[1] A prominent figure in the court of Alfonso XIII, he held important posts such as gentilhombre Grande de España from 1902, caballerizo mayor from 1906 and was a senator in his own right from 1905 to 1923.

In 1902 he began to serve in the Palace as a gentilhombre Grande de España con ejercicio y servidumbre, just a few days before accompanying the monarch as he swore before the Cortes (on May 17 of that year, when he was proclaimed of legal age in advance).

He would also be an enthusiastic polo player who would contribute to the spread of this sport in the country by organizing, as a groom, the tournaments at the Palacio de la Magdalena and, in particular, a famous annual championship at his estate in Moratalla.

He organized a private trip for the King to the Deauville horse races in August 1922, which was strongly criticized as it took place shortly after the Disaster of Annual, at a time of great political instability.

His funeral enjoyed great resonance in the press and demonstrated the power and influence that the Marquess of Viana had, with Infante Alfonso, the Government in its entirety with Primo de Rivera, as well as the heads of the Palace attending the event.

He married Mencía Collado y del Alcázar, 10th Marchioness of Valle de la Paloma, daughter of the 2nd Marquess of Laguna and the 9th Countess of Montalvo, in 1896 in Madrid.
