He united France and much of central Europe. His widespread fame gave rise to many forms of his name. Charles is the French variant of Carolus or Karolus, adopted by the English especially since the 17th-century reigns of kings Charles I and II. Charles and its variant forms have been favoured by the royalty of several countries, including the present Prince of Wales. Charlie and Charly are occasionally used for girls. See also Arlo.
