What time periods/places are you interested in? I am able to and would be happy to give you a detailed list of primary and secondary sources for a good chunk of concepts.

That’s the big thing - historians tend to focus. Even the university “western history from 1500” or whatever are going to vary a lot by what the professor is interested in and focused on. Behind just focusing on like a whole country or time period, they get super specific and do shit like figure out that whole undocumented kingdoms existed based on numismatic work (coins) or look at things like architectural influences that the crusaders brought back and can be seen in their classes (I had a prof who had a whole feminist interpretation of medieval castle architecture)

Your comment alludes to the history of religion, which is definitely a complicated topic and has its own complexities in historiography (the study of history and techniques). Religion has interactions with so many other spheres, and so you have also often dive deeply into the culture and history of the specific people who practiced it to understand the why - which is hard, because religious interpretations that are common now tend to get read backwards into the text.

I’d be happy to give you a list of sources for any religion as well.
