There were a succession of Soviet secret police agencies over time. The Okhrana was abolished by the Provisional government after the first revolution of 1917, and the first secret police after the October Revolution, created by Vladimir Lenin's decree on December 20, 1917, was called "Cheka" (ЧК). Officers were referred to as "chekists", a name that is still informally applied to people under the Federal Security Service of Russia, the KGB's successor in Russia after the dissolution of the Soviet Union.
For most agencies listed here, secret policing operations were only part of their function; for instance, the KGB was both a secret police and an intelligence agency.
