Hey, I'm currently on the last year of high school and I'm required to do a research on anything I want, as a preparation for University. I want to become an historian (medievalist), therefore I decided to write an article about Byzantium, more specifically, about the byzantine political-administrative system and its influence on the modern western state. While it's a high school research, I want to do good stuff, and if I like the subject I can even continue with it throughout my career. Therefore, I'd like to know if someone could recommend me some good books on byzantine history and administration. I already have the History of the Byzantine Empire by A.A Vasiliev, but its probably outdated. Thanks for reading and have a nice day.
