Kingdom of France
The King of the Franks, Clovis I, sealed the alliance of Frankish Kingdoms with the Catholic Church at his baptism.  That alliance was perpetuated in the Kingdom of France by the crowning of kings at Reims, which made them monarchs by divine right.  The first Capetians were anxious to crown their eldest son in their lifetime because their authority was limited in reality to the Ile de France.  It was not until Philippe Auguste that their official acts called it the Kingdom of France and that they are able to make a real act of authority throughout the kingdom.  Their territory was the feudal fiefs of which king of Western France had been the suzerain since the 843 division of the Carolingian Empire.
