The Holocaust in the context of "Heinrich Himmler"

World War II or the Second World War (1 September 1939 – 2 September 1945) was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were put on trial for war crimes.

The causes of World War II included unresolved tensions in the aftermath of World War I, the rise of fascism in Europe and militarism in Japan. Key events preceding the war included Japan's invasion of Manchuria in 1931, the Spanish Civil War, the outbreak of the Second Sino-Japanese War in 1937, and Germany's annexations of Austria and the Sudetenland. World War II is generally considered to have begun on 1 September 1939, when Nazi Germany, under Adolf Hitler, invaded Poland, after which the United Kingdom and France declared war on Germany. Poland was divided between Germany and the Soviet Union under the Molotov–Ribbentrop Pact. In 1940, the Soviet Union annexed the Baltic states and parts of Finland and Romania. After the fall of France in June 1940, the war continued mainly between Germany, now assisted by Fascist Italy, and the British Empire, with fighting in the Balkans, Mediterranean, and Middle East, the aerial Battle of Britain and the Blitz, and the naval Battle of the Atlantic. Through campaigns and treaties, Germany gained control of much of continental Europe and formed the Axis alliance with Italy, Japan, and other countries. In June 1941, Germany invaded the Soviet Union, opening the Eastern Front and initially making large territorial gains.

Sigmund Freud (born Sigismund Schlomo Freud; 6 May 1856 – 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for evaluating and treating pathologies seen as originating from conflicts in the psyche, through dialogue between patient and psychoanalyst, and the distinctive theory of mind and human agency derived from it.

Freud was born to Galician Jewish parents in the Moravian town of Freiberg, in the Austrian Empire. He qualified as a doctor of medicine in 1881 at the University of Vienna. Upon completing his habilitation in 1885, he was appointed a docent in neuropathology and became an affiliated professor in 1902. Freud lived and worked in Vienna, having set up his clinical practice there in 1886. Following the German annexation of Austria in March 1938, Freud left Austria to escape Nazi persecution. He died in exile in the United Kingdom in September 1939.

Human rights are universally recognized moral principles or norms that establish standards of human behavior and are often protected by both national and international laws. These rights are considered inherent and inalienable, meaning they belong to every individual simply by virtue of being human, regardless of characteristics like nationality, ethnicity, religion, or socio-economic status. They encompass a broad range of civil, political, economic, social, and cultural rights, such as the right to life, freedom of expression, protection against enslavement, and right to education.

While ideas related to human rights predate modernity, the modern concept of human rights gained significant prominence after World War II, particularly in response to the atrocities of the Holocaust, leading to the adoption of the Universal Declaration of Human Rights (UDHR) by the United Nations General Assembly in 1948. This document outlined a comprehensive framework of rights that countries are encouraged to protect, setting a global standard for human dignity, freedom, and justice. The Universal Declaration of Human Rights (UDHR) has since inspired numerous international treaties and national laws aimed at promoting and protecting human rights worldwide.

Religion in the Netherlands was dominated by Christianity between the 10th and 20th centuries. In the late 19th century, roughly 60% of the population was Calvinist and 35% was Catholic. Also, until The Holocaust, there was a noticeable Jewish minority. Since World War II, there has been a significant decline in Catholic and especially Protestant Christianity, with Protestantism declining to such a degree that Catholicism became the foremost form of the Christian religion. The majority of the Dutch population is secular; however, historic societal pillarisation (verzuiling) based on religious lines continue to influence parts of Dutch society. Relatively sizable Muslim and Hindu minorities also exist.

Adolf Hitler (20 April 1889 – 30 April 1945) was an Austrian-born German politician who was the dictator of Germany during the Nazi era, which lasted from 1933 until his suicide in 1945. He rose to power as the leader of the Nazi Party, becoming the chancellor of Germany in 1933 and then taking the title of Führer und Reichskanzler in 1934. Germany's invasion of Poland on 1 September 1939 under his leadership marked the outbreak of the Second World War. Throughout the ensuing conflict, Hitler was closely involved in the direction of German military operations as well as the perpetration of the Holocaust, the genocide of about six million Jews and millions of other victims.

