Rabkrin

The People's Commissariat of Workers' and Peasants' Inspection (ru: Народный комиссариат Рабоче-крестьянской инспекции, Narodnyi komissariat Raboche-krest'ianskoi inspektsii), commonly known as Rabkrin or RKI, was a ministerial-level department in the Soviet Union responsible for supervision and auditing of government and state enterprise operations. The commissariat was established in 1920, with Joseph Stalin serving as the first People's Commissar of RKI.

Originally intended as a mechanism for working class supervision over the bureaucracy, in the end the organization devolved into what historian Isaac Deutscher has described as "unofficial but meddlesome police in charge of the civil service." Rabkrin was finally dissolved in 1934, with its supervisory and law enforcement duties transferred to other Soviet state agencies.
