Alfonso X struck these maravedíes to fund the Mudéjar revolt of 1264–1268, a coordinated uprising backed by the Nasrid ruler Muhammad I of Granada and the Marinid sultan of Morocco. The rebellion engulfed Murcia and Andalusia simultaneously, catching Castile badly exposed. Alfonso was forced to recall his son Fernando de la Cerda from the frontier and negotiate emergency financing — this Sevillan silver issue is a direct product of that fiscal pressure.
The .927 fineness held, but the weight crept downward across the emission as the war dragged on. AB#225 is the Sevillan attribution; companion pieces struck at Murcia during the same conflict show subtle die differences in the mint mark placement.
