The history of the financial markets is highly complex but just as fascinating! From the 17th century until today, financial markets have never ceased to grow in importance, bringing with them fantasies, fears, greed and sometimes crises, called "crashes" as if finance was its own world. From the "golden boys" to "Occupy Wall Street", it is a world that separates these two eras, from the love to the hate of finance. However, in the face of tomorrow's challenges, such as the necessary ecological transition, finance finds itself the demiurge of tomorrow! Discover the history of this colorful universe, through the main theses that have marked the financial world, its evolution to the point of being the incarnate evil and the tracks envisaged so that finance is at the service of a more feasible future.
