Generalplan Ost in the context of "Operation Barbarossa"

Lebensraum (German pronunciation: [ˈleːbənsˌʁaʊm] , lit. 'living space') is a German concept of expansionism and Völkisch nationalism, the philosophy and policies of which were common to German politics from the 1890s to the 1940s. First popularized around 1901, Lebensraum became a geopolitical goal of the German Empire in World War I (1914–1918), as the core element of the Septemberprogramm of territorial expansion. The most extreme form of this ideology was promoted and initiated by the Nazi Party, that had ruled Nazi Germany, whose ultimate goal of which was to establish a Greater German Reich. Lebensraum was a leading motivation of Nazi Germany to initiate World War II, and it would continue this policy until the end of the conflict.

Following Adolf Hitler's rise to power, Lebensraum became an ideological principle of Nazism and provided justification for the German territorial expansion into Central and Eastern Europe. The Nazi policy Generalplan Ost (lit. 'Master Plan for the East') was based on its tenets. It stipulated that Germany required a Lebensraum necessary for its survival and that most of the populations of Central and Eastern Europe would have to be removed permanently (either through mass deportation to Siberia, extermination, or enslavement), including Polish, Ukrainian, Russian, Belarusian, Czech, and other Slavic nations considered non-Aryan. The Nazi government aimed at repopulating these lands with Germanic colonists in the name of Lebensraum during and following World War II. Entire populations were ravaged by starvation; any agricultural surplus was used to feed Germany. The Jewish population was to be exterminated outright.

The destruction of Warsaw was Nazi Germany's razing of the city in late 1944, after the 1944 Warsaw Uprising of the Polish resistance. The uprising infuriated German leaders, who decided to destroy the city in retaliation.

The razing of the city had long been planned. Warsaw had been selected for destruction and major reconstruction as part of the Nazis' planned Germanization of Central Europe, under the Nazi Generalplan Ost. However, by late 1944, with the war clearly lost, the Germans had abandoned their plans of colonizing the East. Thus, the destruction of Warsaw did not serve any military or colonial purpose; it was carried out solely as an act of reprisal.

The military occupation of Latvia by Nazi Germany was completed on 10 July 1941, by Germany's armed forces. Initially, the territory of Latvia was under the military administration of Army Group North, but on 25 July 1941, Latvia was incorporated as Generalbezirk Lettland, subordinated to Reichskommissariat Ostland, an administrative subdivision of Nazi Germany. Anyone not racially acceptable or who opposed the German occupation, as well as those who had cooperated with the Soviet Union, was killed or sent to concentration camps in accordance with the Nazi Generalplan Ost.

The Reich Ministry for the Occupied Eastern Territories (RMfdbO; German: Reichsministerium für die besetzten Ostgebiete), commonly known as the Ostministerium, (pronounced [ˈɔstminɪsˌteːʁiʊm] ; "Eastern Ministry") was a ministry of Nazi Germany responsible for occupied territories in the Baltic states and Soviet Union from 1941 to 1945. Alfred Rosenbergserved as Reichsminister with Alfred Meyer as his deputy during its existence.

The Ostministerium was created by Adolf Hitler shortly after the German invasion of the Soviet Union to control the vast areas captured and projected for capture by the Wehrmacht in the Baltic states, Belarus, Ukraine, and Russia. Two Reichskommissariats were established: Ostland and Ukraine, while two more were planned, Moskowien and Kaukasien, but the Wehrmacht never established firm possession of the areas designated and German civilian control never developed there. The Ostministerium was involved in the development and implementation of Generalplan Ost, which fell under its jurisdiction, along with the Reich Commission for the Consolidation of German Nationhood, the Reich Security Main Office, and the SS Race and Settlement Main Office. It was one of the main agencies that oversaw the Holocaust in the Soviet Union.

Anti-Slavic sentiment, also called anti-Slavic racism or Slavophobia, refers to different types of negative attitudes, prejudices, collective hatred or animosity, stereotypes, discrimination, and violence (economic, physical, political, psychological, verbal, etc.) directed at one or more ethnic groups of Slavic peoples. Accompanying racism and xenophobia, the most common manifestation of anti-Slavic sentiment throughout history has been the assertion that some Slavs are inferior to other peoples.

Anti-Slavic sentiment reached its highest point during World War II, when Nazi Germany and its collaborators classified most of the Slavs, especially the Belarusians, Croats, Czechs, Poles, Russians, Serbs, Slovenes, and Ukrainians, as "subhumans" (Untermenschen) and perpetrated a systematic genocide against them, murdering millions of Slavs through the Generalplan Ost and Hunger Plan.
