The Visigothic kingdom that stretched over the Iberian Peninsula and Septimania suddenly collapsed in the early eighth century because of the Muslim invasion, which stressed its social and political weaknesses. 1 With the Peninsula converted into Al-Andalus, some political entities organised themselves in the north outside the Muslim domains. In these, the Visigothic legislative code was maintained, as was the case of the territory in the north-east that came under the Carolingian orbit between the end of the eighth and beginning of the ninth centuries. 2 In fact, this code continued to be used in these northern territories throughout the Early and High Middle Ages, 3 not to show any legitimism linked with the Visigothic past, but rather in a practical sense, as a useful and equitable text for settling conflicts and crimes, that also been sanctioned by the Church at the councils of Toledo. 4 Clearly, the strong pressures behind the development of the feudal system in the eleventh century 5 maintained an everyday state based on the legal framework established by the Liber, 6 and were reflected in judicial practice until the twelfth century. 7
