Illustration of the tacuinum sanitatis on the elaboration of silk (XIV century).
The income of the silk of Granada was a tax of the Crown of Castile on the silk produced and elaborated in Granada. It was established by the Nasrid kingdom and adopted by the Catholic Monarchs after the conquest of the city.
This tax accounted for ten percent of all the production obtained from the breeding of the silkworm in mulberry trees, and worked in the kingdom, and its basis was the price reached in the market. To avoid fraud, trade was monitored from the loom to the alcaicería, and even the cargoes that were transported.
From 1505 it was usual practice to lease this rent to different tenants, and from 1686 the headings of the towns were fixed with a tax of fifteen reales and twelve maravedíes by pound. The collection of this tax was carried out in the alcaicerías of Granada, Malaga and Almeria, and despite the important collection measures, the frauds were numerous. Bibliography
