Pepin reestablished the old Gothic county with its seat at Ruscino. The new count—a Goth—built a castle at their capital: the "castrum" or "castellum Rossilio", by which Ruscino came to be known as Castell-Rosselló. Beginning in 780, Charlemagne started granting "aprisiones" of unpopulated land in Roussillon and around Narbonne to incoming "spani" (or "hispani", that is, Christian Spaniards of Gothic, Roman, and Basque origin). These "spani" migrants, along with the native Gothic aristocracy, took part in the reconquest of the southern slopes of the Pyrenees and the Tarraconensian littoral which formed the new Marca Hispanica.
