The war was observed with great interest across the world, and the clash between fascism and democracy, the ruling classes and the people, gave rise to mass solidarity with the Republican cause in intellectual circles and among activists and ordinary citizens. The International Brigades and different aid committees for the Republic channelled this widespread social response, which stood outside of official circles of government.
The profession of photojournalism was cemented during this conflict, as was the development of the photo reportage format in an array of illustrated magazines such as Regards and Vu. Moreover, through the experimental development of photo-essays with a naturalist approach, photographers such as Capa conveyed their solidarity and political commitment.
In turn, the international art community’s response was overwhelming and many artists embraced Picasso’s words to the American Friends of Spanish Democracy: “Artists who live and work with spiritual values cannot and should not remain indifferent to a conflict in which the highest values of humanity and civilisation are at stake”. Images of violence and the victims also marked a new way of viewing war, both for reporters like Capa and artists such as Le Corbusier and Lipchitz. The Spanish Civil War would ultimately become a space of experimentation and a testing ground for a committed art that went on to develop across the globe during the Second World War.
