Step-by-step explanation:
The text with which Futurism was established as a movement was titled 'The Founding and Manifesto of Futurism'. This groundbreaking text was authored by Filippo Tommaso Marinetti and published in 1909. Marinetti broadcasted the ideals of Futurism, emphasizing speed, movement, and industrial development while attacking traditional cultural values. The Manifesto called for the glorification of war, destruction of museums and libraries, and denounced feminism, striving to shake society up through visual art, architecture, music, and even clothing. This document established an aggressive tone for a movement that was highly politicized and sought to incite change and regeneration in Italy and beyond, setting the stage for a modernist approach to art.
