Iñigo López de Mendoza went to trial with his first cousin, the Princess of Éboli, to claim the Lordship of Puebla de Almenara, founded by their great-grandfather, Cardinal Mendoza, who had established that it could only be inherited through the male line. He subsequently won the lawsuit, becoming Lord of Almenara and in 1587, he became the 1st Marquess of Almenara by the wishes of the king.[4]
In 1623, Philip IV granted another title with the same name, yet making reference to a completely different location near Peñaflor, in the Province of Seville. This subsequent title is sometimes referred to as "Marquess of Dehesa de Almenara" to distinguish it from the older title, despite the official name being the same.
