Francs rhénans
The later Merovingian kings responsible for the conquest of Gaul are thought to have had Salian ancestry, because they applied so-called Salian law ("Lex Salica") in their Roman-populated territories between the Loire and Silva Carbonaria, although they also clearly had connections with the Rhineland or Ripuarian Franks. The "Lex Ripuaria" originated about 630 and has been described as a later development of the Frankish laws known from "Lex Salica". On the other hand, following the interpretation of Springer the "Lex Salica" may simply have meant something like "Common Law".
