A few days after Bloody Sunday (1905), on 12 January 1905 (O.S.), Trepov was appointed in St. Petersburg (then the capital of the Russian Empire) to become Governor General of the Saint Petersburg Governorate with full power to forbid all congresses, associations, or meetings. He took his residence in the Winter Palace. Along with Plehve and Count Ignatyev Trepov promoted a policy of repression and anti-Jewish persecution. He personally edited pamphlets.
