Acuñaciones monetarias de al-Andalus en la primera mitad del siglo V/XI: fin de un modelo, consolidación de las emisiones regionales

During the first half of the fifth/eleventh century, the caliphal minting practices of the previous century gradually changed, and by the end of this period, a very different monetary system had been established. While in the fourth/tenth century, dinars and dirhams were regularly minted in al-Andalus, by the middle of the next century the number of mints had multiplied and each regional power possessed its own model for the emission of coins. Moreover, the quality of gold and silver coins decreased considerably. The aim of this paper is to perform a comparative analysis of the monetary production developed in the first half of the fifth/eleventh century among the different dynasties of al-Andalus in order to establish the chronological phases that mark the shift from one model of minting to others.
