Vissarion Vissarionovich "Beso" Lominadze (Russian: Виссарион Виссарионович Ломинадзе, Georgian: ბესარიონ ლომინაძე, 1897-1935), was a Georgian revolutionary and Soviet politician. The head of the Transcaucasian Oblast organization of the All-Russian Communist Party (Bolsheviks) [VKP(b)], Lominadze is best remembered as a participant in the Syrtsov-Lominadze affair of 1930, a failed attempt to reign in the growing power of Communist Party General Secretary Joseph Stalin.
Lominadze committed suicide in 1935.
Vissarion Vissarionovich Lominadze, best known by the Georgian diminutive "Beso," was born in Kutaisi, Georgia (then part of Imperial Russia) on June 6 (May 25 O.S.), 1897 into the family of a teacher. Beginning in 1913 he participated in student Social Democratic organizations in Kutaisi and St. Petersburg, and from April 1917 he worked in the military organization of the Petrograd branch of the Bolshevik party. In August he became secretary of the Party Committee of Kutaisi.
From 1918 to 1919 he was chairman of the Tbilisi Party Committee, and from 1919 to 1920 he was a member of the Baku Committee and a member of the Presidium of the Communist Party of Azerbaijan. From 1920 to 1921 he was a member of the Bureau of the Oryol regional committee of the party, and from 1921 to 1922 a party organizer in the Vyborg district of Petrograd, where he was involved in the suppression of the Kronstadt rebellion.
In October 1922 Lominadze was elected First Secretary of the Georgian Communist Party, a post he held until August 1924. Ronald Grigor Suny writes: "An old friend of Stalin's and the choice of the Orgburo in Moscow (but not the local party), Lominadze was nevertheless somewhat above the infighting that was tearing the KPG apart." From 1925 to 1929 he worked in the Comintern as well as being Secretary of the Board of the Communist Youth International from 1925 to 1926.
