revolutionary who violently opposed both the imperial and the Soviet regimes in Russia. He wrote several pseudonymous novels based on his career as a terrorist.

Savinkov joined the Socialist-Revolutionary Party in 1903 and was a leader of its terrorist organization. He was responsible for the assassination of the antiliberal government minister Vyacheslav Konstantinovich Plehve (1904) and of the grand duke Sergey Aleksandrovich (1905), the tsar's uncle and governor-general of Moscow.

During World War I, Savinkov served in the French army. After the February Revolution, he returned to Russia (1917) and became a military commissar and then deputy minister of war. The leadership of the provisional government was, it seemed, being concentrated in a triumvirate: the prime minister A.F. Kerensky, Gen. L.G. Kornilov, and Savinkov. In August 1917, however, Savinkov supported Kornilov against Kerensky in an unsuccessful “mutiny” and was forced to resign.

After the Bolshevik Revolution, Savinkov established a clandestine military organization, the Union for the Defense of the Fatherland and Freedom. This group organized an uprising in Yaroslavl (July 6–21, 1918) that was intended to coincide with an Allied invasion of Russia and to stimulate a nationwide rebellion against the Bolsheviks.

After the uprising failed, Savinkov went to Paris to solicit Allied intervention against the Soviet government. Invited to Warsaw in January 1920 by Józef Piłsudski, head of the Polish state, Savinkov organized a Russian volunteer corps to fight with the Polish Army. But when the Polish–Soviet peace treaty was signed at Riga (March 18, 1921), he returned, disillusioned, to Paris.

Savinkov apparently was tricked into returning to the U.S.S.R. Arrested in Minsk on Aug. 18, 1924, he received a death sentence 11 days later. This was commuted to imprisonment, but the next year he was stated to have committed suicide in Lubianka Prison, Moscow.
