During World War II, France, as an anti-fascist country, also participated in World War II. At that time, France, as the fifth largest power in the world, should be the mainstay of anti-fascist countries. But as a result, France only contacted Germany once, and was overthrown by Germany, and the country was occupied by Germany. Although France did not make any contribution in World War II, it became the five permanent members of the United Nations, because its own strength is still very strong.

World War II was a war that swept the world, and many countries in the world joined the war actively or passively. The war destroyed the three fascist regimes of Germany, Italy and Japan, but at that time Britain, the Soviet Union and other powerful countries were also hit hard. The only thing that didn't get hit hard in the war, besides the powerful United States, should be France. Because France was occupied by Germany after the French campaign, the French chose to cooperate with Germany, so the French mainland did not suffer much damage.

The Vichy government of France not only retained the land in the south of France and the vast overseas colonies, but also had the right to manage the German-occupied areas in the north. The Germans chose to let the French take charge of the northern region, let France continue its normal production, and then continue to create wealth and taxes to provide a source of funds for their frontline operations.

Therefore, in World War II, the industrial and economic development of France was not greatly affected by the war, and France continued to develop. During World War II, other countries fought bloody battles for their own territory, while the French enjoyed economic development. So at the end of World War II, all countries were basically facing the problem of economic recession, but the strength of the French people was greatly improved.
