The third reich

Background
Germany was known as the Weimar Republic during the years 1919 to 1933. It was a republic with a semi-presidential system. The Weimar Republic faced numerous problems, including hyperinflation, political extremism (including violence from left- and right-wing paramilitaries), contentious relationships with the Allied victors of World War I, and a series of failed attempts at coalition government by divided political parties. Severe setbacks to the German economy began after World War I ended, partly because of reparations payments required under the 1919 Treaty of Versailles. The government printed money to make the payments and to repay the country's war debt, but the resulting hyperinflation led to inflated prices for consumer goods, economic chaos, and food riots. When the government defaulted on their reparations payments in January 1923, French troops occupied German industrial areas along the Ruhr and widespread civil unrest followed.

The National Socialist German Workers' Party (Nationalsozialistische Deutsche Arbeiterpartei), commonly known as the Nazi Party, was founded in 1920. It was the renamed successor of the German Workers' Party (DAP) formed one year earlier, and one of several far-right political parties then active in Germany. The Nazi Party platform included destruction of the Weimar Republic, rejection of the terms of the Treaty of Versailles, radical antisemitism, and anti-Bolshevism. They promised a strong central government, increased Lebensraum ("living space") for Germanic peoples, formation of a national community based on race, and racial cleansing via the active suppression of Jews, who would be stripped of their citizenship and civil rights. The Nazis proposed national and cultural renewal based upon the Völkisch movement. The party, especially its paramilitary organisation Sturmabteilung (SA; Storm Detachment), or Brownshirts, used physical violence to advance their political position, disrupting the meetings of rival organisations and attacking their members as well as Jewish people on the streets. Such far-right armed groups were common in Bavaria, and were tolerated by the sympathetic far-right state government of Gustav Ritter von Kahr.

When the stock market in the United States crashed on 24 October 1929, the effect in Germany was dire. Millions were thrown out of work and several major banks collapsed. Hitler and the Nazis prepared to take advantage of the emergency to gain support for their party. They promised to strengthen the economy and provide jobs. Many voters decided the Nazi Party was capable of restoring order, quelling civil unrest, and improving Germany's international reputation. After the federal election of 1932, the party was the largest in the Reichstag, holding 230 seats with 37.4 per cent of the popular vote.

Nazi seizure of power
Although the Nazis won the greatest share of the popular vote in the two Reichstag general elections of 1932, they did not have a majority. Hitler therefore led a short-lived coalition government formed with the German National People's Party. Under pressure from politicians, industrialists, and the business community, President Paul von Hindenburg appointed Hitler as Chancellor of Germany on 30 January 1933. This event is known as the Machtergreifung ("seizure of power").

On the night of 27 February 1933, the Reichstag building was set afire. Marinus van der Lubbe, a Dutch communist, was found guilty of starting the blaze. Hitler proclaimed that the arson marked the start of a communist uprising. The Reichstag Fire Decree, imposed on 28 February 1933, rescinded most civil liberties, including rights of assembly and freedom of the press. The decree also allowed the police to detain people indefinitely without charges. The legislation was accompanied by a propaganda campaign that led to public support for the measure. Violent suppression of communists by the SA was undertaken nationwide and 4,000 members of the Communist Party of Germany were arrested.

In March 1933, the Enabling Act, an amendment to the Weimar Constitution, passed in the Reichstag by a vote of 444 to 94. This amendment allowed Hitler and his cabinet to pass laws—even laws that violated the constitution—without the consent of the president or the Reichstag. As the bill required a two-thirds majority to pass, the Nazis used intimidation tactics as well as the provisions of the Reichstag Fire Decree to keep several Social Democratic deputies from attending, and the Communists had already been banned. On 10 May, the government seized the assets of the Social Democrats, and they were banned on 22 June. On 21 June, the SA raided the offices of the German National People's Party – their former coalition partners – which then disbanded on 29 June. The remaining major political parties followed suit. On 14 July 1933 Germany became a one-party state with the passage of a law decreeing the Nazi Party to be the sole legal party in Germany. The founding of new parties was also made illegal, and all remaining political parties which had not already been dissolved were banned. The Enabling Act would subsequently serve as the legal foundation for the dictatorship the Nazis established. Further elections in November 1933, 1936, and 1938 were Nazi-controlled, with only members of the Party and a small number of independents elected.

