World War I led to the collapse of four great powers: the Empire of Russia, the Empire of Austria and Hungary, Germany, and the Ottoman Empire, of which Syria was part of its legacy. The collapse of the Ottoman Empire encouraged the victorious colonial powers of England and France to share its legacy by creating a new colonial concept known as the "Mandate", conceived and put into practice by the allied and victorious powers of that time, namely France, England, the United States, and Italy.[1] The main idea is that the former geographic possessions of the collapsed states that disappeared at the end of the First World War (Germany and the Ottoman Empire) would be placed under the supervision of the League of Nations (the former global organization of the current UN), since Germany had lost its colonies in Africa, the Ottoman Empire should also cede all its Arab states.[1]
