The Government of the Russian Soviet Federative Socialist Republic was known officially as the Council of People's Commissars (Sovnarkom) from 1917–1946. (From 1946 to 1978, it was called the Council of Ministers and from 1978 to 1991 it was called the Council of Ministers–Government.)
Speaking in June 2013, the Russian president, Vladimir Putin, described the Sovnarkom formed shortly after the October Revolution in 1917 as 'the first Soviet government, whose composition was 80-85 percent Jewish'. How true was this? According to Wikipedia, the first council elected by the Second All-Russian Congress of Soviets on 8 November 1917 was composed as follows: Vladimir Lenin, Nikolai Gorbunov, Vladimir Milyutin, Vladimir Antonov-Ovseyenko, Nikolai Krylenko, Pavel Dybenko, Viktor Nogin, Anatoly Lunacharsky, Ivan Teodorovich, Leon Trotsky, Alexei Rykov, Georgy Oppokov, Alexander Shlyapnikov, Joseph Stalin, Nikolai Glebov-Avilov and Ivan Skvortsov-Stepanov. At a Sovnarkom session between December 1917 and January 1918, those present included the following: Isaac N. Steinberg, Ivan Skvortsov-Stepanov, Boris Kamkov, Vladimir Bonch-Bruyevich, V. E. Trutovsky, Alexander Shlyapnikov, P. P. Proshyan, Vladimir Lenin, Joseph Stalin, Alexandra Kollontai, Pavel Dybenko, E. K. Kosharova, Nikolai Podvoisky, Nikolai Gorbunov, V. I. Nevsky, Alexander Shotman, Georgy Chicherin.
