Why did World War II happen?

World War II was the second war on a global scale fought by the three fascist Axis powers of the Third Reich, the Empire of Japan, and the Kingdom of Italy and their client states, with the Anti-Fascist League and the anti-fascist forces of the world on the other. The scope of the war ranged from Europe to Asia, from the Atlantic to the Pacific, and there were 61 countries and regions

More than 2 billion people were involved in the war, and the area of operations was 22 million square kilometers. According to incomplete statistics, more than 90 million military and civilian people were killed in the war, and more than 5 trillion US dollars were wasted, making it the largest world war in human history and the most destructive war in human history.

So how exactly did this war break out? In fact, in a sense, the Second World War can be seen as a continuation of the First World War.

The first is the economic factor, in the 30s of the 20th century, the worst economic depression in history occurred in Western countries. The most typical example is a ** on Wall Street in the United States, where a rich man posted a note on his luxury car. At that time, many of the American middle class went bankrupt, the wealthy class was also affected, and the bottom fell into a huge unemployment crisis.

In order to solve the crisis, Roosevelt** in the United States began large-scale civil engineering construction, and the Tennessee Dam is a masterpiece of this period. Roosevelt's tactics helped the United States turn the crisis around, but Germany and Japan were not so lucky.

At this time, Germany and Japan were in danger of erupting volcanoes due to the Great Depression. Japan is a small country with few resources, in order to reverse the crisis, in 1931 sent troops to occupy China's resource-rich northeast, using China's resources to stabilize the situation in Japan, while ensuring a huge amount of military energy.

The twenty years between the two world wars can be divided into two distinct phases, with 1929 as the boundary, the first decade was the period when Europe was gradually recovering from the wounds of the First World War, the belligerent Germanic Germany joined the League of Nations, many European countries were reconciled, the issue of reparations was settled, and peace seemed to come forever. However, after 1929, the Great Depression, which was pioneered by the United States and rapidly spread around the world, changed the world situation, especially in Europe, where suspicion and fear were everywhere. In order to protect themselves, countries have raised tariffs, and the so-called economic self-sufficiency has taken root in the hearts of the people.

Because the capitalist world has produced economic crises, which have intensified the contradictions between domestic and foreign countries. In order to expand their territory, the fascist countries constantly launched wars and aggression against foreign countries.

Because of Hitler's rise to power, the German system was changed. In order to promote national sentiments, Hitler unleashed World War 2.

It is because of the uneven distribution of territory among the imperialist countries. They all wanted a little more territory of their own, and so there was World War 2.

The Second World War broke out in September 1939, and the main contradiction was the uneven economic and political development of capitalism, which was caused by the economic crisis.

Background: After the First World War, the economic and political development of capitalist countries was unbalanced, with the industrial development of Germany and Japan being more prominent, and the stagnation of Britain, France, and the United States. In 1929 and 1937, there were two serious economic crises in the capitalist world.

In order to extricate themselves from the economic, political, and social crisis, the countries ruled by the German, Italian, and Japanese fascists embarked on the road of militarizing the national economy, and became increasingly fascist politically, and gradually formed two major political and military blocs of the United States, Britain, and France, and Germany, Italy, and Japan.

World War II was fought on a worldwide scale with the three fascist Axis powers of Germany, Japan, and the Kingdom of Italy, and the anti-fascist alliance and the anti-fascist forces of the world as the other side.
