In this article, we will explore the fascinating history of this nobility, its splendor, and its eventual decline, all backed by historical documents and chronicles of the time.

The Origins of the Ducal House of Medinaceli

The Ducal House of Medinaceli was founded by the nobleman Don Juan de la Cerda in 1368, during the reign of Peter I of Castile. This first duke, whose lineage became intertwined with the history of Spain, was also a man of war and a shrewd politician. His nobility was confirmed after the Battle of Nájera, where his loyalty to the king earned him this title.

The Cerda family quickly prospered, and their power solidified as one of the closest lineages to the monarchy. Medinaceli, a town located in the province of Cuenca, became the center of their noble empire. The dukes not only administered lands; they were key figures in the political plots that defined the fate of the Iberian Peninsula, engaging in marriage alliances and power agreements that would shape history.
