You could read the article on the Futurist Manifesto I just linked. Or read the Futurist Manifesto itself.
More broadly, not directly connected to Italian Futurism, you could read An Artist of the Floating World. It’s a pretty good novel.
At least in my experience, many artists are emphatically political, and if you don’t consider their political views, you’re missing much of the context of their work.
