ABSTRACT
‘Charlemagne was the true organiser of European society. He systematically united its peoples through a political link which remained intact and fulfilled its purpose perfectly from the 8th century to the 15th. ‘Charlemagne knew that the huge population of one entire part of the world and its neighbouring islands, composed of several nations with well-established customs and radically different languages, separated by natural barriers, living in different climates, with different diets, could not live under the same government. He knew that religion was a moral code which should be common to all the European peoples, and that the administrative body, consisting of the ministers of this religion, should also have the character of a general institution. These are the reasons why he decided to give the sovereignty of Rome and its territory to the Pope.
