The Duke of Segorbe is a Spanish noble title created by King Juan II de Aragón in 1476 for Enrique de Aragón, son of Infante Henry, Duke of Villena and Beatriz de Pimentel, from whom the ducal house of Medinaceli descends.
Ignacio Medina y Fernández succeeded in 1969 as XIX Duke of Segorbe before marrying HRH Princess Maria da Glória de Orléans-Braganza in 1985. The Duke and Duchess of Segorbe have two daughters:
As with other Spanish noble titles, the dukedom of Segorbe descended according to cognatic primogeniture, meaning that females could inherit the title if they had no brothers (or if their brothers had no issue). That changed in 2006, since when the eldest child (regardless of gender) can automatically succeed to noble family titles.
