Charlemagne (2 April 742 ??28 January 814 CE), also known as Charles the Great (Latin: Carolus or Karolus Magnus, French: Charles Le Grand or Charlemagne, German: Karl der Grosse, Italian: Carlo Magno or Carlomagno) or Charles I, was King of the Franks who united most of Western Europe during the Middle Ages and laid the foundations for modern France and Germany. He took the Frankish throne from 768 and became King of Italy from 774. From 800 he became the first Holy Roman Emperor - the first recognized Roman emperor in Western Europe since the collapse of the Western Roman Empire three centuries earlier. The expanded Frankish state he founded is called the Carolingian Empire.

Maugris or Maugis was one of the heroes of the chansons de geste and romances of chivalry and the 'Matter of France' that tell of the legendary court of King Charlemagne. Maugis was cousin to Renaud de Montauban and his brothers, son of Beuves of Aygremont and brother to Vivien de Monbranc. He was brought up by Oriande the fairy, and became a great enchanter. He won the magical horse Bayard and the sword Froberge which he later gave to Renaud.