Nazification of Germany
While the traditional German states were not formally abolished (excluding Lübeck in 1937), their constitutional rights and sovereignty were eroded and ultimately ended. Prussia was already under federal administration when Hitler came to power, providing a model for the process. The Hitler cabinet used the terms of the Reichstag Fire Decree and later the Enabling Act to initiate the process of Gleichschaltung ("co-ordination"), which brought all aspects of life under party control. Individual states not controlled by elected Nazi governments or Nazi-led coalitions were forced to agree to the appointment of Reich Commissars to bring the states in line with the policies of the central government. These Commissars had the power to appoint and remove local governments, state parliaments, officials, and judges. In this way Germany became a de facto unitary state, with all state governments controlled by the central government under the Nazis. The state parliaments and the Reichsrat (federal upper house) were abolished in January 1934, with all state powers being transferred to the central government.

All civilian organisations, including agricultural groups, volunteer organisations, and sports clubs, had their leadership replaced with Nazi sympathisers or party members; these civic organisations either merged with the Nazi Party or faced dissolution. The Nazi government declared a "Day of National Labor" for May Day 1933, and invited many trade union delegates to Berlin for celebrations. The day after, SA stormtroopers demolished union offices around the country; all trade unions were forced to dissolve and their leaders were arrested. The Law for the Restoration of the Professional Civil Service, passed in April, removed from their jobs all teachers, professors, judges, magistrates, and government officials who were Jewish or whose commitment to the party was suspect. This meant the only non-political institutions not under control of the Nazis were the churches.

The Nazi regime abolished the symbols of the Weimar Republic—including the black, red, and gold tricolour flag—and adopted reworked symbolism. The previous imperial black, white, and red tricolour was restored as one of Germany's two official flags; the second was the swastika flag of the Nazi Party, which became the sole national flag in 1935. The Party anthem "Horst-Wessel-Lied" ("Horst Wessel Song") became a second national anthem.

Germany was still in a dire economic situation, as six million people were unemployed and the balance of trade deficit was daunting. Using deficit spending, public works projects were undertaken beginning in 1934, creating 1.7 million new jobs by the end of that year alone. Average wages began to rise.

Consolidation of power
The SA leadership continued to apply pressure for greater political and military power. In response, Hitler used the Schutzstaffel (SS) and Gestapo to purge the entire SA leadership. Hitler targeted SA Stabschef (Chief of Staff) Ernst Röhm and other SA leaders who—along with a number of Hitler's political adversaries (such as Gregor Strasser and former chancellor Kurt von Schleicher)—were arrested and shot. Up to 200 people were killed from 30 June to 2 July 1934 in an event that became known as the Night of the Long Knives.

On 2 August 1934, Hindenburg died. The previous day, the cabinet had enacted the "Law Concerning the Highest State Office of the Reich", which stated that upon Hindenburg's death the office of president would be abolished and its powers merged with those of the chancellor. Hitler thus became head of state as well as head of government and was formally named as Führer und Reichskanzler ("Leader and Chancellor"), although eventually Reichskanzler was dropped. Germany was now a totalitarian state with Hitler at its head. As head of state, Hitler became Supreme Commander of the armed forces. The new law provided an altered loyalty oath for servicemen so that they affirmed loyalty to Hitler personally rather than the office of supreme commander or the state. On 19 August, the merger of the presidency with the chancellorship was approved by 90 per cent of the electorate in a plebiscite.

Most Germans were relieved that the conflicts and street fighting of the Weimar era had ended. They were deluged with propaganda orchestrated by Minister of Public Enlightenment and Propaganda Joseph Goebbels, who promised peace and plenty for all in a united, Marxist-free country without the constraints of the Versailles Treaty. The Nazi Party obtained and legitimised power through its initial revolutionary activities, then through manipulation of legal mechanisms, the use of police powers, and by taking control of the state and federal institutions. The first major Nazi concentration camp, initially for political prisoners, was opened at Dachau in 1933. Hundreds of camps of varying size and function were created by the end of the war.

Beginning in April 1933, scores of measures defining the status of Jews and their rights were instituted. These measures culminated in the establishment of the Nuremberg Laws of 1935, which stripped them of their basic rights. The Nazis would take from the Jews their wealth, their right to intermarry with non-Jews, and their right to occupy many fields of labour (such as law, medicine, or education). Eventually the Nazis declared the Jews as undesirable to remain among German citizens and society.

Military build-up
In the early years of the regime, Germany was without allies, and its military was drastically weakened by the Versailles Treaty. France, Poland, Italy, and the Soviet Union each had reasons to object to Hitler's rise to power. Poland suggested to France that the two nations engage in a preventive war against Germany in March 1933. Fascist Italy objected to German claims in the Balkans and on Austria, which Benito Mussolini considered to be in Italy's sphere of influence.

