Agreed. But if you're going to fixate on one era, you could do a lot worse than Roman history.
Other cool eras to fixate on:
- Joseon Dynasty and Sejong the Great in Korea
- Chola Empire - naval empire before navies were really a thing
- Ethiopian Empire - somehow survived with strong empire neighbors
There's a lot of really cool history, Roman history is extra cool though since you can see so much of it in Europe.
