Is there any good reading material that explains the 1956 Hungarian uprising and the 1968 Prague Spring from an ML perspective?

A book I can recommend on the Hungarian uprising is The Truth About Hungary by Herbert Aptheker.

It's been a while since I read it but to my recollection it makes a pretty undeniable argument that it was a fascist uprising, taking place as it did just 11 years after Hungary - an Axis member - was defeated in WW2.

TheFinnishBolshevik has done an excellent and well-sourced series on the Hungarian uprising : https://www.youtube.com/playlist?list=PLbnLysSug0vS6GirUcyM-53gm0T6f0Kc0

You can find a bunch of good books to read about it in his video descriptions.