As early as February 1933, Hitler announced that rearmament must begin, albeit clandestinely at first, as to do so was in violation of the Versailles Treaty. On 17 May 1933, Hitler gave a speech before the Reichstag outlining his desire for world peace and accepted an offer from American President Franklin D. Roosevelt for military disarmament, provided the other nations of Europe did the same. When the other European powers failed to accept this offer, Hitler pulled Germany out of the World Disarmament Conference and the League of Nations in October, claiming its disarmament clauses were unfair if they applied only to Germany. In a referendum held in November, 95 per cent of voters supported Germany's withdrawal.

In 1934, Hitler told his military leaders that a war in the east should begin in 1942. The Saarland, which had been placed under League of Nations supervision for 15 years at the end of World War I, voted in January 1935 to become part of Germany. In March 1935, Hitler announced the creation of an air force, and that the Reichswehr would be increased to 550,000 men. Britain agreed to Germany building a naval fleet with the signing of the Anglo-German Naval Agreement on 18 June 1935.

When the Italian invasion of Ethiopia led to only mild protests by the British and French governments, on 7 March 1936 Hitler used the Franco-Soviet Treaty of Mutual Assistance as a pretext to order the army to march 3,000 troops into the demilitarised zone in the Rhineland in violation of the Versailles Treaty. As the territory was part of Germany, the British and French governments did not feel that attempting to enforce the treaty was worth the risk of war. In the one-party election held on 29 March, the Nazis received 98.9 per cent support. In 1936, Hitler signed an Anti-Comintern Pact with Japan and a non-aggression agreement with Mussolini, who was soon referring to a "Rome-Berlin Axis".

Hitler sent military supplies and assistance to the Nationalist forces of General Francisco Franco in the Spanish Civil War, which began in July 1936. The German Condor Legion included a range of aircraft and their crews, as well as a tank contingent. The aircraft of the Legion destroyed the city of Guernica in 1937. The Nationalists were victorious in 1939 and became an informal ally of Nazi Germany.

Austria and Czechoslovakia
In February 1938, Hitler emphasised to Austrian Chancellor Kurt Schuschnigg the need for Germany to secure its frontiers. Schuschnigg scheduled a plebiscite regarding Austrian independence for 13 March, but Hitler sent an ultimatum to Schuschnigg on 11 March demanding that he hand over all power to the Austrian Nazi Party or face an invasion. German troops entered Austria the next day, to be greeted with enthusiasm by the populace.

The Republic of Czechoslovakia was home to a substantial minority of Germans, who lived mostly in the Sudetenland. Under pressure from separatist groups within the Sudeten German Party, the Czechoslovak government offered economic concessions to the region. Hitler decided not just to incorporate the Sudetenland into the Reich, but to destroy the country of Czechoslovakia entirely. The Nazis undertook a propaganda campaign to try to generate support for an invasion. Top German military leaders opposed the plan, as Germany was not yet ready for war.

The crisis led to war preparations by Britain, Czechoslovakia, and France (Czechoslovakia's ally). Attempting to avoid war, British Prime Minister Neville Chamberlain arranged a series of meetings, the result of which was the Munich Agreement, signed on 29 September 1938. The Czechoslovak government was forced to accept the Sudetenland's annexation into Germany. Chamberlain was greeted with cheers when he landed in London, saying the agreement brought "peace for our time". In addition to the German annexation, Poland seized a narrow strip of land near Cieszyn on 2 October, while as a consequence of the Munich Agreement, Hungary demanded and received 12,000 square kilometres (4,600 sq mi) along their northern border in the First Vienna Award on 2 November. Following negotiations with President Emil Hácha, Hitler seized the rest of the Czech half of the country on 15 March 1939 and created the Protectorate of Bohemia and Moravia, one day after the proclamation of the Slovak Republic in the Slovak half. Also on 15 March, Hungary occupied and annexed the recently proclaimed and unrecognised Carpatho-Ukraine and an additional sliver of land disputed with Slovakia.

Austrian and Czech foreign exchange reserves were seized by the Nazis, as were stockpiles of raw materials such as metals and completed goods such as weaponry and aircraft, which were shipped to Germany. The Reichswerke Hermann Göring industrial conglomerate took control of steel and coal production facilities in both countries.

