Polish Committee of National LiberationThe Polish Committee of National Liberation (Polish: Polski Komitet Wyzwolenia Narodowego, PKWN), also known as the Lublin Committee, was an executive governing authority established by the Soviet-backed communists in Poland at the later stage of World War II. It was officially proclaimed on 22 July 1944 in Chełm, installed on 26 July in Lublin and placed formally under the direction of the State National Council (Krajowa Rada Narodowa, KRN).
AbwehrThe Abwehr (German for resistance or defence, though the word usually means counterintelligence in a military context; ˈapveːɐ̯) was the German military-intelligence service for the Reichswehr and the Wehrmacht from 1920 to 1945. Although the 1919 Treaty of Versailles prohibited the Weimar Republic from establishing an intelligence organization of their own, they formed an espionage group in 1920 within the Ministry of Defence, calling it the Abwehr.
IntelligenzaktionThe Intelligenzaktion (ɪntɛliˈɡɛnt͡s.akˌt͡sjoːn), or the Intelligentsia mass shootings, was a series of mass murders which was committed against the Polish intelligentsia (teachers, priests, physicians, and other prominent members of Polish society) early in the Second World War (1939–45) by Nazi Germany. The Germans conducted the operations in accordance with their plan to Germanize the western regions of occupied Poland, before their territorial annexation to the German Reich.
Mass killings under communist regimesMass killings under communist regimes occurred through a variety of means during the 20th century, including executions, famine, deaths through forced labour, deportation, starvation, and imprisonment. Some of these events have been classified as genocides or crimes against humanity. Other terms have been used to describe these events, including classicide, democide, red holocaust, and politicide. The mass killings have been studied by authors and academics and several of them have postulated the potential causes of these killings along with the factors which were associated with them.
KaliningradKaliningrad (kəˈlɪnᵻnɡræd ; Калининград), until 1946 known as Königsberg (ˈkøːnɪçsbɛʁk; Kyonigsberg; Królewiec), is the largest city and administrative centre of Kaliningrad Oblast, a Russian exclave between Lithuania and Poland. The city sits about west from mainland Russia. The city is situated on the Pregolya River, at the head of the Vistula Lagoon on the Baltic Sea, and is the only ice-free port of Russia and the Baltic states on the Baltic Sea. Its population in 2020 was 489,359, with up to 800,000 residents in the urban agglomeration.
Population transfer in the Soviet UnionFrom 1930 to 1952, the government of the Soviet Union, on the orders of Soviet leader Joseph Stalin under the direction of the NKVD official Lavrentiy Beria, forcibly transferred populations of various groups. These actions may be classified into the following broad categories: deportations of "anti-Soviet" categories of population (often classified as "enemies of the people"), deportations of entire nationalities, labor force transfer, and organized migrations in opposite directions to fill ethnically cleansed territories.
Polish government-in-exileThe Polish government-in-exile, officially known as the Government of the Republic of Poland in exile (Rząd Rzeczypospolitej Polskiej na uchodźstwie), was the government in exile of Poland formed in the aftermath of the Invasion of Poland of September 1939, and the subsequent occupation of Poland by Germany, the Soviet Union, and the Slovak Republic, which brought to an end the Second Polish Republic.
Court-martialA court-martial or court martial (plural courts-martial or courts martial, as "martial" is a postpositive adjective) is a military court or a trial conducted in such a court. A court-martial is empowered to determine the guilt of members of the armed forces subject to military law, and, if the defendant is found guilty, to decide upon punishment. In addition, courts-martial may be used to try prisoners of war for war crimes. The Geneva Conventions require that POWs who are on trial for war crimes be subject to the same procedures as would be the holding military's own forces.
IntelligentsiaThe intelligentsia is a status class composed of the university-educated people of a society who engage in the complex mental labours by which they critique, shape, and lead in the politics, policies, and culture of their society; as such, the intelligentsia consists of scholars, academics, teachers, journalists, and literary writers. Conceptually, the intelligentsia status class arose in the late 18th century, during the Partitions of Poland (1772–1795).
Vinnytsia massacreThe Vinnytsia massacre was the mass execution of between 9,000 and 11,000 people in the Ukrainian town of Vinnytsia by the Soviet secret police NKVD during the Great Purge in 1937–1938, which Nazi Germany discovered during its occupation of Ukraine in 1943. The investigation of the site first conducted by the international Katyn Commission coincided with the discovery of a similar mass murder site of Polish prisoners of war in Katyn. Nazi propaganda invoked mention of the massacre to illustrate communist terror by the Soviet Union.
