Sudetenland in the context of "First Czechoslovak Republic"

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 Anschluss (German: [ˈʔanʃlʊs] , or Anschluß, lit. 'joining' or 'connection'), also known as the Anschluß Österreichs (pronunciation, English: Annexation of Austria), was the annexation of the Federal State of Austria into Nazi Germany on 12 March 1938.

The idea of an Anschluss (a united Austria and Germany that would form a "Greater Germany") arose after the 1871 unification of Germany excluded Austria and the German Austrians from the Prussian-dominated German Empire. It gained support after the Austro-Hungarian Empire fell in 1918. The new Republic of German-Austria attempted to form a union with Germany, but the 1919 Treaty of Saint Germain and Treaty of Versailles forbade both the union and the continued use of the name "German-Austria" (Deutschösterreich); they also stripped Austria of some of its territories, such as the Sudetenland. This left Austria without most of the territories it had ruled for centuries and amid economic crisis.

The Munich Agreement was reached in Munich on 30 September 1938, by Nazi Germany, the United Kingdom, France, and Italy. The agreement provided for the German annexation of part of Czechoslovakia called the Sudetenland, where three million people, mainly ethnic Germans, lived. The pact is known in some areas as the Munich Betrayal (Czech: Mnichovská zrada; Slovak: Mníchovská zrada), because of a previous 1924 alliance agreement and a 1925 military pact between France and the Czechoslovak Republic.

Germany had started a low-intensity undeclared war on Czechoslovakia on 17 September 1938. In reaction, Britain and France on 20 September formally requested Czechoslovakia cede the Sudetenland territory to Germany. This was followed by Polish and Hungarian territorial demands brought on 21 and 22 September, respectively. Meanwhile, German forces conquered parts of the Cheb District and Jeseník District, where battles included use of German artillery, Czechoslovak tanks, and armored vehicles. Lightly armed German infantry briefly overran other border counties before being repelled. Poland grouped its army units near its common border with Czechoslovakia and conducted an unsuccessful probing offensive on 23 September. Hungary moved its troops towards the border with Czechoslovakia, without attacking. The Soviet Union announced its willingness to come to Czechoslovakia's assistance, provided the Red Army would be able to cross Polish and Romanian territory; both countries refused.

Bohemia (/boʊˈhiːmiə/ boh-HEE-mee-ə; Czech: Čechy [ˈtʃɛxɪ] ; German: Böhmen [ˈbøːmən] ) is the westernmost and largest historical region of the Czech Republic. Bohemia can also refer to a wider area consisting of the historical Lands of the Bohemian Crown ruled by the Bohemian kings, including Moravia and Czech Silesia, in which case the smaller region is referred to as Bohemia proper as a means of distinction.

Bohemia became a part of Great Moravia, and then an independent principality, which became a kingdom in the Holy Roman Empire. This subsequently became a part of the Habsburg monarchy and the Austrian Empire. After World War I and the establishment of an independent Czechoslovak state, the whole of Bohemia became a part of Czechoslovakia, defying claims of the German-speaking inhabitants that regions with German-speaking majority should be included in the Republic of German-Austria. Between 1938 and 1945, these border regions were annexed to Nazi Germany as the Sudetenland.

Bavarian (Boarisch or Bairisch; German: Bayrisch [ˈbaɪʁɪʃ] ), alternately Austro-Bavarian, is a group of Upper German varieties spoken in the south-east of the German language area, including the German state of Bavaria, most of Austria, and South Tyrol in Italy. Prior to 1945, Bavarian was also prevalent in parts of the southern Sudetenland and western Hungary. Bavarian is spoken by approximately 12 million people in an area of around 125,000 square kilometres (48,000 sq mi), making it the largest of all German dialects. In 2008, 45 percent of Bavarians claimed to use only dialect in everyday communication.

