In December 1921, the poet Manuel Maples Arce (1898 - 1981) papered the walls of Mexico City with his manifesto Actual No. 1, sparking the movement Estridentismo (Stridentism). It is inspired by Mexico's rapid modernization following the Mexican Revolution, the Estridentistas attempted to overturn the status quo in Mexican culture, taking inspiration from contemporary European movements and methods of expression. Mexico's Revolutionary Avant-Gardes provides a nuanced account of the early-twentieth-century moment that came to be known as the Mexican Renaissance, featuring an impressive range of artists and writers. Relying on extensive documentary research and previously unpublished archival materials, author Tatiana Flores expands the conventional history of Estridentismo by including its offshoot movement 30-30! and underscoring Mexico's role in the broader development of modernism worldwide. Focusing on the interrelationship between art and literature, she illuminates the complexities of post-revolutionary Mexican art at a time when it was torn between formal innovation and social relevance.
