diplomat who executed Soviet foreign policy from 1918 until 1928.

An aristocrat by birth, Chicherin entered the imperial diplomatic service after graduating from the University of St. Petersburg (1897). He became involved in the Russian revolutionary movement, however, and in 1904 resigned his post, renounced title to his estates, and went to Berlin, where he joined the Menshevik faction of the Russian Social Democratic Party (1905). For the next 12 years he devoted himself to party activities, working closely with the French Socialists and the British labour movement.

During World War I he took part in pacifist and relief activities in London. After the Bolsheviks seized power in Russia (October 1917, O.S.), the British arrested him and, in exchange for their ambassador, Sir George Buchanan, released him on Jan. 3, 1918. Chicherin returned to Russia and joined the Bolshevik Party. He then resumed his diplomatic career, participating in the final stage of negotiating the Brest-Litovsk peace treaty with Germany and subsequently becoming people's commissar for foreign affairs (May 1918). After negotiating treaties resolving territorial and commercial disputes, Chicherin headed the Soviet delegation to the conference of European nations held at Genoa to consider reconstruction of the European economy (1922). There he secretly negotiated the Treaty of Rapallo with Germany (signed April 16, 1922), which established normal commercial and diplomatic relations between the two countries and thereby ended the diplomatic and economic isolation that had been imposed on Russia and Germany after World War I. Although he had little influence in determining the foreign policies of the Soviet Union, Chicherin continued to carry them out skillfully until illness prevented him from performing his duties in 1928; he retired in 1930.
