The origins of the House of Osuna date back to the 15th century, but it was in the 17th century that its influence reached its peak. During this time, the title of Duke of Osuna was created in 1520 by King Charles I, granting the family an unprecedented status in Spanish society. This title not only entailed territorial recognition but also provided access to the highest echelons of power at court. In fact, during this century, the House of Osuna became a model for other noble houses, particularly regarding the management of their estates and relations with the Crown.
The most prominent figure of the house during this period was the third duke of Osuna, Don Pedro Téllez-Girón y Pacheco. Born in 1586, Don Pedro was a nobleman who not only administered his lands wisely but also actively participated in the politics of the time. He is known for being a patron of the arts and a promoter of culture, aspects that contributed to the projection of the House of Osuna as a cultural reference in Spain. Under his patronage, the splendid family residence in Osuna became a gathering center for artists, writers, and thinkers of the era. Furthermore, his interest in art and literature not only beautified his home but also left an indelible mark on the cultural history of Andalusia.
