The Salian Franks or Salii were a subgroup of the early Franks who originally had been living north of the limes in the area north of the Rhine. The Merovingian kings responsible for the conquest of Gaul were Salians. From the 3rd century on, the Salian Franks appear in the historical records as warlike Germanic people and pirates, and as Laeti (allies of the Romans). They were the first Germanic tribe from beyond the limes who settled permanently on Roman land. In 358, they came to some form of agreement with the Romans that allowed them to settle in Toxandria (roughly the area of the current Dutch and Belgian provinces of Noord-Brabant, Antwerpen and Vlaams-Brabant).
The Salians fully adopted the Frankish identity and gradually ceased to appear by their original name from the 7th century onward, when they evolved into the Franks par excellence. The Lex Ripuaria originated about 630 around Cologne and has been described as a later development of the Frankish laws known from Lex Salica.
