During the Spanish Civil War (1936-1939), artistic demonstrations in Catalonia adopted modern media such as posters and documentary photography.

The vehicle of slogans for awareness and mobilisation, posters stand out for their artistic creativity and techniques during this period.

Some of the most active poster artists were Josep Renau (Hoy más que nunca: Victoria), Martí Bas i Blasi (Feu tancs, tancs, tancs...), Jaume Solà (Unió és força), Lleó Arnau (Assassins!), Carles Fontserè (Llibertat!), Lorenzo Goñi (I tu... què has fet per la victòria?), Pere Català Pic (Aixafem el feixisme), Antoni Clavé (Catalans!... 11 de setembre), Lluís Garcia Falgàs (Informeu-vos dels que lluiten al front), Enrique Ballesteros "Henry" (Voy a luchar por tu porvenir) and Paco Ribera (Diada de la Dona Antifeixista).

Documentary photography offers a testimony of the reality both at the front and in the rearguard during the Civil War. Catalan photojournalists such as Agustí Centelles, Josep Maria Sagarra or Carlos Pérez de Rozas portrayed the daily life of the conflict side-by-side with the foreign professionals such as Robert Capa or Gerda Tardo, creators of legendary images.