Hitler was born in Braunau am Inn in Austria-Hungary and moved to Germany in 1913. He was decorated during his service in the German Army in the First World War, receiving the Iron Cross. In 1919, he joined the German Workers' Party (DAP), the precursor of the Nazi Party, and in 1921, was appointed the leader of the Nazi Party. In 1923, he attempted to seize governmental power in a failed coup in Munich and was sentenced to five years in prison, serving just over a year. While there, he dictated the first volume of his autobiography and political manifesto Mein Kampf (lit. 'My Struggle'). After his early release in 1924, he gained popular support by attacking the Treaty of Versailles as well as promoting pan-Germanism, antisemitism, and anti-communism with charismatic oratory and Nazi propaganda. He frequently denounced communism as being part of an international Jewish conspiracy. By November 1932, the Nazi Party held the most seats in the Reichstag, but not a majority. Former chancellor Franz von Papen and other conservative politicians convinced President Paul von Hindenburg to appoint Hitler as chancellor on 30 January 1933. Shortly thereafter on 23 March, the Reichstag passed the Enabling Act of 1933, which ultimately began the Weimar Republic's transformation into Nazi Germany.

The invasion of Poland, also known as the September Campaign, Polish Campaign, and Polish Defensive War of 1939 (1 September – 6 October 1939), was a joint attack on the Republic of Poland by Nazi Germany, the Slovak Republic, and the Soviet Union, which marked the beginning of World War II. The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and the Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact. The Soviets invaded Poland on 17 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German–Soviet Frontier Treaty.

The aim of the invasion was to disestablish Poland as a sovereign country, with its citizens destined for extermination. German and Slovak forces invaded Poland from the north, south, and west the morning after the Gleiwitz incident. As the Wehrmacht advanced, Polish forces withdrew from their forward bases of operation close to the Germany–Poland border to more established defense lines to the east. After the mid-September Polish defeat in the Battle of the Bzura, the Germans gained an undisputed advantage. Polish forces then withdrew to the southeast where they prepared for a long defence of the Romanian Bridgehead and awaited expected support and relief from France and the United Kingdom. On 3 September, based on their alliance agreements with Poland, the United Kingdom and France declared war on Germany; in the end their aid to Poland was very limited. France invaded a small part of Germany in the Saar Offensive, and the Polish army was effectively defeated even before the British Expeditionary Force could be transported to continental Europe.

Operation Barbarossa was the invasion of the Soviet Union by Nazi Germany and several of its European Axis allies starting on Sunday, 22 June 1941, during World War II. More than 3.8 million Axis troops invaded the western Soviet Union along a 2,900-kilometer (1,800 mi) front, with the main goal of capturing territory up to a line between Arkhangelsk and Astrakhan, known as the A–A line. The attack became the largest and costliest military offensive in human history, with around 10 million combatants taking part in the opening phase and over 8 million casualties by the end of the operation on 5 December 1941. It marked a major escalation of World War II, opened the Eastern Front—the largest and deadliest land war in history—and brought the Soviet Union into the Allied powers.

The operation, code-named after the Holy Roman Emperor Frederick Barbarossa ("red beard"), put into action Nazi Germany's ideological goals of eradicating communism and conquering the western Soviet Union to repopulate it with Germans under Generalplan Ost, which planned for the removal of the native Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. The material targets of the invasion were the agricultural and mineral resources of territories such as Ukraine and Byelorussia and oil fields in the Caucasus. The Axis eventually captured five million Soviet Red Army troops on the Eastern Front and deliberately starved to death or otherwise killed 3.3 million prisoners of war, as well as millions of civilians. Mass shootings and gassing operations, carried out by German paramilitary death squads and collaborators, murdered over a million Soviet Jews as part of the Holocaust.

Ernst Kaltenbrunner (4 October 1903 – 16 October 1946) was an Austrian high-ranking SS official during the Nazi era, major perpetrator of the Holocaust and convicted war criminal. After the assassination of Reinhard Heydrich in 1942, and a brief period under Heinrich Himmler, Kaltenbrunner was the third Chief of the Reich Security Main Office (RSHA), which included the offices of Gestapo, Kripo and SD, from January 1943 until the end of World War II in Europe.

Kaltenbrunner joined the Nazi Party in 1930 and the SS in 1931, and by 1935 he was considered a leader of the Austrian SS. In 1938, he assisted in the Anschluss and was given command of the SS and police force in Austria. In January 1943, Kaltenbrunner was appointed chief of the RSHA, succeeding Reinhard Heydrich, who was assassinated in May 1942.
