This generic name is usually given to a set of aesthetic, artistic, literary and philosophical trends which, as their name indicates, spearheaded a total revolution which would bring arts and humanities into the contemporary age. The decade between 1910 and 1940 saw the emergence of numerous “isms” such as Surrealism, Ultrism, Fauvism and Cubism, Expressionism and Stridentism…, which not only inundated the literature and the plastic arts of the time, but also other newly-minted arts such as photography and film. The historical scene was also an essential influence: two world wars and the rise of totalitarianisms broke away from the predominant artistic postulates existing in the West up until then. In Spain, its main protagonists led the emergence from the shadow of Modernism and Novecentism, and led to the creative explosion represented by the Generation of 27.
