The lands consisting of the Señorio del Castillo de Carpio were conquered by King Ferdinand III of Castile in 1240 as a part of the larger Reconquista.

The tower was completed in 1325 which is also the date associated with the founding of the Señorio del Castillo de Carpio.

In 1559, the title was upgraded to the Marquesado del Carpio in 1559 by King Philip II of Spain to the relevant holder, Diego Lopez de Haro y Sotomayor on 20 January 1559 in recognition of his services to the crown,[2] It is unclear whether the first Marques of Caprio was in fact Diego López de Haro y Sotomayor.

[4] What does appear clear is that Luis Méndez was indeed the 9th Señor del Carpio inheriting the title from his parents and that his son Diego López was also the Marques.

Luis Méndez inherited the Señorio del Carpio from his mother Beatriz Portocarrero Cárdenas in 1528 according to Margarita Cabrera Sánchez.
