Good resources/explanations of pre-capitalist class society? (Especially on the transition between these societies as compared to the transition from capitalism to socialism)

A while back, I was trying to read "understanding the French revolution" by Albert Soboul. However, I never finished it, not because it was necessarily bad but because

A.Was swamped with work and classes

B.Pre-capitalist class relations have always kinda alluded me

I've also read origin of the family, private, property and the state, but I dont remember it talking about that in too much detail (although it was very good [and maybe I just can't remember {I have a really bad memory}]).

I know theres the soviet textbook on political economy from the 50s, but I would prefer something I can obtain physically, since I have difficulty reading on computers.

Thanks in advance
