The nomenklatura

And yet who was to control the controllers? The Bolshevik leaders assumed that things would be fine so long as public institutions, especially the control organs, drew their personnel mainly from Bolsheviks and pro-Bolshevik workers. But how were the leaders to know who among such persons were genuinely reliable? Under the NEP the system known as the nomenklatura was introduced. Since mid-1918, if not earlier, the central party bodies had made the main appointments to Sovnarkom, the Red Army, the Cheka and the trade unions. In 1923 this system was formalized by the composition of a list of about 5,500 designated party and governmental posts – the nomenklatura – whose holders could be appointed only by the central party bodies. The Secretariat’s Files-and-Distribution Department (Uchraspred) compiled a file-index on all high-ranking functionaries so that sensible appointments might be made.
