Although the Castilian alcalde and the Andalusian qaḍi had slightly different attributes (the qaḍi oversaw an entire province, the alcalde only a municipality; the former was appointed by the ruler of the state but the latter was elected by the municipal council), the adoption of this term reflects how much Muslim society in the Iberian Peninsula influenced the Christian one in the early phases of the Reconquista . As Spanish Christians took over an increasing part of the Peninsula, they adapted the Muslim systems and terminology for their own use . </P>
