The Gestapo–NKVD conferences were a series of secret police meetings organized in late 1939 and early 1940 by the German and Soviet officials following their joint invasion of Poland in accordance with the Nazi-Soviet alliance. The purpose of the meetings was to enable the German and Soviet security forces including Gestapo and NKVD respectively, to share information regarding their parallel terror operations in occupied Poland. In spite of their differences on other issues, both Heinrich Himmler and Lavrentiy Beria had common goals as far as the fate of Poland was concerned. The known conferences were devoted to coordinating plans for joint destruction of Polish nationhood as well as discussing ways of dealing with the Polish resistance during World War II.
