I like a lot of things though I've only really gone "in depth" with this 12th century fixation of mine...I also really like classical/biblical eras, like the first century Jesus era stuff because I was really into that for a while, with the Greco-Roman influence on the early church and second temple Judaism. Since it's something that is incredibly important both to traditions and incredibly politicized and thus has affected a lot of culture to this day while also being on its own, a very specific snapshot of a time and place and cultural mix of language and ideals that often is mentioned a lot by both Christian pundits and people trying to find progressive spins on ancient texts. It's still something important to me, but studying religious stuff sometimes makes me a little sad and also annoying pedantic personally fjdj so I've distanced a bit over the years. There are some sexy scenarios I'd like to explore in that context but mostly they're less based on history and more parodic porn stuff inspired by the fetishization of that era by Christian martyr and saint narratives (you can only have so many stories about virginal pure concerts being bound and tortured and whipped or whatever out of devotion by eeeevil sexy Romans lying on couches with slaves fanning them with palms without it becoming kinda....)

I think a lot of early American and Colonial history is really fascinating to me (if also very depressing), I was really into stuff about the Jamestown and New England settlements for a while, (very APUSH, I know, but also I had a really good professor in college who introduced me to some fun stuff) I think the early history is interesting because it's also kind of a place of national myths, especially regarding interactions and relationships with the various native political fronts of the time. I think on YouTube, it was Premodernist who said something like it is customary for people to think of US history as something relatively recent, and it is as a nation, but also the context and history of it is something that ties into longer traditions and cultural stuff that is fascinating to look at from an international context as well. I haven't been as Into It as I used to because I'm not longer in school for that and also North American history tends to be grim in a way that hits closer to home than other subjects do due to proximity of time and geography. But it's very fascinating, even aesthetically...I think in a lot of ways, maybe this is a US thing or others, that 1600s period feels like it's the oldest period people think they can remember when they visualize what "history" is (that isn't literal Romans or cave men), which is often how u get ppl seeing a 1600s dresses and clothing items and going "wow.....so medieval..."
