This paper, where we are going to present the results of our doctoral thesis project, focuses its attention on the study of the lordships, properties, rents and patrimony linked to the Duchy of Alcalá and the County of Santa María, governed by the Enríquez de Ribera and Cerda lineage, located in the old kingdom of Seville, between the current provinces of Seville and Cadiz, which will form a set of territorially unitary lordships and almost all located on the Atlantic coast of Andalusia. Both houses will unite to form the Ducal House of Medinaceli in the kingdom of Seville in the 17th century.  We analyze the origin, evolution and content of the rents of the duchy of Alcalá, and also of the rents of the county of El Puerto de Santa María between the 14th and 16th centuries, attending to the different localities that formed these lordly states; we study their typology, whether they were on the agricultural production, the handicraft, the real estate properties, the monopolies, the almonas, the ports, etc. And above all their royal transfer in customs and the traffic of goods (alcabalas, portazgos, almojarifazgos, etc.). We also focus our study on the analysis of the fiscal agents and the power relations between lords, vassals, and the Crown that establish the basis of the fiscal system in the Duchy of Alcalá and the County of El Puerto de Santa María. In the same way, we focus our attention on the study of the centralization of the revenue management at the beginning of the 16th century through the consolidation of systems of collection and management of the seigniorial income through the offices of the seigniorial mayordomías, seigniorial agents that became the apex of a gear that would establish a network of relationships both horizontally and vertically with tenants, urban elites, servants and clients of the lord.
