Merovech (Latin: Meroveus or Merovius) (d. 453/457) is the semi-legendary founder of the Merovingian dynasty of the Salian Franks (although Chlodio may in fact be the founder), which later became the dominant Frankish tribe. His name is close to Marwig, lit. "famed fight" (cf. mari "famous" + wig "fight") compare modern Dutch mare "news, rumour", vermaard "famous" and vecht "fight". He is said to be one of several barbarian warlords and kings that joined forces with the Roman general Aetius against the Huns under Attila on the Catalaunian fields in Gaul. The first Frankish royal dynasty called themselves Merovingians ("descendants of Meroveus") after him, although no other historical evidence exists that Merovech ever lived.
