Roi fainéant, literally “do-nothing king” and so presumptively “lazy king“, is a French term primarily used to refer to the later kings of the Merovingian dynasty, after they seemed to have lost their initial energy. They were considered and portrayed “useless” by Carolingian kings and even early modern historians, though current historical opinion is more nuanced.
