The author puts in a lot of effort to support his argument that the people who lived under the Eastern Roman Empire, also known as Byzantium and Romanía (Ρωμανία), were calling themselves Romans (but also after a certain point Romioi (Ρωμιοί) and Christians though he never mentions that) and that the term Byzantium came later (though he uses the term numerous times). While these are known facts, he goes a step further to claim that they were Romans and nothing else and whoever claims otherwise is a denialist. He argues that Western scholars who invented the term Byzantium did it to downplay the Greekness of the empire (or nation-state as he claims). However, he does exactly the same by claiming that they were Romans and nothing else. He never provides a clear definition on what the term Roman means, suggesting that the Greek orthodox religion and the Greek language are not so important aspects in comparison to someone being self-identified as Roman. However, at the same time he uses at different points the Greek language and orthodoxia as parts of the Roman identity. To add more confusion, he never makes a distinction between eastern and western Romans. It is not quite clear what he makes from the fact that some Byzantines were considering their ancestors the emperors of Rome even though he implies himself that this is rather impossible. Self-identification seems to cover everything else even in such extreme claims and while this is a relatively new conceptual argument he refutes other modern or less modern narratives as denialism. He also never mentions aspects of identity such as customs, traditions, food, architecture, aesthetics, etc, which were all Greek in character. While it is clear that the term Roman started to be used when Roman citizenship was provided to the very same population of the Greek world that previously called themselves Greeks (and ceased to exist when these people stopped to be Roman subjects after the end of the Eastern Roman and Ottoman Empires), he makes strange arguments to support that it was more than a label (which is not false per se) even claiming that the Greek language was Latinised (!) because a few hundred words were borrowed from the Romans (so, was it turkified as well?). He also makes the argument that Byzantium was a mix of different ethnicities but he never says which ones other than providing niche examples such as the Galatians. Overall, a well-researched but overzealous and dogmatic attempt to contradict Byzantine scholarship and existing knowledge but without making a specific and clear contribution on what is meant by Romanness of the Byzantine Empire and how we should interpret it.
