Chronology of Soviet secret police agencies Chronology of Soviet secret police agencies <br> There was a succession of Soviet secret police agencies over time. 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 the secret police and the intelligence agency.
Polish Operation of the NKVD were about 30%, while in the Belorussian SSR... the Polish minority was almost completely annihilated." Timothy Snyder gives a conservative estimate of 85,000 confirmed Poles executed simultaneously across the country. Almost all victims of the NKVD shootings were men, wrote Michał Jasiński, most with families. Their wives and children were dealt with by the NKVD Order № 00486. The women were generally sentenced to deportation to Kazakhstan for an average of 5 to 10 years. Their children were put in orphanages to be brought up as Soviet, with no knowledge of their origins. All possessions of the accused were confiscated.
