I’m looking for books, essays, or any specific writers who focus on these topics and their relationship with each other. I think what I’m looking for is less the aesthetics of political movements themselves, but rather how non-political aesthetics and culture play a role in the beliefs of people those movements are looking to influence.
Take this with a grain of salt as I haven't had time to look any deeper into these books myself, but after a cursory search these might be interesting:
Jacques Rancière - The Politics of Aesthetics
Aesthetic Perspectives on Culture, Politics, and Landscape: Appearances of the Political
From Art to Politics: How Artistic Creations Shape Political Conceptions
Distributions of the Sensible: Rancière, between Aesthetics and Politics
Try the books and TV shows by the UK commentator Jonathon Meades. You can see a lot of his work on YouTube under "Meades-shrine"
Hard to tell what you're looking for exactly, but nonsite.org was a big influence on how I think about these relationships.