Poland
In January 1934, Germany signed a non-aggression pact with Poland. In March 1939, Hitler demanded the return of the Free City of Danzig and the Polish Corridor, a strip of land that separated East Prussia from the rest of Germany. The British announced they would come to the aid of Poland if it was attacked. Hitler, believing the British would not actually take action, ordered an invasion plan should be readied for September 1939. On 23 May, Hitler described to his generals his overall plan of not only seizing the Polish Corridor but greatly expanding German territory eastward at the expense of Poland. He expected this time they would be met by force.

The Germans reaffirmed their alliance with Italy and signed non-aggression pacts with Denmark, Estonia, and Latvia whilst trade links were formalised with Romania, Norway, and Sweden. Foreign Minister Joachim von Ribbentrop arranged in negotiations with the Soviet Union a non-aggression pact, the Molotov–Ribbentrop Pact, signed in August 1939. The treaty also contained secret protocols dividing Poland and the Baltic states into German and Soviet spheres of influence.

Foreign policy
Germany's wartime foreign policy involved the creation of allied governments controlled directly or indirectly from Berlin. They intended to obtain soldiers from allies such as Italy and Hungary and workers and food supplies from allies such as Vichy France. Hungary was the fourth nation to join the Axis, signing the Tripartite Pact on 27 September 1940. Bulgaria signed the pact on 17 November. German efforts to secure oil included negotiating a supply from their new ally, Romania, who signed the Pact on 23 November, alongside the Slovak Republic. By late 1942, there were 24 divisions from Romania on the Eastern Front, 10 from Italy, and 10 from Hungary. Germany assumed full control in France in 1942, Italy in 1943, and Hungary in 1944. Although Japan was a powerful ally, the relationship was distant, with little co-ordination or co-operation. For example, Germany refused to share their formula for synthetic oil from coal until late in the war.

Outbreak of war
Germany invaded Poland and captured the Free City of Danzig on 1 September 1939, beginning World War II in Europe. Honouring their treaty obligations, Britain and France declared war on Germany two days later. Poland fell quickly, as the Soviet Union attacked from the east on 17 September. Reinhard Heydrich, chief of the Sicherheitspolizei (SiPo; Security Police) and Sicherheitsdienst (SD; Security Service), ordered on 21 September that Polish Jews should be rounded up and concentrated into cities with good rail links. Initially the intention was to deport them further east, or possibly to Madagascar. Using lists prepared in advance, some 65,000 Polish intelligentsia, noblemen, clergy, and teachers were murdered by the end of 1939 in an attempt to destroy Poland's identity as a nation. Soviet forces advanced into Finland in the Winter War, and German forces saw action at sea. But little other activity occurred until May, so the period became known as the "Phoney War".

From the start of the war, a British blockade on shipments to Germany affected its economy. Germany was particularly dependent on foreign supplies of oil, coal, and grain. Thanks to trade embargoes and the blockade, imports into Germany declined by 80 per cent. To safeguard Swedish iron ore shipments to Germany, Hitler ordered the invasion of Denmark and Norway, which began on 9 April. Denmark fell after less than a day, while most of Norway followed by the end of the month. By early June, Germany occupied all of Norway.

Conquest of Europe
Against the advice of many of his senior military officers, in May 1940 Hitler ordered an attack on France and the Low Countries. They quickly conquered Luxembourg and the Netherlands and outmanoeuvred the Allies in Belgium, forcing the evacuation of many British and French troops at Dunkirk. France fell as well, surrendering to Germany on 22 June. The victory in France resulted in an upswing in Hitler's popularity and an upsurge in war fever in Germany.

The Nazis seized from the French thousands of locomotives and rolling stock, stockpiles of weapons, and raw materials such as copper, tin, oil, and nickel. Payments for occupation costs were levied upon France, Belgium, and Norway. Barriers to trade led to hoarding, black markets, and uncertainty about the future. Food supplies were precarious; production dropped in most of Europe. Famine was experienced in many occupied countries.

Hitler's peace overtures to the new British Prime Minister Winston Churchill were rejected in July 1940. Grand Admiral Erich Raeder had advised Hitler in June that air superiority was a pre-condition for a successful invasion of Britain, so Hitler ordered a series of aerial attacks on Royal Air Force (RAF) airbases and radar stations, as well as nightly air raids on British cities, including London, Plymouth, and Coventry. The German Luftwaffe failed to defeat the RAF in what became known as the Battle of Britain, and by the end of October, Hitler realised that air superiority would not be achieved. He permanently postponed the invasion, a plan which the commanders of the German army had never taken entirely seriously. Several historians, including Andrew Gordon, believe the primary reason for the failure of the invasion plan was the superiority of the Royal Navy, not the actions of the RAF.

