Career
In 1639 the 9th Duke was married for a second time to Seville noblewoman Juana Fernández de Córdoba, but only after signing documents giving the considerable amount of 20,000 Ducados to Margarita Marañon, on condition she become a nun near his palace in Sanlúcar de Barrameda, later in a Dominican convent. In 1641 the 9th Duke led the Andalusian rebellion against Spanish rule. Though both Portugal and Catalonia had strong cultural identities, an historical record of independence, and popular support, Andalusia did not, and the rebellion failed.
The king of Spain forgave his treason, but the previous prestige of his house was only regained by his successor.
