I've heard it on this sub before that the concept of 'race' as we know it today is mostly an 18th and 19th century construct. To what extent is that true? What did race relations look like in the ancient and medieval world? To what extent are racist ideologies based in classism?
Have you read Kendi's recent book on race in America, Stamped from the beginning? It would be a good (accessible, informative, and well-regarded--it just won two national awards) starting point for your research: https://www.amazon.com/Stamped-Beginning-Definitive-History-National/dp/1568584636
Hello there.