In February 1941, the German Afrika Korps arrived in Libya to aid the Italians in the North African Campaign. On 6 April, Germany launched an invasion of Yugoslavia and Greece. All of Yugoslavia and parts of Greece were subsequently divided between Germany, Hungary, Italy, and Bulgaria.

Invasion of the Soviet Union
On 22 June 1941, contravening the Molotov–Ribbentrop Pact, about 3.8 million Axis troops attacked the Soviet Union. In addition to Hitler's stated purpose of acquiring Lebensraum, this large-scale offensive—codenamed Operation Barbarossa—was intended to destroy the Soviet Union and seize its natural resources for subsequent aggression against the Western powers. The reaction among Germans was one of surprise and trepidation as many were concerned about how much longer the war would continue or suspected that Germany could not win a war fought on two fronts.

The invasion conquered a huge area, including the Baltic states, Belarus, and west Ukraine. After the successful Battle of Smolensk in September 1941, Hitler ordered Army Group Centre to halt its advance to Moscow and temporarily divert its Panzer groups to aid in the encirclement of Leningrad and Kyiv. This pause provided the Red Army with an opportunity to mobilise fresh reserves. The Moscow offensive, which resumed in October 1941, ended disastrously in December. On 7 December 1941, Japan attacked Pearl Harbor, Hawaii. Four days later, Germany declared war on the United States.

Food was in short supply in the conquered areas of the Soviet Union and Poland, as the retreating armies had burned the crops in some areas, and much of the remainder was sent back to the Reich. In Germany, rations were cut in 1942. In his role as Plenipotentiary of the Four Year Plan, Hermann Göring demanded increased shipments of grain from France and fish from Norway. The 1942 harvest was good, and food supplies remained adequate in Western Europe.

Germany and Europe as a whole were almost totally dependent on foreign oil imports. In an attempt to resolve the shortage, in June 1942 Germany launched Fall Blau ("Case Blue"), an offensive against the Caucasian oilfields. The Red Army launched a counter-offensive on 19 November and encircled the Axis forces, who were trapped in Stalingrad on 23 November. Göring assured Hitler that the 6th Army could be supplied by air, but this turned out to be infeasible. Hitler's refusal to allow a retreat led to the deaths of 200,000 German and Romanian soldiers; of the 91,000 men who surrendered in the city on 31 January 1943, only 6,000 survivors returned to Germany after the war.

Turning point and collapse
Losses continued to mount after Stalingrad, leading to a sharp reduction in the popularity of the Nazi Party and deteriorating morale. Soviet forces continued to push westward after the failed German offensive at the Battle of Kursk in the summer of 1943. By the end of 1943, the Germans had lost most of their eastern territorial gains. In Egypt, Field Marshal Erwin Rommel's Afrika Korps were defeated by British forces under Field Marshal Bernard Montgomery in October 1942. The Allies landed in Sicily in July 1943 and in Italy in September. Meanwhile, American and British bomber fleets based in Britain began operations against Germany. Many sorties were intentionally given civilian targets in an effort to destroy German morale. The bombing of aircraft factories as well as Peenemünde Army Research Center, where V-1 and V-2 rockets were being developed and produced, were also deemed particularly important. German aircraft production could not keep pace with losses, and without air cover the Allied bombing campaign became even more devastating. By targeting oil refineries and factories, they crippled the German war effort by late 1944.

On 6 June 1944, American, British, and Canadian forces established a front in France with the D-Day landings in Normandy. On 20 July 1944, Hitler survived an assassination attempt. He ordered brutal reprisals, resulting in 7,000 arrests and the execution of more than 4,900 people. The failed Ardennes Offensive (16 December 1944 – 25 January 1945) was the last major German offensive on the western front, and Soviet forces entered Germany on 27 January. Hitler's refusal to admit defeat and his insistence that the war be fought to the last man led to unnecessary death and destruction in the war's closing months. Through his Justice Minister Otto Georg Thierack, Hitler ordered that anyone who was not prepared to fight should be court-martialed, and thousands of people were executed. In many areas, people surrendered to the approaching Allies in spite of exhortations of local leaders to continue to fight. Hitler ordered the destruction of transport, bridges, industries, and other infrastructure—a scorched earth decree—but Armaments Minister Albert Speer prevented this order from being fully carried out.

