The Glorious Origins of the Ducal House of Medinaceli

The history of the Ducal House of Medinaceli begins with Infante Don Juan, who was the first Duke of Medinaceli. Upon being appointed in 1368, he established himself at the court of Castile, forging connections with royalty and solidifying the power of his lineage. During the 15th and 16th centuries, the Medinaceli became patrons of the arts and culture, supporting figures such as the famous painter El Greco and the poet Garcilaso de la Vega.

In this context of splendor, the house acquired numerous titles and possessions, including the Marquisate of Tarifa and the County of Gelves. These achievements not only etched their name in the annals of history but also provided them with unparalleled wealth, allowing them to influence the politics and society of their time.

The Rise and Political Intrigues

The Medinaceli were known not only for their wealth but also for their involvement in a complex web of political intrigues. In the 17th century, the Duke of Medinaceli, Don Luis Francisco, was a prominent figure at court, actively participating in the intricate game of loyalties during the War of the Spanish Succession. According to contemporary chroniclers, his ability to maneuver among the different factions made him a significant figure in the tumultuous political landscape of his time.
