Anschluss in the context of "Sigmund Freud"

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.

Nazi Germany, officially the German Reich and later the Greater German Reich, was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a totalitarian dictatorship. The Third Reich, meaning "Third Realm" or "Third Empire", referred to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which the Nazis referred to as the Thousand-Year Reich, ended in May 1945, after 12 years, when the Allies defeated Germany and entered the capital, Berlin, ending World War II in Europe.

After Hitler was appointed Chancellor of Germany in 1933, the Nazi Party began to eliminate political opposition and consolidate power. A 1934 German referendum confirmed Hitler as sole Führer (leader). Power was centralised in Hitler's person, and his word became the highest law. The government was not a co-ordinated, cooperating body, but rather a collection of factions struggling to amass power. To address the Great Depression, the Nazis used heavy military spending, extensive public works projects, including the Autobahnen (motorways) and a massive secret rearmament program, forming the Wehrmacht (armed forces), all financed by deficit spending. The return to economic stability and end of mass unemployment boosted the regime's popularity. Hitler made increasingly aggressive territorial demands, seizing Austria in the Anschluss of 1938, and the Sudetenland region of Czechoslovakia. Germany signed a non-aggression pact with the Soviet Union and invaded Poland in 1939, launching World War II in Europe. In alliance with Fascist Italy and other Axis powers, Germany conquered most of Europe by 1940 and threatened Britain.

The entirety of Germany was occupied and administered by the Allies of World War II, from the Berlin Declaration on 5 June 1945 to the establishment of West Germany on 23 May 1949. Unlike occupied Japan, Nazi Germany was stripped of its sovereignty and its government was entirely dissolved. After Germany formally surrendered on Tuesday, 8 May 1945, the four countries representing the Allies (the United States, United Kingdom, Soviet Union, and France) asserted joint authority and sovereignty through the Allied Control Council (ACC).

Germany after the war was a devastated country – roughly 80 percent of its infrastructure was in need of repair or reconstruction – which helped the idea that Germany was entering a new phase of history ("zero hour"). At first, Allied-occupied Germany was defined as all territories of Germany before the 1938 Nazi annexation of Austria. The Potsdam Agreement on 2 August 1945 defined the new eastern German border by giving Poland and the Soviet Union all regions of Germany east of the Oder–Neisse line (eastern parts of Pomerania, Neumark, Posen-West Prussia, East-Prussia and most of Silesia) and divided the remaining "Germany as a whole" into four occupation zones, each administered by one of the Allies.

At the end of World War II in Europe, Austria was occupied by the Allies and declared independence from Nazi Germany on 27 April 1945 (confirmed by the Berlin Declaration for Germany on 5 June 1945), as a result of the Vienna offensive. The occupation ended when the Austrian State Treaty came into force on 27 July 1955.

After the Anschluss in 1938, Austria had generally been recognized as part of Nazi Germany. In November 1943, however, the Allies agreed in the Declaration of Moscow that Austria would instead be regarded as the first victim of Nazi aggression—without denying Austria's role in Nazi crimes—and treated as a liberated and independent country after the war.

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.

German Reich (lit. 'German Empire' or 'German Realm', from German: Deutsches Reich) was the constitutional name for the German nation state that existed from 1871 to 1945. The Reich became understood as deriving its authority and sovereignty entirely from a continuing unitary German Volk ("national people"), with that authority and sovereignty being exercised at any one time over a unitary German "state territory" with variable boundaries and extent. Although commonly translated as "German Empire", the word Reich here better translates as "realm" or territorial "reach", in that the term does not in itself have monarchical connotations.

The name "German Reich" was officially proclaimed on 18 January 1871 at the Palace of Versailles by Otto von Bismarck and Wilhelm I of Prussia. After the annexation of Austria to Germany on 12–13 March 1938, the name "Greater German Reich" (German: Großdeutsches Reich) began to be used along with the official name "German Reich". According to the decree of the Chief of the Reich Chancellery Hans Lammers of 26 June 1943, the name "Greater German Reich" became mandatory in official documents.

The Reichsautobahn system was the beginning of the German autobahns under Nazi Germany. There had been previous plans for controlled-access highways in Germany under the Weimar Republic, and two had been constructed, but work had yet to start on long-distance highways. After previously opposing plans for a highway network, the Nazis embraced them after coming to power and presented the project as Hitler's own idea. They were termed "The Fuehrer's roads" ("German: Straßen des Führers") and presented as a major contribution to the reduction of unemployment. Other reasons for the project included enabling Germans to explore and appreciate their country, and there was a strong aesthetic element to the execution of the project under the Third Reich; military applications, although to a lesser extent than has often been thought; a permanent monument to the Third Reich, often compared to the pyramids; and general promotion of motoring as a modernization that in itself had military applications.

Hitler turned the first sod on 23 September 1933, at Frankfurt, and work officially began simultaneously at multiple sites throughout the Reich the following spring. The first finished stretch, between Frankfurt and Darmstadt, opened on 19 May 1935, and the first 1,000 km (620 mi) were completed on 23 September 1936. After the annexation of Austria, the planned network was expanded to include the Ostmark, and a second soil-breaking ceremony for the first Reichsautobahn on formerly Austrian territory took place near Salzburg on 7 April 1938. When work ceased in 1941 because of World War II, 3,819.7 km (2,373.5 mi) had been completed.
