The move to Madrid coincided with a return to political engagement. Camprodón emerged as a prominent member of the Liberal Union ("Unión Liberal"), a centrist monarchist political grouping which was assuming features of a modern European political party and which, from 1858, was backed by a majority in the Spanish parliament ("Cortes Generales") for a decade. Camprodón became one of the Liberal Union deputies, representing Barcelona and Santa Coloma de Farners, in 1854. He remained a member for five years, and attended party congresses over a period of ten years between 1856 and 1865. He would be remembered as a relatively independently minded party member. Overall, however, his impact on Madrid during the 1850s was more as a fashionably romanticist playwright and poet than as a politician.
