France began the twentieth century with a bang, confident in itself, in its colonies, in its knowledge, in its virtues. Then came the first world war. Even today, it is not clear who is responsible for the outbreak of this war. What we do know, however, is the extent of the disaster, which makes it difficult to imagine today: in five years 1.45 million deaths for France, 1.9 million injured, that is to say, 30% of the active male population.
This conflict marks a break in the history of our country and in the history of Europe. The technical progress of which Europe was so proud had turned against it. A whole generation was sent to the slaughterhouse in an uncontrollable collective madness. At the end of the war, France was a bit disoriented. Progress continues (electricity was installed everywhere ) but the worm was in the fruit.