During the Battle of Berlin (16 April 1945 – 2 May 1945), Hitler and his staff lived in the underground Führerbunker while the Red Army approached. On 30 April, when Soviet troops were within two blocks of the Reich Chancellery, Hitler, along with his girlfriend and by then wife Eva Braun committed suicide. On 2 May, General Helmuth Weidling unconditionally surrendered Berlin to Soviet General Vasily Chuikov. Hitler was succeeded by Grand Admiral Karl Dönitz as Reich President and Goebbels as Reich Chancellor. Goebbels and his wife Magda committed suicide the next day after murdering their six children. Between 4 and 8 May 1945, most of the remaining German armed forces unconditionally surrendered. The German Instrument of Surrender was signed 8 May, marking the end of the Nazi regime and the end of World War II in Europe.

Popular support for Hitler almost completely disappeared as the war drew to a close. Suicide rates in Germany increased, particularly in areas where the Red Army was advancing. Among soldiers and party personnel, suicide was often deemed an honourable and heroic alternative to surrender. First-hand accounts and propaganda about the uncivilised behaviour of the advancing Soviet troops caused panic among civilians on the Eastern Front, especially women, who feared being raped. More than a thousand people (out of a population of around 16,000) committed suicide in Demmin on and around 1 May 1945 as the 65th Army of 2nd Belorussian Front first broke into a distillery and then rampaged through the town, committing mass rapes, arbitrarily executing civilians, and setting fire to buildings. High numbers of suicides took place in many other locations, including Neubrandenburg (600 dead), Stolp in Pommern (1,000 dead), and Berlin, where at least 7,057 people committed suicide in 1945.

German casualties
Estimates of the total German war dead range from 5.5 to 6.9 million persons. A study by German historian Rüdiger Overmans puts the number of German military dead and missing at 5.3 million, including 900,000 men conscripted from outside of Germany's 1937 borders. Richard Overy estimated in 2014 that about 353,000 civilians were killed in Allied air raids. Other civilian deaths include 300,000 Germans (including Jews) who were victims of Nazi political, racial, and religious persecution and 200,000 who were murdered in the Nazi euthanasia program. Political courts called Sondergerichte sentenced some 12,000 members of the German resistance to death, and civil courts sentenced an additional 40,000 Germans. Mass rapes of German women also took place.

Territorial changes
As a result of their defeat in World War I and the resulting Treaty of Versailles, Germany lost Alsace-Lorraine, Northern Schleswig, and Memel. The Saarland became a protectorate of France under the condition that its residents would later decide by referendum which country to join, and Poland became a separate nation and was given access to the sea by the creation of the Polish Corridor, which separated Prussia from the rest of Germany, while Danzig was made a free city.

Germany regained control of the Saarland through a referendum held in 1935 and annexed Austria in the Anschluss of 1938. The Munich Agreement of 1938 gave Germany control of the Sudetenland, and they seized the remainder of Czechoslovakia six months later. Under threat of invasion by sea, Lithuania surrendered the Memel district in March 1939.

Between 1939 and 1941, German forces invaded Poland, Denmark, Norway, France, Luxembourg, the Netherlands, Belgium, Yugoslavia, Greece, and the Soviet Union. Germany annexed parts of northern Yugoslavia in April 1941, while Mussolini ceded Trieste, South Tyrol, and Istria to Germany in 1943.

Occupied territories
Some of the conquered territories were incorporated into Germany as part of Hitler's long-term goal of creating a Greater Germanic Reich. Several areas, such as Alsace-Lorraine, were placed under the authority of an adjacent Gau (regional district). The Reichskommissariate (Reich Commissariats), quasi-colonial regimes, were established in some occupied countries. Areas placed under German administration included the Protectorate of Bohemia and Moravia, Reichskommissariat Ostland (encompassing the Baltic states and Belarus), and Reichskommissariat Ukraine. Conquered areas of Belgium and France were placed under control of the Military Administration in Belgium and Northern France. Belgian Eupen-Malmedy, which had been part of Germany until 1919, was annexed. Part of Poland was incorporated into the Reich, and the General Government was established in occupied central Poland. The governments of Denmark, Norway (Reichskommissariat Norwegen), and the Netherlands (Reichskommissariat Niederlande) were placed under civilian administrations staffed largely by natives. Hitler intended to eventually incorporate many of these areas into the Reich. Germany occupied the Italian protectorate of Albania and the Italian governorate of Montenegro in 1943 and installed a puppet government in occupied Serbia in 1941.

