As soon as the fighting of the Great War was over, the principle of a peace conference was adopted. For six months in 1919, Paris was the capital of the world and the seat of a virtual government under the aegis of the Council of Four: the United States, France, Great Britain and Italy. Based on the work of historian Margaret MacMillan, the film Paris 1919 takes a close look at the historical reality and carefully reconstructs the atmosphere in which the Paris conference took place. Period images and fictional sequences blend together and make clear the narration of a complex event that bears the seeds of the causes that will lead the world to throw itself back into war.
