| The Katyn massacre, also known as the Katyn Forest massacre (Polish: zbrodnia katyńska, 'Katyń crime') , was a mass murder of thousands of Polish military officers, policemen, intellectuals and civilian prisoners of war by Soviet NKVD, based on a proposal from Lavrentiy Beria to execute all members of the Polish Officer Corps dated March 5 1940. This official document was then approved (signed) by the entire Soviet Politburo including Stalin and Beria. The number of victims is estimated at about 22000, the most commonly cited number is 21768. The victims were murdered in the Katyn forest in Russia, the Kalinin (Tver) and Kharkov prisons and elsewhere. About 8000 were officers taken prisoner during the 1939 Soviet invasion of Poland, the rest being Poles arrested for allegedly being "intelligence agents, gendarmes, saboteurs, landowners , factory owners, lawyers, priests, and officials." Since Poland's conscription system required every unexempted university graduate to become a reserve officer, the Soviets were able to round up much of the Polish intelligentsia, and the Jewish, Ukrainian, Georgian and Belarusian intelligentsia of Polish citizenship. |
