[en] Abstract from English Wikipedia: \"José Osorio y Silva, 9th Duke of Sesto, 16th Duke of Alburquerque, 16th Marquess of Alcañices (4 April 1825, Madrid - 30 December 1909, Madrid), was a Spanish nobleman, politician and army officer. He was also known by his title Duke of Sesto, inherited from his father, and by nicknames Pepe Osorio or Pepe Alcañices. He was head and representative of the houses of Alcañices, Alburquerque and los Balbases, causing a personal union of sixteen noble titles and four grandee titles. He is also considered one of the most notable mayors of Madrid, serving from 1857 to 1864. He had inherited strong monarchist convictions as a result of his education and family tradition. During the Glorious Revolution he convinced Isabel II that the only way to re-establish the monarchy was for her to abdicate - he was the first to sign the abdication document and became so involved in the process that the queen told her son \"Alfonso, shake hands with Pepe, who has managed to become king\". During the royal family's exile he paid their expenses and put his residence in Deauville at their disposal. He then paved the way for the restoration of the monarchy and the accession of Isabel's son Alfonso XII, on which he spent much of his family fortune. Alfonso XII came to look on him as a second father and throughout Alfonso's life José was his best friend and main advisor. He also acted as mentor to prince Alfonso (the future Alfonso XIII) and José's wife, the Russian princess Sofí­a Troubetzkoya, built up support for the restoration socially among the Spanish nobility while José's friend Antonio Cánovas del Castillo consolidated support politically. On Alfonso XII's death in 1885, José was disgraced before his widow Maria Christina of Austria and left the Spanish court. He spent his last years back in politics as well as on business and leisure travel across Europe with his wife. He died aged 84 in his palace of Paseo de Recoletos on the thirty-fifth anniversary of the start of the restoration of the monarchy. He left no children and named his nephew Miguel Osorio y Martos as his heir.\"
