Stridentism (1921-1929) was one of the first avant-garde literary and artistic movements after the Mexican Revolution. It established the movement that constructed an imaginary of the modern city through two cultural channels: literature and graphic art/painting. Little by little, new post-revolutionary values ​​came to light: education (Vasconcelos), technology and progress that could only be found in the city. Mexico was just emerging from the authoritarian obscurantism of Porfirio Díaz and modernist and romantic poetry. Stridentism was born, first of all, from a new poetic and intellectual questioning within an area in the process of formation: the city. Until then, poetry was essentially “rural” and bucolic, where natural elements were the only ones that could generate or inspire it. The Estridentista movement manifested itself in an essentially urban context, through manifestos (posters posted on walls), meetings in a café (El Café de Nadie), magazines (Ser, Irradiador and Horizonte) and book publications with the support of the governor of the State of Veracruz, Heriberto Jara in Xalapa. The contribution of Estridentismo is fundamental to Mexican cultural life, through its poetry and literature and the graphic proposals of its artists.
