The play was a partial adaptation by the author of his own novel Sonata otoño, which had appeared five years earlier, and is about the adventures of the womanizer Marquis of Bradomin, an aristocrat with political sympathies for the Carlists.
El Marques de Bradomín was staged at the Teatro de la Princesa in Madrid on January 25, 1906. Among the actors featured were Francisco Ortega García and Matilde Moreno, as well as Josefina Blanco who later became the author's wife.
