 Roi fainéant

Roi fainéant (), literally "do-nothing 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 powers of dominion.It is usually applied to those Frankish rulers approximately from the death of Dagobert I in 639 AD (or alternatively, from the accession of Theuderic III in 673) until the deposition of Childeric III in favour of Pepin the Short in 751.
