(World War II) referred to as World War II or World War II. From 1939 to 1945, Germany, Italy, Japan and their subordinate countries launched the largest Second World War in human history, with 61 countries and regions (twice the First World War!) , A population of more than 2 billion was involved in the war, and more than 102.21 million soldiers and civilians died. In the end, the failure of the three fascist countries of Germany, Italy, and Japan ended. [Edit this paragraph] The origin of war The reason for the rise of Nazi Germany In the First World War, the Allied Powers defeated the Allied Powers. In November 1918, after the war, the German Emperor Wilhelm II abdicated, and on June 28, 1919, Germany signed the Treaty of Versailles. On July 31, 1919, the National Assembly passed the Weimar Constitution in Weimar, a small city in southern Germany, proclaiming the establishment of the Weimar Republic. As France was hit hard by Prussia in the Franco-Prussian War in 1870, after World War I, France hoped to retaliate economically against Germany and ultimately weaken this powerful neighbor. 'The Treaty of Versailles' imposed extremely stringent economic and military sanctions on Germany. The German Empire lost 13% of its land and 12% of its population. Germany was disarmed. The German Wehrmacht was controlled below 100,000, and it was not allowed to have an air force. . Although Germany was finally defeated in World War I, the vitality of the German Empire did not suffer too much damage, the industrial system was still intact, and Germany itself was not affected by the war. The Treaty of Versailles only considered victorious nations. The distribution of benefits, the unprecedented harshness and predatory nature of the treaty, plus the general denial of military defeat in Germany. The German citizens have a strong sense of resistance and resentment towards the Treaty of Versailles, and aroused strong national revenge sentiments among ordinary Germans. After a short period of stability, the Weimar Republic, which cannot be ruled out from the outside and cannot solve the internal troubles, was hit hard by the global financial crisis in 1929. This fragile republic is facing serious economic problems and is on the verge of bankruptcy. The German people’s life is very difficult, which provides a good opportunity for the rise of extreme right-wing forces in Germany. The German National Socialist Workers’ Party (Nazi) led by Adolf Hitler is one of them. He claimed that the roots of Germany’s plight came from the severe provisions imposed on Germany after the war, the cowardly Weimar Republic and Jews alleged to have the lifeblood of the country’s economy. His theory was supported by more and more Germans. By 1933, the Nazi Party had grown from a trivial small party to the largest party in Congress. On January 30, 1933, Marshal Hindenburg officially appointed Hitler as Prime Minister of the Republic. At the same time, Hitler's government performed its official duties by exercising the special powers granted to the president by the Constitution in emergency situations, which allowed Hitler to overstep the Federal Parliament to exercise actual dictatorship. At this time, the Weimar Republic has reached the end of its political life, replaced by the German Third Reich. In order to get rid of the shackles of Britain and France and other countries on the German Empire, Hitler announced in October 1933 that he would withdraw from the League of Nations controlled by Britain and France because of restrictions on his arms expansion and war preparation plans. After Hindenburg's death on August 2, 1934, Hitler succeeded as president in accordance with the constitution and became the only leader of the Third Reich with real power. He was called the 'head of state' in German. Before the war, Hitler was not a politician who only clamored for empty talk. After he took office, he quickly rebuilt the order in Germany. In addition, he had a vision to allow the working class at the bottom of society to enjoy benefits that they did not have in the past. Hitler's approval rating increased significantly. The political situation in the German Empire has stabilized, and the Nazis have begun to focus on diplomacy and have taken many risky actions. On March 16, 1935, Hitler announced that the German army would reorganize its armaments and implement a conscription system, thus breaking through the limitations of the Treaty of Versailles. The Sudetenland of Austria and Czechoslovakia were merged into the Third Reich. The rest of the Czech Republic was soon occupied by Germany. Part of Slovakia was independent under the protection of Germany; the rest of Czechoslovakia was divided. In 1936, Germany and Japan agreed on the 'Anti-Communist International Agreement.' The 'Berlin-Tokyo axis' was formed. A year later, Italy joined the agreement, and the axis of Germany, Italy, and Japan was formally formed. In March of the same year, Hitler violated the 'Treaty of Versailles' and ordered 30,000 German troops to enter the Rhineland. As a result, Britain and France did not react. This risky throw made Hitler's appetite growing. He ordered the German army to quickly build a large number of sophisticated military weapons in preparation for external expansion. On the night of August 31, 1939, the German army was wearing a Polish uniform and approached a small town in Glewitz on the Polish border. After successfully occupying the town, the German army deliberately destroyed the town’s radio station and fired into the air. Afterwards, the German people who were listening to the radio program heard a voice with a Polish accent proclaiming: 'Polish people! The war between Poland and Germany is about to start, unite, defeat the German devils, and defeat all war against us. Germans!'