Ideology
The Nazis were a far-right fascist political party which arose during the social and financial upheavals that occurred following the end of World War I. The Party remained small and marginalised, receiving 2.6% of the federal vote in 1928, prior to the onset of the Great Depression in 1929. By 1930 the Party won 18.3% of the federal vote, making it the Reichstag's second largest political party. While in prison after the failed Beer Hall Putsch of 1923, Hitler wrote Mein Kampf, which laid out his plan for transforming German society into one based on race. Nazi ideology brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum for the Germanic people. The regime attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or murder the Jews and Slavs living there, who were viewed as being inferior to the Aryan master race and part of a Jewish-Bolshevik conspiracy. The Nazi regime believed that only Germany could defeat the forces of Bolshevism and save humanity from world domination by International Jewry. Other people deemed life unworthy of life by the Nazis included the mentally and physically disabled, Romani people, homosexuals, Jehovah's Witnesses, and social misfits.

Influenced by the Völkisch movement, the regime was against cultural modernism and supported the development of an extensive military at the expense of intellectualism. Creativity and art were stifled, except where they could serve as propaganda media. The party used symbols such as the Blood Flag and rituals such as the Nazi Party rallies to foster unity and bolster the regime's popularity.

Government
Hitler ruled Germany autocratically by asserting the Führerprinzip ("leader principle"), which called for absolute obedience by all subordinates. He viewed the government structure as a pyramid, with himself—the infallible leader—at the apex. Party rank was not determined by elections, and positions were filled through appointment by those of higher rank. The party used propaganda to develop a cult of personality around Hitler. Historians such as Kershaw emphasise the psychological impact of Hitler's skill as an orator. Roger Gill states: "His moving speeches captured the minds and hearts of a vast number of the German people: he virtually hypnotized his audiences".

While top officials reported to Hitler and followed his policies, they had considerable autonomy. He expected officials to "work towards the Führer" – to take the initiative in promoting policies and actions in line with party goals and Hitler's wishes, without his involvement in day-to-day decision-making. The government was a disorganised collection of factions led by the party elite, who struggled to amass power and gain the Führer's favour. Hitler's leadership style was to give contradictory orders to his subordinates and to place them in positions where their duties and responsibilities overlapped. In this way he fostered distrust, competition, and infighting among his subordinates to consolidate and maximise his own power.

Successive Reichsstatthalter decrees between 1933 and 1935 abolished the existing Länder (constituent states) of Germany and replaced them with new administrative divisions, the Gaue, governed by Nazi leaders (Gauleiters). The change was never fully implemented, as the Länder were still used as administrative divisions for some government departments such as education. This led to a bureaucratic tangle of overlapping jurisdictions and responsibilities typical of the administrative style of the Nazi regime.

Jewish civil servants lost their jobs in 1933, except for those who had seen military service in World War I. Members of the Party or party supporters were appointed in their place. As part of the process of Gleichschaltung, the Reich Local Government Law of 1935 abolished local elections, and mayors were appointed by the Ministry of the Interior.

Law
In August 1934, civil servants and members of the military were required to swear an oath of unconditional obedience to Hitler. These laws became the basis of the Führerprinzip, the concept that Hitler's word overrode all existing laws. Any acts that were sanctioned by Hitler—even murder—thus became legal. All legislation proposed by cabinet ministers had to be approved by the office of Deputy Führer Rudolf Hess, who could also veto top civil service appointments.

Most of the judicial system and legal codes of the Weimar Republic remained in place to deal with non-political crimes. The courts issued and carried out far more death sentences than before the Nazis took power. People who were convicted of three or more offences—even petty ones—could be deemed habitual offenders and jailed indefinitely. People such as prostitutes and pickpockets were judged to be inherently criminal and a threat to the community. Thousands were arrested and confined indefinitely without trial.

A new type of court, the Volksgerichtshof ("People's Court"), was established in 1934 to deal with political cases. This court handed out over 5,000 death sentences until its dissolution in 1945. The death penalty could be issued for offences such as being a communist, printing seditious leaflets, or even making jokes about Hitler or other officials. The Gestapo was in charge of investigative policing to enforce Nazi ideology as they located and confined political offenders, Jews, and others deemed undesirable. Political offenders who were released from prison were often immediately re-arrested by the Gestapo and confined in a concentration camp.

The Nazis used propaganda to promulgate the concept of Rassenschande ("race defilement") to justify the need for racial laws. In September 1935, the Nuremberg Laws were enacted. These laws initially prohibited sexual relations and marriages between Aryans and Jews and were later extended to include "Gypsies, Negroes or their bastard offspring". The law also forbade the employment of German women under the age of 45 as domestic servants in Jewish households. The Reich Citizenship Law stated that only those of "German or related blood" could be citizens. Thus Jews and other non-Aryans were stripped of their German citizenship. The law also permitted the Nazis to deny citizenship to anyone who was not supportive enough of the regime. A supplementary decree issued in November defined as Jewish anyone with three Jewish grandparents, or two grandparents if the Jewish faith was followed.

