Does anyone here have Leftist theory specifically originating from Shiism? Particularly authors and their works.

The only author I know of is Ali Shariati, and I have trouble finding his work. I linked his essay "Red Shiism vs. Black Shiism" as an example of what I potentially am looking for. Sorry if this is a bit if an odd request, this us my first Lemny post. Anything linked would be helpful.
