Filippo Tommaso Marinetti published the Manifesto of Futurism on the 5th of February 1909 in the newspaper La gazzetta dell'Emilia. This document marked the official birth of an artistic movement that rejected history and called for a new generation to embrace speed, technology, and violence.
Umberto Boccioni created the bronze sculpture Unique Forms of Continuity in Space in 1913 to translate his ideas about dynamism into three dimensions. The striding figure represents the relationship between an object and its environment through constant motion and now appears on the national side of Italian 20 eurocent coins.
Russian Futurists developed a distinct movement involving literature and visual arts that embraced communist ideals while rejecting Marinetti's nationalism. Unlike Italians who glorified war, many Russian Futurists opposed fascism and obstructed Marinetti when he visited Russia in 1914 before the movement declined after the revolution of 1917.
Antonio Sant'Elia drew plans for La Città Nuova between 1912 and 1914 without ever building his vision because he was killed during the First World War before any designs were realized. His unbuilt city replaced landscape with an efficient fast-paced machine where every aspect of life was centralized into one powerhouse of energy.
Luigi Russolo invented instruments called intonarumori which allowed performers to create and control dynamics and pitch of various noise types inspired by machinery instead of traditional harmony. He and Marinetti gave the first concert of Futurist music complete with these generators in 1914 despite being prevented from performing in many major European cities due to the outbreak of war.
