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