German Reich in the context of "Reich"

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 German Empire (German: Deutsches Reich), also referred to as Imperial Germany, the Second Reich, or simply Germany, was the period of the German Reich from the unification of Germany in 1871 until the November Revolution in 1918, when Germany changed its form of government to a republic. The German Empire consisted of 25 states, each with its own nobility: four constituent kingdoms, six grand duchies, five duchies (six before 1876), seven principalities, three free Hanseatic cities, and one imperial territory. While Prussia was only one of the four kingdoms in the realm, it contained about two-thirds of the Empire's population and territory, and Prussian dominance was also constitutionally established, since the King of Prussia was also the German Emperor (Deutscher Kaiser).

The empire was founded on 18 January 1871, when the south German states, except for Austria, Switzerland and Liechtenstein, joined the North German Confederation. The new constitution came into force on 16 April, changing the name of the federal state to the German Empire and introducing the title of German Emperor for Wilhelm I, King of Prussia from the House of Hohenzollern. Berlin remained its capital, and Otto von Bismarck, Minister President of Prussia, became chancellor, the head of government. After 1850, the states of Germany had rapidly become industrialized. In 1871, Germany had a population of 41 million people; by 1913, this had increased to 68 million. A heavily rural collection of states in 1815, the now united Germany became predominantly urban. German factories were often larger and more modern than many of their British and French counterparts, but the preindustrial sector was more backward. The success of the German Empire in the natural sciences was such that one-third of all Nobel Prizes went to German inventors and researchers. During its 47 years of existence, the German Empire became an industrial, technological, and scientific power in Europe, and by 1913, Germany was the largest economy in continental Europe and the third largest in the world. Germany also became a great power, building the longest railway network of Europe, the world's strongest army, and a fast-growing industrial base. Starting very small in 1871, in a decade, the navy became second only to Britain's Royal Navy.

East Germany, officially the German Democratic Republic (GDR), was a country in Central Europe from its formation on 7 October 1949 until its reunification with West Germany (Federal Republic of Germany) on 3 October 1990. Until 1989, it was generally viewed as a communist state and described itself as a socialist workers' and peasants' state. The economy of the country was centrally planned and state-owned. Although the GDR had to pay substantial war reparations to the Soviet Union, its economy became the most successful in the Eastern Bloc.

Before its establishment, the country's territory was administered and occupied by Soviet forces following the Berlin Declaration abolishing German sovereignty in World War II. The Potsdam Agreement established the Soviet-occupied zone, bounded on the east by the Oder–Neiße line. The GDR was dominated by the Socialist Unity Party of Germany (SED), a communist party, before being democratized and liberalized amid the revolutions of 1989; this paved the way for East Germany's reunification with West Germany. Unlike the government of West Germany, the SED did not see its state as the successor to the German Reich (1871–1945). In 1974, it abolished the goal of unification in the constitution. The SED-ruled GDR was often described as a Soviet satellite state; historians describe it as an authoritarian regime.

West Germany was the common English name for the Federal Republic of Germany (FRG) from its formation on 23 May 1949 until its reunification with East Germany on 3 October 1990. It was sometimes known as the Bonn Republic after its capital city of Bonn, or as the Second German Republic. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from twelve states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France.

At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as the sole democratically reorganised continuation of the 1871–1945 German Reich.

The Unification of Germany (German: Deutsche Einigung, pronounced [ˈdɔʏtʃə ˈʔaɪnɪɡʊŋ] ) was a process of building the first nation-state for Germans with federal features based on the concept of Lesser Germany (one without the Habsburgs' multi-ethnic Austria or its German-speaking part). After the deletion of the German Confederation due to the Austro-Prussian War, it commenced on 18 August 1866 with the adoption of the North German Confederation Treaty establishing the North German Confederation, initially a military alliance de facto dominated by the Kingdom of Prussia which was subsequently deepened through adoption of the North German Constitution.

The process symbolically concluded when most of the south German states joined the North German Confederation with the ceremonial proclamation of the German Empire (German Reich) having 25 member states and led by the Kingdom of Prussia of Hohenzollerns on 18 January 1871; the event was typically celebrated as the date of the German Empire's foundation, although the legally meaningful events relevant to the completion of unification occurred on 1 January 1871 (accession of South German states and constitutional adoption of the name "German Empire"), 4 May 1871 (entry into force of the permanent Constitution of the German Empire) and 10 May 1871 (Treaty of Frankfurt and recognition of the Empire by the French Third Republic).

The Reich Security Main Office (German: Reichssicherheitshauptamt pronounced [ˈʁaɪ̯çsˌzɪçɐhaɪ̯t͡sˌhaʊ̯ptʔamt] , RSHA) was an organization under Heinrich Himmler in his dual capacity as Chef der Deutschen Polizei (Chief of German Police) and Reichsführer-SS, the head of the Nazi Party's Schutzstaffel (SS). The organization's stated duty was to fight all "enemies of the Reich" inside and outside the borders of Nazi Germany. From its very inception, the RSHA was a central institution for the Nazis, playing a pivotal role in orchestrating and executing the Holocaust.
