My friends and I run a discord server rife with historically inspired memes and recently my friend was talking about the ties between futurism as an art movement and Italian fascism. How closely tied together were they? Did one inspire the other? Would also appreciate a good in-depth explanation of futurism as a belief system.
I did answer a very similar question here.
Obviously there's always room for more. Feel freee to ask for clarification - but I believe that the answer essentially touches the points you are interested in.