Wehrmacht
The unified armed forces of Germany from 1935 to 1945 were called the Wehrmacht (defence force). This included the Heer (army), Kriegsmarine (navy), and the Luftwaffe (air force). From 2 August 1934, members of the armed forces were required to pledge an oath of unconditional obedience to Hitler personally. In contrast to the previous oath, which required allegiance to the constitution of the country and its lawful establishments, this new oath required members of the military to obey Hitler even if they were being ordered to do something illegal. Hitler decreed that the army would have to tolerate and even offer logistical support to the Einsatzgruppen—the mobile death squads responsible for millions of murders in Eastern Europe—when it was tactically possible to do so. Wehrmacht troops also participated directly in the Holocaust by shooting civilians or committing genocide under the guise of anti-partisan operations. The party line was that the Jews were the instigators of the partisan struggle and therefore needed to be eliminated. On 8 July 1941, Heydrich announced that all Jews in the eastern conquered territories were to be regarded as partisans and gave the order for all male Jews between the ages of 15 and 45 to be shot. By August, this was extended to include the entire Jewish population.

In spite of efforts to prepare the country militarily, the economy could not sustain a lengthy war of attrition. A strategy was developed based on the tactic of Blitzkrieg ("lightning war"), which involved using quick coordinated assaults that avoided enemy strong points. Attacks began with artillery bombardment, followed by bombing and strafing runs. Next the tanks would attack and finally the infantry would move in to secure the captured area. Victories continued through mid-1940, but the failure to defeat Britain was the first major turning point in the war. The decision to attack the Soviet Union and the decisive defeat at Stalingrad led to the retreat of the German armies and the eventual loss of the war. The total number of soldiers who served in the Wehrmacht from 1935 to 1945 was around 18.2 million, of whom 5.3 million died.

The SA and SS
The Sturmabteilung (SA; Storm Detachment), or Brownshirts, founded in 1921, was the first paramilitary wing of the Nazi Party; their initial assignment was to protect Nazi leaders at rallies and assemblies. They also took part in street battles against the forces of rival political parties and violent actions against Jews and others. Under Ernst Röhm's leadership the SA grew by 1934 to over half a million members—4.5 million including reserves—at a time when the regular army was still limited to 100,000 men by the Versailles Treaty.

Röhm hoped to assume command of the army and absorb it into the ranks of the SA. Hindenburg and Defence Minister Werner von Blomberg threatened to impose martial law if the activities of the SA were not curtailed. Therefore, less than a year and a half after seizing power, Hitler ordered the deaths of the SA leadership, including Rohm. After the purge of 1934, the SA was no longer a major force.

Initially a small bodyguard unit under the auspices of the SA, the Schutzstaffel (SS; Protection Squadron) grew to become one of the largest and most powerful groups in Nazi Germany. Led by Reichsführer-SS Heinrich Himmler from 1929, the SS had over a quarter million members by 1938. Himmler initially envisioned the SS as being an elite group of guards, Hitler's last line of defence. The Waffen-SS, the military branch of the SS, evolved into a second army. It was dependent on the regular army for heavy weaponry and equipment, and most units were under tactical control of the High Command of the Armed Forces (OKW). By the end of 1942, the stringent selection and racial requirements that had initially been in place were no longer followed. With recruitment and conscription based only on expansion, by 1943 the Waffen-SS could not longer claim to be an elite fighting force.

SS formations committed many war crimes against civilians and allied servicemen. From 1935 onward, the SS spearheaded the persecution of Jews, who were rounded up into ghettos and concentration camps. With the outbreak of World War II, the SS Einsatzgruppen units followed the army into Poland and the Soviet Union, where from 1941 to 1945 they murdered more than two million people, including 1.3 million Jews. A third of the Einsatzgruppen members were recruited from Waffen-SS personnel. The SS-Totenkopfverbände (death's head units) ran the concentration camps and extermination camps, where millions more were murdered. Up to 60,000 Waffen-SS men served in the camps.

In 1931, Himmler organised an SS intelligence service which became known as the Sicherheitsdienst (SD; Security Service) under his deputy, Heydrich. This organisation was tasked with locating and arresting communists and other political opponents. Himmler established the beginnings of a parallel economy under the auspices of the SS Economy and Administration Head Office. This holding company owned housing corporations, factories, and publishing houses.
