20,000 Jews at the start of his tenure, and he repressed a student movement to prevent the spread of revolutionary ideas. His conservative policies, extreme even by contemporary standards, made him a polarizing figure, and he was regarded as a reactionary. In 1894 Grand Duke Sergei was made a member of the State Council. In 1896 he was promoted to Lieutenant General and appointed as Commander of Moscow military district. After thirteen years of service, Grand Duke Sergei resigned from the Governorship on January1, 1905. Targeted by the SR Combat Organization, he was assassinated by a terrorist bomb at the Kremlin.
