Kingdom of Aragon
The first counts of the Marca Hispanica were Franks, but in time they were replaced by local elites, Vasconas and Hispano-Visigoths. The kings of Pamplona and later of Aragon promoted the immigration of Franks and Occitanians to their kingdoms, as well as Mozarabs. With the invasion of the Almohad fundamentalists, Jewish communities from al-Andalus also migrated to the Christian kingdoms. After the conquest of the Ebro valley, a considerable number of Muslims became subjects of the king of Aragon. These Muslims, called Mudejars, formed an important part of the artisan and agricultural class of the kingdom, as reflected in the widespread Aragonese Mudejar architecture.
