In this life-and-death struggle that decided the fate of mankind, more than 60 countries and regions participated in the war, affecting two billion people (accounting for 80 percent of the world's population at that time), and the flames of war spread to Europe, Asia, Africa, Oceania, the Pacific Ocean, the Indian Ocean, the Atlantic Ocean, and the Arctic Ocean. The area of the operation is 22 million square kilometers, the warring sides have mobilized 110 million troops, more than 55 million soldiers and civilians have died in the war, the total direct military expenditure is about 13 trillion US dollars, accounting for 60 to 70 percent of the total national income of the belligerent countries, and the total value of material losses of the participating countries is 4 trillion US dollars.

1. Similarities:

1. The fundamental reasons are the same: they are all the result of the aggravation of the imbalance in the political and economic development of imperialism.

2. All kinds of intricate contradictions have arisen, and military confrontation groups have emerged.

3. All of them have brought huge losses to the world in terms of manpower and material resources.

4. Both of them dealt a blow to the imperialist forces and promoted the development of the socialist movement and the national liberation movement.

5. After the war, a new international order dominated by the will of the victorious powers was formed, and universal international organizations were established.

Second, the differences.

1. The background is different.

Before the outbreak of the First World War, there was only the capitalist system in the world; The major capitalist countries have formed two major aggressor blocs to constantly create war crises.

Before the outbreak of World War II, in addition to the capitalist system, there was a socialist country.

2. The purpose is different.

During World War I, the main purpose of the warring parties was to divide the colonies and compete for markets and raw material sources. The fascist countries of World War II had to not only defeat each other, but also establish fascist systems all over the world.

3. The nature is different.

The First World War was an unjust war of imperialist plunder; World War II was a just war against fascism waged by liberal capitalist countries and the people of the world for the purpose of defeating fascism and fighting for human security and social progress.

First life.

The world war was not fought thoroughly. Laying the seeds for the Second World War. Britain and France did not completely defeat Germany in the First World War.

Germany capitulated because of the beginning of the November Revolution in the German rear. The Kaiser was overthrown. But that German army was not completely wiped out.

Then there was the Treaty of Versailles indemnity. Germany is brewing revenge. There is another Hitler, a war maniac who is good at fighting.

During World War II, Germany was far stronger than the rest of Europe in terms of strength and tactics under the leadership of Hitler. It has made Britain, France and other countries suffer a lot. The only way to defeat the Nazis was to gather the power of the whole world.

But most of the credit goes to the USSR. That main force of Germany - Army Group **. It was only at the end of the war that it was gradually worn out by the Soviet Union.

It can be said that the USSR saved the entire Western world. But the Soviet Union also consumed too much of its national strength in World War II. After 45 years, it has finally come to the end of time.

Common point 1: The political and economic development of capitalism is unbalanced. 2. It is an unjust war waged by the imperialist powers to compete for world hegemony. 3. It was Germany that provoked the war, but in the end Germany was defeated.

Difference 1: The main battlefield of World War I was in Europe, and the main battlefield of World War II was Europe, Asia, and Africa. 2. After World War II, the international pattern has undergone tremendous changes, Germany has been partitioned and occupied, the strength of Britain and France has been weakened, and the United States and the Soviet Union have become two superpowers to form a cold war. 3. The League of Nations formed after World War I has no practical role, and the United Nations after World War II has played an important role in maintaining world peace.

The Pacific War wiped out a large number of Japanese troops, and the two atomic bombs accelerated the demise of Japanese fascists, which also played a great role in the German War.

1.The root cause of World War II was the uneven development of capitalism.

In the two decades after the First World War, the development of economic and political power in the capitalist countries was in a state of imbalance: Germany and Japan had relatively prominent industrial development and a marked increase in economic strength; Britain, France, the United States, and other countries have successively stagnated.

In 1929 and 1937, the capitalist world experienced two major economic crises. In order to extricate themselves from the economic, political, and social crises, the three fascist-ruled countries of Germany, Italy, and Japan, embarked on the road of militarizing the national economy, and became increasingly fascist politically.

2.The trigger for World War II was the economic crisis.

The economic crisis of the twentieth century was a trigger, like the Ferdinand incident in the Balkans before World War I, but it was global. But it was this fuse that made the war mood of the Germans grow stronger and stronger, and Hitler had an opportunity to take advantage of it.

3.The direct causes of World War II were: Japan's invasion of China; Germany attacked Poland.

On July 7, 1937, Japan provoked the Lugou Bridge Incident and launched a full-scale war of aggression against China. On September 1, 1939, Germany blitzed Poland, and Britain and France declared war on Germany in accordance with the alliance with Poland.
