Final answer:
The Futurists drew inspiration from Cubism to celebrate and glorify themes of speed, technology, and modernization, guided by Filippo Tommaso Marinetti's 'Futurist manifesto'.
Step-by-step explanation:
The Futurists were inspired by Cubism and glorified themes such as speed, technology, youth, and violence, as well as modern innovations like the car, the airplane, and the industrial city. After encountering Cubism in Paris in 1911, they integrated its techniques to express the dynamism and movement they so admired. Filippo Tommaso Marinetti, the de facto leader of the Futurists, was pivotal in setting a fiery tone for the movement with his publication of the 'Futurist manifesto' in 1909, sharply critiquing the cultural tradition and advocating for the representation of modernity in art. The manifesto was followed by various others that encompassed a spectrum of arts, all uniting under the futuristic ideology that heralded the Machine Age as the precursor to a new world order.
