The Second World War, the second catastrophe in the history of mankind.
World War II, the World War against Fascism, was a war on a global scale that two billion people experienced during World War II. It began on September 1, 1939 and ended on September 2, 1945, and was mainly carried out by the three Axis powers of Germany, Japan and Italy, as well as the servant states of Hungary, Romania, and Bulgaria, on the one hand, and the anti-fascist alliance on the other. The impact of World War II was far-reaching, with profound changes at all levels of politics, economy, military, diplomacy, culture and technology.
The great world economic crisis of 1929 exacerbated the contradictions between Germany, Italy and Japan.
In 1931, Japan launched the 918 Incident, which opened the prelude to World War II.
In 1933, Japan invaded China in full-scale territory, marking the outbreak of World War II in Asia. The Germans attacked Poland on September 1, 1939, followed by the declaration of war by Britain and France, and the outbreak of a full-scale world war. The Soviet Union established the Eastern Front, and Britain and France fought net operations. After the German attack on France, the Anglo-French forces were forced to retreat to Dunkirk.
After the fall of France, de Gaulle continued his struggle against Germany. Germany attacked Britain according to the Sea Lion plan, and the Battle of Britain began. Germany launched a war of aggression against the Soviet Union according to the Barbarossa plan, Japan attacked Pearl Harbor in 1941, and the United States declared war on Japan.
In 1942, the anti-fascist countries strengthened unity by adopting the Declaration of the United Nations, among other things.
In 1943, the Battle of Stalingrad became an important turning point in World War II. On September 8, Italy announced its surrender. On May 8, 1945, Germany announced its surrender. On August 15, Japan announced its surrender, and World War II ended with the victory of the World Anti-Fascist League. Looking at the chronology, the Second World War profoundly changed human history, and its effects were wide-ranging political, economic, military, diplomatic, cultural and technological.
World War II objectively promoted the development of science and technology, and led to the development and progress of aviation technology, atomic energy, heavy artillery and other fields.
