The Gestapo–NKVD conferences were a series of security police meetings organised in late 1939 and early 1940 by Germany and the Soviet Union, following the invasion of Poland in accordance with the Molotov–Ribbentrop Pact. The meetings enabled both parties to pursue specific goals and aims as outlined independently by Hitler and Stalin, with regard to the acquired, formerly Polish territories. The conferences were held by the Gestapo and the NKVD officials in several Polish cities. In spite of their differences on other issues, both Heinrich Himmler and Lavrentiy Beria had similar objectives as far as the fate of pre-war Poland was concerned. The objectives were agreed upon during signing of the German–Soviet Boundary and Friendship Treaty on 28 September 1939. The attack on Poland ended with the Nazi–Soviet parade in Brześć, which was held on 22 September 1939. Brześć was the location of the first Nazi-Soviet meeting organised on 27 September 1939, in which the prisoner exchange was decided prior to the signing of mutual agreements in Moscow a day later. In the following month, the Gestapo and the NKVD met in Lwów to discuss the fate of civilian populations during the radical reorganisation of the annexed territories. They met again in occupied Przemyśl at the end of November, because Przemyśl was a border crossing between the two invaders. The next series of meetings began in December 1939, a month after the first transfer of Polish prisoners of war. The conferences were held in occupied Kraków in the General Government on 6–7 December 1939; and continued for the next two days in the resort town of Zakopane in the Tatra Mountains of southern Poland (100 km from Kraków) on 8–9 December 1939. The Zakopane Conference is the most remembered. From the Soviet side, several higher officers of the NKVD secret police participated in the meetings, while the German hosts provided a group of experts from the Gestapo. Background After the signing of the Molotov–Ribbentrop Pact on 23 August 1939, Germany invaded Poland on 1 September 1939, and the Soviet Union invaded Poland on 17 September, resulting in the occupation of Poland by the Soviet Union and Nazi Germany. The first Gestapo–NKVD meeting took place in Brześć nad Bugiem (Brest) reportedly on 27 September 1939, while some units of the Polish Army were still fighting (see: Invasion of Poland) resulting in mass internment of soldiers and their extrajudicial shootings on both