Czechoslovakia (/ˌtʃɛkoʊsloʊˈvæki.ə, ˈtʃɛkə-, -slə-, -ˈvɑː-/ CHEK-oh-sloh-VAK-ee-ə, CHEK-ə-, -⁠slə-, -⁠VAH-; Czech and Slovak: Československo, Česko-Slovensko) was a landlocked country in Central Europe created in 1918 when it declared its independence from Austria-Hungary. In 1938, after the Munich Agreement, the Sudetenland became part of Nazi Germany. Between 1939 and 1945, the state ceased to exist, as Slovakia proclaimed its independence and Carpathian Ruthenia became part of Hungary, while the German Protectorate of Bohemia and Moravia was proclaimed in the remainder of the Czech Lands. In 1939, after the outbreak of World War II, former Czechoslovak president Edvard Beneš formed a government-in-exile and sought recognition from the Allies.

After World War II, Czechoslovakia was re-established under its pre-1938 borders, with the exception of Carpathian Ruthenia, which became part of the Ukrainian SSR (a republic of the Soviet Union). The Communist Party seized power in a coup in 1948. From 1948 to 1989, Czechoslovakia was part of the Eastern Bloc with a planned economy. Its economic status was formalized in membership of Comecon from 1949 and its defense status in the Warsaw Pact of 1955. A period of political liberalization in 1968, the Prague Spring, ended when the Soviet Union, assisted by other Warsaw Pact countries, invaded Czechoslovakia. In 1989, as Marxist–Leninist governments and communism were ending all over Central and Eastern Europe, Czechoslovaks peacefully deposed their communist government during the Velvet Revolution, which began on 17 November 1989 and ended 11 days later on 28 November when all of the top Communist leaders and Communist party itself resigned. On 31 December 1992, Czechoslovakia split peacefully into the two sovereign states of the Czech Republic and Slovakia.

The European theatre of World War II was one of the two main theatres of combat during World War II, taking place from September 1939 to May 1945. The Allied powers (including the United Kingdom, the United States, the Soviet Union and France) fought the Axis powers (including Nazi Germany and the Kingdom of Italy) on both sides of the continent in the Western and Eastern fronts. There was also conflict in the Scandinavian, Mediterranean and Balkan regions. It was an intense conflict that led to at least 39 million deaths and a dramatic change in the balance of power in the continent.

During the 1930s, Adolf Hitler, the leader of Nazi Germany, expanded German territory by annexing all of Austria and the Sudetenland region of Czechoslovakia in 1938. This was motivated in part by Germany's racial policy that believed the country needed to expand for the pseudoscientific "Aryan race" to survive. They were aided by Italy, another fascist state which was led by Benito Mussolini. World War II started with Germany's invasion of Poland on 1 September 1939, and the Soviet Union, led by Joseph Stalin, joined the invasion later that month. The two nations then partitioned Poland between them.

Kristallnacht (German pronunciation: [kʁɪsˈtalnaχt] lit. 'crystal night') or the Night of Broken Glass, also called the November pogrom(s) (German: Novemberpogrome, pronounced [noˈvɛm.bɐ.poˌɡʁoːmə] ), was a pogrom against Jews carried out by the Nazi Party's Sturmabteilung (SA) and Schutzstaffel (SS) paramilitary forces along with some participation from the Hitler Youth and German civilians throughout Nazi Germany on 9–10 November 1938. The German authorities looked on without intervening. The euphemistic name Kristallnacht comes from the shards of broken glass that littered the streets after the windows of Jewish-owned stores, buildings, and synagogues were smashed. The pretext for the attacks was the assassination, on 9 November 1938, of the German diplomat Ernst vom Rath by Herschel Grynszpan, a 17-year-old German-born Polish Jew living in Paris.

Jewish homes, hospitals and schools were ransacked as attackers demolished buildings with sledgehammers. Rioters destroyed over 1,400 synagogues and prayer rooms throughout Germany, Austria, and the Sudetenland. Over 7,000 Jewish businesses were damaged or destroyed, and 30,000 Jewish men were arrested and incarcerated in concentration camps. British historian Martin Gilbert wrote that no event in the history of German Jews between 1933 and 1945 was so widely reported as it was happening, and the accounts from foreign journalists working in Germany drew worldwide attention. The Times of London observed on 11 November 1938: "No foreign propagandist bent upon blackening Germany before the world could outdo the tale of burnings and beatings, of blackguardly assaults on defenceless and innocent people, which disgraced that country yesterday."
