Love Blackshirts & Reds for more recent history, but also would like to throw in The Assassination of Julius Caesar if you are interested in the politics of Rome at all. It's way more similar to Amerikan "democracy" than one might believe (not just "descended from").

There were multiple almost-uprisings that were quashed by the ruling class, and this work goes into grueling detail regarding them. I do not view Rome the same as I did prior to reading it, or Amerika for that matter.

Blackshirts and the Reds (obvi), To Kill A Nation (recent history of the destruction of Yugoslavia, a lot of parallels to Ukraine), Inventing Realities (I’ve heard it’s like Manufacturing Consent, but better), and Against Empire. There are probably other good ones that I don’t know much about. I wasn’t much interested by The Assassination of Julius Ceasar, but if you’re into Roman history it’s probably good.

(Not the original reply but) Depends on the interest, but I started with Blackshirts and the Reds (deconstructing the red fascist myths and northwestern lies about the Soviet Union) and it was an amazing read. They're usually really short and straightforward to read, so any of them will do as the first one.

Second Blackshirts & Reds, it's a very easy read and highly informative.

I recall reading that he considered himself a Marxist, and he does appear to support revolutionary approach to social change in his books. While Ministry for the Future isn't perfect, it did some economic analysis showing that capitalism is fundamentally at odds with having a livable future. The whole thesis of the book is that capitalism needs to be abolished, and the book also doesn't shy away from saying that violence will be necessary to do so. It also talks positively about USSR saying that it had the right idea all along.
