Alfonso X ordered this issue specifically to fund military operations during the Mudéjar revolt of 1264–1268, when the Muslim populations of Murcia and Jerez — resettled under Castilian rule after Fernando III's conquests — rose simultaneously, backed by the Marinid sultan of Granada, Muhammad I. The Murcian mint, only recently brought under Castilian control, was activated for this emission. Alfonso ultimately required Aragonese military intervention to suppress the revolt, a humiliation that colored his subsequent monetary and political reforms.
