What is "stridentism"

Stridentism (Spanish: Estridentismo) was an artistic and multidisciplinary avant-garde movement, founded in Mexico City by Manuel Maples Arce at the end of 1921 but formally developed in Xalapa where all the founders moved after the University of Veracruz granted its support for the movement. Stridentism shares some characteristics with Cubism, Dadaism, Futurism and Ultraism, but it developed a specific social dimension, taken from Mexican Revolution, and a concern for action and its own present. Stridentists were part of the political avant-garde, faced to the "elitist" modernism of Los Contemporáneos.
