Silver maravedi '1st Granada war' - Alfonso X Burgos

Alfonso X struck these silver maravedis during the Mudéjar revolt of 1264–1268, a coordinated uprising backed by the Nasrid ruler Muhammad I of Granada that destabilized Andalusia and Murcia simultaneously. The revolt forced Alfonso to wage what Castilian chroniclers called the "first Granada war" — a campaign that ultimately cost him significant territorial control and strained royal finances badly enough to matter at the mint.

Burgos production during this window shows tighter silver fineness than some contemporary issues, consistent with a crown still drawing on Castilian northern revenues before southern taxation collapsed.
